Howdy Doody, Appropedia folks. My name is Samuel Keller, but you can call me Sammy. I am a Political Science and Global Studies major at Principia College. I am currently taking ENGR 242 (3D Printing Technologies). I'll be honest, I'm mainly taking the class because it fulfills a General Education requirement (my college is a liberal arts school). However, I have come to really enjoy 3D printing and I'm saying that after just finishing the build of my Jellybox 1.3. It was incredibly frustrating, but the first print did feel very satisfying.

Our professor, Dr. Marie Farson, introduced us to the world of the Open Source movement. Open Source means that everybody has free access to the project. Everybody has free access to the product, but people can also make changes, improvements, and modifications to the source and make that available to the public as well. I think that's really cool. Something like 3D printing technologies is something that is maybe not as widely spoken about because it seems to fairly complicated. Well, it is, but anybody can learn it. I have no experience in Engineering, I study Politics and I was able to do it. My only prior experience is that I played with Legos growing up. By making the products publicly available for free, it incentives people to give it a try because the investments in this technology are fairly low.

Stuff in length
Now that we learned the basics of the various programs, we were tasked to design a piece of science equipment for one of the science professors at our college. I got in touch with one of our Biology professors, Chrissy, and asked her if she needed something. She asked me to design an adaptor for one of her test tube cold blocks. She was having trouble with it. The holes on the cold block were too big and wouldn't hold the tubes properly in place. The adaptor that I designed is just put over the actual holes and adds a thin layer (2 mm) so that the tubes still sit in the cold block. I had six prints total, including the prototype. Given that this is 3D printed and can be modified, it meant that the professor didn't have to buy a new cold block, which would have cost her upwards of $100. Instead, this was less than $1 worth of filament (not including time for designing it).

My pill holder has a production cost of roughly $2.5 (65 grams total at roughly 4ct/gram), so you save roughly 60% of the cost.

Introduction

MyFace.JPG


Howdy Doody, Appropedia folks. My name is Samuel Keller, but you can call me Sammy. I am a Political Science and Global Studies major at Principia College. I am currently taking ENGR 242 (3D Printing Technologies). I'll be honest, I'm mainly taking the class because it fulfills a General Education requirement (my college is a liberal arts school). However, I have come to really enjoy 3D printing and I'm saying that after just finishing the build of my Jellybox 1.3. It was incredibly frustrating, but the first print did feel very satisfying. Our professor, Dr. Marie Farson, introduced us to the world of the Open Source movement. Open Source means that everybody has free access to the project. Everybody has free access to the product, but people can also make changes, improvements, and modifications to the source and make that available to the public as well. I think that's really cool. Something like 3D printing technologies is something that is maybe not as widely spoken about because it seems to fairly complicated. Well, it is, but anybody can learn it. I have no experience in Engineering, I study Politics and I was able to do it. My only prior experience is that I played with Legos growing up. By making the products publicly available for free, it incentives people to give it a try because the investments in this technology are fairly low. Just because it is Open Sources does not mean that you can't make money from it. One of the creators of Jellybox made money by selling 3D printed replacement parts for the printer. Since we use the Jellybox model, we thereby participated in the Open Source movement. Yeehaw! Like I said previously, I've come to enjoy 3D printing and I'm kind of fascinated with how the printer works. I'm still learning to understand more about it, but I think I can see myself keeping it up in the future as a hobby.
