How to Get Your STL Printed and Shipped
Check the file in your browser for units, size and holes, then the five steps from upload to the parcel at your door.
You have the STL and no printer, or no time to babysit one. Getting it printed takes about a minute of your time: upload the file, see the price, pick a plastic and colour, pay. What decides whether it comes back right is the file itself, and most first orders that go wrong go wrong in the same few ways. Check yours here first. It is read on your own computer and never uploaded.

The mistake to avoid
Export in millimetres, at the real size you want in your hand.
WhyAn STL is a list of numbers with no unit in it. We read them as millimetres, as slicers do, so a model drawn in inches arrives 25.4 times too small.
Before you upload
- Units
- Export in millimetres. If the checker shows a 2 mm part you meant to be 2 inches, re-export it; we print the numbers in the file.
- Size
- The longest side has to fit 255 mm, the build size of the Bambu Lab printers we run. Anything bigger splits into pieces that each fit, with pins or a joint to put them back together.
- A closed surface
- Every edge should be shared by exactly two triangles, so the slicer can tell inside from outside. Holes and overlapping shells are the usual reason a print comes back with gaps.
- Faces the right way out
- Inside-out triangles are the one problem we repair automatically on upload. Everything else is printed as drawn.
OBJ, 3MF and STEP files are welcome too; draw them in millimetres as well. For a part that has to fit something else, measure it first and draw the hole to suit.
Getting it printed
- 1. Upload
- Drop the file into our online 3D printing service. It is sliced on the printers’ own profile, so the weight, print time and price come from your model, not a guess from its size.
- 2. Choose
- PLA for most things; PETG, ABS, ASA or TPU when a part needs heat resistance, weather or flex. Pick a colour and how many.
- 3. Pay
- Make an account at checkout and pay by card. There is no quantity minimum; every order is at least $5 before postage.
- 4. Printed and checked
- Every part is printed on Bambu Lab printers and checked before it is packed.
- 5. Shipped
- Orders ship in 3 to 7 business days, tracked, with the postage quoted for your address before you pay.
For what one part costs against ten, see 3D printing with no minimum, and for how materials compare, PLA vs PETG.
FAQ
Upload it on the parts page. It is sliced in seconds and you see the price per part before making an account. Choose a plastic, a colour and a quantity, pay at checkout, and it ships in 3 to 7 business days.
Millimetres. An STL has no unit inside it, so we read the numbers as millimetres, as slicers do. A model exported in inches arrives 25.4 times too small.
Up to 255 mm on its longest side. Larger parts can be split into pieces that each fit and joined after printing.
We fix inside-out faces automatically. Holes in the surface and overlapping shells are printed as they are, so repair them in your CAD program and export again. The checker on this page finds them.
