DSM Somos has announced the full commercialization of NanoForm™ 15120 after nearly one year of successful, comprehensive beta testing by a variety of industries and stereolithography (SL) service bureaus worldwide.

NanoForm 15120 is a composite stereolithography material which incorporates non-crystalline nano-particle technology for enhanced performance properties, including exceptionally high stiffness and heat resistance. Heat deflection temperatures of more than 500°F (265°C) have been reported.

"The composite technology of NanoForm contributes to exceptional dimensional stability, low shrink, and low coefficient of thermal linear expansion," says DSM Somos Application Development & Technical Service Manager Matt Cantwell. "This material offers a unique alternative to previous stereolithography and selective laser sintering solutions available on the market. It is processed in an identical manner to unreinforced liquid SL resins, requiring no mixing or other special handling."

NanoForm was first introduced at the Frankfurt Euromold fair in December 2003. "Since that time, numerous companies have been successfully implementing it into their material offerings for medical, automotive and aerospace applications," states DSM Somos Marketing and Sales Manager Ty Bacon.

Marc Lesko, Rapid Prototyping Product Designer for ConvaTec (leader in ostomy and wound care products) says, "I've successfully used the Nanoform resin to produce vacuum form molds and lab test fixtures. Its high temperature and hardness properties make it very useful for rapid prototyping and this resin has helped to speed the development process."

What is stereolithography?
Stereolithography (SL) permits the rapid creation of 3D pieces utilizing 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 ProtoComposites™ are 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 ACT-SL™ technology and the result of a significant research and development program. Traditional non-composite ProtoFunctional materials by DSM Somos satisfy a varying range of character-istics: transparency, superior humidity and heat resistance, and outstanding mechanical prop-erties, replicating those of many production grade plastics such as polypropylene, polyethylene, ABS and PBT.
