STL Analysis
STL analysis - check mesh quality online
This tool analyzes STL meshes for typical quality and geometry issues before 3D printing, CAM processing, or simulation.
The STL file is analyzed server-side and automatically deleted after processing.
What is STL analysis used for?
A valid mesh structure is essential for many technical applications.
Typical use cases:
- 3D printing and additive manufacturing
- CAM and CNC processes
- Simulation and FEM
- Mesh quality control
- Preparation of technical 3D models
Faulty meshes can cause problems during printing, simulation, or manufacturing.
What properties are checked?
The analysis checks various geometric and topological properties of the STL model:
- Non-manifold edges
- open edges and holes
- Watertight status of the mesh
- self intersections
- mesh consistency and topology
This helps identify typical issues early.
How does STL analysis work?
- Upload STL file
- Analyze mesh geometry
- Check topology and faces
- Detect errors and anomalies
- Display analysis results
Technologies used
Open-source technologies and Python libraries are used for the analysis:
- trimesh
- Python
- optional rtree and scipy extensions
Current limitations
- File size is currently limited to 80 MB per STL file
- The analysis is performed server-side
- Very complex meshes may take longer to process
- Some checks require additional Python extensions
