Selling STL Files vs Selling Prints: The Math for 3D Designers
One printed sale is worth about four and a half downloads — and it sells to a different audience. Your own prices, worked out.
A $5 download on a marketplace that keeps 20% leaves you $4. A $28 printed phone stand sold on Etsy leaves about $18.73 after Etsy’s fees and the cost of having it made, checked and shipped for you. So one printed sale is worth nearly five downloads. The two also reach different people, which matters more than the ratio. Put your own prices in:
Sell the file
You keep per download
$4.00
And the buyer owns a copy they can print forever.
Sell the thing
Etsy fees−$3.11
Made, checked, packed, shipped out by us−$6.16
You keep per sale
$18.73
One printed sale leaves as much as 4.7 downloads.
The part the ratio leaves out
Files and prints are sold to two different audiences.
Who buys whichA file sells only to people who own a printer and want to run it. A finished product sells to everyone who wants the object.
What each one actually sells
- The buyer
- A file buyer owns a printer, has the filament, and will spend an evening slicing and cleaning up. A product buyer wants the thing on their desk this week and has never opened a slicer.
- What they get
- A file is a set of instructions. A product arrives finished: the right colour, magnets set and parts assembled if you ask, checked by a person before it left.
- After the sale
- A file sells once per person, forever. A product that breaks, gets gifted or gets noticed on a desk sells again.
- Personal touches
- A file cannot put the buyer’s name on it. A product built from a Studio template can, automatically, for every order.
- Your time
- Zero for both, once the file is up and the product is listed. We make, check, pack and ship every order, and fit and assemble it if you ask.
Sell both, and choose what stays print-only
Most designers who add printed products keep selling files. The download serves the makers in the audience, and the printed version serves everyone who asked “can I just buy one?” The two rarely compete, because a person with a printer was never going to pay $28 for something they can make.
The exception is licensing. If you sell a file with a commercial licence, your buyers can sell prints of it, and some will list against you on the same marketplaces. Plenty of designers keep one or two signature designs print-only for that reason, especially ones with fitted hardware or assembly, which a casual reseller will not bother to reproduce.
Where a printed product earns its price
The ratio moves with weight and print time: a small part carries a tiny make cost, and a large one takes a bigger share of the price. Our Make-Cost Index shows thirty-six everyday products priced live, and most cost under $10 to make. The products that sell best printed tend to be the ones a file buyer would find fiddly: multi-part designs, things with magnets or inserts, and anything personalised. Those are exactly the jobs we include in the price instead of billing separately.
FAQ
They sell to different people, so most designers do both. Per sale, a printed product usually leaves several times what a download does — at a $5 file on an 80% marketplace against a $28 Etsy product costing $6.16 to make, one printed sale equals about 4.7 downloads.
It varies by site. Cults3D, for example, pays designers 80% of the net price and keeps 20%. Put your own marketplace’s cut into the calculator above.
No. A production partner prints each order when it sells. With us that includes a person’s check, a remake if a print fails, and shipping under your name, with hardware fitting and assembly at $1 a part when you want them.
Rarely. People who own printers buy files; people who do not buy products. The overlap is small. If you sell commercial licences, consider keeping your best design print-only so resellers cannot undercut it.
Sell the file to makers. Sell the thing to everyone else.
