STEP to STL – convert CAD models to STL meshes
This tool converts STEP and STP files to STL format for 3D printing, simulations, web visualisation and engineering mesh applications.
The generated STL files can then be processed further in slicers, CAD systems or simulation tools.
Typical applications:
- 3D printing and additive manufacturing
- Slicer preparation
- Simulation and FEA
- Web preview of 3D models
- Data exchange with suppliers
What is STEP to STL used for?
The tool helps design engineers, engineers and technical specialists quickly convert CAD geometry into triangulated STL meshes.
Especially suitable for:
- 3D printing and prototyping
- Simulation and analysis
- Visualisation of CAD models
- Export for CAM and slicer systems
- technical presentations and reviews
How does the conversion work?
- Upload a STEP or STP file
- Import CAD geometry
- Triangulate the 3D model
- Generate an STL mesh
- Download STL file
Die Konvertierung erfolgt derzeit lokal im Browser — ohne Server-Upload.
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 processing mode, different options are available:
- Triangulation accuracy
- linear deviation
- angular deviation
- ASCII or binary STL
- optional browser conversion without upload
Current limitations
- Sehr grosse Baugruppen können langsamer verarbeitet werden
- Server-Konvertierung (Open CASCADE) derzeit nicht eingerichtet — Browser-Modus aktiv
- Browser conversion does not support all complex geometries
- Current maximum file size is 80 MB per file
