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

  1. What the part is for. A display model, a functional test, an end-use part. This decides the process more than anything else.
  2. Quantity. One prototype and two hundred parts are quoted very differently.
  3. Material, if you know it. If you don't, tell us the conditions: heat, load, flexibility, chemicals, outdoor use.
  4. Finish. As printed, sanded, painted or machined.
  5. When you need it. A date helps us plan the build and pick a process that meets it.

What happens next

  1. Design review. An engineer checks the file for manufacturability and flags anything that might fail.
  2. Quotation. You get the recommended process and material, price and lead time.
  3. Manufacturing. Parts are produced with the selected technology.
  4. Post processing. Cleaning, finishing, machining or assembly, as the project needs.
  5. Inspection. Each part is checked for dimensional accuracy before dispatch.
  6. Delivery. Packed and delivered on the agreed date.
