The EnvisionTEC Perfactory Micro DSP is a professional desktop 3D printer made by EnvisionTEC, a German manufacturer.

EnvisionTEC’s Perfactory Micro Family are user friendly 3D printers for rapid prototyping and rapid manufacturing. Those professional 3D printers use a Direct Light Projection (DLP) technology from Texas Instruments to selectively photocure liquid resin, like in Stereolithography (SLA).

The EnvisionTEC Perfactory Micro DSP produces highly detailed physical 3D duplication of digital ear shells and molds. The EnvisionTEC Perfactory Micro DSP can produce 2-4 ear shells or ear molds per build in under two hours. This 3D printer is optimized to build in a choice of two most materials, opaque E-Shell 200 Pink for ear shells and transparent E-Shell 300 Clear for ear molds.
