First time using and I must say the quality for the part is excellent. The ordering and quoting was very good on the web site. The shipping and turn around time is 1st Class. I would recommend to anyone wanting a top quality part (or parts) and outstand shipping.
Ed Burks
I regularly use the 3D printing service that IN3DTEC offers and I'm very happy with the end products I receive as well as the quality of service. Parts arrive with very good dimensional accuracy and excellent finish. I also receive great advice about making my prints better. I definitely recommend IN3DTEC!
Dominik Dominiak
Working with in3dtec was great. The communication was really good - they responded always fast and to my satisfaction. Their statement about competitive prices is totally true and the quality is nothing to complain about. Hope in3dtec will continue with their great work. I will definitely order again.
