ARRK Product Development Group Purchases Three DTM Sinterstation(R) 2500plus Systems

More Companies See Advantages of SLS(R) Process as They Fill Heightened Demand
                     For Durable, Rapidly Produced Parts

    AUSTIN, Texas, Feb. 6 DTM Corporation
announced today that ARRK Product Development Group, one of the world's
largest model maker and prototype manufacturer's in the world, has purchased
and installed three DTM Sinterstation(R) 2500plus systems at its facility in
Portland, Oregon, U.S.A.  ARRK serves the computer and electronics industry,
as well as large OEMs in the automotive and aerospace industries.  Its three
new Sinterstations will complement and add to its other rapid prototyping
capabilities.  (http://www.dtm-corp.com)
    "ARRK's recent Sinterstation purchases are but one example of a growing
trend in our industry.  Companies like ARRK, which previously relied on other
rapid prototyping solutions, are now seeing the advantages of using a system
such as ours, which offers more options and flexibility.  Our Sinterstation
allows companies like ARRK to better meet the needs of customers who want to
create highly durable parts quickly.  This allows them to test their new
products earlier in the development cycle and thus, move them to market
faster," says Kevin McAlea, Vice President of Marketing and Business
Development for DTM.
    A growing number of manufacturers and service bureaus all over the world
use DTM's Sinterstation systems to rapidly create three-dimensional
prototypes, parts, molds, tooling, and casting patterns directly from 3-D CAD
files.  With a Sinterstation, these companies can create parts in a matter of
hours using the SLS(R) process and a CO2 laser.  Here, the Sinterstation
creates the part by fusing together layers of powdered plastic, metal or
ceramic powders.  The result: a durable 3-D part.
    "Our customers have a growing need for rapidly-produced, plastic
prototypes that are realistic enough, durable enough, and close enough to
production parts to allow for accurate product testing.  In the past we've
tried to produce these prototype parts via CNC machining.  However, we have
found that using the Sinterstation allows us to economically and effectively
deliver these durable parts to our customers quickly and according to desired
specifications," says Tony Moran, U.S. Operations Vice President, ARRK Product
Development Group.
    DTM customers have reported that producing prototypes, parts, or tooling
with a Sinterstation and anyone of DTM's SLS materials can reduce project
turnaround time by weeks.  In addition, using the SLS process often saves
companies money.  Some Sinterstation users report that they have manufactured
parts in plastic for 80 to 90 percent less than it would cost to produce the
same parts in metal.
    Initially, ARRK plans to use DTM's popular DuraForm(TM) material, a
durable, versatile Nylon-based plastic.  "We also hope to work with some of
DTM's other materials.  We see the SLS technology as one that will give our
customers plenty of choices and flexibility," says Moran.
    Numerous service bureaus throughout the Americas, Europe, and Asia include
Sinterstation systems in their offerings.  They provide an excellent resource
for companies with a need for rapidly produced functional prototypes and
parts.
    "ARRK's purchase of three 2500plus Sinterstation systems, coupled with
their worldwide presence, will give more companies access to a wider range of
functional prototype and low volume manufacturing options," says DTM's McAlea.
    Among the more than 300 companies currently using Sinterstations are big-
name manufacturers such as Boeing, BMW, General Motors, Pitney Bowes, Rockwell
International, Volvo Penta, and others.  Parts and prototypes made on
Sinterstation systems also are used in non-industrial settings, such as
science and medicine.  For more information on DTM customers and SLS

    About DTM Corporation
    DTM develops, manufactures, and markets advanced rapid prototyping and
manufacturing systems, including the Sinterstation 2500plus.  All
Sinterstation systems utilize a process called SLS selective laser sintering
and any of several plastic or metal SLS materials to create 3-D objects from
Computer Aided Design (CAD) data.  Unlike competing technologies and systems
that are used primarily to create visualization models, DTM's systems address
industry's growing need for rapidly produced, durable, testable prototypes and
end-use parts.
