Where Innovation Meets Craft

We’re not just another print service—we’re a product of the place we call home. Northstate Additive was founded in Redding, California, where innovation doesn’t come from glass towers—it’s built in garages, on ranches, in machine shops, and around kitchen tables.

Surrounded by redwoods, rivers, and rugged landscapes, our roots are in the industries that shaped Northern California—lumber, agriculture, fishing, and high tech. That legacy drives our approach: hands-on, no-nonsense, and relentlessly practical.

What We’ve Made So Far

From mechanical parts to art pieces, our prints are built to impress. Explore our latest creations and see what’s possible.
