01 Resin and supports
Use the slicer’s total volume for the plate, including supports and rafts, then divide by usable finished units.
SELLER PRICING GUIDE
How much should you charge for resin 3D prints?
A sustainable price covers more than resin. It pays for failures, equipment, post-processing, packaging, selling fees and your time—then leaves an intentional profit.
Calculate the full cost of producing one successful unit, add every selling cost, and work backwards from your target margin. Then compare the result with what customers will realistically pay. If the market price is below your required price, improve the product or process instead of quietly deleting labour and wear from the calculation.

Your selling price needs to absorb percentage fees and profit margin as well as fixed costs. Simply adding a percentage to resin cost will usually underprice the work.
fixed unit costs = production cost + packaging + postage + fixed selling fees
target item price = adjusted fixed costs ÷ (1 − percentage fees − target margin)
Shipping charged to the buyer can change the algebra because some marketplaces also charge percentage fees on shipping. ResinMetrics accounts for this separately.
What belongs in your production cost?
02 Failure allowance
Failed attempts consume material and time. Use your measured plate failure rate rather than assuming every run succeeds.
03 Machine and screen wear
Allocate equipment and replaceable-screen cost across editable useful-life assumptions.
04 Consumables
Include washing liquid, gloves, filters, towels, release-film wear and other repeated workshop supplies.
05 Hands-on labour
Count preparation, washing, support removal, curing, inspection and cleanup—not unattended print time as though it were labour.
06 Replacements and breakage
If delicate prints regularly break during finishing or shipping, those replacements are part of the product’s economics.
Worked pricing example
Suppose one finished model has a true production cost of £4.50. Packaging costs £0.75, postage costs £3.50, the fixed transaction charge is £0.25, percentage fees are 10%, and the buyer pays £3.50 shipping. To keep a 40% margin on the item price:
| Pricing component | Example |
|---|---|
| Production cost | £4.50 |
| Packaging | £0.75 |
| Postage paid by seller | £3.50 |
| Fixed fee | £0.25 |
| Percentage fees | 10% |
| Target margin | 40% |
| Calculated item price | £11.70 |
| Buyer pays including shipping | £15.20 |
| Estimated profit | £4.68 |
This is an illustration, not a recommended market price. Change the fee structure, shipping treatment or target margin and the answer changes.
Margin is not markup
If an item costs £10 and you add a 50% markup, the price becomes £15 and the profit is £5. That £5 is only one third of the £15 selling price, so the margin is 33.3%—not 50%. Pricing from target margin solves the equation backwards.
Why charging only by resin volume fails
Two models using the same resin can have completely different economics. One may print ten at a time with easy supports; another may occupy most of the plate, take longer to clean and break during shipping. Volume-only pricing ignores those differences.
Should you charge for print hours?
Machine time has a cost, but a universal hourly selling rate is crude for resin printing. Ten miniatures can share almost the same layer time as one miniature on the same plate. Allocate machine wear and electricity to the plate, then divide by successful units. Charge for the value and difficulty of the finished product—not merely elapsed hours.
Check commercial rights before selling
Buying or downloading an STL does not automatically grant permission to sell physical copies. Confirm the creator’s current commercial licence and the current rules of the marketplace you use. Keep evidence of the applicable licence and do not describe third-party designs as your own. This section is general information, not legal advice.
Market price still matters
A formula shows the price your business requires; it does not force buyers to accept it. Compare genuinely similar products, quality, scale, finish, durability, packaging and delivery. If the required price is uncompetitive, the useful response is to improve plate utilisation, reduce failures, shorten hands-on processing, create a stronger offer or choose a different product.
Five pricing mistakes to avoid
- Multiplying resin cost by an arbitrary number and calling the remainder profit.
- Treating unattended machine time as labour while ignoring actual cleanup time.
- Forgetting that percentage fees may apply to shipping as well as item price.
- Using a marketplace fee percentage copied from an old article instead of your account.
- Confusing revenue with profit when planning monthly capacity.
Use the complete resin printing cost guide to build production cost, the pricing calculator to solve for margin, and the print-farm calculator to test monthly capacity.
Frequently asked questions
How much should I charge for a resin 3D print?
There is no defensible universal rate. Start with complete production and selling costs, select a target margin, then compare the resulting price with the market.
Should I charge by resin volume or print time?
Use neither on its own. Calculate cost per successful unit after material, shared plate time, failures, wear, consumables and labour.
What margin should I use?
The right margin depends on demand, replacements, overhead, tax treatment and how much work the product creates. Test several scenarios instead of copying an arbitrary percentage.
Can I sell prints made from purchased STL files?
Only where the licence and selling platform permit it. Check the creator’s current commercial terms and keep evidence of the licence that applies.
