The Perfactory Vida Hi-Res DSP (Digital Shell Printer) is a low cost, high resolution, easy to maintain and user friendly 3D printer for the production of high quality hearing aid shells and molds. The Vida Hi-Res DSP boasts a high resolution projector running at 1920 x 1080 pixel resolution with custom UV optics. Once the print job is preprocessed on a computer housing the Perfactory software suite, it is transferred to the machine via Ethernet or USB and can run independently without the need for continuous connection to the preprocessing computer. The surface quality of the printed models allows for production with no signs of stairstepping, unlike the visibility when using competing technologies. The 50 μm resolution of the Perfactory Vida Hi-Res DSP allows for the highest quality surface finishes achievable by any rapid manufacturing process.
