Note: Weight and cost calculations factor in the infill percentage. Actual print weight may vary slightly based on wall thickness, supports, and printer settings.
Understanding 3D Printing & Modeling
Geometric Formulas Used
The calculator uses standard geometric formulas to determine volume and surface area:
Cube: V = a³, A = 6a²
Prism: V = l × w × h, A = 2(lw + lh + wh)
Sphere: V = ⁴⁄₃πr³, A = 4πr²
Prism: V = l × w × h, A = 2(lw + lh + wh)
Sphere: V = ⁴⁄₃πr³, A = 4πr²
Common Material Densities
- PLA: ~1.24 g/cm³ (Most common, easy to print)
- ABS: ~1.04 g/cm³ (Durable, requires heated bed)
- PETG: ~1.27 g/cm³ (Strong, chemical resistant)
- Resin: ~1.15 g/cm³ (High detail, requires UV curing)
- TPU: ~1.21 g/cm³ (Flexible, rubber-like)
Understanding Infill
Infill is the internal structure of a 3D print. It is never 100% solid (unless specified) to save material and time.
- 0-15%: Decorative models, low strength
- 20-40%: Standard functional parts (Recommended)
- 50-100%: High-stress mechanical parts
Cost Optimization Tips
- Scale down: Reduce size if possible to save cubic volume
- Optimize infill: Use 15-20% gyroid or grid for best strength-to-weight ratio
- Hollow models: Use 0% infill with adequate wall thickness for display pieces
- Buy in bulk: Filament cost per kg drops significantly for 5kg+ spools
