Free 3D print pricing calculator. Enter spool cost, model weight, print hours, wattage, electricity rate, failure buffer, labor, and markup; outputs raw production cost, electricity overhead, wear allowance, and a tiered retail price.
Use when listing a new product on Etsy or quoting a custom job. Re-run with different markups to see your margin sensitivity.
Spreadsheets do this math but require setup. This is a 60-second quote tool.
Material cost = (spool price ÷ spool grams) × object grams. Electricity cost = (watts ÷ 1000) × print hours × $/kWh.
Failure buffer is a % surcharge on top of material + electricity. Labor is computed from prep/post-process minutes.
Suggested retail = raw cost × (1 + markup %). Etsy hobby sellers typically use 50–100% markup.
Etsy hobby sellers typically use 50–100% markup over raw cost. Adjust for product complexity and competition.
Bambu Lab printers average ~120 W; Ender-3 ~250 W during heating. The default is a balanced estimate.
It takes your model weight as a fraction of a full spool and multiplies by the spool price; a 25 g part from a 1 kg spool that cost 20 uses about 0.50 of filament. Failure buffer and wear allowance are then added on top.
Some prints warp, clog, or fail partway and waste filament and time, so charging only for perfect prints leaves you losing money over a batch. A small percentage buffer spreads that expected loss across every successful sale.

Raw $4.78 → Retail $7.17.
Material $2.00 + electricity $0.22 + failure buffer $0.22 + labor $7.50 (12-hour weighted) = $9.94, then markup. The number depends heavily on labor — the example uses a conservative slow-hourly.
