Excellent 4.9 out of 5

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

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

Exceptional service, always willing to work with the customer to ensure parts are built to spec. Quick, reliable turn around, high quality and reasonably priced CNC/3D Printed parts.

Ron Miranda

My experience working with the team at IN3DTEC was wonderful. The team was easy to work with and provided me with useful feed back about my design. Also the price was just right.

Evan Kuester

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.

How Does CNC Turning Work?

Design & Programming – A CAD model of the part is created and converted into machine instructions (G-code).

Material Setup – The raw material (bar or rod) is clamped securely in the lathe’s chuck.

Rotation – The workpiece spins at high speed while the cutting tool remains stationary.

Precision Cutting – Computer-controlled tools move along multiple axes to shape the material into the desired geometry.

Finishing – Additional processes like drilling, threading, or knurling are performed for accuracy and surface finish.

Final Inspection – The finished part is measured to ensure it meets specifications.
