About Anil Senturk

Mechanical Engineering junior working on the OS3DP project, AKA EDSGN 497D. I think I'm the only international student in my section. I'm hoping to learn alot more about this project so that maybe in the future I can introduce this open source technology to Turkey and its surrounding countries.

Good luck to all fellow classmates.

Outside criticism of our course has suggested that we do not adequately cover design topics or the design process generally, and sometimes further suggests that the content is not adequately codified. An important question to ask is this: Is there a better way to structure class time? Do we need less open lab time and more lecture time? Was this a ‘real’ class? (by whatever definition you choose) What did you learn in it?

I'm actually glad to have taken this class this semester, it's a great technical elective and I personally have completed a serious project for the fist time(not 100%, but physically built) along with a team of great engineering students. All of my other classes like fluids, dynamics, materials, taught me only the theoretical information. For example, I have studied the basics of a fuel injection engine, but in reality I will not be able to fix any car contrary to what many non engineering people would believe. This class enabled me to guide my way through a difficult procedure of building a completely new open source 3-D printer with the aid of TAs and other experienced students. I have gained skills that will always be used in the future, hopefully for graduate school. In my opinion, to make edsgn 497 D a real class, more class time has to be allocated. At least 4 hours a week, in which around %75 of the weekly scheduled time should focus on projects, (research, building, fixing, printing) and the rest should be theoretical, such as the history of open source printing, the technical details behind it, and students should be tested maybe once about those information. However, it should still remain book less, and student should still use wikipedia(rep-rap). It would also be great if students are given the option to work in the labs at their free time(which me and many other people have done), and the amount they spend on the lab other than class period should be recored using the card system, so the grading would heavily rely on how hard the students are working in the lab to complete a project. I will hopefully take this class again in my senior year.


Sometimes, if you’re really lucky and all of the stars are aligned, it is possible to get small contributions from other departments to operate a course. Do you think your own department would have some interest in helping to sustain the course? Can you think of other departments which might have some interest? What relationship would we have to what they are interested in?

This course should be able to serve more students in the upcoming semesters partly because it offers a nice comprehensive schedule(if well attained by the student) to a wide variety of students ranging from engineering(mainly) to design/arts majors. However in my opinion, the course should get the most significant portion of funding and support from the Chemical E, Electrical E, Mechanical E, EScie, Compscie and Matse departments mainly because the building, operating and designing a printer needs the expertise of these majors, and students will be able to physically get involved in the production of a real physical model of a printer, or by simply improving it in any way that they feel interested in. The mechanical engineering department should not only support 3d open source printers, but they should also support the finding of purchasing expensive and professional level printers(Strasys etc) for the purpose of helping students create real plastic models for their design classes(ME 340 in my case) or simply prototyping a design for a research they are conducting. Regardless of what major a student is, just as all of us use regular paper printers, many of us will benefit from using 3d printers(a lot less frequently maybe). I'm not entirely sure about what EE majoring students are specializing in, however they would definitely love to get involved with the circuitry of the rewrap systems, we as all ME majors in our building team had issues with the circuitry of our printer as some step motors and optos acted strangely when the printer was being tested, so the addition of the EE departments interests and students, we will overall be a better team. Chem Es and Matse people could focus on the quality of prints, and work on the process of understanding the physical chemistry behind heating the filament and extruding it, I guess it was a Matse student in our section that was dealing with the addition and development of heated beds, which actually related to his field of understanding. And computer engineering students would be specialized in the developments of software tools/ drivers for 3d printing systems. There are many softwares that we use, and they need improvement that would make them less buggy, and also help the printers work faster. Lastly, as I had previously mentioned in an older blog, arts and design related students (I'm not familiar with the specific majors related to these areas of studies) would absolutely love the use of 3d printers, they will be able to create their design models without messing with clay/wood and other outdated methods for creating their pieces of arts. We as students of the 497D class now know how a 3d printer is made, developed and structured, we also know what we are potentially missing(more people, more expertise, more money etc), so it is up to us to popularize this emerging technology before its too late. I already have (in the beginning of this semester), suggested that I could introduce open source printers at a university in Turkey (if that particular university hasn't been introduced to 3d printing yet).


1) All the designs are engineered to do the same task, converting household polymer and unused 3d printer filament to a brand new usable filament. I think they use a technique that is widely used in the plastic industry also known as the molding technique [1], except these models are smaller and they just inject filament, not complex plastic objects. The more useful machine should be able to both grind and then mold the plastic into filaments, both recycle bot and the lyman model needs the plastic to be shredded separately and it seems that they have not integrated that system into their models, however the filabot team is also developing a grinder system which means that they make the job easier, all you need is milk jugs and other hdpe materials or filaments.

2) Knowing that PLA filaments cost quite alot, this might force the community to develop more of these kinds of machines to be able to save more unused ABS or PLA filament since open source 3 d printers often prints many faulty models taht are thrown away or maybe used as ashtrays. other than that it would be possible to print 3d things without even worrying about ABS or PLA, they can just create their own plastic filaments or simply buy raw PLA or ABS at much costs. It would be amazing if a printer has an extruder connected to a recycling system that also shreds plastic material, this way a juice bottle might be converted to a much more useful thing.

3) I think a recycler is a much more simple machine compared to a 3d printer, all you need would be a heated metal barrel a reciprocating screw and a shredder. The shredded plastic would be dropped it to the barrel, the screw would then force the plastic through the warm barrel causing it to melt, and the end tip would look like our extruder tips with a larger hole at 3mm preferably. Maybe in the future we will develop an extruder that would also be a recyclers.


1)We already have a few faces printed at our lab so it's no suprise to see someone else use this idea to make profit. Almost every family has a family portrait, in many cases several of them scattered all around their homes. So I do not see a reason why the idea of 3D printing of yourself wouldn't be popular in the near future. I guess the idea of 3d printing is becoming a little more popular in Japan as I've seen a new on the web about a Japanese firm printing a 3D model of your unborn baby, the firm scans the mothers womb and then 3d prints a little model of the fetus. ( The firm also thinks that they can furthur expand into 3D high quiality anatomical printing of many body parts for medical students and research. So overall 3d printing would be beneficial for both money making and medical purposes.

2)I would probably like to buy a model of myself, and do that evry 2/3 years until I eventualy become older. It would be nice to to have a model of all my loved ones as well because I think that looking at a 3d model is alot more reaslitic than looking at a camera screen or a traditional coloured print. My parents may find it strange to have little miniatures of their families, they probably haven't heard anything about 3d printing(until I get back home and talk about it), after that they would find it perfectly normal to have mini figures of the family members.

3)In my opinion, any kind of 3d printing business would be successful, especially the ability to print anything at a store like staples, or having yourself get printed. I think the business model that staples follows would be a little more successful than the ones in Japan. They enable you to upload your CAD file on to their system and then you have to option to get it shipped to you, or you can simply visit the nearby store and pick up your item, whereas in Japan you get yourself printed after a long session of 3d scanning, and it looks like they do not offer 3d printing for other purposes. I like the idea of Mkaerbot opening up a store, and letting the visitors to get a single coloured model of their faces at a much reduced cost. In the future, we'll most likely have 3d photo booths as much as there are regular ones nowadays after a long journey of 3d portrait printing companies compete againsts each other. This service would probably be cheapest option available. And ofcourse, many of us will have 3d printers at our homes, either open source of marketed ones just like we do have cameras and coloured paper printers today.


I've gone through a very classic middle and high school education where learning was only made by reading books and listening to instructors with little experiments. I think that its very important to help students get involved in real experimental projects along with their regular education, its a fun way of learning and improving scientific skills. Ardiuno recently announced a pack that includes a few servos some step motos, LEDs and a micro control chip made exclusively for children up to ages of 16. This kit helps students understand the basics of electronics and products like this along with Lego's at elementary and middle school should help students get interested in science and technology related subjects and could possibly make career decisions at an early age. Since all recent 3d printers are built using a little more complicated circuitry students up until middle school could use these machines just to print pre designed object to built scientific projects in their school. This way they can understand the whole process of building an experiment, its not just about buying the parts but building it from scratch would make the students feel more accomplished. Some students that are interested in non science related classes may not find 3d printers useful other than those that have the skills to use a cad software to create artistic drawings and making their ideas into a real printable object. In my opinion, high school students would find a 3d printer to be a lot more useful. Many high school students that are into science subjects already have basic knowledge of electronics. Schools could establish open source 3d printing clubs that would help students build 3d printers from scratch or simply give the students the opportunity to print objects for projects. Again, pre-engineering students would find this field to be very interesting and useful as Garwood gave an example in his article in which a few students created a part to fix a simple design problem in a car. Overall I think its very importance to help students get their hands on any kind of technology that would help them build engineering and scientific skills as young people. Understanding the science of the filaments used in the printing process or the whole circuitry of a printer would be beyond the scope of almost every student until their college level education, but focusing on the purpose of a printer, which is creating real objects. In my case we focused on the creation of objects used for building new printers and learning how a printer works in every detail.


I'm seeing many news about 3d printers and many other types of technologies that are evolving around this area. The open source comminuty works with the fused deposition modeling technology and it is advancing as days pass, however in my opinion FDM modelling will not be able to compete with others kinds of additive manufacturing styles that have already achieved printing resolutions around 10 to 30 microns. Some can also print parts that are integrated to each other that can move relatively. Current hobbyist made printers cannot do that but they are still very useful in printing sturdy PLA or ABS objects without creating a mess. In the future, fused deposition model printers should still be popular among everybody, especially non professionals and small business owners. The more advanced printers such as the ones that come from stratasys or flowlabs could be used by small to medium size businesses that manufacture parts in a local community without using traditional production methods and possibly make contributions to the country by simply dp not want to import parts from China and many other places. However since all the commercially available printers usually take at least a few hours to print an object to its maximum size and capacity, large business owners would more likely choose traditional manufacturing outside the US at much lower costs. There are some high tech printers that use metal powder to create very highly detailed fine objects, NASA is currently testing a laser melting printer. They plan to manufacture small parts for their space shuttles, satellites and many more at lower costs and much higher quality that avoids the use use of welding.If the method succeed they will test their first vehicle that uses small printed parts by 2017. If they succeed, many automobile manufacturers as well as metal processing companies could also use this technology created by conceptlaser to manufacture parts that need greater precision and higher quality. Currently, some models can print with more than one color by using several extruders, in the future, hundreds of colors may be printed by combining different colored filaments, just like ink jet printers do. This would make a 3d printer much more attractive to a regular consumer. However I do not think its possible to create a 3d printer that could print many different types of materials in the near future, we can print different material ranging from plastics to metals however different printing techniques are used and it may not be possible to combine different printing techniques into one machine. The most important and useful aspects of 3d printers could be bio-printing. It is not possible to create body parts other than creating mechanical or metal parts that fit inside the body. Bio-printing can enable scientists to create any body part ranging from hard to soft tissues. We may expect to see commercially available bio printers that research centers and hospitals could purchase in a few decades to help people recover a lot quicker.


1)Public libraries aren't very busy these days as reading books isn't very popular among many people, instead they watch TV shows or gather information from the internet using their cell phones and PCs. Libraries were probably busier a few decades ago as students and many other had to scroll though magazines, newspapers and books to obtain information of any kind. So libraries could be made a little more interesting to everyone by introducing many kinds of technologies, many have computers and similar electronic devices that substitute books. But the primary purpose of a library shouldn't just be reading and learning, it should also enable people produce new ideas and things. So introducing 3D printers to public libraries would not only help the 3D printing technology get popular among many people, but also encourage the importance of using libraries. However using 3d printers shouldn't only be available at public libraries, local governments and organizations should also create public workshops that would enable the general public use 3d printers that cost more than at least a 1000$. Hopefully, the introduction of innovative technologies such as 3d printers would enable public libraries become the hosts of innovative minds collaborating together.

2) I am familiar with most of the libraries on campus, however I usually study at the engineering library at Hammond, the earth/mineral sciences library at Deike and the Pattee/Paterno library. There are a few open source 3D printers available a few minutes away from the Engineering library but they are only used by a few students and are not suitable for someone without the knowledge of operating one. Most Engineering majors would probably benefit from the use of 3d printers, some design classes such as EDSGN and ME340 require students to produce at least a design of an engineering tool or a prototype, and I believe that PLA or ABS is a strong material that could be used to build reliable working prototypes for some designs. Architecture and design related majors also require the production of models, and I remember a friend of mine working really hard on a architecture model, mainly using wood and polystyrene which made their models look rather funny. After having seen wonderful 3d printed objects for this field ("") I believe students that are in field of design would benefit a lot from using 3d printers that could be purchased from 3dtouch or stratasys, which universities should be able to afford. Similarly students pursuing medical or dentistry school could also be provided with these printers so that they can print and examine body parts for some of their classes. Lastly, art majoring students will probably all fall in love with this technology, it seems to be a cleaner and and easier method of producing an art works rather than working with cement or clay. However all students should be given the opportunity to work with a 3d printer, but since a printing process is usually lengthy, the students that could convince the staff should be given the opportunity to use one and others could observe the machine being operated.


I am not suprised by this patent trolling company that just took action about protecting many 3D designes against illegal 3D printing, it makes sense to create such a patent as these days we are seeing several companies like makerbot or form1 succesfully develop affordable 3d printers. However right now a company isn't forced to use this funny 3D printing DRM patent. Just like many other protection laws/patents etc I am pretty conviced that as long as there is a strong open-source community, people will not let this DRM situation ruin our freedom of creating 3D printable objects. Also we haven't seen or heard of any type of software protection made available for regular paper printers of photocopying machines, although a 3d printer has an advatage of creating an object which may seem to require copyright protection, this DRM will not be successful as it defies the primary purpose of using a 3d printer.

In my older blog I gave a few examples of failed copyright situations, if this patent gets implemented, people will be able to hack 3d object or at least replicate them using 3d scanners or making an identical copy on CAD software. It's funny seeing a few patent trolls trying hard to establish a system that kills the primary purpose of using printing.


1) Since the primary prupose of a 3d printer is to enable the user to create an object that they may need, this interesting development would enable us to print parts that are more useful, not just parts to be used for construction of display purposes but lights sensors, motion sensors and imaging. Someone could create anything that uses light optics using these printers. This technique can also be used in billion dollar industries to reduce the costs of simple components, plus the material used are photopolymers that could make components much more environmentally safe by avoiding the use of metals such as mercury.

2) Disney engineers have used the more advanced Stereolithography technology rather than the Fused deposition modeling that we use in our 3d printers. This technology uses lasers to print object in much higher resolution that enables the objects to have such little lights gaps. The FORM1 3d printer that is around 2200$ also uses this technology that is a little different from the ones that we use in our labs, and they have attained printing resolutions of around 25 microns. However I think the advantage of using fused filament technology is the cost of production and the easiness of creating models without using liquified resins that solidify under laser that could be messy. Since there is room for improvements, we can create extruders that could extrude thiner filaments, however we may need new material that could be extruded in such small diameters, maybe we should start searching about extrudable photopolymers. The models we use in our labs will not be able to extrude the rubber materials that has optical abilities as well. We may have to switch to Stereolithography to be able to print interactive models if the current models cannot be furthur developed into such capabilities.

3) If we can improve what Disney Engineers have found and increase the numbers of light gates and reduce the diameters of these paths, using simple optics would help us create anything. I guess we can somehow use this technique and create a more improved touchsensing technology and embed fingerprint sensing technology into one touchpad, this would be achievable by using thousands, or maybe millions of mini light paths. I would like to create an accelerometer that would require one ligth source and a little thin plastic rod integrated inside the accelerometer that would react to any kind of accelerated motion by bending and by doing that, it would transfer the light source into a different location on the sensor and then it will create an output signal of an acceleration. The rod would look like a fiber optic material inside a cube, and in motionless state it would point the light to the center, any distrubance or motion would bend the rod which would make the light point into another part of the the light sensor, the distance the light travels from the centre point would be used as a reference to calculate acceleration.


1) There has been developments in producing different kinds of cells that would create different kinds of tissues.I believe that Organovo is using these kinds of cells and use their bio 3D printer to give them proper shapes that could be used by pharmaceutical companies for better research or to provide patients that may need regenerative treatments. In the existing research, stem cells are modified to transform to different kinds of tissues that would take time. This technology, as far as I can interpret would make the process of building tissues a lot faster by using existing cells. So this is an improvements over the current techniques. If this company is producing their cells from stem cells, it may bring some controversy as some stem cells are obtained from embryos and it may affect its legality due to moral reasons. Otherwise there is no reason to stop science from improving our life quality.

2)I do not think that its easy to obtain living tissue cells created from stem cells, also I think that most of the REPRAP community may not be capable of conducting very complex bioengineering research, this should be beyond the capabilities of people working for an open source community. However researchers at universities or hospitals could possibly use the open source 3d printing technology to make their research efforts on this bioengineering printing technologies by adapting the REPRAP models into bioREPRAP models, hopefully.


1) Since Defense Distributed has gained enough public support as they have raised more than 20000$ dollars after a few failed attempts, I would feel confident about continuing my work. Plus, its technically not an illegal act to produce weapons without violating the law, they are not intended to mass produce it or sell their ideas. I'm sure Stratasys isn't the only company that sells professional level 3d printers. They can find another company, and make sure to keep their purpose of lease secret. Or as Wilson is thinking about making Deference Distributed a company might give them a freedom of doing what they really want to do in terms of researching and producing weapons made from cheaper plastic components.

2) It is impossible to track down each individual on this planet no matter how interconnected we are through the internet and other means of communications. A printer connected to a personal computer without any world communication could print anything that it's capable of. We already are in a community that produces and distributes all sorts of illegal products and substances no matter how much regulation there is. This also applies to a 3d printer community, a 3d printer isn't actually an illegal product however it is capable of producing weapons and other similar dangerous and illegal products. I would actually support the restrictions and regulations of producing anything that could potentially harm a human being. In many civilized countries, especially in Europe it is fairly difficult to obtain a pistol license and yet they are the amongst most liveable countries in the world. Many Americans are tired of seeing new reports of people killing each other as obtaining many kinds of guns aren't that difficult. ' However as I had stated in my previous blog, I think that copyright laws and IP restricts our freedom of thinking, if we could easily distribute useful information it would serve the world community for good purposes.

3) There are other types of weapons that could be printed, knives made from hard plastic could serve a similar purpose. Any printable parts that could be used to consume illegal drugs could face some regulations. Others would include copyrighted products such as electronic components of brands etc.


REPRAP started as an open source project and it's still going on, there is a huge community of contributors and many different models have evolved. However there is no current open source model that could be used by everyone, and people need some technical skills in building these machines. Almost everything we own was produced by a big company that aims profit, and in return we are using good quality products such as cell phones or computers that we couldn't build by our own easily. I think a company like Makerbot aims this, they want to popularize 3D printers by building them completely and shipping them with appropriate software that could be used by almost everyone. Makerbot isn't the only company in this business, in fact a better printer was developed by a group of MIT graduates, (""), this model can print layers that are 25 microns, almost 75% better than the replicator 2. As we see more models being developed by profit making companies we will see a better price range. Even if these machines are closed sourced, they can still help the open source community get ideas from these devices. I don't mind these two companies working hard to deliver a good product to everyone, I think that the idea of being open sourced makes the development process a little slower as there are many ideas floating around. As long as there are two main developers of 3d printers,ones that make money and an open source community, the 3d printers will evolve faster. These two groups have to coexist.

To give an appropriate answer about the Thinkiverse issue, I first tried searching their user terms and agreement so that I don't give a biased answer by only one article. There many websites that hosts user contents such as YouTube, twitter and thinkiverse uses the same industry practices as they are a large website. They actually give the user a license to select while uploading their designs so that others may not use the design without asking the up-loader, if necessary. And apparently Makerbot does not claim ownership of the user created content thus proving prusa wrong. I think we can still use Thinkiverse to upload any files, and if our design is a work of art, we can put a license on it so that people would be aware of the hard work done but still be able to use it. On the other hand, another fully open site could be used to share files openly without worrying about licensed designs.

You may think that I have contradicted my previous blog(rebutting IP), in this blog I think that people could still place a license on their designs on thinkiverse so that others could ask for permission and/or see the designers name on the design itself.

question(i find this more useful than spamming you): When can we start the printing service so that we can gain xp points? and lastly, we are building an ohm and you wanted us not use a part, instead there is a newer stl file, but i couldn't find it on the ohm website, , maybe we as a group should talk to you about this. thanks.


1) Since OS3DP is an open source type of development, we cannot easily predict what will happen to this technology in the future, however since there is a hard working community of thousands of people working on it, I predict that it will start an exponential growth in its development as more people start using it. Many large media companies have applied many restriction techniques in to their products to prevent people from stealing the “ideas” of the ones that worked hard on it. Sony had developed a successful protection software on their PlayStation 3 that stopped piracy, very few hackers had managed to run Blu-ray videogames from a USB drive but it was limited to a few titles and Sony quickly updated their software, and those that kept using the older software weren’t given permission to play their games online and use the PlayStation network system for a better gaming experience. Although this might prove that a multi billionaire company could win the piracy war, they actually ended up with lower sales figures of their system in comparison to their Predecessor product. So this proves the idea that something would more likely to be popular or successful if large companies let people freely scrutinize these kinds of products without the intent of damaging the economic properties company or the owners of the ideas. I would actually like the 3D printing technology to be supported by companies that aim profit. Makerbot recently announced their new printer at a retail price of 2200$, they have produced a much more complex and an advanced product than the ones we have at the labs. Branding these goods also helps it getting promoted to everyone, not just developers and contributors. I’m not sure whether makerbot would patent many of their new ideas or not but I hope that they would let the open source idea continue and help others get inspired their new machine. Since OS3DP started as an open source project, it will continue in that direction, just like Linux that started in the early 1990s and now there are many major brands that use it and still have a community of millions that support it for no purpose of earning money out of it.

2)My first blog edit “About Anil Senturk” clearly describes my objective of bringing the OS3DP technology to Turkey. If I’ll go back to Turkey for the next summer holiday, I will most likely work at a technical university as an Assistant to a graduate student. It would be my pleasure to inform those people about the 3D printing technology and possibly bring them a few samples to attract that community. There is already a large group potentially successful group of students that would definitely improve the current system. In my personal view, someone’s success in their academic or work life shouldn’t be a measure of how attractive they are to a potential husband/wife, so my introduction of OS3DP to Turkey would be beneficial for the community itself, plus I might be known as the Bowyer of Turkey.

3)In my opinion, protecting your own ideas from others is nothing but selfishness. We start our life by learning from our parents, copying our friends and education is free and mostly affordable almost all around the world to a certain degree. I do not think that OS3DP will completely destroy IP, however it will sparkle the idea of free thinking and free sharing to many that actually work on the development, and feel accomplished when they work for a good cause without charging people just because they came up with a good idea. In my opinion the entire world would benefit from letting people share ideas freely, many people would be allowed to improve whatever they feel that needs an improvement. This might actually sound confusing, letting many people share thoughts might create a huge pool of new information but since there are many people with different levels of intellectuality, this would create a natural filter of letting better ideas being used.

question: Do we have to answer your response questions in the discussion bar?


1) We live in a world where it is almost impossible to predict the next decade. No one could have imagined a cell phone with a quad-core processor clocked at 1.5 GHz take high quality pictures and connect to extremely high speed mobile networks back in the early 2000s. So anything that we could imagine at this very moment will most likely be achievable in the future. A completely self replicating device may sound very odd but we are already in the process of building simple 3D printers that could print all of its plastic parts. I find it difficult to imagine a small device like an OS3DP extruding metal components and assembling it all alone without an external interaction. We need to achieve very high temperatures to give shape to metallic parts, finding a technology that would enable this process in a much smaller scale could work together with a plastic extruder to print every kind of part necessary. Lastly I could imagine small robotic arms and numerous sensors and a very advanced control system assembling itself. Further research needs to be done on new type of material processing in smaller scales. It may be possible to build a small robot that could assemble parts together on its own in a pre defined sets of commands. Governments and big corporations may not like the idea of building everything from cheaply available materials. Most companies earn money by putting a lot of profit on building goods and distributing them. Some people are already able to build gun components to improve current firearms as OS3DP owners could print anything they want.

2) Although wealth may just mean money and the amount of valuable goods someone possesses for many of us, it may not easily increase its value without having to work very hard. Bowyers phrase refers to the OS3DP that we have at the labs, these devices just need PLA, a few electric motors, sensors and some metallic parts. After building one, you can easily start printing more of the plastic components that you need so you actually create components without needing to buy them which basically increases your wealth without wasting alot of money. All you need to do is buy these cheap components and keep producing more of the same kind of devices which will increase the output exponentially. If these devices become very popular in the near future, we could assume that all of its users are basically entrepreneurs. Because entrepreneurship means innovation, we will not need to purchase certain goods as we have our own building device. These device currently cannot print everything, we will still heavily rely on the mass market of goods. Currently, these devices are for replicating and developing purposes and a lot more work has to be done to revolutionize the world of creating goods of your own.

3) The OS3Dp project started from only one person but now there are possible thousands that are interested in this project. There are currently websites that describe the history of this project, many free soft-wares and all CAD files are available to print any component of any model. There are many open-source projects around the world and the first one that comes up to my mind is the Linux operating systems. Many people contributed and there are now many types of Linux OSs and useful software available for free. I see the OS3DP project like this, the number of different kinds of models will continue increasing however the most stable and sturdy ones will be the focus point. Along with this, more user friendly and easy to understand websites will be available to public. For this project to be more successful I think an online catalog of PLA components submitted for donation purposes should be created, this way people could purchase these components for very low prices and some money could be made from online advertisements to cover up the costs of running the website. Unlike today, there will be a lot less variety of different models, this would be due to the development process leading to fewer better designs.


FUNNY : Admiral Ackbar got his first fame from the amazing Star Wars series. However people around the internet are pretty good at creating funny memes almost out of everything. I still smile at the pictures with the Admiral Ackbar "It's A trap" meme.

USELESS : Although this design is a little artistic it does not contain the awesomness of a real three dimensional helmet. But it's still a good attempt to look like one of the 300 spartan soldiers.

ARTISTIC : This 3D print got my immediate attention since NASA had successfully landed a high-tech mars rover which weighed almost 2000 pounds. Scientists are now able to study the enviroment surrounding the rover so that the future generations will be able to land safely on the red planet. I haven't seen any Mars Curiosity Rover toys around, so printing these stl files make you one of the very few people that own a mini Curiosity.

WEIRD : One of the few things I can remember about my childhood is my lego set. To make this print complete, you will have to remove the head of a legoman that you own. I would have never though about designing such a ring so that would be reason why I named it a weird design.

USEFULL : I live in a dorm enviroment and the water faucets require the students to lean forward a little bit to wash face or brush teeth. Leaning for over a small period of time causes some discomfort and using this little foutain would greatly reduce the leaning distance which in return would provide a more easier water tap usage. If students are allowed to print something they need, in the near future, this little design would be my choice.
