NEXT GENERATION URETHANE MATERIAL FOR FIRE RETARDANT APPLICATIONS OFFERED BY SOLID CONCEPTS INC

VALENCIA, California - July 19, 2007

VALENCIA, CA – Solid Concepts Inc. has introduced a new cast urethane material offering FAR 25.853 Fire Retardant Certification and excellent mechanical properties to its’ QuantumCast cast urethanes materials offering. AFP-3100FR is a new polymer utilized with Solid Concepts’ QuantumCast™ process, where Advanced Formula Polymers (AFP) are cast in a proprietary rapid tooling technology that offers mechanical properties closely resembling engineered plastics. The resulting castings are void-free, durable, color-matched pieces produced quickly without hard tooling. AFP-3100FR meets FAR 25.853 Fire Retardant Certification requirements and is amongst the toughest material in its class with a 2.10 ft-lb/in Izod Impact Strength (method A, notched) rating. This material is rigid, 424,000 psi flexural modulus (ASTM D790), and heat resistant with a heat deflection temperature of 179° F at 66 psi (ASTM D648). Additionally, Solid Concepts offers Micro-welded inserts - the strongest inserts available in the industry and a variety of AFP’s with up four times the impact strength of older urethanes.

• SolidView
  SolidView® software allows you to view, rotate, measure and communicate design intent with non-CAD users—starting with our free 3D CAD viewer—SolidView/Lite.
• SLA & PolyJet
  SLA® & PolyJet™ provide accurate concept models and master patterns in record time. Complete in-house finishing capability for production-like prototypes.
• SLS
  SLS® (selective laser sintering) produces rugged Nylon 11 and Nylon 12 prototype and production parts and is ideally suited for Direct Digital Manufacturing.
• FDM
  FDM (fused deposition modeling) produces both prototype and production parts from ABS plastic, polycarbonate, and Ultem materials.
• CNC
  CNC prototypes, parts and master patterns are ideal in applications where the material property or size requirements make other prototyping techniques unsuitable.
• Cast Urethane
  Cast Urethane (a proprietary advanced casting technology and advanced formula polymers) produce strong pre-production and short-run production components.
• Composites
  Composites (fiber reinforced plastic) technology produces large, rigid, accurate panels with excellent strength-to-weight ratio and surface finish. Chose between CompositeCast™, Hand Lay-up FPR and VARTM.
• Tooling
  Tooling from Solid Concepts provides quick-turn tooling options for Chinese tooling & production, export tooling from China, and domestic tooling, all with domestic project management.
• Molding
  Injection Molding from Solid Concepts brings you the best of both worlds by providing Chinese pricing and lead times along with Solid Concepts quality and domestic project management.
