There is nothing in the first top 15 article that I have not seen before. The most of the items the article talks about are things that will take years to perfect and allow people to actually use. Yes there is entrepreneurship opportunity printing plastic parts for people. Someone could design and sell replacement parts for everyday plastic objects that people can use.
What sorts of strengths and weaknesses do you predict/project, as compared to the systems we currently build?
The printrbot simple uses a string to move the x and y axis. Since the string can stretch it has a smaller error built in that the belts don't have. The issues that the belt cause also apply to the string as well. It also has a smaller bed than the printers currently used. The benefits are that it is smaller, cheaper, and quicker to build.
Why would we want to incorporate this into our printing? What capabilities would this give us. If we could print conductive pathways into objects, what would you try to make with it? How might we try to make it work with the printers we use?
If this is incorporated into our printers we could print the circuit boards used on the printers. If we could print conductive pathways into objects we could print some of the basic electronics into some objects to allow for a better replication right off the printer. The dual extruder printer could be modified to so that one nozzle prints pla and another prints the conductive material.
What are the strengths of a platform like OpenScad? What are the weaknesses and limitations? Would you ever be tempted to use it, or the process of turning images into models shown above? If so, for what?
The strength of the OpenScad platform is the free price and the semi-easy to use system. It seems to me like the major weakness is it's ability to handle complex shape and how sensitive it is to formating issues, like extra spaces. I have been tempeted to use it since it seems like a cheap and quick way to make basic models.
Now that you've had some experience working with the printers, what are the things which have frustrated you the most or occupied the majority of your attention? Mechanical problems? Software? Wiring? Construction? Describe some issues you have encountered and what you did to solve them.
On that note, also describe any problems which you failed to solve or gave up on, or are still working on. What's wrong, and how else might we try to fix it?
The biggest thing that has occupied my time has been fighting with wiring and electrical issues. Alot of the electrical parts I have used have been bad or gone bad, this was most likely due to a bad arduino. Another issue I have had with the black printer was fixing the shifting in the x axis. I have tried tighening the x axis belt, adding the extra bearings to the extruder carriage and increasing the voltage on the x axis motor. Neither of these issues have been fixed on the black printer.
Do some research into Jeffrey R. Immelt and Terry Guo. Who are they? What have they each said about 3D Printing? Can you come up with any rationale for why they might have the opinions which they express?
Jeffery R. Immelt is the CEO of GE. He said that he believes that 3D printing can help the manufacturing business in the US. He would have said this because his company would benefit greatly from a cheaper manufacturing process and closer manufacturing to point of sale.Link
Terry Guo is the founder and President of Foxxcon a large manufacturing company mainly in China. He had very negative comments to say about 3D printing saying that he believes it's just a fad and interest will fade. He would said this because 3D printing is bad for his business. His company specializes in large scale manufacturing of objects with cheap human labor. If 3D printing takes hold his company would lose business since the objects could be manufactured by robots in any country and any factory. Link
What is good about this? Anything negative? Can you think of other things which might be made using these design principles?
The good this about this idea is the ability for people to create and repair everyday items. It also always for people to modify their devices to fit their needs. The negatives are that if your devices don't work then your on your own to fix it. A lot of every day devices can be made to follow this like a vacuums and coffee makers.
Describe the differences between making 1, 10, 100, and 1000 of these objects (scroll down) Is this over-elaborated by Jesse? Can you state what is described in these images as a design/manufacturing principle?
As the quantity goes up the cost per item goes down. Except for 10 units which actually goes up in price. The other trend is that as the quantity goes up the precision goes up and labor intensity goes down. I believe that the comparison is a little over elaborated by jesse, before he started he would have had a general idea of the quantity. He could have put a little more detail into the quantities 1 and 10 since those are self built and kit built, and those will be the major distribution of this product.
A. The Four projects from the AMRI
Thermoplastic laser sintering Using a crushed thermoplastic powder and using the selective laser sintering technque to 3D print
Open Sourced DLP Printer Creating an open sourced printer that uses UV light to cure a photopolymer resin.
Ink Jet Printing bacteria Refining the ink jet printing technique for use in printing bacteria
Cell Struder for Synthetic Studies Using a syringe to print cell structures.
They all have important values the two biological printer could be of important value bacuase we already have plastic printers but no real good way of printing biological materials.
I feel like we ccould do our own studies into different methods of printing like selective laser sintering, digital light projection, stereolithography and many more. We currently only use fused filament fabrication and diversifying our printers could allow for future studies into a wider variety of topics. We could also look into modfying the printers to handlke a wider variety of materials.

This article is about a 3d printer that can make pizzas made by systems and Materials Research Corporation. The major hope to this article is the future ability to 3D print food. With the ability to 3D print food the entire food service industry would be affected. With the new technology a new type of vending machine could be created to serve a wide variety of hot food. A home version would allow for people to program in their food choices and have their meals ready for them when they arrive home or get up. The ability to create good food on a printer would allow for many people to have a healthier and a more balanced diet at a lower cost. The possibilities are unlimited with a good 3D printer that can handle food. The hype from this article the current state of printing food. From this article the 3D printer used dough, ketchup and cream cheese to make a gross pizza. Their is also a lot of future problem to that need to be solved for the ability to 3D print for to be mainstream. The major problems are the ability to properly heat the food, the ability to store the food components for extended periods of time, and the ability to quickly make the food. With foods that need be cooked would the printer make the food already cooked and then heat them or make the food then cook it completely, with some uncooked for you could have sanitation issues. Food gos bad how long would the food components last before they need to be used of thrown out. No one wants to wait a long time for food so the printers would have to be fast. There is great potential in the future of food printing but for now the hype for outweighs the hope.
In my blog 5, I didn't point out the distinction between copyrighted and patented objects. I think Matt did a great job of pointing out the difference between two from a useful and artistic view.
Ian did a good job of pointing out how the copyright and patent laws are different from country to country. He also pointed out how some countries don't have any copyright laws like China.
The nude model, the split skull, and the exclamation point from my first blog both have copyright elements to them . They are creative objects with no useful purpose.other than to be displayed. I feel like the nude model and split skull could easily defend any challenges since they are unique. The exclamation point on the other hand I feel would have hard time with a challenge since it appears to be a generic design that has been done before The raspberry pi from my first blog is a case of a used copyrighted design since it is a copy of the Nintendo NES,
Good Examples of Copyrighted works

People might be interested in licensing non-copyrighted material for two main reasons. The first being that they want to protect themselves from legal troubles in future. With the license it stops the company from suing them in the future if copyright laws change. The second reason is show that want to be part of the creative culture. A good example of this is the creative commons license. People use the license to show other people that they allow other people to modify and distribute evolutions of their designs
The writer seems surprised that someone issues a takedown notice to thingiverse. With how aggressively companies protect their copyrighted and patented work, it was just a matter of time until some filled a takedown notice. He also sounded surprised someone issued a takedown notice to a “community typically committed to sharing ideas.” Youtube was created for this purpose, torrents are used by people to distribute their open source software, but if someone sued or filed a takedown notice no one would be surprised.
The video talked about how arduino and reprap give away their product and make money from other sources. This allows them to get their product into more people’s hands, than if they charged. This is a common business model for open source products. Since its open sourced people can look through software source code or hardware blue prints and make modifications. This business model is like the one used by Android and Linux. I think this model has potential because other people can look and make modifications and release it. This can be seen with Linux operating systems, people have taken them and added new features, interfaces and other stuff and released it for other people to use like Ubuntu, Linux Mint, Debian, and Red Hat. On the Android side there are many custom aftermarket android operating systems available for people to download and put on their device to get stock android, new features, and remove carrier bloat ware. Major examples are Cyanogenmod, AOKP, AOCP, and Paranoid Android.
Reading other students blogs I came across some that had some blogs and layouts that I really liked, some on the other hand had bits I didn't like or really annoyed me. These are some of the blogs that I liked and didn't like.
I really liked how he laid out his blog, with the different tabs. The tabs gave his blog a very unique feel to it. I also liked this inclusion of the about me section. Other students have an about me section but this one says a lot more about the person, but it also gives a little too much info about. All this information seems to be just too much.
I liked how he put his blog 1 into a table. This gives his blog a cleaner look than other students. With some blog one posts the pictures are on the right side, this can lead to some confusion over which picture goes with section. The table clears up these issues with all the pictures on the right side.
On his blog 2 his response was all on one line for each response. This forced you to scroll to see all of it. It really should be in paragraph format for easy reading. It also had a box around the part of the text. This doesn't have any purpose that I can see. It would be best to remove it .
I didn't like that fact that they have added titles before any actual information. This makes the blog feel incomplete and unfinished, like they have only done part of the actual assignment. It would be best to just remove them and add them as the blogs are completed. Madeline Roche’s also has some weird stuff going on in the extra sections that should just be removed
I feel that his blog 2 is very lacking, it is only a two line response. He should expand on what he has some more. He should give more detail about why he likes working on the electronics and if anything about them he would like to change to add more features, making them more efficient, or simpler to assemble.
He really needs to add a response to blog 2. His blog other than that is fine but with blog 2 due last week it really should be added by now.
It kind of annoyed me to see the inconsistencies with the titles of the blogs. He has Blog 1 and then Blog Number Two, and this is just really annoying to me.
In his blog 1 he had all the links at the bottom under the title of links. These should be included in the response. He should either add the link their or add a link to the links at the bottom, the first choice is the easier and better looking of the two.
Building a 3D printer
- It's interesting to finish building a 3D printer. It takes skills from many different fields to build the printer, add the electronics, and fine tune the printer. Taking the work that someone else has already started and analyzing it to see what needs to be done, what can be fine tuned, and seeing if any changes that be made. Then taking their progress and finishing and fine tuning it. This teaches skills that can be valuable to people when they move into their professional careers. When in a professional career you will not always be on a project from start to finish. Sometimes you have to come in after a project has started to finish it or have to start a the project but can't finish it.
Solar Powered 3D printer with tablet interface
- An interesting project would be a solar powered 3D printer. This would start with analyzing the power usage of the printer, then finding a method for collecting and storing the power, creating a design to hold the solar panels and batteries, and wiring the printer to the new power supply. What would be more interesting is to see if it was possible to connect a tablet to the printer to replace the computer. This would make the entire printer more portable, instead of taking a monitor, keyboard and mouse you would take the tablet. To attach the tablet the printer, the printer design would need to be modified to hold the tablet or find a way to wirelessly control the printer from the tablet. For the interface a tablet version would need to be found, if none could be found then a way to make the current interface function on the tablet would need to be found. The benefits of having the computer on the printer itself would be easy portability you would just take the entire printing unit. The printer would also have a neater appearance that would make the printer look more professional. The biggest downside would be since tablets don't have USB ports a new method for wirelessly loading the designs would have to be used. It would be interesting to take the printer to a busy section of campus and set it down and just start printing. This would attract more public interest to the 3D printing community and possibilities of 3D printers.
- This nude model is called Nude panther V2 by Fanasygraph. The sculpture is detailed and looks like an expensive piece of art someone would buy from an art gallary.
- This split skull by XXRDESIGNS is really strange. To see the face peeling away and revealing the skull is very strage. It loomks like something that would be sitting on a mad scientist's desk.
- This exclamation mark by peterfo is useless. It's just and exclamation mark that sits on a flat surface. I don't any possible uses for this other than a decoration.
- This Smartphone Dock by rubb3rtoe is something I would find useful. In my room I have no night stand and at night I have to leave my phone all the way across the room to charge. With this I could charge my phone in the outlet by my bed and still have access to use it.
Best Raspberry Pi Case
- This case by TBSkinner has alot of potential to be cool. The mini NES holds the Raspberry Pi and allows the front cartigde slot to give access to the SD card. The only problem is with the lack of outputs in the back.
- The only thing that surpised me was how all the raspberry pi cases seemed very generic. To me they all kind of looked alike and nothing really stood out. Other than that nothing else really surprised me.
