We are currently running two additive-later manufacturing machines in our labs:
Dimension Elite Fused-Deposition Printer - Parts are generated by extruding a thin filament of ABS plastic (material datasheet) to create successive layers either 0.007" or 0.010" thick. The maximum build volume is 8" x 8" x 12", and printing costs $10 per cubic inch of both model and support material.
Objet30 Photopolymer Printer - Parts are created from a photopolymer (material datasheet - see VeroGray) in layers only 28 microns (0.0011") thick. The maximum build volume is 11.5" x 7.5" x 5.75", and printing costs $0.60 per gram of both model and support material.
To have a part printed on one of these machines, the first step is to create an STL file of your model.
Once you have your STL file, you can send your job into the print queue by following these instructions.
