Where can I get a STEP file 3D printed?

Have a STEP file ready?

A STEP file, ending in .step or .stp, is an engineering format. It stores exact mathematical curves and surfaces rather than the triangle mesh an STL uses, which is great for a CAD program and not something our upload tool reads today. Here is what actually happens when you have one.

The fast path: export it yourself

If you have the CAD program that made the file, this is quicker than waiting on a review. Open the STEP file, find Export or Save As in the file menu, and choose STL or 3MF as the output type. Most CAD tools, including free ones, can do this in a few clicks. Then upload that exported file here for a price the moment it finishes reading.

A STEP export usually needs one setting checked: the mesh resolution or tolerance, sometimes called chord height. A finer setting makes a smoother STL but a bigger file. The default setting in most programs is fine for a printed part.

The honest path: send it to a person

No CAD program handy, or not sure how to export? Go to our upload tool and drop the .step file in anyway. It will tell you plainly that it takes STL and 3MF files, and it gives you a button to send this file for review instead of turning you away with nothing. That puts the same file you already have in front of a person, along with any material and color you already picked.

You add your email and a short note about what you need, and that is the whole form. We reply by email once someone has actually opened your file. There is no promised reply time here, because nobody has one to promise, but the file and your setup are saved the moment you send them: you do not start over.

What to do with a STEP file, step by step

1. Step 1

   Try exporting it first

   If you have the CAD program, use Export or Save As, and choose STL or 3MF.

2. Step 2

   Upload the exported file

   Drop the new STL or 3MF into our upload tool for a price right away.

3. Step 3

   No CAD program? Upload the STEP file anyway

   Drop the .step file in. The tool will say it takes STL and 3MF, with a button to send it for review.

4. Step 4

   Add your email and a note

   Say what the part is and what you need. Nothing else is asked for.

5. Step 5

   Wait for a reply by email

   A person opens the file and writes back with what they found, once they have actually looked at it.

Have the file? Upload it.

Can you 3D print a STEP file?

Not with an instant price, since our upload tool only prices STL and 3MF. Export the STEP file to STL or 3MF yourself for the fastest path, or send the STEP file for review and a person will look at it.

How do I convert a STEP file to STL?

Open it in the CAD program that made it and use Export or Save As, choosing STL or 3MF as the file type. Most CAD tools, free and paid, support this.

Will sending a STEP file for review cost more?

Sending a file for review does not cost anything by itself. A person tells you the price once they can see what the part actually needs.

How long does a review take?

We do not promise a reply time, since nobody owns that number yet. You get an email once a person has looked at your file.

Have the file? Upload it.
