The Charm of Infinity Cube: Your Final 3D Printing Guide
There is something fascinating about the infinite cube. This stylish geometric puzzle folds unfold endlessly, seamlessly transforming as it moves through the fingers. Apart from being a charming desktop toy, this is an excellent project to explore the possibilities of 3D printing. Whether you’re an amateur experimenting at home or an engineer testing prototypes, use precise mechanisms to create the creativity of infinite cubes. In this guide, we will browse design, print and assemble this fascinating object, and even explore how to use professional-grade materials to enhance it.
Why print an infinite cube?
There are good reasons why Infinite Cubes are fascinating:
- Educational Value: They teach space mechanics and rotational kinematics.
- Portable stress relief: A tool for tactile irritability in your pocket.
- Excellent display cabinet for design/printing: Highlight dimensional accuracy, material flexibility and surface quality.
- Customizable: Scale it, brand or adjust the geometry – your design and rules.
Step by step guide to printing infinite cubes
1. Design considerations
The infinite cube consists of 8 smaller cubes connected by thin ligaments in a continuous chain. Key design aspects:
- Hinge accuracy: The ligament holes must be perfectly aligned and sized to smooth the rotation. Each pin allows 0.2–0.3 mm clearance to minimize friction without swinging.
- Modular: Design one "part," Then copy it in the CAD software 8 times. The Fusion 360 or Tinkercad works well.
- Thick wall: Aim at 1.5–2mm wall/cover to prevent rupture.
For prompts: Download the free STL (such as Thingiverse #788466), but make sure the tolerance of the needle diameter matches the printer.
2. Material selection
| Material | advantage | The best use |
|---|---|---|
| PLA | Easy to print, low warping, bright colors | Beginners, decorations |
| Petg | Higher durability, better impact resistance | Reuse toys |
| Nylon/TPU | Extreme flexibility of smoother hinges | Experienced users seeking butter exercise |
| Metal (SLM) | High-quality weight, industrial durability, heat resistance | Professional prototype, high-end gift |
For metal cubes:SLM (Selective Laser Melting) technology combines fine metal powders. Materials such as aluminum, stainless steel or titanium provide unparalleled strength. This requires professional equipment – and then do it later.
3. Print settings
- Layer height: 0.1-0.15mm, for clean hinges.
- filling: 20–30% capacity balance stiffness.
- speed: ≤40mm/s for hinges and small parts.
- cool down: 100% fan to prevent ligament from sagging.
- Adhesion: Edge/raft to reduce warping on the hinge.
4. Post-processing
- pin: Use 1.75 mm filament pieces (friction fit) or stainless steel rods (for laser cutting of metal cubes).
- Deburring: Drill light holes by hand. Polished parts with 400 grains of sandpaper.
- lubricating: Smooth the dry ptfe spray on the connector.
5. assembly
Use the clip segment as a foldable chain, insert the pin into the ligament hole, and secure it with a drop of water UV resin Or Ca glue. for Metal cubesepoxy or pressure-fixed pins are ideal.

FAQ: Infinity Cube 3D Printing
Q: Can I print an infinite cube without support in 3D?
A: Absolutely – The design section is flat to avoid overhanging. Ligaments and cubes should touch the build plate.
Q: Why does my Infinity Cube feel stiff after assembly?
A: It may rub against tight jacks. Use a drill or sandpaper drop to target the small holes with a minimum hole. Lubricate joints.
Q: How to scale a cube without affecting the function?
A: Scaling evenly (all axes together!). Ensure the hinge needle diameter scale to maintain rotational smoothness.
Q: What is the maximum size that a metal infinite cube can achieve?
A: Each section up to 150mm cubes are designed to be used with SLM printing and Greatlight calibration – ideal for building models or industrial demonstrations.
Q: How much does a metal infinite cube cost?
A: Prices vary by size, material and finish. The price of 50mm aluminum cube post-treatment is about $150-300. Contact a manufacturer, such as Greatlime, for instant quotes.
