What to send for a 3D printing quote
The file formats we accept, the five details that make a quote accurate, and what happens between sending a file and getting parts.

A good quote comes back fast when we have what we need on the first message. Here's what to send.
The file
A STEP file is best: it keeps the exact geometry, so we can check wall thickness and fit accurately. STL, IGES, OBJ and 3MF work too. If you only have a drawing or a photo of an old part, send that; we can reverse engineer it into a CAD model.
Five details that make the quote accurate
- What the part is for. A display model, a functional test, an end-use part. This decides the process more than anything else.
- Quantity. One prototype and two hundred parts are quoted very differently.
- Material, if you know it. If you don't, tell us the conditions: heat, load, flexibility, chemicals, outdoor use.
- Finish. As printed, sanded, painted or machined.
- When you need it. A date helps us plan the build and pick a process that meets it.
What happens next
- Design review. An engineer checks the file for manufacturability and flags anything that might fail.
- Quotation. You get the recommended process and material, price and lead time.
- Manufacturing. Parts are produced with the selected technology.
- Post processing. Cleaning, finishing, machining or assembly, as the project needs.
- Inspection. Each part is checked for dimensional accuracy before dispatch.
- Delivery. Packed and delivered on the agreed date.
