Free 3D Printing Tools
Free 3D printing tools that turn what you already have — a logo, a photo, a name or a broken model — into a file your printer can use. Each one runs in your browser with a live preview, so you see the result before you download.

Free 3D printing tools FAQ
Are these 3D printing tools really free?
Yes. Every tool on this page is free to use without an account or a watermark. There's a fair-use daily limit per visitor (for example 20 models a day in the image, text, lithophane and cookie cutter tools, and 5 repairs a day in the STL repair tool).
Which file do I get?
The model makers and the repair tool give you a watertight STL that opens in Bambu Studio, PrusaSlicer, OrcaSlicer and Cura. Logo signs and name plates can also be made in two colors — you then get a 3MF with both colors already assigned. The QR code generators export SVG or PNG, and the Google review QR code generator also prints a ready-made sign.
Do I need 3D modeling skills?
No. Each tool works from something you already have — an image, a photo, a name or an existing model — and shows a live preview, so you can see the result before you download it.
What happens to my uploads?
Your image or model is only used to create the file. Uploaded images are never stored, and generated files are deleted from our servers after 24 hours.
I don't have a 3D printer. Can you print it for me?
Yes. After you generate a model, click “Get an instant print quote”. We print it on a Bambu Lab H2C in PLA or PETG and ship it to you. You can also upload your own STL, 3MF or OBJ on our 3D printing service page.
