About Me
Below you'll find a brief bio about my history and current activities, as well as my contact information.
Bio
Herschel Pangborn is a senior at Penn State majoring in Mechanical Engineering as a member of the Schreyer Honors College, with a certificate in International Engineering and minor in Music Performance. He also holds a third degree black belt and instructs both youths and adults as a member of the World Tang Soo Do Association.
ENGINEERING: Herschel's study of engineering at Penn State has allowed him to visit and take classes in both China and Singapore. He currently works as an undergraduate researcher for the Penn State Applied Research Lab on EOD (explosive ordinance disposal) ground robots as a member of Dr. Sean Brennan's research group.
MUSIC: In 2008, Herschel attended the Pennsylvania Governor's School for the Arts as a saxophonist. He was a member of the PMEA District 6 Jazz Band on saxophone and a PMEA All-State clarinetist. In May of 2009, Herschel competed with the SCAHS Jazz Band in the Essentially Ellington Program hosted by Jazz at Lincoln Center. That summer, he spent several weeks touring European jazz festivals with the same group. Herschel is a member of the Penn State Centre Dimensions Jazz Band and a participant in the Penn State Jazz Combos. He has studied with Steve Bowman and Rick Hirsch, and is currently studying saxophone with David Stambler and clarinet with Smith Toulson.

Go to thingiverse.com. Use any means you like to look through the objects submitted to thingiverse and pick out 5 designs which you consider to be the most:
1. Useful
2. Artistic/beautiful
3. Pointless/useless
4. Funny
5. Weird.
Link to the 5 objects you’ve chosen, and discuss why you consider them well described by the 5 adjectives above.
Response
Useful
Bag Holder
I think that one of the great motivations for personal 3D printing lies in creating those little bits and pieces that make someone's day just a little bit easier. This device is so simple, but it would be harder to make by other processes or out of other materials. It's something we all wish we had in hand for our next trip to the grocery store.
Artistic/Beautiful
Vase
This user has posted a bunch of very cool and beautiful designs. This one reminds me of the intricate wares that can be purchased from glass blowers at art shows, except you don't have to worry about it getting shattered on the way home.
Pointless/Useless
Gasket for Model T Ford
I suppose this would save a machinist somewhere a lot of time, but I'm not sure how well a plastic gasket would hold up in an engine... even if it was a really old engine!
Funny
I'm torn between two things, so I'll just post them both.
Compost Toilet
Aren't there laws against this kind of thing?
Adimiral Ackbar
Don't try to print this... it's a trap!
Weird
Brine Shrimp Hatchery
There seems to be a lot of interest in this, so maybe I shouldn't be one to judge. However, learning 3D printing has definitely not made me think: "Awesome! Now I can finally make that brine shrimp hatchery I've always needed!"

Prompt
Read http://reprap.org/wiki/BackgroundPage. This should give you some feel for where Adrian Bowyer was coming from when he started the RepRap project. Respond to the following:
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?
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.
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.
Response
1. I believe that a self-replicating universal constructor could be feasible, but that it would ultimately require a complexity which may result in its bringing diminishing returns when being developed from machines that fall short of both self-copying and self-assembling features. Bowyer compares the four possible combinations of self-copying and self-assembling machines to rocks, proteins, viruses, and humans. The differences between each of these items are tremendously vast--they are essentially four data points in the spectrum between inanimate objects and intelligent life. I think that as replicating prototype technology expands, we may find that it is simply not worth trying to build a device that can make ALL of its parts. We may have so much easier a time building a "protein" than a "human" that we're happy to stick with proteins and bridge the gap through manual assembly. We might also find that it is much more sensible in the long run to divide the processes of copying and assembling into sub-functions that are completed by different machines. One machine might specialize in printing metal components, while another does plastics. A third might be dextrous enough to assemble these together. Working in consort, these machines form a self-replicating constructor system. Whether they are split amongst different devices or not, to achieve the goal of self-replicating, we need to develop processes for completing all these sub-functions. Right now, we are making strides in printing with plastics. However, the creation of intricate items made out of steel, for instance, remains largely a task of industry. Similarly, the microscopic circuit boards found in modern computing devices cannot yet be produced in one's home.
2. Wealth without money refers to the ability to produce an abundance of valuable resources without needing to purchase them through market purchases. Specifically, Bowyer discusses having people use their rapid prototypers to print all the items that they need in life instead of having to buy them. Users may even be able to produce or recycle their own raw materials for these printers. This suggests that, assuming it lies within the bounds of their printing capabilities, any person could have any item at his or her disposal for free, largely undercutting the theories of supply and demand. A system such as this would require the free sharing of information in the form of instructions on how to print a particular item. It also would require people to develop these items out of their own desire to help humanity. History has demonstrated that this can occur in some cases, as with the development of open source operating systems, however it is also likely that we would not have a device as amazing as the iPhone if massive teams of engineers and designers were not rewarded monetarily for their cooperation in producing such an item. In other words, there may be some tradeoffs associated with eliminating the driving force of market competition.
3. RepRap technology is currently primarily a hobbyist's task--not a consumer's. While a hobbyist is willing (and expecting) to tinker around with his work and employ "duct tape" style solutions throughout the process, the consumer expects everything to function out of the box as intuitively and effectively as possible. I think that RepRaps will branch out into this field if they are to become popularized. Printers will become easier to build as people learn to develop systems that are better described by "some assembly required" than by "a great deal of tinkering required." Similarly, the design, modification, and production of parts will become easier so that the system becomes less specialized. It used to take a special operator to send a message using morse code, yet now anyone can pick up a phone and dial a friend. This parallels the scenario that I envision for the future of RepRaps.
