See Paul Carlson from Dimension Inc. — a business unit of Stratasys — explain how the company’s 3D printers work. Dimension machines target office use and thus run quietly and without fumes. The 3D printers use what’s called fused deposition modeling. Basically, the machines feed ABS plastic in filament form into the head, which heats the material and then extrudes the plastic layer-by-layer, building the model from the ground up. Carlson also explains when color can be matched exactly, and shows examples of built parts. Finally, he explains the different support materials. The video runs about 3 ½ min. www.dimension.com
