Demand grows for stereolithography materials
A growing demand for high-performance oxetane based materials, as well as for a growing line of composite resins include investment casting, fit and function and wind tunnel testing.
Rapid prototyping conferences scheduled in June
Conferences and expositions for European rapid prototyping industry: DSM Somos(R) will share its experience with European audience.
Somos 12920's properties make it ideal for tooling applications, as well as other applications which require a combination of stiffness and elevated temp- erature 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 12920 begins this month.

DSM Somos, leading technology innovators in the rapid prototyping (RP) materials industry, will be launching a new family of ProtoFunctional stereolithography resins at EuroMold in Frankfurt.
* 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.
Commercialization 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 molding.
Major applications for the material are expected in the transportation sector, where elastomeric parts are used extensively.
Somos ULM 17220 is now in beta testing.
* 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 behavior 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.

More information about DSM can be found at www.dsm.com * About DSM Somos materials - what is stereolithography? Stereolithography (SL) permits the rapid creation of 3D pieces utilising a computer-controlled laser that polymerizes light-sensitive resins.
The process is highly precise and constructs the object in a series of 'additive layers', providing the advantage of producing highly complex forms that are difficult or impossible to fabricate by machining or traditional molding techniques.
The evolution of advanced SL materials offers the potential of moving stereolithography from prototyping into production.
DSM Somos ProtoCompositesare resins reinforced with various materials, such as ceramics and glasses, to produce functional properties not possible using individual components.
DSM Somos ProtoComposite materials are a result of a significant research and development program investigating the potential for ACT-SL (Advanced Composite Technology for StereoLithography).
DSM Somos ProtoFunctional resins for stereolithography provide advanced technology to respond to the changing needs of new product development and industrial design.
In 2003, DSM Somos announced ProtoTool ceramic-filled resins, the first member belonging to the new ACTSL technology and the result of a significant research and development programme.
Traditional non-composite ProtoFunctional materials by DSM Somos satisfy a varying range of characteristics: transparency, superior humidity and heat resistance, and outstanding mechanical properties, replicating those of many production grade plastics such as polypropylene, polyethylene, ABS and PBT.
