ACCELERATE AD&P; > March 2013 > ACCELERATE So they���ve developed what they���re describing as a ���wideformat printer,��� the Objet 1000. This system provides a build envelope of 39.3 �� 31.4 �� 19.6-in. Because this unit can print big parts, there are six resin cartridges with a total capacity of 108 kg. The Objet 1000 uses the company���s Connex multi-material build capability, which means that there are over 120 materials to select from (which simulate both standard and ABS-grade plastics); a single model can include up to 14 different materials. According to Ofer Nir, product manager for the system, it features an industrial-grade design with the intent of allowing users to run it 24/7. This high utilization, he says, can help accelerate the ROI for the equipment. Yes, it has a conveyor belt. voxeljet (voxeljet.com), a 3D printing systems and service provider, has developed what Dr. Ingo Ederer, company CEO, claims is ���the world���s ���rst continuous 3D printer,��� the VXC800. ���The building and unpacking process steps now run in parallel, without a need to interrupt the operations of the system,��� Ederer explains. DELTA�� protects surfaces. p The VXC800 from voxeljet is a continuous 3D printer, which is said to be bene���cial for producing molds and models for metal casting. PRODUCT QUALIT Y Superior Finish. With basecoats and topcoats that provide extremely effective surface protection for a variety of fastening needs. It starts in our labs and carries right through to our customer���s floor. Our team of coating experts works with OEMs, parts manufacturers and coaters worldwide to produce coatings that set new standards in fastener corrosion protection. From springs, brackets and clips to nuts, bolts and screws... we test our topcoats and basecoats under the most stringent standards to provide best-in-class performance in corrosion protection, consistent torque and tension values and resistance to chemical attack. Looking for that superior finish? Look to D��rken. Our coatings and finishing systems product line includes: DELTA-PROTEKT�� ��� inorganic coating systems DELTA��-TONE ��� non-electrolytic zinc flake basecoat system DELTA��-SEAL ��� topcoat systems for a variety of metals DELTACOLL�� ��� clear and black topcoats for zinc and zinc alloy electroplating www.doerkenusa.com 517.522.4600 From the start, it���s all about the ���nish. 46 That is, there is a horizontal belt cover that controls the layer building; layers are built at the entrance of the conveyor, and unpacking, or unloading, takes place at the exit. The machine works with layer thicknesses ranging from 150 to 400 ��m. The build envelope is 800 �� 500 mm in width and height, with the lengths of the molds produced limited primarily by the manageability of handling the part. The material powdered material that isn���t printed (i.e., is not attached by binder material) is returned straight to the build zone from the unload area.
