Would any Somos* for SLA users care to comment on their experience with these
new materials? Please compare and contrast it to the other resin(s) that you
have been, or still are using.

<< DuPont Introduces Somos(R) 7120 Epoxy Resin for Solid State Laser
Systems
WILMINGTON, Del., Aug. 5 /PRNewswire/ -- The DuPont Company (NYSE:
DD) today announced the availability of Somos(R) 7120, the second
member of the new "Somos" 7100 series of epoxy resins. Created for
solid state laser equipment such as 3D Systems SLA-350, EOS STEREOS MAX
400, EOS STEREOS MAX 600, and Aaroflex Solid Imager, "Somos" 7120 is
now commercially available in North America. "Somos" 7120 shares
properties similar to "Somos" 7100, with a high heat deflection
temperature, water resistant parts, virtually no bubbles, and faster
photospeeds.
The new "Somos" 7120 resin has excellent green strength and a wide
process latitude, which allows the use of both ACES and WEAVE style
build parameters. The variety of build styles available lets users
choose the optimum style for their business needs.
According to Michelle Paetz, Technical Marketing Engineer for DuPont
"Somos" Solid Imaging Materials, "Initial customer comments about
`Somos' 7120 have been very positive. The 7100 Series of resins will
revolutionize the current standards for build performance and part
quality. In the 7100 Series, resin properties have been dramatically
improved, allowing customers to experiment with applications previously
considered impossible." Incentives up to 80 percent off the initial
fill are currently being offered to customers who upgrade to the new
material before September 15.
"Somos" 7120 provides users with excellent down-facing surfaces. Fewer
structural supports are required, and thinner undistorted walls are
possible. Suresh Jayanthi, DuPont Senior Research Engineer, feels that
most of these features can be attributed to DuPont's chemical research
and development efforts to optimize the resin's viscosity. "Not only
has our customers' product quality increased with `Somos' 7120, but
their productivity has been further enhanced by the faster photospeeds
and shorter delays compared to current competitive epoxies," he said.
DuPont invented photopolymers more than 50 years ago, and was a pioneer
in the development of stereolithography equipment. Today, DuPont uses
its experience with stereolithography equipment to optimize the
capabilities of its resins. "We offer the world's widest selection of
solid imaging materials, and the ability to expertly optimize resins to
available laser systems," Paetz said. DuPont also works closely with
original equipment manufacturers and leading rapid prototyping users to
thoroughly test materials before they are released to market.
DuPont "Somos" resins for stereolithography have been optimized for
Argon-ion, Helium-Cadmium, and solid state UV laser systems, and range
from the only available flexible resins ("Somos" 2100 Series), to
general purpose highly transparent acrylate resins ("Somos" 3100
Series), second generation epoxy resins ("Somos" 6100 Series), and a
third generation of epoxy resins ("Somos" 7100 Series). DuPont also
provides powders for selective laser sintering, such as the flexible
elastomer powder, "Somos" 201, now available from DTM Corporation.
