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″. 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 in layers only 28 microns (0.0011″) thick. The maximum build volume is 11.5″ x 7.5″ x 5.75″. Material changes take time, users will be notified if this is necessary.

Connex 500 Photopolymer Printer – Parts are created from a photopolymer in layers 16 microns (0.0006″) thick. The maximum build volume is  500 mm x 400 mm x 200 mm (19.6″ x 15.75″ x 7.87″). The machine also allows for multiple materials within the same part, as well as blending materials to create specific discrete hardness values.

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″.

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″. We have a selection of different desktop machines including the Lulzbot Taz Pro, Prusa i3 MK3S, Lulzbot Taz Workhorse, Lulzbot Taz Mini 2, 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.

Desktop Stereolithography/Digital Light Processing (SLA/DLP) – Parts are built by using a laser to trace part layers in a photoreactive polymer vat, causing them to harden, The maximum build volume is 125 mm x 70 mm x 120 mm (4.92″x2.76″x4.72″). We have two different desktop machines, the FabPro 1000 and AnyCubic Photon S. You may choose to provide your own material for the AnyCubic Photon S, as the machine is open material capable. Print operators will select the machine that’s the best fit for your request unless otherwise specified.
