Features

Built for precision

Displacement Textures

Built-in and custom displacement maps. Amplitude in millimetres — no unitless coefficients.

Adaptive Subdivision

Control mesh density by max edge length in mm. Enough resolution for textures, light enough for slicers.

Real-Time Preview

3D viewport powered by Three.js. See the result before you export anything.

Symmetric Mode

Mirror displacement for perfectly symmetric textures. Essential for organic and repeating forms.

Clean STL Export

Watertight mesh, no holes, no T-junctions. Opens in OrcaSlicer and any other tool without issues.

Native Desktop App

Built with Tauri — small binary, native performance, no Electron overhead. Works offline.

Workflow

Load your mesh

Drag and drop any STL file. SurfEx parses it instantly.

Configure texture
