Blog 7: Light Piping in 3D Objects


1. After watching the video and reading the short article on Disney's Research in 'printed optics', I don't quite understand how this technology could "potentially replace LED and LCD screens to display information on smaller interactive devices". Does this mean that large screens will not be in existance, or that the large screens would still use LCD and LED technology? I don't know how many applications this technology would have because, at least from what I saw from this video, once many 'pipes' are involved in creating one picture, the resolution/detail is reduced. So I can't really see this technology comeing into play for a TV or an iPad, for example. It seemed like when there was a single pipe for light to travel through, the resolution and accuracy of the light path was very exact. This would mean that the printed object would also have to be pretty exact with little to no flaws. This would mean that a very precise and high-tech printer would be needed for this. The printing alone would be pretty expensive and time consuming, because the print is stopped periodically to insert electronics.


I don't think objects will be able to be mass produced with this technology, because it seems very intricate and delicate. Even after a part is printed, it needs to be machined in order to have the intended precision, which would also be costly for mass production.


2. If we were to use the printers at our lab, we would run into the issue of precision. Our current printers are not capable of printing such small objects, such as pipes, with great tolerancing. I also don't think that our printers would be able to create the dense portion of the object without any flaws. If there is a pocket of air, light shone through the object would probably reflect off of that air pocket. I would think it would also be hard to stop a print in order to put electronics in, and then place it in the exact spot it was in to finish the print.


3. I used to play a game on my computer called Pipe Dream, where you had to connect the correct pipe pieces in order for liquid to flow through the connections. I'm thinking you could have different shaped pipes so you could redirect the light in various direction depending how the pieces are arranged. At the moment I can't think of an application for this. It would be really interesting if a 3D model could be printed out of a malleable substance, so you could stretch the pipes without distorting them and redirect the light that way. I was thinking of using this for a keyboard, or for something where buttons are pressed. If the button was made out of this material with light piping incorporated in it, when you pressed a button, the pipe would expand and allow more light to pass through.

Blog 6: Healthcare Applications for 3-D Printing


1. I think the concept of printing skin cells and fixing a wound on the spot could positively impact the medical world by helping patients heal faster and potentially heal with minimal scaring. In regards to printing organs, I think that this could be trickier. Is there a universal organ that would be printed with the patient's cells? Is there a specified size it would print? What would be the implications if the body rejected the new organ?


The 3-D printing of tissues could be beneficial to drug companies as they test the effects of their products, but would they charge less for the drugs if they cut research costs? If so, this would be great for patients and people in general. This would mean that more people would have the potential access to the correct medication they need, which would hopefully decrease the percentage of sick patients, at least in the middle and lower classes.


2. This phenomenon of bio-research has the potential to extend to the RepRap community, but I think this could be very dangerous. First of all, I don't know how many cells would be needed to produce something like skin or an organ, so I don't know how do-it-youselfers would obtain those cells. I could also see these operations getting way out of hand very quickly. Once someone masters reproducing skin, they will move on to organs. Once they master that, they might go on to bones. By this point, they have the potential to combine all of these efforts and create limbs, or even a full human! How scary would that be?! Maybe they wouldn't be able to recreate nerves, but in a sense they would be cloning people. And if they weren't cloning specific people, they could be altering the input cells to change the genetic codes, to create whatever kind of person or limb or skin they want! I would personally be against this type of research reaching the RepRap community, but you really never know what the future has in store!

Blog 5: Open Source, Sustainability, and DIY


1. If I was a dedicated member of the DIY gun project, I would be very discouraged at this point in time. If I actually believed that creating an open-source CAD file to produce firearms in one's home was a good idea and would solve some sort of problem in the world, I would push forward dispite all of the road blocks they are currently experiencing. If I believed in an idea like the contributers to the DIY gun project believe in their sharable weapon files, I would follow all of the regulations necessary to make this idea a reality and contact everybody and anybody who could potentially provide them with access to a printer.


2. In regard to the regulation of creating 3-D printed weapons, I do think their production should be regulated somehow. Even though I don't believe that this could actually happen, a good friend of mine is a victim of the shooting at the Batman premier in Auroa, CO and having seen how guns, when in the hands of the wrong people, can change the lives of innocent and undeserving people, I don't believe that people should be able to print their own weapons from the comfort of their own home. Especially if the files for the weapons are already created and potentially tested, it is even easier for people to get their hands on a firearm. Dispite the fact that these weapons could potentially only used once before they melt, one shot is all you need to change a life.

I don't believe that there is any real, effective way to regulate the uploads of these files to the internet, therefore I don't think it is realistic to think that the government, or any orgainization, would be able to regulate who gets their hands on these files. Sure, they could try and confiscate the individual printers so it would be more difficult to create these items, but people would still have the knowledge and potentially the files to create a new printer very soon after.


3. Some other 3-D printable items that have the potential to be prohibited are food and genes. I think there would be some serious consequences if people found a way to print food items, like a tomato or even seeds to grow such items. Then there would be the potential to alter it in any way imaginable which could cause harm to people if ingested. This would have similar effects if people started to print some sort of genetic codes. There is already the possibility to print skin cells for medical use, as well as 'grow' organs, but if this technology and knowledge was brought to the open-source 3-D printing community, the opportunities for altering genetic codes would be endless. Even though this might be far-fetched, there would then be the potential for people to clone themselves or create crazy mutations in their own homes. I would consider something of this magnitude to get completely out of control.

Blog 4: Makerbot's Position


After reading the blog about Prusa's speculations about Makerbot's Replicator 2, I think this has been coming for a while. Like we talked about last week with intellectual property, Makerbot probably knew what they were doing this whole time. I think they set up Thingiverse so people would get excited and post all of their great ideas, trusting that they would somehow get credit and recognition; or at least help other people out who are interested in this sort of innovation as well. Makerbot, it seems, took advantage of these people; making them think Thingiverse was a safe place to share ideas, but then it all came crashing down on the innocent users.


With this being said, I don't think that another 'Thingiverse' site would be immune from something like this happening again. There are always going to be one or two people who ruin all the fun for everyone else. It seems as though Makerbot got greedy and saw all of these genius ideas as a way for them to make a profit. Like the TED talk about everything being a remix, I guess it is the norm for people to get more ideas from the ideas of others, but I think that Makerbot broke the unwritten rule of this open-source 3D printing community, which is that these ideas are for sharing knowledge, not gaining money and noteriety.

Blog 3: Intellectual Property


1. In terms of putting "restrictions" on 3D printers, I don't think that will ever be a successful effort. Since people can design ans manufacture their own 3D printers currently, I think the only way to monitor this process is for the governemnt to locate every printer ever made. I don't think this is a worth while effort because it would be very time comsuming and not very accurate, as many printers may not be "on-line" so they would be difficult to track. I can understand why the government or some other groups might want to monitor or sensor the use of 3D printers, but you can't stop people from taking every-day objects and creating an intelligent machine.


2. Personally, I have a passion for making objects or systems that people interact with everyday more efficient and pleasurable. When someone asks if there is a way do do something easier or if there is a better design for an object, I get really excited and start spilling out ideas. I don't see this passion or telling people about my passion as a way of attracting mates, but I do think that the way people react to what I have to say might make someone more attractive than other people. If someone can't realte to what I have to say or if they are completely uninterested in something I am passionate about, I don't think there is potential for a relationship. To me, in order for there to be a potential for a relationship, the person doesn't have to agree with what I have to say, but they should be able to contribute their own ideas and respect mine.


In terms of making money, it would not be advantageous for people to expose all of their great ideas because then it just gives other people the chance to steal your ideas before you can make money off of them. For example, the woman who invented SPANX knew her idea could be a gold mine, so she didn't tell a soul about her breakthrough idea until she had a prototype and a patent.


3. At the moment, it seems like people still "own" their ideas because people in the RepRap community WANT to give people credit for their ideas. Since this community was formed on the basis of shared thoughts, I do think that eventually it will become harder to give everyone credit for contributions to the RepRap project. I agree that there will be a time when intellectual property will die off because there will bo so many ideas being shared around the world and it will become more difficult to identify who contributed what to the efforts. I also think that people who get involved with this project know what they're getting into. For example, they should be aware that since this is an open source 3D printing community, they will be allowed to use other people's ideas and other people will be allowed to use their ideas. Since a lot of people around the world my be using one person's idea, that one person might not be given credit for their intellect. Unfortunately that is what they signed up for and that's the name of the game.

Blog 2: RepRap Background


1. I think the idea of a 'self-replicating universal constructor' is already possible. The current open source 3D printers that are being constructed can already replicate many of their own parts and I don't doubt that they are capable of replicating ALL of their own parts. The parts in which a rapid-prototyping machine cannot replicate (e.g.screws, electronic chips, motors) are already being manufactured by various companies and I think it comes down to the precision of each print and the ability to print various materials. If this technology can be harnessed for a rapid-prototyping machine, the opportunities would be endless.


2. To me, the phrase 'wealth without money' means that something has value to someone or some group of people (intellectual, emotional, cultural, etc.) other than a monitary value. In the case of rapid-prototyping, I think the value in this revolution is that the ideas and innovations of people can be shared all over the world with others sharing a common interest or goal. This revolution is about knowledge, innovation and design rather than the notoriety of a few leaders. The sharing of ideas allows for the betterment of the project in a short amount of time. With so many collaborators and new ways of thinking, people are now able to replicate items with this kind of device in their own homes if they want to. This project has given the people access to this great technology, that would otherwise be very hard to access, wherever they choose to have it.


3. Since 2007, it is evident that rapid-prototyping devices have made great advances in technology and design. In the future I invision this device to assess its surroundings, identify a problem, and fix it. For example, it would have a database of knowledge of common items and how they are constructed. If an item that it recognises has been broken, it will realize what parts are missing and be able to create the correct parts on the existing broken item.

I could also see this device being integrated with photography. It would be interesting to see if this device could look at a 2D photograph of an item and create a 3D model of that item based on assumptions made by the RepRap.

The article by Adrian Bowyer regarding the background of the RepRap project alluded to the possibility of a device being able to recreate itself as well as assemble its parts. There could be building plans and written steps programmed into a RepRap to allow the device to identify certain parts (with the help of a camera) and place them together to create a working replication.

Blog 1: Thingiverse Exploration


1. Useful: Water Tap Fountain

I think this is a great idea because I know I’ve wanted to drink out of the sink before and it is a messy process. If this device could be easily attached to any faucet for easy drinking, sinks everywhere could be turned into water fountains! It appears in the image that this device is leaking a lot of water, so maybe it is still in the works.


2. Artistic: Trilobite Articulatum

I was so drawn to this design because of how all of the pieces connect so seamlessly. A lot of time must have gone into the movement of this item and I appreciate how it is almost life-like.


3. Pointless: Donut with Sprinkles

I do appreciate that the doughnut has sprinkles and looks fairly life-like, but if I see a doughnut, I’m going to want to eat it. This is evil and inedible.


4. Funny: Bat-Signal

Batman is my favorite superhero and I would find any and every use for this portable bat-signal. Imagine how much danger and crime could be averted with a device like this.


5. Weird: Chick Egg Cup

If I am eating an egg out of this cup, I don’t want it to look like it will start walking away. I also don’t enjoy when my food resembles the animal it previously was. Needless to say, this egg cup freaks me out.
