How to Price 3D Prints: What a $2 Print Really Costs

To price a 3D print, add up six costs — material, electricity, printer wear, failed prints, your hands-on time and packaging — then divide the total by one minus the margin you want. Here is why the filament you see in the slicer is only a small part of that, worked through one print.

Picture a maker — call her Rae, a composite of the print-shop owners the workbook below was built for rather than a real person — standing next to her printer on a Tuesday night. A customer has messaged: “How much for the articulated dragon in the teal silk?”

Rae opens the slicer. Nine hours, 85 grams. A 1 kg spool cost her $22, so the dragon is about $1.87 of filament. She doubles it, rounds up, adds a generous cushion for her trouble, and types “$12, shipped in a week.” It feels generous. The customer says yes in under a minute.

That fast yes is the first clue something is wrong.

Pricing a 3D print means adding up six costs, not one: the material, the electricity, the wear on the printer, the prints that fail, your own hands-on time, and the packaging. Then you set a margin on top. Filament is a small share of the total once any finishing is involved, which is why a price built from grams alone can land below cost without anyone noticing.

Adding up six costs for every model, and re-doing it every time a spool price changes, is exactly the part that gets abandoned. The 3D-Printing Shop’s Filament & Print-Cost Workbook does that part — grams, hours and your rates in, a true cost and a suggested price out, across your whole catalog. But the method is what matters, so here it is in full, worked through Rae’s dragon.

How to price a 3D print in six steps

This is the whole method. Every section below expands one step, using the dragon as the worked example.

1. Cost the material. Take the filament weight from your slicer, supports and purge included, and multiply it by your cost per gram.
2. Cost the electricity. Multiply the printer’s average power draw in kilowatts by the print hours and by your electricity rate per kWh.
3. Charge the machine rate. Divide the printer’s price minus its resale value by its expected lifetime print-hours, add a maintenance allowance per hour, and multiply that machine rate by the print hours.
4. Add a failed-print buffer. Divide the material, electricity and machine cost by your success rate as a decimal — 0.9 if 1 print in 10 fails — so the prints that work pay for the ones that don’t.
5. Add your labor and packaging. Multiply your hands-on minutes — slicing, setup, support removal, sanding, packing — by your hourly rate, then add packaging.
6. Set the price from a margin. Divide the total cost by one minus your target margin: a $15.46 cost (the dragon’s total, worked out below) at a 50% margin is $15.46 ÷ 0.5 = $30.92.

If you would rather fill in a sheet as you read, the free 3D Print Cost Starter is this method as a one-print worksheet.

The six costs inside every 3D print

Each cost has one input you look up and one you decide. Nothing here needs special software; it needs you to stop leaving five of the six at zero.

Steps 1 to 5 cost these six lines — step 5 covers both labor and packaging — and step 6 turns their total into a price.

Material is the easy one, with one trap: the number that matters is the slicer’s total, not the model’s weight. Supports, a brim and purge lines all consume filament that never ends up in the customer’s hands, so read the slicer’s figure after they are added.

Electricity is small but not zero, and it depends heavily on where you live. The US Energy Information Administration’s July 2026 Electric Power Monthly (PDF) (opens in new tab) put the average US residential price at 18.44 cents per kWh for May 2026, but the same table shows Hawaii at 52 cents. Use the rate on your own bill (if it is in cents, divide by 100 to get dollars). For the draw, use the printer’s average over a whole print, not the power supply’s rating on the label — a heated bed pulls hard while warming up and less once it holds temperature. A plug-in watt meter left on for one full print gives you the real figure.

The machine rate is the cost most easily left out. Your printer is slowly being used up, and every print-hour takes a slice of it. The machine rate is that slice: what the machine costs you per hour it runs. It is machine-hour cost with the electricity left out, because this method counts electricity on its own line. For its inputs, take resale value from used listings for the same model, use a conservative guess at lifetime print-hours that you revise as the printer ages, and set the maintenance allowance from what you spent on parts last year divided by the hours you printed.

The failure buffer exists because prints fail, and the filament, power and printer-hours spent on a failed print are gone. The buffer is material, electricity and machine rate added together, divided by your success rate, minus that sum. Log every failure for a month to find your real rate rather than guessing it.

Labor is your hands-on minutes multiplied by an hourly rate. Once a print needs finishing, it is often the biggest line on the sheet.

Packaging is what one pack-out costs you — box, fill, label — and it adds up fast across a year.

Worked example: the true cost of a 9-hour, 85 g print

Back to Rae’s Tuesday night. Here is the dragon costed honestly, one step at a time.

• Step 1, material: 85 g at $22 per 1 kg spool is 85 × $0.022 = $1.87.
• Step 2, electricity: an average draw of 120 W is 0.12 kW. Over 9 hours that is 1.08 kWh, and at $0.1844 per kWh that is $0.20.
• Step 3, machine rate: a $600 printer expected to sell for $100 when replaced, over 4,000 print-hours, is ($600 − $100) ÷ 4,000 = $0.125 per hour. Add a $0.10-per-hour maintenance allowance for nozzles, build plates and belts, and the machine rate is $0.225 per hour. Nine hours is $2.03.
• Step 4, failure buffer: material, electricity and machine rate so far total $4.10. If 1 print in 10 fails, the success rate is 0.9 — the successful 9 have to carry the tenth — so $4.10 ÷ 0.9 = $4.56. The buffer is the difference: $0.46.
• Step 5, labor: 10 minutes slicing and prepping the plate, 15 minutes removing supports, cleaning up the joints and test-flexing the articulation, and 5 minutes packing. Thirty minutes at $20 an hour is $10.00.
• Step 5, packaging: a small box, tissue and a label: $0.90.

Rae quoted $12. Every dragon she sells at that price costs her $3.46 — before any marketplace fee, payment processing or shipping, which would push the loss further. The fast yes was the customer recognizing a bargain.

Turning the cost into a price

This is step 6. The cost is the floor, not the price. A price has to leave a margin — the share of the price that is left once the cost is paid — to cover everything the per-print cost does not: design time, marketplace and payment fees, the slow months, the next printer.

To price from a target margin, divide the cost by one minus that margin:

• At a 40% margin: $15.46 ÷ 0.6 = $25.77
• At a 50% margin: $15.46 ÷ 0.5 = $30.92

Note what that is not: a 50% margin is not “cost plus 50%.” Cost plus 50% is $23.19, and at that price the margin is only a third. Margin and markup are easy to mix up, and the mix-up quietly turns a healthy-looking price into a thin one.

So Rae’s dragon, priced to pay her, is somewhere around $26 to $31, not $12. Whether the market will pay that for her dragon is a real question — but it is a different question, and she can only ask it once she knows the floor.

Why filament is a small share of what a print costs

Filament is 12% of the dragon’s true cost; labor is 65%. That ratio is why gram-based pricing fails: labor outweighs filament as soon as your hands-on minutes cost more than the grams do — for the dragon, anything past about six minutes at the bench.

The pattern is easy to see once you split the costs by who is doing the work:

• The printer’s side — material, electricity, machine rate and the failure buffer — came to $4.56 for nine hours of printing, about $0.51 per print-hour. Printing is cheap. That is the good news about the hobby.
• Rae’s side — labor and packaging — came to $10.90 for thirty minutes of her time. Her attention is the expensive part.

This is the turning point: the printer is not what you are selling. Your time is. The machine runs overnight for about fifty cents an hour. The half hour at the bench is what the customer is paying for, and it is the line that goes missing when a price starts from grams.

Batching is how you bring the labor line down

Because labor is the biggest cost, the biggest savings come from spreading it. Split your labor into two kinds:

• Per-plate labor — slicing, bed prep, starting the print. It happens once however many parts are on the plate.
• Per-piece labor — support removal, cleanup, packing. It happens for every part.

If Rae prints four dragons on one plate, the 10 minutes of prep is shared four ways — 2.5 minutes each — while the 20 minutes of cleanup and packing stays per dragon. Labor per dragon drops from 30 minutes to 22.5, or from $10.00 to $7.50. The print gets no cheaper to run; she gets cheaper to employ.

That is also why a one-off custom print should cost more than a catalog item. A one-off carries its whole setup alone, and often design and test-print time on top.

The pricing shortcuts that undercharge

Quick pricing rules anchored on the filament undercharge whenever labor is a big line. Here are three typical shortcuts, run on the same dragon.

Every one of them is below cost, and none of them is obviously silly. They feel reasonable because they start from the only number the slicer hands you. The fix is not a better multiplier — no single multiplier on grams can know how long this model takes to clean up. The fix is to cost the six lines.

The same trap runs through every craft, not only printing — how to price handmade goods walks through why the time line is the one that goes missing. And if you sell in person, the craft fair pricing mistakes that cost the most at a booth apply to a table of prints too.

Can you sell 3D prints of models you downloaded?

Only if the model’s license allows commercial use, or you have the designer’s written permission. Pricing a print correctly means nothing if you did not have the right to sell it.

Many free models on the big sharing sites are published under a Creative Commons license, and the version to watch for is NonCommercial — marked NC. The Creative Commons Attribution-NonCommercial 4.0 license (opens in new tab) states plainly: “You may not use the material for commercial purposes.” Selling a print is a commercial purpose.

Three practical rules:

• Read the license on every model before you list it, not after it sells. Record it next to the model in your catalog.
• “Free to download” is not “free to sell.” They are different permissions.
• Some designers sell commercial licenses or run a paid membership that includes selling rights. Where they do, that cost is part of your per-print price too — spread it across the prints you expect to sell.

Common questions about pricing 3D prints

How much should I charge per hour of 3D printing?

Charge for the printer’s own hourly cost — its machine rate plus electricity — and charge for your hands-on time separately at a real wage. In the worked example, the printer’s side came to about $0.51 per print-hour including a failure buffer, while Rae’s half hour at the bench cost $10.00. Blending the two into one “per hour” rate hides the expensive part.

How do I calculate the electricity cost of a 3D print?

Multiply the printer’s average power draw in kilowatts by the print time in hours, then by your electricity rate per kWh from your bill. A 120 W average over 9 hours is 1.08 kWh; at $0.1844 per kWh, that is about 20 cents.

Should I charge for failed prints?

Yes, but not to the customer who didn’t cause them. Build your failure rate into every price as a buffer, so the successful prints carry the cost of the ones that end up in the scrap bin. Log your failures for a month to find your real rate instead of guessing.

Can I sell 3D prints of models I downloaded?

Only if the model’s license allows commercial use, or you have the designer’s written permission. Models marked NonCommercial (NC) under Creative Commons cannot be sold as prints under that license alone.

Price the catalog once, not every print

Rae’s mistake was not bad math. It was doing the math from memory at 10 p.m. with a customer waiting, which is when every shortcut above feels reasonable.

The fix is to cost each model once, write it down, and let the price update when a spool price or your wage changes. The 3D-Printing Shop’s Filament & Print-Cost Workbook was built for exactly that: a true print-cost calculator, a machine rate for every printer you own, a filament inventory that flags a spool before it runs dry mid-print, a failed-print log that records what every failure cost, so a month of it tells you your real failure rate, and a per-model catalog that re-prices everything when one assumption moves.

And when the print shop outgrows a spreadsheet — more printers, more channels, orders you need to track from queue to shipped — Ardent Seller (opens in new tab) is the next step.
