3D printing was used extensively in my final project. Many of the components in my project (buttons, lego plates) were 3D printed.
After spending many hours repairing our Ultimaker 2 in the LLK space and getting failed prints on the Ultimaker 2+ machines in the CBA shop. I decided to use my own personal Printrbot Simple Metal. It prints 1.75mm filament with a possible resolution of 100 microns. I have been using the printer for over 2 years without any major issues. At one point during the semester, my printer ran for almost 72 hours straight printed components for my final project.
