How Do You Actually Price Your 3D Prints?

If you've ever tried selling a 3D-printed model, you've probably faced the same question: How much should I charge?

It's tempting to look at the amount of filament used, multiply it by the price per gram, and add a small markup. But that can leave out many of the costs involved in producing a print.

A better approach is to think beyond the spool.

Filament is the easiest part to calculate. If a print uses 150g of PLA and your filament costs $20 per kilogram, the material cost is about $3.

But that $3 is only the starting point.

Different materials also come with different costs. PLA, PETG, TPU, and more specialized materials such as carbon-fiber-filled filaments can have significantly different prices. Support material, purge waste, and leftover filament should also be considered when calculating the real material cost.

A printer running for 15 hours is still using electricity and occupying your machine, even if you aren’t actively watching it.

You can estimate an hourly machine cost that includes electricity, maintenance, nozzle and build-plate wear, and eventually the cost of replacing the printer itself.

For example, a simple formula could be:

This gives you a much more realistic starting point than filament cost alone.

Preparing a model, slicing it, checking supports, changing filament, removing the print, cleaning it up, and packaging it all take time.

A print that takes 20 minutes of hands-on work shouldn't be priced the same as one that comes straight off the printer with almost no finishing required.

If you're selling prints regularly, consider setting an hourly labor rate for your own time and adding it to the calculation.

Not every print makes it to the finish line.

Warping, layer shifts, adhesion problems, filament issues, or a simple mistake in the slicer can turn a 10-hour print into a box of scrap.

That doesn't mean every customer should pay for every failed print individually. Instead, build a small failure allowance into your overall pricing.

For example, if roughly 10% of your prints require a reprint, your pricing needs to leave enough room to absorb that loss.

This is where things get interesting.

Two objects can use exactly the same amount of filament but have completely different values.

A simple phone stand might take 100g of PLA, while a highly detailed custom part might use the same amount of material but require hours of modeling, testing, and finishing.

You're not only selling plastic.

You're selling the finished product, the design, the customization, and the time saved by the customer.

A custom-designed replacement part, for example, can be worth considerably more than its material cost simply because it solves a problem that would otherwise be difficult or expensive to solve.

For many small print businesses and hobby sellers, a practical starting point is:

The exact numbers will vary depending on your printer, location, material, print quality, and customer.

The important part is not finding one “correct” price. It’s making sure your price covers the real cost of producing the print and leaves room for profit.

Because if your calculation only asks, “How much filament did I use?”, you might be selling a 12-hour print for the price of a spool—and wondering why 3D printing never seems to make money.
