How much should I charge for 3D printing?

A fair 3D printing price has to cover more than filament. Your printer occupies production capacity, consumes electricity, wears out components, and sometimes produces a failed part. You may also spend time preparing the file, removing supports, finishing the surface, packing the order, and answering customer questions.

That does not mean every print needs a high price. It means the price should come from your actual costs instead of a guess, a filament multiplier, or somebody else's listing.

The short 3D printing pricing formula

Start with the complete direct cost of one successful sale:

Next, spread failed attempts across the successful work that pays for them:

Finally, recover selling fees and leave the target share of revenue as profit:

Enter percentages as decimals in a manual formula: 8% becomes 0.08. Variable fees plus target margin must remain below 100%. MakerGauge performs that validation for you.

What belongs in your 3D print cost?

Material

Use the total material estimate from your slicer, including supports, brims, purge material, and prime towers where applicable. Calculate base filament cost as material grams multiplied by spool price per usable gram. Add a measured waste allowance when the slicer does not capture remnants, routine purge, or color-change waste.

Electricity

Use average measured power when possible. A printer's maximum rated wattage may be much higher than its average draw across a complete job.

Machine time

Machine time is not labor. A twelve-hour unattended print does not require twelve hours of wages, but it reserves the printer for twelve hours. A machine-hour rate can recover depreciation, replacement nozzles and build surfaces, routine maintenance, repairs, and downtime.

Hands-on labor

Count file preparation, printer setup, part removal, support removal, sanding, assembly, quality checks, customer-specific work, and packing. Record several real orders: memory tends to miss short tasks that repeat on every sale.

Selling and order costs

Include packaging, purchased design licenses, inserts, hardware, and seller-paid shipping. Marketplace fees deserve separate attention because percentage charges are based on revenue. Check current rates in the marketplace's official policy rather than copying an old estimate.

Worked example: a twelve-hour PLA print

Every number below is illustrative, not a market average:

• 240 g PLA from a $22.99 / 1,000 g spool
• 8% material waste allowance
• 12 print hours at 120 W and $0.18/kWh
• $0.65 machine rate per print hour
• 25 minutes of hands-on labor at $24/hour
• $1.25 packaging, 8% failure allowance
• 9.5% variable selling fees, $0.20 fixed fee
• 25% target gross margin; shipping paid separately by the buyer

Material:

Electricity, machine time, and labor:

Direct cost is $5.96 + $0.26 + $7.80 + $10.00 + $1.25 = $25.27. Applying the 8% failure allowance gives $25.27 ÷ 0.92 = $27.47.

The target-margin price is:

The seller could test approximately $42.25, then check whether customers see sufficient value. At that price, the entered fees are about $4.21 and estimated profit is about $10.57—close to the selected 25% margin after display rounding.

Margin is not markup

If an item costs $20 and you apply a 25% markup, the price becomes $25. Profit is $5, but $5 is only 20% of the $25 selling price. Markup compares profit with cost; margin compares profit with selling price. Choose one method and label it clearly.

Adjust the formula for the job

A repeat product may need only a few minutes of hands-on work. A custom commission may require design revisions, test prints, customer communication, and a commercial model license. Charge those costs to the job that creates them. In a batch, setup labor may be shared, while material, occupied machine time, fees, and per-item packaging still grow.

Before publishing a price, ask:

• Does the slicer total include purge and support material?
• Did I separate hands-on labor from unattended machine time?
• Is free shipping actually included in my cost?
• Are marketplace and payment fees current?
• Can the result absorb a remake, return, or unexpected repair?
• Does the customer still receive reasonable value?

A formula provides a defendable starting point, not a promise that demand exists. Final pricing should also reflect finish quality, turnaround time, design rights, differentiation, and the alternatives available to the customer.
