If 2D printing inspires 3D printing 3D
Multi Jet 3D Printing is a method of additive manufacturing based on the same concept that 2D ink printing : the print head is moving to lay drops of photopolymers. UV light is than used to polymerize these drops. The platform goes down as the layers build up.
Multimaterial
The advantage Multi Jet 3D Printing is that it allows to print objects by laying down simultanously several rigid or flexible materials. It is thus possible to create parts which have been unfeasible until now by Laser Sintering or by Stereolithography :
Parts with overmoulding to prototype parts which will then be manufactured by dual-injection.
Covered parts: Covering/ embedding of a rigid material with a flexible material to give functionality to soft touch.
