3D Printing Cost Calculator

How it's calculated: Material = weight (g) × price/kg ÷ 1,000. Electricity = power (W) × time (h) ÷ 1,000 × electricity price. Wear = purchase price ÷ lifetime (h) × print time (h) — reflects the printer's wear over its lifetime. The failure rate p is included as an expected value: surcharge = subtotal × p ÷ (1 − p). At 10 % failures you pay for about 11.1 prints per 10 good ones. The subtotal is material, electricity and wear. In seller mode, labour time, packaging and margin are added on top; the marketplace fee is calculated so your target margin still holds after the fee is deducted.
