Everything between the idea and the finished part
Most shops do one piece of the puzzle. We handle the whole path in-house, so you never have to translate between a designer, a print bureau, and a factory.
Product Development & CAD
Precision 3D models and manufacturing-ready drawings built from your sketch, sample, or napkin drawing — engineered to work before anything gets made.
Initial concepts start at $259

In-house printing puts a physical part in your hands fast. Test it, break it, refine it — we iterate with you until every detail fits.
Learn more →Tooling & Manufacturing
Runs from dozens to thousands of parts in-house — no tooling costs — plus tooling design and vetted partners when it's time to scale beyond that.
Learn more →Looking for something specific? We also do replacement & obsolete parts, jigs & fixtures for shops, and custom prototyping end to end.
A simple path, run by people who've walked it for 30 years
Tell us the idea
Send a sketch, photo, sample part, or just a description through our quote form. No CAD file required.
We engineer it
You get an honest assessment, a plan, and a price — then a precise 3D design built for real-world manufacturing.
Hold the prototype
In-house 3D printing turns the design into a part you can test. We revise together until it's right.
Make it for real
Short runs in-house, or tooling and production coordination when you need volume. Your IP stays 100% yours.
Inventors, shops, and manufacturers across Michiana
First-time inventors with an idea on paper. Machine shops that need a replacement part nobody makes anymore. Elkhart RV suppliers prototyping a new fitting. If it needs to be designed and made, it's our kind of project.
Three decades of turning ideas into products
Our lead engineer spent his career in precision manufacturing and rapid prototyping — 30+ years, 80+ products developed. Now we're bringing that experience home to South Bend, as a family-run shop that treats your idea like it's ours: protected, engineered honestly, and built to actually work.
