STEP to STL
STEP to STL - convert CAD models into STL meshes
This tool converts STEP and STP files into the STL format for 3D printing, simulations, web visualization, and technical mesh applications.
The generated STL files can then be further processed in slicers, CAD systems, or simulation programs.
Typical applications:
- 3D printing and additive manufacturing
- Slicer preparation
- Simulation and FEM
- Web preview of 3D models
- Data exchange with suppliers
What is STEP to STL used for?
The tool helps designers, engineers, and technical specialists quickly convert CAD geometries into triangulated STL meshes.
Especially suitable for:
- 3D printing and prototyping
- Simulation and analysis
- Visualization of CAD models
- Export for CAM and slicer systems
- technical presentations and reviews
How does the conversion work?
- Upload STEP or STP file
- Import CAD geometry
- Triangulate the 3D model
- Generate STL mesh
- Download the STL file
Depending on the configuration, the conversion can run on the server or locally in the browser.
Supported technologies
Modern open-source technologies are used for processing and conversion:
- Open CASCADE (pythonOCC)
- occt-import-js
- three.js
- meshio
Mesh options
Depending on the processing, various options are available:
- Triangulation accuracy
- linear deviation
- angular deviation
- ASCII or Binary STL
- optional browser conversion without upload
Current limitations
- Very large assemblies may be processed more slowly
- Server conversion requires additional CAD libraries
- Browser conversion does not support all complex geometries
- File size currently limited to 80 MB per file
