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.
Use AnyConv to convert STL files to formats like OBJ or STEP for further editing or integration with CAD systems.

What is a STEP file?
STEP (Standard for the Exchange of Product model data) is a widely adopted ISO standard (ISO 10303) for exchanging 3D CAD data between different software systems. It stores precise geometric and product structure information.
STEP files are ideal for sharing designs in engineering, manufacturing, and prototyping. They are compatible with most major CAD programs and ensure consistent model quality across platforms.
How to open STEP files
STEP files are supported by almost every CAD program, including SolidWorks, CATIA, Fusion 360, FreeCAD, and more. They are ideal for interoperability between platforms.
Use AnyConv to convert STEP files into STL, IGES, or other formats needed for 3D printing or further design.
