3D printing post-processing

gets a 50x productivity boost

Mitsubishi Electric’s range of automation products helps to create the first fully

automated Underwriters Laboratories (UL) approved post-processing machine
for 3D printed plastic parts.

Technologies (AMT) has
teamed up with Mitsubishi
SElectric to further advance its
innovative chemical vapour smoothing
machine, PostPro 3D, by developing an
integrated automation solution. This is
based on Mitsubishi Electric’s MELSEC iQ-
F Series compact PLC, HMIs, SCADA and
MELFA articulated arm robots offered as a
system option. The PostPro vapour
