What Does a 3D Print Cost? The Real Breakdown
Updated June 2026 · By the PrintProfit team
"It's just a bit of plastic" — until you add it all up. Here's what a 3D print actually costs to produce, beyond the filament, and how to bring that number down.
The five components of print cost
A complete cost has five parts: 1) material, 2) electricity, 3) machine wear (depreciation), 4) a failure allowance, and 5) your labour. Skip any and you'll under-price.
1. Material
Material cost = (spool price ÷ spool weight) × grams used. Your slicer reports the grams. A cheaper spool isn't always better value if it weighs less — compare on cost-per-gram with the Cost-per-Gram Calculator. For resin, it's millilitres × price-per-ml (see the Resin Cost Calculator).
2. Electricity
A desktop FDM printer averages ~70–150 W while printing, mostly the heated bed. Energy (kWh) = watts ÷ 1000 × hours; cost = energy × your rate. It's small per print but real across a print farm — the Electricity Cost Calculator gives the exact figure.
3. Machine wear (depreciation)
Printers don't last forever. Spread the purchase price across its useful printing hours: depreciation = printer cost ÷ lifespan hours × this print's hours. On a $300 printer rated for 5,000 hours, a 6-hour print 'uses up' about $0.36 of machine.
4. Failed prints
Every failure wastes material, time, and electricity. If 8% of prints fail, your successful prints must each carry an 8% surcharge to stay whole. Pricing without a failure allowance is the quiet killer of maker-shop margins.
5. Labour
Setup, removal, support cleanup, sanding, painting, packing — all labour. Even at $15–20/hour, 15 minutes of hands-on work can exceed the material cost of a small print.
Worked example
An 80 g PLA print, 6 hours, on a $300 printer: ~$2.00 material + ~$0.12 electricity + ~$0.36 machine wear + 15 min labour at $20/hr ($5.00) = $7.48, plus an 8% failure allowance ≈ $8.08 all-in. The filament was only a quarter of it. Plug your own numbers into the 3D Print Cost Calculator.
How to cut cost
- Lower infill where strength allows — less material, faster prints.
- Cut failure rate (bed adhesion, dialed-in profiles) — this saves more than cheaper filament.
- Batch prints to amortise setup labour.
- Buy filament by cost-per-gram, not sticker price.
