MINNEAPOLIS--(BUSINESS WIRE)--May 1, 2003--(Nasdaq:
Rapid-prototyping system maker, Stratasys announced that it has
released PPSF plastic for its FDM Titan rapid prototyping system.
Among rapid prototyping materials, PPSF (or polyphenylsulfone) has the
highest strength, heat resistance, and chemical resistance.
Aerospace, automotive, and medical product makers are among the
first users expected to take advantage of the material. The aerospace
industry will likely welcome the material's flammability properties;
automobile manufacturers are expected to take advantage of its
petroleum resistance and its ability to function at over 400 degrees
F; and medical-product makers will be interested in the ability to
sterilize PPSF prototypes.
Beta-test site, Parker Hannifin, installed a PPSF model onto an
automotive engine. The part, a filter called a crankcase vapor
coalescer, was mounted on a V8 engine and tested for 40 hours to
determine filter-medium efficiency. The part collected gasses
containing 160 degrees F oil, fuel, soot, and other combustion
by-products. Parker Hannifin's Russ Jensen said, "The assembly didn't
leak, and it appeared to have the same strength and properties as when
first assembled. We're pleased with its performance."
Beta-test site, MSOE (Milwaukee School of Engineering) operations
manager, Sheku Kamara, was likewise pleased with the new material.
"With a glass-transition temperature of 450 degrees F, PPSF has the
highest operating temperature and toughness of any rapid prototyping
material except metals," he said. "During tests of an adhesive, PPSF
prototype parts were exposed to temperatures from 14 degrees to 392
degrees F and maintained integrity."
PPSF was first previewed to the public at last year's Rapid
Prototyping & Manufacturing Show. PPSF prototypes can be seen at this
year's show in Chicago, May 13 - 15 at booth # 622. Titan users can
now model using ABS plastic, PPSF, and polycarbonate. Switching among
the materials is a simple step performed by the user. PPSF-ready
Titans began shipping in April. Existing Titan users wishing to
upgrade should contact their local Stratasys sales office for details.
FDM models will not warp, shrink, or absorb moisture. Like all
Stratasys equipment, the FDM Titan requires no special facilities or
venting and involves no hazardous materials or by-products. Stratasys
systems typically represent the lowest total cost of ownership among
the major rapid-prototyping suppliers.
Stratasys, Inc., Minneapolis, is the second largest manufacturer
of rapid prototyping systems. The company's patented fused deposition
modeling (FDM(R)) process creates solid models directly from 3D CAD
files using ABS plastic, polycarbonate, PPSF or other materials.
Stratasys provides rapid prototyping systems for OEMs such as
aerospace, automotive, defense, consumer, and medical product makers.
