What is a STL file?

STL (Stereolithography) is one of the most common 3D file formats used for 3D printing. It describes the surface geometry of a 3D object without including color, texture, or other attributes.

STL files are supported by virtually all 3D printers and modeling software. They are lightweight and easy to process, making them the go-to choice for rapid prototyping and additive manufacturing.

How to open STL files

STL files can be opened in most 3D modeling and slicing programs such as Blender, Cura, TinkerCAD, and Fusion 360. They are essential for 3D printing workflows.
