When to Use 3MF Simplifier
3D Printing Workflow
Reduce polygon count for faster slicing in modern 3MF-compatible slicers and Windows 3D Builder.
Multi-Material Models
Simplify complex multi-material 3MF models while preserving material assignments.
File Size Reduction
Smaller 3MF files for easier sharing and cloud storage.
How It Works
Our simplifier parses your 3MF file, extracts the mesh geometry, applies meshoptimizer's Quadric Error Metrics algorithm to reduce polygon count, and outputs a new 3MF file with simplified geometry.
3MF files support multi-material models, textures, and metadata. Simplification preserves material assignments while reducing polygon count.
Upload your 3MF file, adjust the target reduction percentage, and download the simplified result.
