Wondering how much your 3D prints really cost? Let’s talk about 3d printing cost calculator.
Most hobbyists underestimate expenses like filament, electricity, and maintenance. This guide reveals exact cost-calculation methods and shares pro tips to save 30% or more.
Quick Summary:
-
- Filament costs = (Weight in grams) × (Price per gram)
-
- Electricity costs = (Print time × Printer wattage × Energy rate)
-
- Hidden costs: Maintenance, failed prints, labor

1. How to Calculate 3D Printing Costs (Step-by-Step)
1.1 Filament Cost: The Biggest Factor
Filament accounts for ~60% of costs for most users.
Formula: Total Filament Cost = (Model Weight in Grams) × (Filament Price per Gram)
Example:
-
- Printing a 50g model with PLA costing 0.03/g∗∗=∗∗0.03/g∗∗=∗∗1.50
Filament Price Table (2025):
| Material | Price per KG | Cost per Gram | Best For |
|---|---|---|---|
| PLA | $20 | $0.02 | Beginners, prototypes |
| ABS | $25 | $0.025 | Durable parts |
| PETG | $28 | $0.028 | Flexibility + strength |
Pro Tip: Use slicer software (like Cura, Bambu Studio) to preview model weight before printing.
1.2 Electricity Costs: Often Overlooked
A 3D printer uses ~50-150W depending on the model.
Formula: Electricity Cost = (Print Hours × Wattage ÷ 1000) × Energy Rate ($/kWh)
Example:
-
- 10-hour print at 100W, with electricity at 0.15/kWh∗∗=∗∗0.15/kWh∗∗=∗∗0.15
Electricity Rates by Country:
-
- USA: 0.10–0.10–0.30/kWh
-
- EU: €0.20–€0.40/kWh
-
- India: ₹5–₹8/kWh
1.3 Hidden Costs You Might Forget
A) Maintenance (20% of long-term costs)
-
- Nozzle replacements: 5–5–20
-
- Bed adhesives: $10/month
-
- Belt/tube upgrades: 15–15–50/year
B) Failed Prints (Wasted Filament)
-
- Average failure rate: 10–25% (higher for complex models).
C) Labor (For Businesses)
-
- Charge 5–5–20/hour if selling prints.
2. How to Reduce 3D Printing Costs by 30%+
3.1 Use Hollow Designs
-
- Slicer infill settings (15–20% is often enough).
3.2 Buy Filament in Bulk
-
- 5kg spools cost ~20% less per gram.
3.3 Print Overnight (Cheaper Energy Rates)
-
- Some utilities offer off-peak discounts.
3.4 Prevent Failed Prints
-
- Level your bed, dry filament, use rafts/brims.
3. FAQ: 3D Printing Cost Questions
Q: How much does it cost to 3D print a figurine?
A: A 100g PLA figurine costs ~2–2–4 (filament + electricity).
Q: Is 3D printing cheaper than manufacturing?
A: For prototypes/small batches—yes! Mass production? No.
Q: Why is my resin printing more expensive?
A: Resin costs 0.05–0.05–0.10/g + requires IPA cleaning.
