Biography[edit]

AbigailDeWeese.jpg

My name is Abigail DeWeese and I am a Junior at Principia College. I'm double majoring in Political Science and Global Studies with a minor in History. Originally, I'm from Dallas, TX where I discovered my love of BBQ and country music like a true southerner. While at school, I enjoy painting, running, and planning the upcoming Public Affairs Conference. I signed up for 3D Printing because traditional forms of science classes are not my expertise and it sounded interesting. My printer has yet to fully work, but I'm excited to eventually print something successfully.

Reflection on Open Source Movement[edit]

Truthfully,I don't know much regarding the Open Source Movement, but I believe that it's a movement that advocates open access to code so that everyone has the opportunity to utilize and or improve upon it. Personally, I find their dedication to widespread knowledge attractive and admirable. This was incredibly helpful while building my Jellybox printer because there were a few times I did not have the necessary part (I have an older model) and I was able to download and print the part because someone had made it available. In the future, I believe it'd be very helpful if other spheres of knowledge followed the philosophy of the open source movement. There is a lot that could be solved or education to be shared if more people simply had access to the information.

Demo stuff[edit]

My First Print First print.jpg
Preliminary Print The first print.jpg I checked in Cura if the print needed to be re-oriented, but it fit the bed without any changes. I brought the print speed down just slightly to 90 to ensure that the filament wouldn't be printed too quickly and disrupt the overall product. The print temp was set at 210. I didn't want to fiddle around with the temperature and risk something because the printer's had enough problems and I didn't want to make a gamble. It seemed to print fine without any form of adhesion. In my brief experience, it seems that it's best to add adhesion when the print is going to be larger along the Z axis (it'll be tall) in comparison to the other axis. This particular model didn't have a lot of detail, so it didn't seem necessary to make the layers small and very fine. There was one small hiccup. For the first few layers it printed normally and then it shifted one layer, but then it started printing normally again. I'm still working on what exactly could be the cause of that. I didn't think I needed to print multiple shells or need infill. The fan speed I kept the same as I normally do. Overall, it's a significant improvement from the first few attempts at printing.

Spare part Spare part.jpg Here's the spare feeder yolk I printed.
Blender project Final pyramid.jpg I used blender to design and create this object. I sliced it in Cura and reduced it to 4000 from it's origical size and added a skirt so it wouldn't come up off the plate.
FreeCAD project Bench.jpg I used FreeCAD to design this object. I didn't have to change the size before I sliced it, but I did add a brim and supports. There's some tape that wouldn't come off from when I had to tape it down, but it looks good other than that.
Penny trap project Mypennytrap.jpg We used OpenSCAD in class to design this. The only thing I added in Cura was a brim to keep it on the bed. That little blip in the middle is from when I paused it to put the penny in.
OpenSCAD project OpenSCADproj.JPG I downloaded the file from Thingiverse and adjusted some dimensions. In terms of slicing, I'll probably have to resize it some and add adhesion. The license for the file from Thingiverse is the Creative Commons Attribution.
OpenSCAD customizeable project BATMAN.png I downloaded the file from Thingiverse and added customizeable features for the user to edit. Here's the link for my project: https://www.thingiverse.com/thing:3907444. Here's the link for the original: https://www.thingiverse.com/thing:12381.
Science Equipment project Water trawl.jpeg I made this plankton sample collector for Dr. Farson. She'll be using it in her Oceanography class next semester. A commercially made model like this would normally cost $135+. One would have to provide their own weights, flotation devices, and net. NIH 3D link: https://3dprint.nih.gov/discover/3dpx-012370
