About This Tool

This online tool converts STL (Stereolithography) 3D model files into G-code instructions for 3D printers and CNC machines. Upload your STL file, customize printing parameters like layer height, infill density, print speed, and temperature, then generate optimized G-code ready for your machine. The tool processes the 3D geometry, slices it into layers, and generates precise movement commands. All processing happens securely on our servers - no software installation required.

Frequently Asked Questions

Find Quick Answers

What STL file formats are supported?

The tool supports both ASCII and binary STL formats, which are the standard for 3D printing. Files must have the .stl extension.

What G-code flavor does this tool generate?

The tool generates generic G-code compatible with most FDM 3D printers (Marlin, RepRap, etc.). You can adjust machine-specific settings in the parameters.

Is there a file size limit?

Files up to 50MB are supported. For larger files, consider using desktop slicing software.

Can I preview the sliced model?

Currently, this tool focuses on G-code generation. For visualization, use dedicated 3D printing software that can load and preview the generated G-code.

Are the processing parameters saved?

Parameters are only used for the current conversion session. For repeated use with the same settings, save your parameter values externally.
