Use the following guidelines when preparing your files for 3D printing:
1. All models should be converted to editable format and welded together by material type.
2. Separate materials should have mating surfaces, that is touching without overlap.
3. Use inches as measurement system and double check part size to be around 6x6x6 inches or less.
4. Be sure there are no overlapping or hollow parts. All parts need to be water tight.
5. When subtracting or combining parts together, consider using a package such as Rhinoceros for Windows or the beta version for OS X. (Available on Travis’ laptop during class times).
6. Final models should be in STL format. One file for each separate material type.
7. Create a render of your model that resembles the final product for reference when assembling builds.
8. Use no more than 2 materials total in your model.
