Multi-material 3D printer.What appears to be a first in 3D printer technology for rapid prototyping Building a part one layer at a time using a method of additive fabrication such as 3D printing. Such parts are used for concept modeling to determine if the product design meets the customer's expectations. is the ability to fabricate parts and assemblies made of multiple materials--such as hard and soft resins--in a single build cycle, which eliminates the need to glue together separate parts. Developed by Objet Geometries in Israel I U.S. office in Billerica, Mass.), the PolyJet Matrix Technology was introduced at the K 2007 show in Germany. It saves time in constructing multi-material prototypes, which can prevent expensive errors in designing complex molds for multi-material injection molding injection molding n. A manufacturing process for forming objects, as of plastic or metal, by heating the molding material to a fluid state and injecting it into a mold. . The technology works by jetting two distinct Objet FullCure photopolymer A photopolymer is a polymer which is cured by exposure to light, often in the ultraviolet spectrum. These polymers are useful in dentistry for fillings and in rapid prototyping in the stereolithography and PolyJet processes. materials in preset preset Cardiac pacing A parameter of a pacemaker that is programmed permanently when manufactured combinations. It controls every nozzle An orifice in an inkjet print head through which ink is sprayed onto the paper. Print heads with six thousand or more nozzles are common in today's printers. Nozzle in each print head, enabling combinations of model materials to be jetted from designated nozzles according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. location and model type. It is thereby possible to produce models where one material is partly or fully encapsulated by another material. Moreover, the technology allows for the creation of new combined materials by simultaneously jetting two photopolymers to produce an alloy with mechanical properties different from either of the "parent" materials. The first PolyJet Matrix-based 3D printing system is the Connex 500 model, said to provide smooth surface finish and fine details in all dimensions. It can print 600 x 900 dpi with a tolerance of 0.3 mm over large models. It builds in three modes, which deposit layers of 16 or 30 micron thickness at speeds from 12 to 20 ram/hr. Users can select material, printing speed and resolution and easily switch between different modes. (877) 48--9449 * www.2objet.com [ILLUSTRATION OMITTED] |
