A professional toolpath synthesizer for creative 3D printing. Design with parametric splines or program custom logic visually with SynthBlocks. Skip the slicer entirely.
Prefer to try first? Try free in browser. Desktop app available for Windows, macOS, and Linux.
3dSynth bypasses traditional mesh-based workflows entirely. Your printer receives instructions generated directly from parameters you control.
Build toolpath logic visually—loops, math, conditionals, and custom behaviors. Designed for creative technologists.
Parametric spline profiles + modulators to sculpt form. Fast iteration without mesh artifacts.
Preview the exact toolpath before you print. Inspect layers, travels, and retractions in the viewport.
Built-in configuration for major brands. Select your machine and export with safe start/end G-code.
Stack Ripple, Twist, Noise, Blobs, Contour Waves, and Fractals. Mix and match to discover new surfaces.
Switch between Spiral Vase mode (continuous Z) and layered workflows. Discover woven textures.
Fast, clean workflow with efficient panels and clear visual feedback—built for iteration.
Choose your workflow. Design with parametric curves or program custom logic visually.
The classic vase-mode workflow. Draw a spline profile and stack powerful modulators to sculpt the form.
Program your toolpath directly. Drag and drop blocks to build custom loops, patterns, and logic.
From subtle textures to structural patterns—generate toolpaths defined by parameters and logic, not polygons.
Real prints made with 3dSynth. From screen to physical form.
Get productive fast. Then go deep: blocks, effects, transforms, and real printing workflows.
