Profile Shape

Parametric splines + stackable modulators

Draw a Bézier profile, layer 31+ effects, export vase-mode G-code. No mesh, no slicer.

Overview

How it works

Profile Editor maps height (Z) to radius via Bézier spline. Effects stack applies procedural displacement. Output: single-perimeter vase-mode G-code.

Workflow

Draw profile → add modulators → optionally use Julia Stack or Contour Wave → export G-code.

Spiral Vase (default): continuous Z spiral. Contour Wave: woven lattice, phase-shifted layers.

Key concepts

Profile · Effects stack · Modulator · Growth curve · Effect layer range · Vase mode

Profile Editor

Define your silhouette

X = radius, Y = height. Each point = target radius at that Z. Total height sets print extent.

Presets: Vase, Cone, Cylinder, Bowl. Controls: drag point/handle, right-click delete, double-click add. Shift+drag for symmetric handles.

Print-safe: Avoid thin necks, smooth transitions, watch self-intersections.

Projects: Save .3dsynth and design presets.

Shape Modes

Beyond the spline

Julia Stack

Experimental

Replaces profile with quadratic Julia set boundaries per layer; morphs over Z.

Julia Stack Example

Contour Wave

Woven lattice; Z oscillates per layer, phase-shifted 180° between layers.

Contour Wave Example

Pattern Offset

Per-effect

Repositions effects in (θ, Z) space—domain/positioning, not a shape mode.

Effects

Order matters: top to bottom. Base texture (e.g. Noise) first, caps last.
