What wears out?
Parts that wear out or need replacing. These are our assumptions, based on common web shop prices. They are estimates, not measurements.
| Part | Indicative price | Replacement | Cost per year |
|---|---|---|---|
| Nozzle | €5 | twice a year | €10 |
| Build plate (PEI) | €35 | once a year | €35 |
| Belts and lubricant | €10 | once a year | €10 |
| Small parts (fan, hotend) | €10 | once a year | €10 |
Together about €65 per year.
Cost per hour depends on how much you print
| Usage | Print hours per year | Maintenance per hour |
|---|---|---|
| 5 hours per week | 260 h | €0.250 |
| 10 hours per week | 520 h | €0.125 |
| 20 hours per week | 1040 h | €0.063 |
| 40 hours per week | 2080 h | €0.031 |
If you print little, the same costs are spread over fewer hours. The calculator default, €0.10 per hour, corresponds to about 13 hours per week. See also cost per print hour.
Tips to keep maintenance down
- Clean the nozzle and the build plate regularly.
- Use a hardened nozzle for abrasive materials such as carbon fiber filament.
- Keep spare parts you often need, so your printer is never idle.
Frequently asked questions
What does 3D printer maintenance cost per hour?
At about 10 print hours per week it is €0.13 per print hour by our assumptions. The more you print, the lower the cost per hour.
How often should I replace a nozzle?
Often every 6 to 12 months, depending on your use and the filament. Abrasive materials such as carbon fiber filament wear a brass nozzle faster.
How often should I replace the build plate?
A PEI plate often lasts about a year, depending on your use and cleaning habits.
Why does the calculator use €0.10 per hour?
That corresponds to a usage of about 13 hours per week by these assumptions. If you print more or less, adjust the amount.
