Project SummaryDue to recent leaps open source technology, 3-D printing is set to take off in the coming years. Current open source machines can perform a single process, (e.g. laser sintering, thermoplastic extrusion, routing) leading for the need to buy and maintain multiple machines in order to prototype complex parts. Multi-process 3-D printers are capable of performing these processes, minimizing capital and maintenance expenses, while simultaneously unlocking the ability to produce multiple substrate parts such a printed circuit boards or other composite materials. Current multi-process printers are not open sourced and have costs well above what the average hobbyist can afford.
The goal of the project is to demonstrate a multi-process 3-D printer that is both designed as open source and at an appropriate price range to be marketed to the average hobbyist. This printer will incorporate an interface capable of supporting multiple process heads, which could additive or subtractive in nature, that will operate with minimum setup or training. (i.e. Plug-and-Play) Open sourced or low cost software will be used to control the printer. This project will create a platform that can be expanded upon by future MSD teams.
