Common questions.

A STEP file plus a drawing (PDF) for each part is ideal — the model for geometry, the drawing for tolerances and notes. For flat parts, a DXF or DWG works. If you only have one of those, send what you’ve got; we can often quote from a model alone, and if you don’t have a model at all, we can help build one.

Usually within 24 hours, and 48 at the most. If a job needs a closer look, we’ll tell you up front rather than leave you waiting.

No. One piece or one thousand — prototypes, short runs, and replacement parts are all welcome.

Most common metals and engineering plastics — aluminum, steel, stainless, titanium, brass, copper, Delrin, nylon, PEEK, and more. The full list is on the Materials page; if your part needs something specific, just ask.

It depends on the part and the process. Standard machining runs around ±0.005 in, with tighter tolerances held on request — down to ±0.0001–0.0002 in for ground and wire-EDM work. We quote the actual tolerance for your part, and we inspect to it.

ACH, wire transfer, or company check. POs are welcome from established businesses — just include yours when you approve the quote.

Yes. Send a sketch, a drawing, or even a physical sample, and our engineers can build the 3D model for you. Recreating a part from an existing sample — reverse engineering — is something we do regularly.

Both. A single prototype, a short bridge run, or full production — there’s no minimum, and we can help you move from a prototype to a production-ready design when you’re ready.

We’re located in Michigan and ship nationwide. Send your files from anywhere — the process is the same.

We focus on commercial parts. We don’t quote firearms, defense (DoD), ITAR, or EAR-controlled work.
