A.W.Bell's 3 Thermojet object printers use a jetting process that builds up a wax-like polymer layer by layer. Next step>

The first layer is sprayed directly onto a platen by a row of presicely controlled jets that can produce points 0.08mm square. This layer is then machined by a hot roller to a thickness of 0.08mm. The platen then drops and a new layer is jetted over the first. This process is repeated thousands of times to build a part. Print time is determined by model height. A model 254 x 192 x 200mm can be built in under 30hrs.

Parts with undercuts, overhangs and other complex features are no problem due to the automatic support structure demonstrated in the next animation.
