Video Case Studies Quote

EnvisionTEC’s Perfactory 4 Digital Shell Printer (DSP) XL can be used for large scale production due to its large build area and high resolution. Fitted with the Enhanced Resolution Module (ERM), resolutions down to 50 µm (0.0020 in.) in the X and Y are possible. The micro mechanics can achieve as little as 15 µm (0.0006 in.) in Z (material dependent), making it one of the highest resolution systems in the industry. This accuracy does not come at the sacrifice of speed. The P4 DSP XL can build a tray of hearing aid shells in 2-3 hours (1-2 with the optional high speed module) as the DLP process cures all parts simultaneously. The resolution is transferred into the highest quality surface finishes achievable by any rapid manufacturing process. This is just one of the reasons this machine is a firm customer favorite with leading hearing aid manufacturers.
