The Envisiontec Mini is able to print very small items with resolution as small as 15 microns. Designed for the jewelry and dental industry. We use it to  print microfluidic channels, and other small parts for our pediatric projects. We have several resins in stock: transparent, flexible, and tough. I'm pleased to run a job for you, or teach you how to use the machine.  For larger jobs, I only ask that you reimburse us to replenish the resin. for more info, see: www.envisiontec.com
