3dSynth

What is 3dSynth?

3dSynth is a free browser tool from Kubuz that turns a drawn profile and a stack of slider-driven effects into textured vases, planters and lamp shades, with no modeling needed. You pick your printer, material and nozzle from hundreds of built-in machine profiles, draw a radius-to-height curve or start from a shape preset, and add effects such as ripples, noise, knurling, Voronoi cutouts, twists and top or bottom caps. A live 3D preview lets you scrub through the toolpath layer by layer.

G-code Sculptor writes spiral vase-mode G-code for your machine, so that route skips the slicer, and it can also save the shape as an STL, OBJ or glTF mesh. Mesh Sculptor sweeps a cross-section (circle, polygon, sine or a custom curve) along the profile, adds an optional inner wall and exports STL for your usual slicer. Texturize puts knurl, hexagon or custom heightmap patterns on any mesh, including an STL or OBJ you import.

It suits makers who like tuning surfaces and want more than a plain smooth vase. The extra modules (a node graph, Scratch-style blocks and a G-code editor) make the app busier than a single-form generator, so beginners do best staying in G-code Sculptor. The web app needs no account, and a one-time Premium license lifts the two-effect export cap.

What you can make

• Spiral vase-mode vases
• Textured planters and pots
• Single-wall lamp shades
• Solid vase meshes for your own slicer
• Textured versions of imported STL models

How to use 3dSynth

1. Open the web app and pick G-code Sculptor or Mesh Sculptor
2. Set your printer, material and nozzle in the Print tab
3. Draw the profile or pick a shape preset, then add effects and tune their sliders
4. Check the toolpath or mesh in the 3D preview
5. Download the G-code for your printer, or the STL for your slicer
