How Much Does a 3D Print Cost?

What does a small 3D printed part really cost to make? For a 50 gram print on a home printer, the answer is about 1.41 in your local currency. That covers the plastic, the power, and a small cushion for prints that fail. This guide breaks that number into its parts, so you can price any print in under a minute.

3D Print Cost Quick Reference

The table below prices five print sizes with the same settings. Filament costs 25 per kg, the printer draws 200 watts, and power costs 0.15 per kWh. Each total includes a 5 percent failure allowance.

Notice the pattern down the columns. The filament cost grows with the grams, while power grows with the hours. In every row, the plastic costs far more than the electricity.

The numbers work in any currency. Enter dollars, pounds, or euros, and the results come out in that same currency.

To run your own figures instead of these defaults, the 3D printing cost calculator for filament, power, and failures fills in every column from your slicer numbers. Change one input at a time to see which one moves your total the most.

What Goes Into the Cost of a 3D Print?

A home print has three cash costs: the filament it uses, the electricity it draws, and an allowance for failed prints. Add the first two, then scale up by the allowance.

A federal study of additive manufacturing costs from NIST sorts these costs into two groups. Material, machine, and labor costs are easy to measure. Build failures and machine setup are harder to see, yet they still cost money. The same review found that material makes up a major share of what a printed part costs.

Six terms show up whenever people price a print. Here is what each one means.

Slicer Estimate

The grams of filament and the print time that your slicing software predicts before the print starts.

Infill

The inner fill pattern of a part, set as a percentage. More infill uses more grams and more time.

Supports

Extra plastic printed under overhangs, then snapped off and thrown away after the print.

Direct Cost

Filament cost plus electricity cost, before any allowance for failures.

Failure Allowance

A percentage added to the direct cost to cover prints that fail or get scrapped.

Kilowatt-Hour (kWh)

The unit on your power bill. One kWh is one kilowatt of power used for one hour.

How Do You Price the Filament for One Print?

Divide the grams by 1,000, then multiply by the price per kilogram. A 50 gram part from a spool that costs 25 per kg uses 1.25 of filament.

Another way to see it: 25 per kg works out to 0.025 per gram, or 2.5 hundredths of your currency for each gram. Once you know that per-gram rate, any slicer estimate turns into a cost almost instantly.

Take the grams from your slicer, not from the model’s volume alone. The slicer count includes supports, brims, and the purge line, and all of that plastic is paid for too. Our guide on how to calculate material waste and overage explains why planned scrap belongs in every material estimate.

Filament price changes the result in direct proportion. The same 50 gram part costs 1.00 at 20 per kg, 2.00 at 40 per kg, and 3.00 at 60 per kg. Specialty materials often cost more per kilogram, so check the price on your spool. Trimming infill and supports saves money too, since every gram saved cuts 0.025 at this spool price. For material cost on its own, the filament cost calculator handles just that step.

How Much Electricity Does a 3D Printer Use Per Print?

Multiply the printer’s power in kilowatts by the print hours to get kWh, then multiply by your price per kWh. A 200 watt printer running 3 hours uses 0.6 kWh.

At 0.15 per kWh, those 0.6 kWh cost 0.09. The math follows the same rule the EIA uses to define the kilowatt-hour. Our explainer on what a kWh is and how electricity units work covers the units in more depth.

Your local rate changes this line of the bill. The EIA reports a 2025 US average residential price of 17.30 cents per kWh. Across all customer types, 2025 state averages ranged from 8.20 cents in North Dakota to 35.72 cents in Hawaii.

The EIA also posts average prices for each state every month. Your own bill shows the exact rate you pay per kWh, and that is the best number to use.

Even at the highest rate, power costs only 0.21 for this print. Heated beds and enclosures raise the average draw, so check your machine’s rating. To price power by itself, try the 3D printer electricity cost calculator.

Why Add a Failure Allowance?

Some prints fail, and the plastic and power they used are gone. A failure allowance spreads that loss across your good prints, so each part carries its fair share.

Our calculator suggests an allowance of 3 to 10 percent. On the 1.34 direct cost, 3 percent adds 0.04 for a total of 1.38. The standard 5 percent adds 0.07 for 1.41, and 10 percent adds 0.13 for 1.47.

Pick the rate from your own history. A tall, thin model or a new material fails more often than a flat bracket. Keep a simple tally for a month, noting every print that went into the bin. That record tells you which percent to use.

What Does the Cash Cost Leave Out?

The 1.41 covers plastic, power, and failures only. It leaves out your time, printer wear, and spare parts, which matter as soon as you sell prints.

Labor is often the largest missing piece. Design work, setup, and removing supports all take time. Sanding and painting take even more. Put an hourly value on that time before you quote a price to a customer.

Wear adds up slowly but surely. Nozzles, build surfaces, and belts all need replacing over time. Divide each part’s cost by the print hours it lasts, then add that small charge to every hour of printing. For example, a 5 nozzle that lasts 500 hours adds 0.01 per hour, or 0.03 to a 3 hour print.

Use the cash cost as your floor, not your price. A print sold for 1.41 only pays for its materials, with nothing left for your time.
