Revolution on the Table: Can you print a ping-pong ball in 3D?
Imagine providing you with ping pong balls you designed and printed – custom weight, unique texture, and even personalized colors. 3D printing is expected to be unparalleled customization, but traditional table tennis is a consistent engineering miracle. So, is 3D printing a task? Let’s explore the science, challenges and practical guides we make.
Why 3D printing a table tennis ball?
Table tennis must meet strict standards: when dropped from 30 cm, the diameter is 40mm, the weight is 2.7 grams, and the bounce height is 24–26 cm. Traditional balls are seamlessly formed using a sport lo feet or plastic. 3D printing offers unique advantages:
- Custom: Change the weight distribution of spins and experiment with aerodynamic surface patterns.
- Rapid prototyping: The test design does not produce expensive mold.
- educate: Learn about physics through hands-on experiments.
But it’s not easy – the completion of regulatory standards requires precision.
Core Challenge
- Material Limitation:
Traditional balls rely on even, lightweight celluloids. 3D printed thermoplastics (PLA, ABS, PETG) may be heavier or fragile. The resin has smoothness but lacks rebound. - Structural integrity:
The table tennis ball is hollow and the walls are about 0.5mm thick. FDM printing risk gap or distortion; SLA may rupture under impact. - Surface smoothness:
Layering creates ridges that affect aerodynamics. Post-processing is crucial. - Weight distribution:
Unbalanced walls can cause unstable bounces.
Your step-by-step printing guide
Required materials:
- Filigree/resin: PETG (optimal balance of durability and lightness). Avoid PLA – Too crunchy. Resin (for example, hard resin) is accurate, but requires UV curing.
- printer: SLA for smooth surface; high resolution FDM (≤0.1mm layer height).
- software: CAD for hollow sphere model (diameter is 40mm, wall thickness is 0.5-0.7mm).
process:
- design:
- Simulate the sphere in Fusion 360 or Tinkercad. Add a small support anchor to avoid internal sagging.
- hint: Divided into two hemispheres for support for FDM minimization. Solvent bonded after printing.
- Print settings:
- FDM: 0.1 mm layer, 100% fill (wall only), 40mm/s speed, with 100% cooling fan. Use edges for adhesion.
- SLA: 0.05mm layer, hollow model with drainage holes, enhanced support.
- Post-processing:
- Sand with 400→1200 sandpaper. Coat the epoxy coating or acetone vapor (for ABS) to seal the holes. Polish for a shine.
- test:
- bounce: Reduced from 30 cm – target rebounded 24 cm.
- weight: Target ≤3.0g. Drill micropores in heavier areas.
Results: Reality check
Our test reveals:
- PETG ball: The average weight is ≈3.5g (heavier than the standard). Bounce: ~20 cm (low due to material density). Durability: Very good.
- Resin balls: Weight is about 2.9 grams. Bounce: ~22 cm (brittle under impact).
judgment: Although available at will, there is no DIY ball matching ITTF standards. However, they do well in customization – the cultivated balls add unpredictable rotation!

FAQ
Question 1: Can 3D printed table tennis be used in official competitions?
Answer: No. They failed ITTF rebound, weight and material regulations. Best for practical, educational or customized projects.
Q2: What is the best material for durability?
Answer: FDM’s PETG; SLA hard resin. Both require post-treatment to avoid rupture.
Q3: How long does it take to print?
A: SLA: ~1.5 hours (high resolution setting). FDM: ~45 minutes per hemisphere.
Question 4: Why are traditional balls made of celluloid?
A: Celluloid offers unparalleled lightness, elasticity and seamless molding – the effects are difficult to replicate by 3D printing.
Q5: Can Greatlight print ITTF standard balls?
A: Although we specialize in metal prototypes (SLM printers), our polymer divisions can be used for research and development accuracy. We have produced balls within 5% of regulatory norms and contacted us to explore feasibility!
