Functionality of 'Rubber-Like' Material Enhanced With New Infiltration Process

    AUSTIN, April 7 -- DTM Corporation announced
today the availability of a polymer infiltration material that allows
customers to quickly create functional, flexible prototypes such as tubing,
hoses, and gaskets from DSM Desotech's Somos(R) 201 material.
    DTM markets and distributes the Somos 201 powder, a thermoplastic
elastomer, which was developed by the Somos group for use in DTM's
Sinterstation systems.  Somos 201 laser-sintered parts infiltrated with the
new polymer material are watertight, exhibit greatly increased burst strength,
wear resistance, improved tear resistance, and enhanced surface finish.  The
infiltration material, available from DTM in late April, also allows customers
to make parts in any color.  (http://www.dtm-corp.com)
    "This new infiltration process expands the functional range of the Somos
201 parts, allowing them to be used in more demanding test environments,"
notes Kevin McAlea, DTM's Vice President of Marketing and Business
Development.  "The ability to rapidly create strong, watertight, flexible
prototypes will allow us to address applications where the final part would be
made from rubber or a thermoplastic elastomer.  Automotive hoses, gaskets, and
door seals are obvious examples."
    DTM Corporation develops, manufactures, and markets the Sinterstation
family of systems for applications in the growing rapid prototyping and
manufacturing marketplace.  These systems utilize SLS technology to create
three-dimensional objects directly from 3-D CAD files using a CO2 laser to
fuse plastic, metal and ceramic powders.
    DTM's products are sold, serviced, and supported directly through DTM in
North America, the United Kingdom, Germany, and Singapore and through
distributors worldwide.
    DSM Desotech is a world leader in the research and formulation of UV-
curable materials, including adhesives, lacquers, hard-coats, and inks and
coating for optical fiber.  DSM Desotech recently purchased DuPont's Somos(R)
solid imaging materials business.  (http://www.dsmsomos.com)
