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 GCODE file?

GCODE is a machine control language used to instruct 3D printers and CNC machines. It defines movement paths, speeds, temperatures, and other commands required to manufacture a physical object layer by layer.

GCODE is generated by slicing software from 3D models, typically in STL or OBJ format. It’s essential for the additive manufacturing process and widely supported across all major 3D printer platforms.

How to open GCODE files

GCODE files are opened with 3D printing and CNC control software like Pronterface, Repetier-Host, Cura, or OctoPrint. They allow users to preview print paths and edit print parameters.

While not a design format, AnyConv supports converting model files to GCODE indirectly by preparing them for slicing software which generates GCODE commands.

Key facts about GCODE

  • Full name: G-code File
  • Extension: .gcode
  • MIME type: text/x.gcode
  • Developed by: Numerical Control Community
  • Initial release: 1958
