How to Price 3D Prints: The Complete Guide

Most people who start selling 3D prints price the same way: weigh the part, multiply the grams by the price of a spool, maybe double it, and call it a day. It feels reasonable. It is also how you end up working for free.

Filament is usually the smallest real cost of a print. The electricity, the wear on your printer, the prints that fail at hour nine, the time you spend slicing, removing supports, and packing — none of that shows up on the scale. This guide walks through every cost that actually goes into a print, then shows you how to turn that into a price your customers will pay and your business can survive on.

The seven costs in every print

A defensible price starts by adding up what the print genuinely costs you:

1. Filament — grams used × price per gram. A 1 kg spool at $22 is $0.022/g, so a 40 g print uses about $0.88 of plastic.
2. Electricity — printer wattage × hours × your electricity rate. A Bambu A1 pulls roughly 100 W average during a print; a 6-hour job at $0.15/kWh is about 0.6 kWh, or $0.09. Small, but real.
3. Machine wear — nozzles, belts, hotends, build plates and the printer itself wear out. Estimate the printer's lifetime hours and divide its cost (plus consumables) across them. A few cents per hour adds up.
4. Failure buffer — some prints fail, and you eat that cost. If 1 in 10 prints fails, every successful print needs to carry roughly 10% extra to cover the loss.
5. Labor — the part nobody charges for and everybody resents later. Slicing, plate prep, support removal, sanding, QC and listing all take time. Pay yourself an hourly rate and count the minutes.
6. Packaging — mailer, bubble wrap, tape, thank-you card, label. Often $0.50–$2.00 per order, and easy to forget.
7. Design / licensing — if you bought or designed the model, amortize that cost across the number of copies you expect to sell.

Add those together and you have your true cost — the floor below which every sale loses money.

From cost to price: the margin

Your cost is not your price. On top of cost you add a margin — the profit that pays for your risk, your skill, and your time spent on everything that isn't a billable print (marketing, customer service, bookkeeping).

A simple, widely used approach is a cost multiplier:

• ×2 to ×3 for simple, single-color prints you make in volume.
• ×3 to ×4 for typical retail items sold on a marketplace.
• ×4 to ×5+ for multicolor (AMS) prints, custom/commissioned work, or anything requiring significant finishing.

So if a print truly costs you $4.50 to make, a ×3 multiplier gives a $13.50 price. The multiplier isn't magic — it's a fast way to bake in profit plus a cushion for the costs that are hard to pin down per-item.

Rule of thumb: if your price is only covering filament, you're not running a business — you're subsidizing a hobby.

A worked example

Say you're selling a small multicolor desk organizer:

• Filament: 85 g across two colors → $1.87
• Electricity: 5.5 hours at ~100 W, $0.15/kWh → $0.08
• Machine wear: 5.5 hours at $0.04/hr → $0.22
• Failure buffer: 12% of the above → $0.26
• Labor: 20 minutes at $15/hr → $5.00
• Packaging → $1.20

That's a true cost of about $8.63. The labor and packaging dwarf the filament — which is exactly the point. Apply a ×3 retail multiplier and you'd list it around $26. Price it at "filament × 2" instead and you'd charge under $4 and lose money on every single order.

Marketplace fees change the math

If you sell on Etsy, eBay or Amazon, the listed price is not what you keep. Between transaction fees, payment processing and listing costs, you can lose 10–15% off the top, before shipping. If you need to net $26, you have to list higher so the fees don't quietly erase your margin. Always price to your take-home, not the sticker.

Common mistakes that quietly kill margins

• Pricing by filament weight alone. It ignores 80% of your real costs.
• Not paying yourself for labor. Your time is the most expensive input — count it.
• Forgetting failed prints. A 10% failure rate is a 10% tax on every good print. Build it in.
• Ignoring marketplace fees. A "$25" sale on Etsy can net you $20.
• Racing competitors to the bottom. There's always someone pricing at a loss because they haven't done this math. Don't join them.

Make it automatic

You don't need a spreadsheet for every quote. The 3D Print Pricing Calculator adds up all seven costs above, applies your margin, accounts for failure rate and marketplace fees, and gives you a defensible price in seconds — so you can quote with confidence instead of guessing.
