3D Print Cost & Commercial Pricing Calculator
In short, Stop undercharging for your 3D prints. Calculate true manufacturing expenses — raw filament, electricity, nozzle wear, print failure rates, and labor — and price for sustainable profit.

The Real Math Behind 3D Printing Economics
Hobbyists often think: "My 50-gram print only used $0.90 of PLA, so selling it for $5 is great profit!" Then after six months, their nozzle wears out, their textured PEI sheet is scratched, they spend 20 minutes cleaning support scars, and Etsy charges a 6.5% transaction fee plus payment processing. Suddenly they are earning $2 per hour of their actual life.
Total Cost = (Filament Grams × $/g) + (kWh × $/kWh) + (Machine Hours × Wear/hr) + (Labor Minutes × $/min) + Scrap Buffer.
Machine Depreciation Isn't Optional
A $600 desktop 3D printer has an effective working life of roughly 2,500 to 3,500 print hours before motors, linear rods, bearings, and hotends need full overhaul or replacement. Budgeting $0.20 to $0.35 per printing hour ensures you accumulate a dedicated capital fund to replace worn components or buy next-generation machines without dipping into your personal wallet.
Commercial 3D Print Cost Breakdown Example (100g PLA Part, 4 Hours)
| Cost Component | Calculation Basis | Typical Rate | Total Cost ($) |
|---|---|---|---|
| Raw Filament | 100g PLA + 8% purge buffer | $20.00 / kg ($0.02/g) | $2.16 |
| Electricity | 100W avg draw × 4 hrs = 0.4 kWh | $0.18 / kWh | $0.07 |
| Machine Depreciation & Wear | 4 hours machine time ($600 printer / 1,500 hrs) | $0.40 / hr + $0.15 wear | $2.20 |
| Operator Labor | 10 min setup & support removal | $25.00 / hr | $4.17 |
| Suggested Retail Price (2.5x Markup) | Direct Production Cost: $8.60 | Commercial Profit Margin | $21.50 |
