How to Reduce 3D Printing Cost

Proven strategies to cut your 3D printing costs by up to 40%. Learn material optimization, energy savings, and waste reduction techniques.

Material Cost Reduction (Save 20-30%)

1. Optimize Infill Percentage

Most prints don't need 100% infill. Reduce infill to 10-20% for decorative items and 20-30% for functional parts. This can save 30-50% on material costs.

Example: A 100g print with 100% infill uses 100g of filament. At 20% infill, it uses only 40g - saving 60g (£0.77 at £0.0128/g).

2. Use Wall Thickness Wisely

Reduce wall thickness from 3-4 layers to 2-3 layers for non-structural parts. This can save 15-25% material without compromising appearance.

3. Minimize Support Material

Design parts to minimize overhangs, use tree supports instead of standard supports, and orient prints to reduce support needs. Save 10-20% on support material.

Energy Cost Reduction (Save 10-15%)

4. Optimize Print Speed

Faster prints consume less energy per part. Increase print speed by 20-30% where quality allows. Use faster speeds for infill and inner walls.

5. Reduce Bed Temperature

Lower bed temperature by 5-10°C if adhesion allows. This reduces energy consumption by 5-10%.

6. Batch Printing

Print multiple parts simultaneously to share heating costs. One 8-hour print uses less energy than four 2-hour prints.

Waste Reduction (Save 5-10%)

7. Reduce Failed Prints

Use proper bed leveling, first layer calibration, and test prints. Failed prints waste 100% of material and energy.

8. Recycle Failed Prints

Invest in a filament recycler or send failed prints to recycling services. Recover 50-70% of material value.

9. Optimize Rafts and Brims

Use brims (thin) instead of rafts (thick) when possible. Brims use 80% less material than rafts.

Bulk Purchasing (Save 10-20%)

10. Buy Filament in Bulk

Purchase 5kg or 10kg spools instead of 1kg spools. Bulk purchases typically save 15-25% per kilogram.

11. Choose Budget-Friendly Brands

Quality budget brands like Sunlu or Overture offer 20-30% savings compared to premium brands with minimal quality difference for most prints.

Quick Wins Checklist

  • ✓ Reduce infill to 10-20% for decorative items
  • ✓ Use 2-3 wall layers instead of 4
  • ✓ Enable tree supports in slicer
  • ✓ Increase print speed by 20-30%
  • ✓ Lower bed temperature by 5-10°C
  • ✓ Print multiple parts together
  • ✓ Buy filament in bulk (5kg+ spools)
  • ✓ Use budget-friendly brands
