Printer Overview

We are currently running four varieties of additive-layer manufacturing machines in our labs:

Image result for makerbot 2

 MakerBot 2 Fused-Deposition Printer – Parts are generated by extruding a thin filament of Polylactic Acid (PLA) to create successive layers 0.1, 0.2, or 0.3 mm thick. The maximum build volume is 11.2″ x 6″ x 6.1″, and printing costs $2 per cubic inch of material. Our machine is traditionally using black material.

ProJet 6000 Stereolithography Printer – Parts are built by using a laser to trace part layers in a photoreactive polymer vat, causing them to harden into 0.002″ or 0.004″ thick layers. The maximum build volume is 10″ x 10″ x 10″, and printing costs $20 per cubic inch of model material.

Objet30 Photopolymer Printer– Parts are created from a photopolymer (material datasheet – see VeroBlack) in layers only 28 microns (0.0011″) thick. The maximum build volume is 11.5″ x 7.5″ x 5.75″, and printing costs $0.62 per gram (or $12 per cubic inch) of model and support material. Material changes incur an additional $30 charge — users will be notified if this is necessary.

Fortus 450mc Fused-Deposition Printer– Parts are generated by extruding a thin filament of ABS, ASA, Nylon 12, or ULTEM to create successive layers ranging from 0.005″ to 0.013″ thick. The maximum build volume is 16″ x 14″ x 16″, and printing costs $12 per cubic inch of both model and support material. Our machine is traditionally set for 0.005″ in ASA. For any changes in material or resolution please allow for more lead time.
