This technology allows for the production of highly accurate parts with superior surface quality.  The envisionTEC SI 500 is a high-speed, liquid resin that produces flexible, high-impact-strength, and accurate parts with a wide processing latitude and excellent tolerance to a wide temperature and humidity range during and after build. This material is especially useful in functional applications where extreme flexibility and impact strength are critical requirements, e.g. automobile panels, electronic enclosures, medical products, snap-fit parts, packaging, and plastic bottles.
