Stanford Bunny: Cosmic Voronoi Easter

Stanford Bunny: Cosmic Voronoi Easter  🪐 👽

Procedural transformation of the iconic Stanford Bunny into a futuristic, multi-layered sculpture using Geometry Nodes in Blender.

Background

Scanned in 1994 by Mark Levoy and Greg Turk at Stanford University, the "Stanford Bunny" was one of the first high-quality seamless 3D scans available to researchers. Since then, it has become a popular geometric structure for testing various spatial algorithms and computational methods.

Working with the "Stanford Bunny" model is an inspiration to me and also a tribute to the computer graphics world :) 

Design Concept

The source model has been heavily transformed into a futuristic, multi-layered, and multi-material sculpture. All modifications were made procedurally in Blender using Geometry Nodes.

My modified Bunny consists of three distinct layers:

• The Inner Core (Green): A reduced in size and polygons version of the bunny, "glowing with an internal energy".

• The Reinforcement Mesh (Black): A thin, structural wireframe "holding the green energetic core".

• The Protective Shields (White): Translucent protection plates inspired by eggshells or ceramic thermal insulation tiles.

The main advantage of procedural design is that you can easily change a few parameters and instantly get a new shape:

Fabrication

To 3D print this, I split the Blender model into three separate STL files. I sliced the multi-object model for Prusa MK3S printer with the Prusa Multi-Material Unit (MMU). This allowed me to simultaneously print all three materials  ( the glowing core, the black wireframe, and the white shell )  as a single, solid object.

I am pretty happy with the resulting shape, color combination, and tactile feel. 

🛠 3D Printing Setup:

• Printer: Prusa MK3S + MMU2S

• Nozzle diameter: 0.4 mm

• Layer height: 0.20 mm

• Material: PLA filament (3 colors)

  • Green core 

    • Perimeters: 3

    • Infill: Gyroid 15%

  • Black wireframe

    • Perimeters: 10

    • Infill: no infill, just perimeters

  • White shell

    • Perimeters: 10

    • Infill: no infill, just perimeters

• Brim: outer brim 10 mm

• Supports: auto generated (grid)

• Seam position: aligned

• Wipe tower: purging volumes range from 140 to 300 depending on color transition

Have a great printing! Feel free to remix and modify my original design in Blender. I would be happy to see your 3D printed results in various colors. Please let me know in the comments if you have any questions.

Thank you!  💚
