How to Price 3D Prints on Etsy and Online Marketplaces
Undercutting on price is tempting but dangerous. Here is a repeatable method for calculating a floor price — and how to position above it without losing sales.
Selling 3D prints on Etsy or similar marketplaces is genuinely viable, but most new sellers undercharge badly in the first few months. They price by gut feel or by copying the cheapest listing they can find. Neither works. Here is a structured approach that protects your margin from day one.
Start with your floor, not the market
A floor price is the minimum you can charge without losing money. Everything below it means you are subsidising your buyer's purchase. Work out your floor first, then look at the market to understand where to position above it.
Your floor has five components: material, electricity, machine depreciation, labour, and a failure buffer.
Material cost
Weigh a spool before and after a known print run to get your grams-per-print figure. Multiply by your cost-per-gram. Add 8–12 % for waste (support structures, purge lines, occasional stringing that goes in the bin). On a £20/kg PLA spool, your cost-per-gram is £0.02. A 50 g print costs £1.00 in raw material, or £1.08–1.12 with waste.
Electricity cost
Desktop FDM printers draw 80–300 W depending on machine and enclosure. For a 4-hour print on a 150 W machine at 24 p/kWh, your electricity cost is 150 × 4 × 0.24 / 1000 = £0.14. Small, but it compounds at volume.
Machine depreciation
Divide machine purchase price by expected lifespan in hours. A £600 printer with a 3,000-hour lifespan costs £0.20 per print-hour. Add consumables — nozzles (£5–15, replaced every 200–400 hours), PEI sheets (£15–25, replaced every 500–1,000 prints), belts, PTFE — and you add roughly £0.05–0.15 per print-hour depending on your machine.
Labour
Even if it feels like you are not working, you are. Starting jobs, checking in, post-processing, packaging, and shipping a single print takes 20–40 minutes of real time. At £12/hour, that is £4–8 per print. This is often the largest single cost and the most ignored.
Failure buffer
If your printer fails 5 % of prints, roughly 1 in 20 runs costs you material and time with no revenue. Add a 5–10 % buffer to your cost base to account for it.
Putting it together
For a 50 g, 4-hour print: material £1.10 + electricity £0.14 + machine £1.00 + labour £5.00 + 8 % failure buffer = roughly £7.85 floor. If the market rate is £9–12 for that item, you have margin. If the market rate is £6, you need to either reduce cost (faster machine, cheaper filament, batching) or find a different product.
Positioning above the floor
Speed, reliability, and presentation let you price above commodity. Better photos, faster dispatch, consistent quality, and material options (PETG, wood fill, silk) all justify higher prices. Marketplaces reward social proof — reviews matter more than being the cheapest listing.
