After working with our current OHM RepRap design, I believe there are a few areas that could be improved. The major improvement that should be made is to the extruder. There are many times when the extruder stops doing it's job in the middle of prints. This creates for frustrated users. The design could be improved by creating a locking mechanism to keep the idler in the right position instead of held in my screws that wiggle themselves out over time.

It is amazing to see where 3D-printing is expanding to and how many different areas it can be applied. Today I found this article that really exemplifies how broad 3D-printing can be: http://www.theverge.com/2013/4/5/4187568/scientists-produce-synthetic-tissue-capable-of-transmitting-signals-like-nerves
In this article synthetic tissue is being printed that will include the ability to transmit long-distance electric signals much like nerves. With further development, such 3D-printed networks could help facilitate drug applications or help support failing tissues. This product also lends itself to artificial life forms or replacement organs. Though this will not be in use for a long time, it is exciting to think of the possibilities that it presents for disabled people.
Blog 10 (April 5, 2013):
After looking through everyone else's blogs, I realized I could be more thorough in my responses. Adding extra content such as links to more 3D printing options and basically doing more research would help my blog be more insightful. I could also make my blog more user friendly and attractive by using more of the linking options given in the set up.
Blog 9 (March 29, 2013):
I read this article that describes 3D imaging software: http://www.3ders.org/articles/20130326-autodesk-announces-recap-create-3d-data-from-photos-and-scans.html
This is just one option for the developing 3D modeling world. Another is the NextEngine 3D scanner, which is one we have in the lab, it is an inexpensive alternative but you also sacrifice quality. From my experience using the NextEngine it was difficult to get a quality scan even on the highest quality setting. A 3D laser scanner produces dense point clouds containing millions of points that provide incredibly detailed 3D color images of large scale geometries. Another option is a coordinate-measuring machine which measures the physical geometric characteristics of an object. With a laser scanner it works similar to the coordinate-measuring machine using physical dimensions. A photo scanner uses pictures pasted together to create a 3D model.
Blog 8 (March 22, 2013):
Instead of looking outside for new ideas and sources, this week I will look to my classmates for their opinions on the where 3D printing is evolving to.
Joesph - I think Joesph's response to blog 6 was interesting because he talked about the President's message reaching businesses. I had not thought of the citizens that make up all of the industries that are in this country.
Bill - I think Bill's response to blog 6 was insightful, especially part C that talks about the use of 3D printing in the educational system. I agreed that 3D printing should be continued to be used to promote hands on experience. I would definitely suggest that at least at the college level that open source machines should be used to allow for different experiences with 3D printing. I liked the comparison that Bill did for classes like ours and classes that use commercial printers.
Blake - I found Blake's response to blog 6 different in the fact that he addressed the aspect of reliability of our machines. This is actually a really important factor if you want to use the machines for a steady supply of pieces to use as demonstrations in class.
Matt - I think Matt's response to the prosthetic hand idea was thoughtful. He made a great point about being able to customize the design to each person and allow them to print new ones once the they have out grown the old ones.
Alex - I found it interesting that Alex thought the closed-source option would take less time than open-sourced. I thought with more ideas flowing there would be a quicker turn around time for getting a design together. But I could also see with so many heads thinking their idea is best it would be difficult to nail down one design.
Mark - I thought Mark's comparison of the open and closed source hand replicators was very thorough. He made it clear the advantages of each hand model. It was nice to see the many aspects of each source project and the examples.
Blog 7 (March 8, 2013):
Looking through the following projects:
a) Formlabs is currently being sued by 3D Systems for infringement of a patent relating to how the startup’s light-based printer operates. The 3Doodler is becoming a popular idea because it's a new and exciting way to make pretty much any object you can think of.
b) Kickstarter is definitely the best and most promising glimpse at crowd-sourced fundraising. This seems to be the most effective way to get the public's opinion and support for a project. This allows greater spread of ideas from sources that would normally not have the opportunity to share their products.
c) There are a few drawbacks that I can see involving Kickstarter. One drawback is that when you're in a store you can see and touch exactly what you are getting. On Kickstarter, there is no guarantee that the product will turn out as first thought. Compared to a regular storefront, Kickstarter is also impersonal in the fact that there is no human interaction. A Kickstarter entry just has to hope that you understand their product and cause.
Blog 6 (February 23, 2013):
a) The “Disruptions” article predicted the future for several areas of industry and education. It is really exciting to see how many different opportunities are being developed to utilize 3D printing. The article went into detail about even the president encouraging this new technology as well as how it could revolutionize the construction industry and America’s classrooms.
b) It’s great to see the president sharing this kind of technology with the entire US population. Many don’t know 3D printing is something that is becoming well developed, so it is important that this information be shared to further expand the ideas that come along with it.
c) With UVA’s plan to incorporate 3D printing is exciting for the field but might be flawed. The major flaw I see is that after these students go through this training it will be difficult to adapt to a real job. Most employers will not have a 3D printer to help visualize a problem.
d) I like to think our printers will help us learn about more than just what we print. I learn a lot by being able to tweak parts. The UVA printers look very hands off but with an ME degree they should be looking to explore the machines. I think our machines would be a better option for learning purposes
Blog 5 (February 16, 2013):
After reading: http://www.publicknowledge.org/Copyright-3DPrinting a) Revisiting my first blog, I went through each item and determined their copyright and patentable elements. The first item, a bottle opener, could be patented because it is a useful item. The second, a cat bus, could be copyrightable because of its creative aspect. The third object was an intricate vase and would also be up for copyright. The fourth item is a stegosaurus costume and is both copyrightable and patentable. The bottom connector is a practical object for a string of lights whereas the actual light cover is more artistic and would be copyrighted. The last item is a goey monster which is purely a copyrightable item.
b) I found one classmate’s pick that was the copy of a .38 shell, this would be a patent infringement for the design of the shell. Another classmate’s pick is a possible copyright infringement for a boardgame.
c) licensing of non-copyrightable files: In terms of legal usage, it doesn’t really make much sense to license something that has no protection on it. I think many would see it as unnecessary to go through with paper work when there is no law stopping them. In terms of culture advancement, licenses of non-copyrightable materials is important to let the public know that the author or creator has spent time on his creation and wants to keep it his own.

It’s refreshing to see people helping each other. A huge part of the open source attitude is selflessness. I love the idea of 3D printing prosthetics for kids. They grow at such a rapid rate that getting new limbs as often as they are needed is expensive for any family. 3D printing limbs will open up many opportunities for kids around that world that are born with disabilities. I think making this project open source was a great idea. The major benefit to open source is collaboration. You get ideas and input from around the world. The major drawback for open source is finding funding. I think we could help by testing the print files or testing the infill strengths. We could also try to expand the current project to our local area and come up with designs for local kids in need of prosthetics.

a) After watching this tedtalk: http://tedxtalks.ted.com/video/TEDxOjai-Behrokh-Khoshnevis-Con
This is a really neat idea and shows a really promising future for the construction industry. This can help improve the quality of work done by builders to ensure a good product for new home owners. Although he touched on the fact that 3D printing a house would open opportunities for elderly, it also takes away the opportunity for all the hard labor workers to find jobs quickly. 3D printed homes could also help to develop 3rd world countries.
b) After reading these articles: http://www.cnbc.com/id/49348354 and http://www.upenn.edu/pennnews/news/penn-researchers-improve-living-tissues-3d-printed-vascular-networks-made-sugar
It is crazy and amazing to see what we can do with 3D printers. It's a little freaky and sci-fi to think that we can incorporate 3D printing into the medical field. I don't know if I would want fake organs in my body to be honest. It is a great opportunity to live longer but it's also taking the human out of being human. We are turning into machines and it's a little scary.
c) After reading these articles: http://www.digitaltrends.com/lifestyle/300k-3d-printed-burger/ and http://techland.time.com/2012/04/09/the-delicious-future-3d-chocolate-printer-finally-available-for-purchase/
Now I know we're in the future. I am extremely curious about the taste of this meat. If I had money to spare I would definitely be first in line to try out these burgers. It's weird to think maybe one day all of our food will be produced in this way.
d) After reading these articles: http://www.popsci.com/technology/gallery/2013-01/iris-van-herpens-3-d-printed-fashion-line?image=0 and http://www.dazeddigital.com/fashion/article/15493/1/qa-iris-van-herpen
The fashion industry could be greatly customized using 3D printing. It would be really amazing to walk into a store, upload your measurements, and a couple hours later have a perfectly fitting outfit created just for you. This might be a really expensive option at first but eventually could be a great feature for people who are not the cookie cutter shape, like me!
e) I also found examples of Biotech in the way of printing prosthetics. This could make limbs cheaper, customizable, and more available to disabled people. This would be a really inspiring innovation for 3D printing; it would give the opportunity for people without limbs to feel semi normal again. The scariest option I found for printing is weapons. If everyone could print their own weapons, this world would be a very scary place. I really hope this never becomes a real thing.

After watching the first computer mouse demonstration: http://www.youtube.com/watch?v=JfIgzSoTMOs
As a user that grew up with the modern computer mouse, it’s almost comical to watch the movements of the first mouse. It’s amazing to see the transformation that has occurred. Watching the first mouse, I noticed a couple features that`1 are the beginnings of today’s mouse. These include the ability to place the cursor any place on the screen with smooth, fluid movements and the ability to copy and paste a certain area of text. I feel jaded by modern technology to give an opinion whether the demonstration was impressive or not. I’d rather say it’s impressive how far the computer mouse has evolved. I don’t think I would have recognized the importance of this work at the time because I usually don’t have the newest and greatest technology; I wait for the technology to be common and then buy into it.
After watching: http://www.youtube.com/watch?v=Wbl7JEJNTJM
Doyle believed the mother of all demos was a fake. We should share information to expand general knowledge. The population is generally greedy, because we are taught to be. But in a perfect world, there would be no money to worry about so there is no reason not to share information. We could better share information by keeping everything open source. Patents are good for knowing who first created the idea, but beyond that it should depend on the initiative of the entrepreneur to make money from the idea. If people were selfless this would be an easier task, until then it will always be about money.

Exploring thingiverse.com, I found some interesting creations.
Something useful: Shotgun/bottle Opener
Something useless: The Cat Bus
Something beautiful: Thayer Vase
Something funny: Stegosaurus Dinosaur Costume
Something scary: Goey Monster
In response to this article: http://www.salon.com/2012/12/30/the_tinkerers_how_corporations_kill_creativity/
I would consider myself a tinkerer, as an engineer this is an important skill to have. Many of my friends are engineers as well, so I would consider most of them to be fellow tinkerers. I don't like the corporate culture interfering with most aspects of my life, let alone my tinkerer abilities. Many young people today have similar feelings; I hope there will be a change in the future, giving that my peers do not just follow suit as soon as they get in any sort of power position.I also find it funny that Steve Jobs started as a tinkerer and his later products prove to be anti-tinkerer.
In response to this video: http://www.cbsnews.com/video/watch/?id=50138327n
I believe the principles Kelley pushed were diversity, intuition, and empathy for the consumer. We can definitely draw from these to improve our work in the 3D printing lab. We have already dug into diversity with our groups. Many of us have begun playing with the machines by pure intuition. We could develop empathy for the consumer by making the 3D printers easier to use and advertising to make the vocabulary more familiar to the public. It was neat to see Kelley has also jumped into the 3D printing world.
