Tutorial 2: Superformula Starfish
Use the Gielis superformula to generate star-like, flower-like, or soft rounded profiles in a single Superformula node, then run them through a Vase Spiralizer for a printable organic vase.
What you'll learn
- Superformula parameters
m,n1,n2,n3and their visual effect - Wiring m and center (from Print Bed) for bed-centred prints
- How a complex silhouette stays one path before spiralizing
Prerequisites
- Tutorial 1 or equivalent comfort with the Node Sculptor canvas and Output
- A Node Sculptor project with the default printer profile
Step 1: Superformula and symmetry
Superformula
The Superformula node emits a closed path in the XY plane. The exponent n1 (especially < 1) deepens clefts; m steers how many “lobes” appear around the circle.
Step 1
Add Print Bed, Number (m), and Superformula
Add Print Bed → connect center → Superformula center. Add a Number (value 5), connect value → m on the superformula. Set n1 to 0.3, n2 and n3 to 1 (defaults can stay). Increase Segments to 256 for a smooth print.
Step 2: Vase Spiralizer to Output
Step 2
Vase Spiralizer and toolpath out
Add Vase Spiralizer; wire Superformula path → path. Set a modest End scale (e.g. 1.2) to flare the top. Connect Vase Spiralizer toolpath → Output Toolpath and export G-code when ready.
Node graph summary
| From | To | Sockets |
|---|---|---|
| Number | Superformula | value → m |
| Print Bed | Superformula | center → center |
| Superformula | Vase Spiralizer | path → path |
| Vase Spiralizer | Output | toolpath → Toolpath |
Outcome
A parametric “starfish” cross-section that spirals upward with taper—ideal for fast vase-mode prints.
