DSM Somos introduces new SL Materials for 2005

DSM Somos : 05 April, 2005  (New Product)
DSM Somos is pleased to introduce an exciting line-up of new
stereolithography (SL) materials for 2005.

Somos 12920 Precision HT: Elevating Aesthetics & Heat Resistance
Building on the success of Somos 12120, Somos 12920 Precision HT
delivers the look of production injection molding plastic with the highest
Heat Deflection Temperature (HDT) currently available in an un-reinforced,
commercial SL material.

Somos 12920's properties make it ideal for tooling applications, as well
as other applications which require a combination of stiffness and elevated
temperature performance. It offers excellent accuracy and water resistance
and, with an elongation at break of 4%, is similar to time-tested general purpose epoxy hybrid systems such as Somos 7120. Beta testing of Somos(R) 12920 begins this month.

Updated Somos HeCd Materials

This year, DSM Somos offers a collection of new resins optimised for use on
Helium Cadmium (HeCd) laser systems, with special attention given to part
aesthetics. Commercialisation of these materials is expected by mid-year:

Somos HeCd Flex is a general purpose material that mimics the properties
of polypropylene. It is ideal for applications where parts must bend
without breaking. Properties of HeCd Flex are similar to Somos 9110 with
the aesthetic updated to 'production plastic' white.

Somos HeCd Ultra GP mimics the behaviour of ABS and is an excellent choice
for creating products that need to look and act similarly to
production-grade thermoplastics. This resin is clear with a light,
glass-like green colour.

Somos HeCd Pattern HT is a high-temperature-resistant material with
inherent accuracy and water resistance. It is well suited for created
patters for tooling applications, as well as other applications which
require stiffness and elevated temperature properties.

Somos ULM 17220: Stretching SL Possibilities
First previewed in December 2004 at the Euromold conference in Frankfurt,
Germany, Somos ULM 17220 (Ultra Low Modulus) is a highly elastomeric
material ideal for the prototyping of rubber-like parts.

With a Shore A of approximately 70 and tensile elongation over 100%, ULM
17220 brings the benefits of stereolithography to applications traditionally
reserved for laser sintering (SLS) or silicone moulding. Major applications
for the material are expected in the transportation sector, where
elastomeric parts are used extensively. Somos ULM 17220 is now in beta

Somos FR 16120: First Fire Retardant Material Expands SL Market Potential
This year, Somos introduces the industry's first fire-retardant SL material
for use in general purpose applications. Somos FR 16120 carries a UL 94
V-0 rating, which describes self-extinguishing material behaviour in
small-scale laboratory tests. It is a common flammability standard for
plastic production parts.

Properties of Somos FR 16120 are similar to 94 V-0 rated polyurethane
structural foam systems currently used for production parts in business and
medical equipment housings, lawn and garden, transportation and electrical
housings. The material has been developed for both prototyping and rapid
manufacturing use and its general purpose properties allow it to be used
easily in a variety of applications. Beta testing of Somos FR 16120
begins this month.
