If you want to create a 3D model in STL format or edit an existing STL file in Windows 11/10, use these free STL editors.

A file with .stl extension is a 3D graphic file native to Stereolithography technology. Stereolithography is basically a type of 3D printing technology to create 3D models.

Since its creation, the STL file format hasn't changed much and is now considered the standard for 3D printing.

The most common reason an STL file may be not quite right is a mechanical connection where some piece isn’t quite as the designer expected, so the 3D model that interfaces with it no longer fits.

When you're done, click Design > Download for 3D Printing and you'll immediately get an STL file you can load into your printer.

PrusaSlicer has a new feature: the ability to import a CAD model for 3D printing. Starting in version 2.5.0-beta1, PrusaSlicer can import STEP format 3D models. An imported STEP file is converted t… ...

Thanks to skilled designers and the proliferation of 3D printing, you can build your version of the gorgeous Raspberry Pi case that Fractal Design doesn't seem interested in selling.

Now, rather than needing specialized skills and tooling to craft a duplicate Travel Sentry key, all you need is a 3D printer that can handle STL files (and that’s basically any 3D printer).
