The XFAB Expands the Material Portfolio of Stereolithography 3D Printers

At CES, we were treated to a number of desktop stereolithography machines. Among them was DWS Lab, an Italian spin-off company that had brought its own XFAB. While the XFAB didn’t promise higher resolution, it did offer a range of materials much wider than any of its competitors.

Matteo Fio, a marketing assistant for the company, explained that DWS Lab was the recently formed consumer division of DWS Systems. The DigitalWax Stereolithography process projects a solid state blue laser at a mirror, so the laser itself sits still while the mirror rotates to direct the light through a transparent vat of resin to cure a three dimensional object. Previously, DWS sold industrial machines for the jewellery and dental industries, among others. The XFAB would be the consumer version, to be released sometime this Spring for around $5k.

Unlike its competitors, the XFAB leverages the industrial experience of DWS to print in a diverse set of materials: acrylate resin, rigid opaque, transparent, as well as ABS, polypropylene, rubber and ceramic mimics. Matteo described the ceramic as a composite material with nano-sized bits of ceramic throughout with a light blue colour. The print area is 180 x 180 mm, about 7” x 7”, and the machine can achieve layer thicknesses of between 10 and 100 microns, with detail resolution of about 80 microns. The company also has plans to release an XFAB Mini in the summer with a price point of about $2,500 that will utilize the same technology at a smaller scale. … (Read more)
