DSM SOMOS® CONTINUES TO AVOID USE OF CRYSTALLINE MATERIALS IN REINFORCED SL PRODUCTS DUE TO POTENTIAL HEALTH HAZARDS
18 August 2004 - DSM Somos
| DSM Somos has announced that it will continue to avoid the use of crystalline silica materials in the formulation of its ProtoComposite® reinforced stereolithography (SL) resins due to the potential health hazards these (crystalline) materials present as airborne particulates.

'Crystalline materials are commonly used as fillers and reinforcements but some are known carcinogens, or silicosis agents, when airborne,' states DSM Somos Research and Development Manager Dr. Gordon Smith. 'Because stereolithography parts often require secondary operations that may include sanding or grinding (resulting in airborne particulate), this presents a potential health hazard to users.' For this reason, DSM Somos has avoided the use of crystalline materials in the formulation of its both its ProtoTool 20L™ and NanoForm™ reinforced SL resins. Says Smith, 'While formulating with alternative filler materials adds to our product development costs, this approach is consistent with DSM's global concern for safety, health and the environment and, we believe, is in the best interest of SL users. We're confident that as the stereolithography industry becomes more familiar with the potential dangers of certain filler and reinforcement options, more emphasis will be placed on user-friendly and environmentally-responsible alternatives.'
