One of the best rules in TARC is that students have to do all of the work. Does anyone know how this breaks down on 3-D printed parts? I would expect students would have to create the 3-D model, but do they have to load the 3-D printer and push the figurative green button? Could students make the 3-D model and send it out to a printing shop? My teams want to use some printed parts for next year and I want to make sure they're on the right side of the rules. Thanks!
