About Me

My name is Kerry Brunner. I am a senior in Mechanical Engineering with a minor in Engineering Mechanics. I am currently in section 2 of the EDSGN 497D Open Source 3D Printing class. My only question: why is the earlier class in the day (4:15PM - 5:30PM) titled section 2 while the later class (6:30PM - 7:45PM) is titled section 1? Interesting...

Preface: Check this out:

What’s your impression of this use of 3D printing technology? Would you buy a model of yourself? Would your parents buy one? Explain the merits (or lack thereof) in this business model. How much might competition drive down prices in the future?

Answer: I think this application for 3D printing technology is interesting. On the one hand, it makes a great novelty trinket for families, etc... For instance, my parents used to buy mini ceramic mugs with our family members' names on them. Additionally, we took many family portraits together in years past. I'm sure there are many families across the globe who would love to have a 3D printed model of each member in a sort of "family scene".

Another market for this type of 3D printing would most likely be a younger crowd as the article seemed to suggest. Although I may not purchase one myself, if this trend caught on, I could envision the 'new fad' in middle schools being having a 3D printed version of yourself. Although it may not be a sustainable venture, there could be a big market of teenagers waiting for their personal mini-me's.

Finally, as the article mentioned, there may also be more practical uses for this type of 3D printing. I don't know that we'll see police using technology like this but maybe for a more specific application like casting agents using models to remember specific actors etc, this could be applicable.

I think that these may come about but the technology seems to be pending on an improved scanning system. As mentioned in the article, the scanners can not detect furry materials or shiny materials, etc. Once the scanning technology is improved, there may be many more of these mini 3D people applications.

So, you’re in a class and classroom dedicated to 3D printing - Do you see a place for this in other educational environments (K-12?) What points do you agree with or disagree with in these articles? Support them with something from your own experience. Again, short thoughtless responses will not get full credit. Make me think that you spent at least 20 minutes on this.


Answer: I believe 3D printing will have an excellent future in an educational environment. However, the key word there is 'future'. I don't believe this technology is necessarily ready to be applied at such a young age. Take the RepRap class for example. We use programs like Solidworks, Skeinforge, Replicator G, and Pronterface. We also work directly with Arduino boards and mechanical devices like servos etc. I believe all of these things can be introduced to children at an earlier age. But our educational system is not at a point where the students would be able to fully understand the equipment. There are times when even myself and some of my peers struggle with the concepts of the RepRap equipment. I think that in the earlier phases of these educational programs, the students may simply use the printers for printing parts needed in the classroom, etc and eventually learn the workings of the machine itself. However, I think classes strictly about 3D printing machines are a far off idea.

On another note, I don't know that 3D printing technology has advanced enough for K-12 schools to become interested in the idea. In other words, our technology is still being developed. Because of this, a school is not going to be willing to pay $1,500+ for a single machine for these experimental teaching methods. Especially with schools everywhere undergoing budget cuts and forcing to cut down on extracurriculars in order to throw more money at the math and english departments so their students can achieve better grades on standardized tests, many districts simply do not have the resources to consider such a project. That being said, once the 3D printing technology has reach a point at which it is cheap and stable, I believe the idea of 3D printing in schools will certainly become a feasible idea in which many schools will participate.

As far as the articles are concerned, I believe the entire STEM (Science, Technology, Engineering, and Math) idea is fantastic, and I know that schools across America are pushing for programs like this. Anything that can get kids interested in the STEM topics and also get them to learn something in the process is a great program. Because of this, I once again do foresee the 3D printing technology entering K-12 classrooms, however I beieve it may just take a few more years for the idea to become widespread (which goes against the statement made by the 2 cent worth guy about 2012).

Preface: Now that you know a little more about the different types of 3D printing or other additive manufacturing methods, You should envision scenarios of a future where this technology is more widespread. What sorts of changes can we expect? What sorts of changes might we not expect? I’ve included some links here to give you something to think about, which we’ve generally talked about before. Bonus points when you think of something that I haven’t.

http://www.huffingtonpost.com/daniel-burrus/3d-printing-additive-manu_b_1951777.html?utm_hp_ref=tw


Answer: I believe there may be a huge push for 3D printing technologies due to its overwhelming environmental advantages. The object and parts that we can now manufacture are incredible, yes. However, I think that the true reason these technologies haven't become more widespread is because it is still a developing technology. Still, in a world where environmental impact is consistently on the news and regulations are restricting companies more and more, the idea of less waste along with the design flexibility of a 3D printing machine will push it to the forefront of the technologies in years to come. Therefore, although the capabilities of this technology can produce things such as printed organs, customized toys and home decor, and replacement parts for appliances, etc... I believe we will see more changes in the manufacturing processes of large industrial companies before we see the more personal improvements in our daily lives. These companies have the money to fund research in 3D printing, and if there is a 'technology pull' for this type of manufacturing, I'm sure we will see these changes sooner than later.

Now, that being said, I believe we can also expect changes in our personal lives as well. For instance, as stated in the articles, we may be able to rapid prototype replacement parts for our cars in the future. These possibilities are essentially endless once the technology has expanded to support such an idea.

Discuss the suitability of libraries as hosts for RepRaps (or other 3D printers)

We have a number of libraries on campus, as well as the one on allen street: How many are you familiar with? Do you think any of them would be suitable for this?

Answer: This idea is fascinating to me. One line stands out in all of these articles: "The biggest mistake we made is when we let books crowd out the users and libraries became a quiet place where there's no talking and no food and drinks," Colegrove said. "We need to adjust from having conversations in users' heads to a collaborative environment." I believe this topic is two fold as I will explain below.

1) Hackerspaces in Libraries

So, a few of the articles above mentioned a new idea of Hackerspaces in public libraries. The thought is to bring libraries back to their 'roots' in the sense that "If you look back at libraries over 2,000 years -- including the Library of Alexandria -- you'll see that they were involved in buying technology that many people cannot afford and making them more accessible," Colegrove said. "Along the way, it became all about having the biggest and best book collection so you ended up having identical libraries. We lost our way." With this new era of digital technology and digital information, the idea of the library as a means of storing knowledge in the forms of paper books is becoming less and less sustainable. Libraries are now looking to other ideas to simply stay in business, one of which is creating a public Hackerspace. I believe this is a fantastic idea. Libraries are meant to be a resource for people who need it and can't afford it on their own. To have 3D printing machines in a space which would be open to the public would allow many people to perform tasks which they would not have been able to do previously.

Unfortunately, there are downsides to this idea. I fear that in a large city, these services may become abused. For instance, many people would want to print practical things and potentially important things but if you open this technology up to everyone, there is a large possibility that the use of the machine would become backlogged with orders that may be more for fun than for practical applications. This may deter people from actually using these Hackerspaces for productive purposes if they have to share it with people of less productive motives.

Another fear I have is that these libraries may not be able to fund and sustain such a technology until it becomes cheaper. One of the articles spoke of a $20,000 Stratasys uPrint SE Plus professional-grade printer -- a small price for a university, but for a public library to carry this cost would most likely be impossible. Many libraries could probably search for grants etc as the library in Fayetteville has done to create their FabLab. However, I don't see every library in every small town across America being able to sustain this type of technology.

2) Academic Hackerspaces

A more sustainable type of Hackerspace in libraries would be academic Hackerspaces on University properties across the country. As one of the articles discussed in detail, 3D printing specifically can be applied to many different academic programs including Chemistry, Mechanical Engineering, Computer Sciences & Engineering, Mining Engineering, Geography, BioSciences, Business/Engineering/Physical Sciences, Seismology, and the Arts. A Hackerspace of this nature would definitely be utilized by students and be very useful for academic advancement as well as personal growth.

Unfortunately, there are disadvantages to this as well. Once again, at large Universities, I am afraid that the backlogged list of projects needed to be printed would be huge. There would need to be restrictions on who could use the different labs per major etc. That being the case, I believe we already have something like this on campus. In engineering, we have the Learning Factory. It is not a 'library' space by any means. But it is a shop where we can go to make whatever we want -- as long as it pertains to a class or a project in a class.... Similarly, the theater department has a shop by Pollock where they construct their sets and have many tools necessary for a Hackerspace. Even the arts department has a wood and metal shop near Forum for them to be able to work on projects. The issue with all of these is that they are not open to the public for people to use on whatever project they please - there are restrictions on who is limited to work in the shops. Unfortunately, I believe these restrictions are in place for good reasons. I feel like if the shops were open to everyone, it would be a madhouse and people who actually needed to get stuff done would not be able to (similarly to in the public library discussion).

So as far as putting a free Hackerspace for everyone to use in one of the libraries here on campus, I don't know that it is necessarily a practical idea. Maybe for a smaller university, or a limited group of people which once again, we sort of have here at Penn State.


Still, if we are strictly discussing 3D printers in venues such as libraries, I feel as if something like the Engineering Library in Hammond may be able to host such a thing. All it would require is the implementation of a sound proof room so as to not disturb the studiers. And once again, this is already in place in the Engineering department's Learning Factory. The main issue - its not open to everyone (for good reason).

Preface: Check out this: Link to Awesomeness. Most of our discussions have discussed printing object which are not alive, however many researchers are now looking into using 3D printers to create different organs or other bodily components. The NovoGen MMX bio-printer could change the field dramatically.

Question 1: What do you think of bio-printing? What sort of legal problems or technical problems can you foresee?

Answer 1: Bio-printing technology may have many benefits. As listed in the article, it can be used for medical purposes such as printing organs for placement in human patients who may require them for health purposes. It can also be used in testing for pharmaceutical purposes. This will give pharmacists a more accurate portrayal of whether a medical will actually work in the human body and the idea of bio-printing will reduce the need to use humans as test subjects. Unfortunately, this technology may come under the same scrutiny as the topic of tissue regeneration. Bio-printing merely prints tissue layer by layer, and tissue creation has been an upcoming technology for many years now, see this video on tissue regeneration. However, I'm sure there will be political repercussions for these technologies. As mentioned in the video, the stem cell transplants that the paralyzed gentleman used were not available in the United States. These are the type of regulations that many countries will put on bio-printing at least until it is a proven, safe, and repeatable technology.

Question 2: Do you think this might be extended to RepRaps for DIY bio-research?

Answer 2: I don't think bio-printing will ever be extended to RepRaps due to the fact that the testing on these machines needs to be extremely precise and must be performed under controlled conditions. I think the RepRap community needs to become a bit more controlled before bio-printing will become a RepRap reality.

Question 1: Imagine that you were a dedicated member of the DIY gun project: What might you do now?

Answer 1: I would probably do the same as Cody: attempt to get a gun manufacturer's license and keep trying to find loopholes in the law. If he is as dedicated to this project as he seems on paper, I'm sure he will be able to figure out a way to make this work.

Question 2: Another article asks ”Should 3D printing, especially when it’s being used to create items like guns, be regulated? Can you regulate it?” Check your Blog #3 Questions 1 & 3 (and my comments to them) if you haven’t already. Do you have any more to say about this issue of 3D printer regulation (gov’t or corporate)?

Answer 2: I believe that there will have to be some sort of regulation. With every new invention or process, it is human nature to try to at some point make a profit off of it. I mean if I devoted all of my time to a certain project, I would surely want some compensation for my time. Even if I were to just do it for the enjoyment, if I am doing it full time I will need to have some sort of income at some point. So unfortunately, I believe that with the desire of profit comes the need for regulation. However, "need" is a strong word. I think that its just the way our society works, specifically in America, that in order to live the American dream, it needs to be ensured that no one will steal that dream away from you. I hope this answers the question, I may have gone on a slight tangent but hopefully this illustrates my feelings on the subject.

Question 3: Guns (and other weapons) seem to be prone to prohibitions. What other 3D printable constructs might attract similar attention/derision/prohibition?

Answer 3: Any sort of item relating to drug paraphernalia would probably draw legal attention, yet I don't know that too many people would actually spread the code for something like that... Probably just keep it to themselves I'd guess. I think that maybe other items with strict copyright laws attached to them might fall under some form of legal lawbreaking. In addition, any property of the government's would surely be illegal to spread on an open source website like Thingiverse.

Prompt: Comment on Makerbot’s position (as far as we know), Prusa’s concerns, and ownership of designs. Should we look for a new thingiverse?

Response: Hmmm well I think Makerbot has every right to go closed sourced. If they believe their ideas are being taken and the feel the need to protect themselves then they are allowed to. Unfortunately, it puts many other people in a bad position. RepRap ideas, being open sourced from the beginning, have been passed on to hundreds, thousands of different people and it seems hard to all of the sudden tell the community that the Makerbot Replicator 2 as well as all of their ideas on thingiverse (potentially...) are no longer public property and instead that of Makerbot themselves. It does not seem fair that a project that was pushed forward by so many minds is now being kept closed by one company. It seems like they took so many ideas, benefited from them, and are now keeping them to themselves. However, if they are trying to make a business out of this industry, it would be much easier for them to create a closed sourced printer, so I guess that's what they did. As far as the ownership of designs is concerned: I think its ridiculous that this was even in the Makerbot Terms of Use. Still, if it is true, then I guess the users of Thingiverse are liable - they technically should have read through all of the Terms of Use before using Thingiverse and if they did not wish to agree then they should not have used Thingiverse in the first place (not saying I agree with it, but if that's true then what can people do?) As far as searching for another Thingiverse: I think that we need to first see where this whole legal debate takes us. If in fact the prints on Thingiverse are Makerbot property then sure, lets try to find something else. However, maybe this will turn out better than we originally though. I think right now its a waiting game to see where Makerbot takes this, then we can decide where to go from there as users and RepRap members.

Question 1: It seems that 3D printing isn't going to disappear, but the exact nature in which it will develop is not well defined. On that note, we currently place restrictions (DRM) onto our media to control distribution, with limited ‘success’. Do you think this might be applied to 3D printing? How or why not?

Answer: I believe this may eventually be applied to 3D printing. If I understand the concept correctly, it seems as if the new Makerbot is in fact potentially closed sourced. This will incite a series of patent laws and other legal actions in order to ensure the Makerbot is kept under these laws. However, I don't believe that the 3D printing industry can ever be completely restriced. Take the music industry for example. In music, people can buy a guitar, listen to a song, and copy it or come up with their own version of the same song. In 3D prining, anyone can buy an existing printer and then make their own printer by printing the parts themselves! This is why the music industry has faught so hard to try to improve the copyright issues and if 3D printing puts more restrictions on their products, they will most likely run into the same problems. In his video, Kirby Ferguson mentions the initial goal of Patent Law: "To promote the progress of useful arts." Are these restrictions really helping that cause? I agree with Kirby and think that our society is growing further and further away from this idea as we delve deeper into the restrictions put on our industries. For reference on the closed source Makerbot issue please read: Open Source vs Closed Source


Question 2: According to Bowyer, many people have a great idea (or perhaps a passion) that they love to tell people about. What is yours? Do you see this as a way to attract future mates? (or to get money?) Why/why not?

Answer: Hmmm, well I have always enjoyed telling people of the very diverse set of activities I am in. I currently am involved with numerous extracurricular groups on campus (some engineering related and some not). I believe that this is a great quality to have and shows the wide range of talents I like to think I have or at least the wide range of organizations and activities I find enjoyable. A far as a way to attract a future mates: I can't think of a specific instance in which I asked a girl out by saying "hey look at all this stuff I'm involved in!" However, I do think that its a good quality to have and I look for the same in a potential girl. So, yes I guess in regards to relationships, I think that my passions highlight a unique and attractive (ladies?) side to my personality.


Question 3: Professor Bowyer seems to think that 3D printing will finally kill intellectual property, and he sounds pleased about it. Do you think he’s right about ending IP? Is this a good thing, a bad thing, or somewhere in-between?

Answer: I don't know that it will completely kill off intellectual property. I think that some members of the human race will fight to the death to keep intellectual property. However, others are all for open sourcing everything. I think that open sourced projects are extremely useful and can push technology forward much faster than without collaborative teamwork. Yet, intellectual property is just so darn useful when you come up with an idea and are trying to make a competitive company out of it. Without intellectual property it would be hard if not impossible to keep our market-type society alive because as soon as someone comes up with the newest product, someone else will just copy it and sell it cheaper (China?). And although that last quip about China came as more of an afterthought, it is true that in some parts of the world, intellectual property already doesn't exist and they seem to be doing alright. So I guess we will see what the future holds in regards to how intellectual property develops or dies out and how the 3D printing world effects this and is affected by this.

Question 1: Do you think his goal of a ‘self-replicating universal constructor’ is feasible? What remains to be done to achieve this, or alternatively what would prevent such a goal?

Answer: I believe that it will most likely be accomplished in the future; however there are many blockades preventing this technology from appearing too soon. One of the largest problems I can foresee is the difficulty of storage. If you have self replicating machines which will then, once assembled, begin replicating again, a company or designer will quickly run out of space to put all of these machines and therefore the design will not be a truly automatic process. Instead, a company may form to create and sell such an item. Here we run into another difficulty. If a company were to try to market these items, they might be successful at first but would soon lose profit due to the fact that the machine can easily make 'itself' for the user's friends and family. This causes a limited market pull from the customers, not because of an insufficient or unwanted product, but instead because of the ease at which free trading can occur.


Question 2: The phrase “wealth without money” is both the title of his article and the motto of the reprap project itself. What does this phrase mean? (To him and to you if they differ). Discuss implications, problems, and possibilities associated with this idea.

Answer: Wealth without money means acquiring a lot of junk (or in this instance, making a lot of junk). One of the problems he foresees with this idea is that people will begin to make tons of stuff and soon we'll all have piles of useless items. He also mentions that the items don't have to be of good quality anymore because if one breaks, just make another! So although people will acquire a lot of "wealth" no one will have a lot of money or useful things, just a lot of junk.


Question 3: The Darwin design was released in 2007. It is 2012 now. Imagine future scenarios for RepRaps and their ‘cousin’ 3D printing designs (Makerbots, Ultimachine, Makergear, etc.) how do you think the RepRap project (community, designs, website, anything and everything) might evolve in the future? Describe as many scenarios as you can envision.

Answer: I believe that RepRap will eventually expand to larger units, more useful parts, potentially different materials if the technology allows it. Eventually, I believe people will be able to purchase a RepRap kit for their home and use it to make high quality products and parts. I don't believe that a RepRap machine will truly be able to replicate itself completely; however, we have already taken steps to replicate many of the parts needed for a new RepRap machine. This will only increase future possibilities and hopefully it will keep expanding to unknown horizons.

1. USEFUL: Among the many useful items in the Thingiverse archives, one tool seemed to rise above the rest. That is, the Car Safety Hammer. In my many hours of watching the Discovery Channel show Mythbusters, I came across an episode attempting to quell myths of car crashes. This episode included cars submerged in water and, through a few experiments, Adam and Jamie discovered that a Car Safety Hammer was the best way to escape from a submerged car before drowning.


2. ARTISTIC/BEAUTIFUL: I have never seen a heart with such unique gears as those in the Keyed Heart Gear Keychain. I wondered how the object actually functioned and found this YouTube video. The way the gears all disassemble and eventually return to the original positions is fascinating and holds a sort of artistic beauty in my mind.


3. POINTLESS/USELESS: Although it could be a great party costume, the Mustache and Monocle on a Thin Stick has no true value.


4. FUNNY: Introcuing the IBITE iPhone 3 Hat Clip! To be honest, the idea of a hands-free iPhone holder is interesting, but lets be real: the picture is hilarious.


5. WEIRD: I'm sure many people would enjoy this item, but for me the idea of opening my beer with a Brain Bottle Opener is just odd.
