C3-Rigid series is made up of fast-curing materials designed to simuulate standard rigid plastics including ABS, Polypropylene and other custom-engineered for specific mechanical properties. They are suitable for polyjet and SLA type printers. Printed materials exhibit high tensile strength and impact resistance in some cases exceeding the properties of the materials they emulate. Mechanical properties of printed samples remain steady for more than six months in ambient environments. The C3-Rigid series materials may also be formulated for specific end-use requirements including resistance to chemicals or low-extractability for medical devices.
