BREP in het kort
BREP
Boundary representation became a core idea in 1970s and 1980s solid modeling, and Open CASCADE's .brep files reflect that tradition by serializing exact topological and geometric entities for native CAD workflows.
STL in het kort
STL
STL is strongly associated with stereolithography and the early practical history of additive manufacturing.

Wanneer je elk formaat gebruikt
When to use BREP
- Your source file is already in BREP.
- Preserve source expectations before exporting to STL.
- BREP is commonly used in cad workflows.
When to use STL
- Your target workflow expects STL.
- Improve delivery compatibility with STL.
- STL is commonly used in cad workflows.
Veelgestelde vragen
Why convert BREP to STL?
Convert to STL when preparing a model for 3D printing, mesh repair, or broad geometry-only interchange where materials and metadata are unnecessary.
It is ideal for fabrication handoff and simple printable mesh exchange.
For richer print metadata, 3MF is often the better target.
What changes when converting BREP to STL?
This conversion changes how the format behaves in downstream tools and delivery environments.
What should I review after converting BREP to STL?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
