About This Tool
Conceptually, the workflow parses vertex data, expands polygons to triangles, assigns normals from winding or computed cross products, and writes the STL in the chosen format. Optional features include deduplicating vertices and controlling decimal precision.
Who benefits: 3D printers, product designers, asset developers; Use cases: preparing models for slicers, archival storage, and pipeline automation. Unique value: explicit handling of unit scaling and format choice, with a clear conversion report.
Core features include triangle generation, unit scaling, ASCII/binary output, basic integrity checks, and a downloadable report.
How to Use
- Upload OBJ file and set output_format (ASCII_STL or BINARY_STL) and unit_scale.
- Optionally enable merge_duplicate_vertices and set output_precision.
- Run conversion.
- Download STL file and optional report.
- Validate in your slicer; adjust unit_scale if needed.
