Of course, all of the 3D model repositories we’ll be going over today accept STL files, meaning you can download 3D printable models in this format. As such, basically, all software related to 3D printing, like computer-aided design (CAD) programs and 3D slicers, is compatible with STL files. This method is fairly imprecise when it comes to capturing the size and shape of 3D models, but it’s good enough for 3D printing purposes. The actual way these files capture 3D models is through a triangular mesh, which is a series of interconnected triangular geometries. STL files are one of the most common formats for storing 3D model data as they’re relatively low in file size and are easy to manipulate. STL technically stands for Standard Triangle Language, but it’s almost always referred to as “STL” due to its file extension name, “.stl”. Considerations for 3D Printing Sites/DatabasesĪn STL file is a specific file format that’s meant to store 3D models.

In this article, we discuss curing resin, the various curing methods, and how to get the best results. Want to hear about more of the best places to find free STL files for 3D printing? Just keep reading! Printables is another great option that’s also completely free and has similar features to Thingiverse. Thingiverse contains millions of free models that are meant for 3D printing, and almost all of them are available in the STL format.

STL file sites that are specifically catered towards 3D printer users are better because they usually give designers space to list recommended print settings, and more of the STL files on the site will be actually 3D printable!īy far, the most popular site to find an STL file is Thingiverse. But not all of these sites are meant for 3D printing. Today, finding STL files is super easy as there are many different 3D model repositories that contain STL files. Cura, PrusaSlicer), and these programs turn the 3D part into a G-code file, which your printer actually uses to make the model. Moreover, STL files are accepted by basically every 3D slicer (e.g. While a 3D printer, such as the Creality Ender 3, can interpret or print an STL file directly, it’s the main format for storing 3D model data. STL files are the primary file format in the 3D printing space. Want to 3D print something? You’ll need an STL file first!
