M3D has commissioned the dream printer - a feature-packed, expandable, industrial 3D printer designed for manufacturing, assembly and design operations. Fully enclosed in a 20" all-metal frame, the 15.3"-cubed build volume makes printing just about anything possible. The Promega is reliable, fast and over-engineered to ensure high quality printing. Using open source software, firmware and hardware, this 3D printer has innovated its way through to being one of the largest open source printers available on the market.
