3D Printing Cost Calculator

How Much Does a 3D Print Cost?

At home on an FDM printer, most prints cost between $1 and $30 in real terms. Using the calculator’s defaults — PLA at $25/kg, a 120 W printer bought for $300 with a 5,000-hour life, electricity at the April 2026 US average of 18.83¢/kWh, 10% material waste for supports, and a 10% failure buffer — here is what three common print sizes actually cost. A small 30 g print (a phone stand or desk hook, about 2.5 hours): $0.83 of filament, $0.06 of electricity, and $0.15 of printer wear — $1.15 after the failure adjustment. A medium 150 g print (a headphone mount or large vase, about 10 hours): $4.13 filament, $0.23 electricity, $0.60 depreciation — $5.50 all-in. A large 800 g print (a cosplay helmet split over roughly 48 hours): $22.00 filament, $1.08 electricity, $2.88 depreciation — $28.85 total. Notice the pattern: filament is roughly 80–85% of the cost at every size, which is why the spool price you enter matters more than any other field. Plug your own model weight and print time into the calculator above; slicers like Cura, PrusaSlicer, and Bambu Studio show both numbers on the preview screen before you print.

The Exact Formula Behind the Calculator

The calculator above computes: true cost = (material + electricity + depreciation) ÷ (1 − failure rate) + labor. Material is model weight in grams, multiplied by (1 + waste %) to cover supports, brims, and purge, divided by 1,000, times your spool price per kilogram. Electricity is printer wattage ÷ 1,000 × print hours × your rate per kWh. Depreciation is printer price ÷ expected lifetime hours × print hours — the default 5,000 hours is a reasonable service life for a consumer FDM machine before major repairs or replacement. The failure divisor is the piece most calculators skip. If 10% of your prints fail, every successful print has to absorb the material and time burned by the failures, so the subtotal is divided by 0.90 — an 11.1% surcharge, not 10%. At a 20% failure rate the surcharge jumps to 25%. Finally, the suggested sale price multiplies your true cost by (1 + markup %). Two worked micro-numbers you can reuse: a 120 W printer draws 0.12 kWh per hour, which costs about 2.3¢ at the 18.83¢/kWh US average, and a $300 printer over 5,000 hours adds exactly 6¢ per print hour.

Filament and Resin Prices in 2026

Spool prices as of July 2026: PLA runs $15–$30 for a 1 kg spool in the US, with budget brands (Sunlu, Elegoo, Overture) dipping to $10–$15 on sale and premium lines like Prusament at $29–$37. PETG runs about $14–$40/kg, ABS $12–$30/kg, and TPU $18–$50/kg, with most flexible spools landing at $35–$50. Specialty filaments — carbon-fiber blends, wood-fill, silk — typically cost $30–$50/kg. On the resin side, standard 405 nm resin from Elegoo or Anycubic costs $20–$35 per liter, specialty formulations (ABS-like, flexible, high-temp) run $28 to over $100/L, and closed-ecosystem resins like Formlabs run about $79–$299/L depending on printer generation and material (Form 4 standard resins start at $79/L; legacy Form 3 resins still run $149/L). The calculator’s $25/kg PLA default equals 2.5 cents per gram — a convenient mental benchmark. Two buying notes worth money: identical spools can vary 2–3× in price across retailers, so check at least two stores before restocking, and per-kg prices drop sharply on multi-spool bundles if you print more than a spool a month. Enter the price you actually paid, including shipping, in the calculator above — a $19 spool versus a $30 spool changes a 150 g print’s material cost from $3.14 to $4.95.

The Costs People Forget: Electricity, Wear, and Failures

Four costs rarely make it into hobbyists’ math. Electricity is the smallest: a typical FDM printer averages about 120 W while running (heaters cycle on and off), which is 0.12 kWh — about 2.3¢ per hour at the April 2026 US average rate of 18.83¢/kWh. Even a 48-hour print costs only about $1.08 in power, though enclosed high-temp machines and resin setups with wash-and-cure stations draw more. Depreciation is bigger than most expect: a $300 printer spread over 5,000 print hours costs 6¢ per hour, and a $1,200 machine costs 24¢ per hour — on a 10-hour print that is $2.40, often more than half the filament cost. Failed prints are the silent tax; if one print in ten fails, everything you make costs 11.1% more, which is why the calculator divides by (1 − failure rate) instead of pretending every job succeeds. Finally, consumables: brass nozzles cost a few dollars but wear out fast with abrasive filaments, hardened steel replacements run $15–$25, and PEI build plates cost roughly $15–$40. Budgeting a small maintenance reserve per print hour — even a few cents — keeps a year of nozzles, belts, and plates from feeling like a surprise.

Home Printing vs. Print Services in 2026

Online print services in 2026 typically charge $0.10–$0.30 per gram for FDM parts plus a $3–$10 setup fee per part, so a 100 g part usually quotes at $13–$40 before shipping. Marketplace platforms like Craftcloud and Xometry return quotes from many workshops at once, JLC3DP advertises small parts from $0.30, and professionally printed prototypes in the 10–20 cm range commonly run $50–$300. Compare that with home costs from the calculator above: the same 150 g part that costs about $5.50 to print yourself will usually quote at $18–$55 through a service — roughly 3–10× more, because you are also paying for their labor, machines, quality control, and margin. That gap is the payback math for buying a printer: saving $15 per medium part means a $300 machine pays for itself in about 20 prints. Services still win in three cases: materials your printer can’t handle (SLS nylon, MJF, metal), parts bigger than your build volume, and one-off jobs where a $20 quote beats owning and maintaining a machine. For anything you will print more than a handful of times, home printing is dramatically cheaper per part.

Pricing 3D Prints for Sale

Use the markup field in the calculator above as your floor, not your final answer. Most small sellers price made-to-order prints at 2–3× true cost; below 2× there is usually nothing left after platform fees and your time. Start from the full cost — including the failure buffer and labor, since removing supports, sanding, and packing a print for 15 minutes at even $15/hour adds $3.75 to a part. Then subtract selling fees: on Etsy in 2026, that is a $0.20 listing fee, a 6.5% transaction fee on the order total including shipping, and US payment processing of 3% + $0.25 — roughly 10% of a typical sale before any advertising, and Offsite Ads take another 12–15% when they generate the order. Worked example: a 150 g print costing $5.50 plus $3.75 of labor is $9.25 all-in; at a 2.5× markup you would list near $23, of which Etsy’s mandatory fees take about $2.60. Also check what the same item already sells for — a formula tells you your floor, but the market sets your ceiling, and undercutting by pennies mostly just erodes everyone’s margin.
