How to Price 3D Prints for Profit (Formula)

Most makers price 3D prints by guessing at filament cost and doubling it — then wonder why a 6-hour print earns less than minimum wage. Here's the actual formula for how to price 3D prints for profit, plus the seven inputs that separate a hobby from a business.

Why this matters

Filament is the cheapest part of a print and the easiest number to get right — which is exactly why it's the number most makers anchor on. A spool running $20 to $25 feels like the whole cost, so a print using $4 of filament gets listed at $12 and everyone calls it a 3x markup.

It isn't. That $12 print also ate 40 minutes of a printer that isn't free to run, plus the time you spent slicing, watching for failures, and packaging the thing. Undercharging on 3D prints doesn't show up as a loss on paper — it shows up as a business that never has cash for a second printer.

The steps

1. Weigh the print and price the material

Weigh the finished piece plus supports on a gram scale, then multiply by your cost per gram. A $22 spool of PLA holding 1,000 grams runs about $0.022/gram, so a 120-gram print costs roughly $2.64 in filament alone.

Resin printers run differently — a liter of standard resin costing $30-40 works out to $0.03-0.04/mL, and you're also burning through gloves, funnels, and cleaning alcohol every batch. Common mistake: pricing resin prints like FDM prints and forgetting the consumables.

2. Add machine time cost

Multiply your printer's wattage by hours run, convert to kWh, then multiply by your electricity rate. A 200W printer running 6 hours uses 1.2 kWh — at $0.16/kWh that's about $0.19 in electricity.

That number looks tiny, which is why people skip it. It's not the electricity that matters here — it's that the printer occupying 6 hours can't run a second job in that window, and that's real opportunity cost even on a hobby-scale operation.

3. Build in a failure buffer

Even dialed-in printers fail 10-20% of the time on complex geometry, according to widely cited maker community estimates for print farms. If one in five prints fails, your successful prints need to absorb the cost of the failed ones.

Divide your material and machine cost by 0.85 (accounting for a 15% failure rate) to spread that risk across every print you actually sell. Skip this step and a bad week of failed prints wipes out a month of margin.

4. Price your labor honestly

Labor isn't just print time — it's design or file prep, slicing, bed leveling, supports removal, sanding, and packaging. Fifteen minutes of hands-on work at a $20/hour rate you'd pay yourself adds $5 to the print, even though the printer did the printing.

Most makers price labor at zero because the printer is doing the printing. That's the mistake that keeps 3D printing a $200/month side hustle instead of a business.

5. Layer in overhead

Marketplace fees (Etsy runs roughly 6.5% transaction fee plus payment processing), packaging materials, and software subscriptions all belong in the cost stack. A $2 mailer box and $0.50 in bubble wrap on a $25 print is 10% of revenue before you've made a dollar of profit.

6. Apply your markup

Total your material, machine time, failure buffer, labor, and overhead into one cost-to-make number. A 3x markup on total cost is the standard baseline for print-on-demand style 3D printing; complex or custom commission work supports 4-5x.

On a print with $2.64 material, $0.19 electricity, 15% failure buffer, $5 labor, and $1 overhead — total cost lands near $10.50. At 3x, that's a $31.50 list price.

7. Sanity-check against the market

Search three to five comparable listings for size, detail level, and material before you publish your price. If your formula-based number sits 40% above every comparable, either your labor estimate is inflated or you're targeting the wrong buyer.
