Printer Overview

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

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.

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.

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.

Desktop FDM Machines – Parts are generated by extruding a thin filament of various materials to create successive layers between 0.1 and  0.4 mm thick. The maximum build volume is 11″ x 11″ x 11″, and printing costs $2 per cubic inch of material. We have a selection of different desktop machines including the Lulzbot Taz Pro, Prusa i3 MK3S, Lulzbot Taz Workhorse, Lulzbot Taz Mini 2, Lulzbot Taz 5, MakerBot Replicator+ 5th Generation, and MakerBot Replicator 2. Materials can include PLA, ABS, NinjaFlex, PVA, PETG, and others. Our machines are typically using black material though we often have other colors available. You may also choose to provide your own material. If you bring your own material there is no cost to print. Print operators will select the machine that’s the best fit for your request.
