Through continuous interaction with our customers, pattern makers and foundries, DSM Additive Manufacturing has developed Somos® Element as the next generation of stereolithography resins specifically designed for producing investment casting patterns. Somos® Element is an antimony-free stereolithography material that has been specifically created to improve the repeatability and quality of 3D printed casting patterns. Patterns created with Somos® Element have strong green strength, are dimensionally stable during storage and leave a minimal amount of ash residue after burnout. Any residue that is left behind is easily removed, leaving a perfectly clean void in the ceramic mold. This translates into less mold prep and lower rates of rework saving customers time and money.
