3D Printing
HackRVA has four 3D printers in residence: a Prusa i3 MK3, Prusa i3 MK3S+, Ultimaker 3 and an Elegoo Mars Pro. The Elegoo Mars Pro is a resin 3d printer that uses a liquid photopolymer that is selectively hardened by a UV laser on the bottom of a clear tank. HackRVA usually has a limited selection of Jessie (preferred brand) PETG and PLA for small occasional prints. Members should provide their own filament if they are printing a large project or require a specific type.
Here’s a short comparison of the four printers:
