In December 2007, Objet Geometries announced its new PolyJet Matrix technology for creating rapid prototype models using multiple materials. The technology and the Connex500 RP system that uses it made its U.S. debut on the show floor at SolidWorks World 2008.
The system is yet another leap forward for the rapid prototyping industry by enabling the simultaneous jetting of multiple model materials in a single build process.
The system provides 600 x 600 dpi models in both the x and y axes, with model walls as little as 0.6mm. The company claims the highly precise printing delivers 0.3-mm tolerance across large models. There are up to 21 materials to choose from that deliver such features as translucent parts, the ability to coat parts for a rubber-like appearance and parts with combined rigid body and flexible material.
The machine is 55 x 44 inches wide and 44 inches high.
Siemens and Fraunhofer Institute for Laser Technology have achieved a faster production process based on selective laser melting for speeding up the prototyping of big, complex metal parts in gas turbine engines.
