What file formats are accepted for 3D printing?

Most 3D printing services accept STL (most common), OBJ, 3MF, and STEP files. STL is the industry standard and works with all printers. 3MF is newer and preserves more information like color and materials.

How do I prepare my STL file for printing?

For best results: 1) Ensure the model is watertight (no holes), 2) Check the size/scale is correct, 3) Orient for minimal supports if possible. Most makers on 3D Print Bounty will help optimize your file if needed.

Can I print files from Thingiverse or Printables?

Yes! You can download STL files from Thingiverse, Printables, MyMiniFactory, or any other repository and upload them to 3D Print Bounty to get them printed. Just make sure the file license allows for personal use.

Preparing Your STL File

Don't worry if your file isn't perfect. Our makers can help optimize it. But here are some tips for best results:

Check the Scale

Make sure your model is the right size. Include dimensions in your project description (e.g., "should be 100mm tall"). Makers will confirm before printing.

Watertight Models

STL files should be "watertight" (no holes in the mesh). Most files from Thingiverse and Printables are already fixed. Makers can repair minor issues.

Include Multiple Files

If your project has multiple parts, upload all the STL files. Let makers know if parts should be printed in different colors.

Specify Material Needs

Tell makers if you need specific properties: food-safe, heat resistant, flexible, etc. This helps them recommend the right material.

Not sure if your file is ready?

Just upload it anyway. Our makers are experienced and can help fix common issues, suggest improvements, or answer questions about printability.
