ARCAM CAD-TO-METAL SYSTEM FROM STRATASYS PRODUCES LARGER PARTS

Stratasys today introduced in North America the Arcam A2 direct digital manufacturing and prototyping system, which allows the production of metal parts 75 percent larger than previous models. The A2 comes with two interchangeable build chambers. Users can choose between either a high or wide build chamber, depending on each part's requirements. The high build chamber measures 200 x 200 x 350 mm (7.87 x 7.87 x 13.78 in.). The wide chamber is cylindrically shaped with a diameter of 300 mm and height of 200 mm (11.81 x 7.87 in.). Improving electron-beam control, the A2 incorporates an all new high-voltage power supply, and it has an advanced heat model, which improves build speed, precision, and part accuracy. A new software version provides useful features such as automatic calibration, which eliminates potential for human error and results in optimal part accuracy. "This new generation of additive fabrication technology - the EBM process - is gaining acceptance worldwide," says Stratasys CEO Scott Crump. "And it has been catching on particularly well in the market for medical implant manufacturing." EBM systems are employed both for custom implants and for series production of standard implants, enhanced with new features that can be achieved only with direct digital manufacturing. "Producing solid metal parts ready for end use is changing the game for manufacturers," says Stratasys EBM channel manager Kirby Quirk. "With the addition of the new A2 to our portfolio of prototyping and direct digital manufacturing systems, we're giving companies the tools they require to stay competitive in an evolving manufacturing landscape." Materials offered for EBM systems include F-75 Cobalt Chrome; Ti6AI4V Titanium, the most widely used titanium alloy; and Ti6AI4V ELI Titanium, which features improved ductility and fracture resistance at low temperatures.
