At some point most people who 3D print think about selling their prints. You're making things anyway, you have the equipment, the designs are your own — why not turn it into something?
We went through this thought process with kite badges. We designed them ourselves, printed them, liked how they turned out, and started looking at whether selling them on Etsy made sense. We ran the numbers. The short version is: it didn't, at least not at the price point where anyone would actually buy them.
Here's what the calculation looked like and what we learned from it.
The product — kite badges
The badges were custom designed — kite-shaped, printed flat with a clean finish, the kind of thing you'd attach to a bag or a jacket. We were happy with the design and the print quality. They looked good. That part wasn't the problem.
The problem was everything that happens between "the print looks good" and "money arrives in your account."
Breaking down the costs
Let's work through what it actually costs to sell a 3D printed item on Etsy.
Materials — filament cost per badge, based on weight. A small badge might use 5–10 grams of filament. At typical PLA prices that's a very small amount — maybe 10–20p per badge in raw material. So far so good.
Print time — printers aren't free to run. Electricity costs something. Wear on the machine costs something. More importantly, your time costs something — setting up the print, removing the finished pieces, checking quality, packing failed prints aside. Even if you don't value your time highly, it's not zero.
Etsy listing fee — Etsy charges $0.20 (roughly 16p) to list an item, renewable every four months or when it sells.
Etsy transaction fee — 6.5% of the sale price including any shipping you charge.
Etsy payment processing — around 4% plus a fixed fee per transaction, depending on your country.
Packaging and postage — a padded envelope, a small card, tissue paper if you want it to look nice. Then the actual postage. For a small item going Royal Mail second class in the UK, that's over £1 even for the lightest option. International postage is considerably more.
Offcuts and failed prints — not every print is sellable. Stringing, a slight warp, a layer shift. Those failed prints cost filament and time and you get nothing back for them.
What this means for pricing
Add all of that up and you quickly arrive at a minimum price you need to charge just to break even. For a small badge, that number was higher than we expected — and the break-even price was already at the top of what similar items sell for on Etsy.
Etsy buyers are price-sensitive and the market for 3D printed items is competitive. There are sellers printing at volume who can absorb lower margins because they're running prints continuously at scale. For a small operation printing one-offs or small batches, competing on price with high-volume sellers is very difficult.
The margin left after all costs was small enough that we decided it wasn't worth pursuing. A few sales wouldn't cover the time spent setting up the shop, photographing the items, writing listings, handling messages, and packing orders. It would have been a lot of work for not much return.
What would make it work
That said, plenty of people do make money selling 3D prints on Etsy. The ones who tend to do well share a few characteristics:
- High-value items — larger, more complex prints that justify a higher price point. A detailed miniature, a custom prop, a functional product. These take longer to print but the higher price means the fixed costs (fees, postage, packaging) are a smaller percentage.
- Unique designs — items you can't easily buy elsewhere. Generic prints compete on price. Something genuinely original commands a premium.
- Digital files — selling the STL file rather than the physical print removes postage, packaging, and print time from the equation entirely. Your only cost is the time to design the file and list it. This is how many successful Etsy sellers in the 3D printing space actually make money.
- Volume — printing the same item many times spreads setup time across more units. A print farm running the same badge fifty times is a different economics problem from printing five.
What we took from it
Running the numbers before committing time to a shop was the right call. It's easy to assume that because making something is enjoyable and the cost of materials is low, selling it will be profitable. The fees, postage, and time add up faster than you expect.
The kite badges were a good design exercise and we learned something useful about what it actually takes to sell physical goods online. The prints themselves still exist. They just live here rather than on someone else's jacket.
If you're thinking about selling 3D prints, the honest advice is: do the numbers before you open the shop. Include your time, include every fee, include postage and packaging, and include a realistic failure rate. Then decide whether what's left is worth it.
