Our Story

About 423D Built

Bringing ideas to life through precision 3D printing and laser engraving, right here in the heart of Appalachia.

Born in the Mountains, Built for Tomorrow

Based in Bristol, Tennessee, nestled in the beautiful Appalachian Mountains, 423D Built was founded with a simple mission: to make advanced manufacturing accessible to everyone. We believe that great ideas deserve great execution, whether it comes from a Fortune 500 company or a garage inventor.

The "423" in our name is a nod to our area code and the community we are proud to call home. Here in the Tri-Cities region of Tennessee, there is a rich tradition of craftsmanship, resourcefulness, and pride in handmade work. We carry that tradition forward with modern tools.

From prototyping the next big product idea to creating personalized gifts that carry real meaning, we put care and attention into every single piece that leaves our workshop. Every layer printed and every line engraved represents our commitment to quality.
