Process description
material jetting is an advanced extension of ink jet tech that 2d printers use. a print head deposits a small amount of uv curable polymer onto the print surface, and almost instantly cured using an appropriate light source. each layer is printed directly on top of the last until the final part is complete.
strengths
- resolution: the high precision print heads allow for very fine detail
- easy multi material printing
weaknesses
- supports are required for overhangs
- post processing. parts often require a second cure in order to solidify them
- limited materials: as of now MJ printing is limited to waxes and photopolymers
Technologies
There are a number of specific technologies that can vastly change to capabilities of a printer.
