Liquid photopolymer is heated to achieve optimum viscosity.

The MJ print head then jets photopolymer onto the surface of a build like a 2D printer.

The jetted photopolymer is then cured by a UV light before the next layer is jetted on.

MJ can use multiple nozzles, so different colours or different materials can be jetted.

Support structures can be jetted in a dissolvable material to make post processing easier.
