Protomatix operates Dimension ® SST 768 series FDM machines from Stratasys. These machines have an 8" X 8" X 12" build envelope and a wash away support structure for fine detail features. Our FDM printer helps in many ways including fixturing, mold forming, and part visualization.
Machine shop
The Protomatix machine shop is well suited for small to medium size parts requiring precision tolerances. Often special fixturing is designed to accommodate part fabrication. Machines may be retrofitted for interface with electronic test equipment for electro-mechanical and electro-optical measurement and alignment. Precision measurement tools may be used for independent measurement or integrated into system measurement devices.
Electronics lab
Protomatix electronics lab consists of standard and specialty test equipment. Standard test equipment includes but not limited to precision digital multimeters, oscilloscopes, waveform generators, frequency counters, capacitance meters, and PC based computers. Specialty test equipment includes but not limited to logic analyzers, current probes, and temperature probes.
