Can I Send an STL File to a 3D Printing Service?

What to include with an STL, OBJ, 3MF or STEP file when requesting a professional 3D print quote.

01

The file is only one part of the brief

A printable file describes geometry, but it does not necessarily explain the intended physical size, quantity, use, color, finish expectations or deadline. Include that context with the upload.

02

Confirm units and target dimensions

STL files do not inherently carry reliable unit information in the same way as some CAD formats. State the intended dimensions so scale is not inferred incorrectly.

03

Explain what the object must do

A visual prototype and a load-bearing bracket may need different material and print decisions even if both files are technically printable. Intended use helps prevent inappropriate assumptions.

04

Expect a model check

Meshes can contain holes, intersecting shells, extremely thin features or details that are difficult to manufacture at the requested size. A quote may therefore include questions or file-preparation work.

Questions about this project type

Which formats can I upload?

The current request workflow accepts STL, OBJ, 3MF, STEP and STP geometry files.

Do I need to choose a material before requesting a quote?

No. If you are unsure, describe the intended use and the material can be discussed in context.
