3D Printing

HackRVA has several 3D printers in residence, described in the table below. In addition to traditional 3d printing, the Elegoo Mars Pro is a resin 3d printer that uses a liquid photopolymer that is selectively hardened by a UV LCD screen 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.
