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 and edited in most 3D modeling and slicing programs such as Blender, Cura, TinkerCAD, or Fusion 360. They represent the geometry of 3D objects using triangles and are essential for prototyping and 3D printing workflows.
Use AnyConv to convert STL files to formats like OBJ or STEP for further editing, or to generate GCODE directly for 3D printing. It’s a fast and convenient way to prepare your models online without installing extra software.
