Made by Machinists

We’ve spent our careers prototyping and manufacturing and we wanted to make the kind of desktop CNC mill we would want to use.

The Semp DTM365 was designed to be the machine that works in the materials we actually use, with quick setups.

We know that you don’t want to spend a long time learning new tools and processes so we tried to take all the guess work out.

We know you just want to get your parts made quickly.
