Process description
material jetting is an advanced extension of ink jet tech that 2d printers use. a print head deposits a small amount of material 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
- 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
- slow print times
| Low | High | |
|---|---|---|
| volume X/Y/Z (mm) | 200/100/40 | 1450/1110/1800 |
| resolution (mm) | .025 | |
| layer height (um) | 10 | 50 |

NPJ: created by XJet nano particle jetting involves suspending metal or ceramic particles into a suspension material. after printing the part is put through a sintering step leaving a metal or ceramic part.
SPD: supersonic particle deposition also known as cold spraying is a prosses where metal particles are accelerated to a speed where they will bind to each other.
GDP: gel dispensing printing created by Massivit is a process of material jetting that uses a uv resin gel
