MINNEAPOLIS—(BUSINESS WIRE)—April 12, 2007— (NASDAQ: SSYS) 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, as well as 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
"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
"Producing solid metal parts ready for end use is changing the
game for manufacturers worldwide," 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
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
The Arcam A2 will be available for shipment in May.
Stratasys is the exclusive North American distributor for Arcam
EBM (Electron Beam Melting) systems.
EBM technology, patented by Arcam AB, produces solid metal parts
through a patented CAD to Metal(R) process. Parts are built in layers
of metal powder, each of which is melted by an electron beam to the
geometry defined by the CAD file. Because this process occurs in a
high vacuum, parts are completely solid, without imperfections caused
by oxidation. The time, cost and challenges of machining or investment
casting are eliminated, which makes alloy parts readily available for
functional testing or installation. EBM systems manufacture fully
dense parts from metal alloys 3-to-5 times faster than other metal
additive fabrication systems.
The EBM process is ideal for applications where high strength or
high temperatures are required. Medical product manufacturers can
benefit from the parts' high flexural strength for bone implants
requiring cycle life exceeding 10 million cycles (or movements).
Automobile makers can build strong parts for high temperature testing,
including under-the-hood applications. The aerospace industry can
benefit from the combination of a high strength yet lightweight metal
part. And because the EBM process produces a homogenous solid, parts
can be flight-certified.
Stratasys Inc., Minneapolis, makes rapid prototyping and direct
digital manufacturing systems. Stratasys equipment is used in
industries such as aerospace, automotive, defense, medical, and
consumer products. In 2005, the company installed 34 percent of all
systems sold worldwide, making it the unit market leader for the
fourth consecutive year, according to Wohlers Report 2006. Stratasys
patented the rapid prototyping process known as fused deposition
modeling (FDM(R)). The process creates prototypes or parts for end use
directly from any 3D CAD program using plastics, such as ABS,
polycarbonate, PPSF or other materials. The company holds 180 granted
or pending global prototyping patents. In addition to manufacturing
products, Stratasys is the exclusive North American distributor of
Arcam EBM systems that manufacture prototypes or parts from metal . On
