Z Corp. 3D Printer

A binder is printed onto successive layers of plaster powder. Once the part has been built it can then be infiltrated with either Cyanoacrylate (like Superglue) to give strength or epoxy resin. 

Positives: Very quick and cheap to use
Largest model size: 350 x 250 x 200 mm

SLA (Stereolithography Apparatus)

SLA works by selectively curing a photosensitive epoxy resin (either clear or white) with an ultra-violet laser – wherever the laser touches the surface of the resin, the resin turns from liquid to solid.

Positives: High definition and accuracy – parts are ideally suited to downstream applications such as silicone moulding
Largest model size: 250 x 250 x 250 mm

Objet™ 'Polymerjet' Resin Models

Positives: Very fine resolution in 12 micron layers, direct metal casting from the part with no intermediate steps needed.

MCor Paper Printer

 Uses glue to assemble A4 paper into successive layers, forming a solid 3D part. 

Positives: Low cost and environmentally friendly process
