The price of a 3D print is rarely a single number — it depends on several things working together. Once you understand what drives the cost, you can make smarter decisions and often get a cheaper part without compromising on what actually matters. Here are the most important factors.
Material usage and weight
The more plastic that's used, the more the part costs. A large, solid part costs more than a small or hollow one. The material itself matters too — simple materials like PLA are cheaper than technical materials with special properties. To compare, see our materials guide.
Print time
3D printing takes time, and time is a large part of the cost. A tall, detailed part with thin layers takes longer than a low, simple one. More height means more layers — and more layers means more time in the printer.
Infill
Most parts aren't solid inside but have an internal pattern called infill. Low infill saves material and time; high infill makes a stronger part but costs more. For many parts a moderate infill is plenty, keeping the price down without losing function.
Support material
Overhangs often need support that's printed along with the part and then removed. Supports cost both material and time, and can also require manual cleanup. A well-thought-out orientation or a small design tweak can sometimes remove the need entirely.
Post-processing
A part straight from the printer has visible layer lines. If you want sanded, glued, primed or painted surfaces, that's extra work — often by hand. It raises the price, but is sometimes worth it for the part's look or function. Read more about what's involved under post-processing.
Size and quantity
Large parts take more space, material and time. At the same time, the per-unit price often drops when you order several copies, since we can fill the build volume and handle the batch efficiently. If you need ten parts instead of one, each part is usually cheaper.
How to keep the cost down
A few practical tips:
- Make the part hollow if it doesn't need to be solid.
- Choose the right material — don't pay for properties you don't need.
- Avoid unnecessary supports through smart orientation or design.
- Order in batches if you know you'll need several.
The best way to know what your specific part costs is to try. Upload your model and get a quote right away — you'll see the price and can adjust the settings to fit your budget.
