## What it is
Strecs3D is a desktop preprocessor that optimizes 3D printing infill using built-in FEM stress analysis, assigning dense infill to high-stress regions and sparse infill elsewhere. It exports 3MF files with infill metadata compatible with major slicers like Cura, Bambu Studio, and PrusaSlicer.

## Use cases
- optimize 3d print infill based on stress analysis
- strengthen 3d printed parts without adding weight
- variable density infill generation from FEM results
- preprocess CAD models for slicers with stress-aware infill
- run structural analysis and generate infill maps in one tool
- export 3mf with per-region infill density for Cura or Bambu Studio

## When to choose
- you want stronger 3D prints at the same weight using simulation-driven infill
- you need an all-in-one workflow with built-in FEM, no external analysis licenses
- you use Cura, Bambu Studio, or PrusaSlicer and want to keep your existing slicer

## When to avoid
- you need uniform infill or simple slicer settings without structural analysis
- you print on platforms other than Windows or macOS
- you require Linux support or command-line batch processing

## Facets
- artifact type: application
