How print time cost is calculated
Energy is hours × watts ÷ 1000 kWh, multiplied by your electricity rate. Machine amortization spreads the printer's purchase price over its expected lifetime hours: price ÷ lifetime × print hours. Together they are the non-material cost of the print — add filament cost for the full picture, or jump straight to pricing your prints if you sell them.
Frequently asked questions
How many watts does a 3D printer actually use?
A typical bedslinger averages roughly 100–200 W once up to temperature, which is why the default is 150 W. The heated bed spikes well above that during heat-up, so for an exact figure measure a full print with a plug-in power meter.
How much electricity does a 10-hour print use?
At a 150 W average: 10 h × 150 W ÷ 1000 = 1.5 kWh, which is €0.45 at €0.30 per kWh. Electricity is rarely the dominant cost of a print — material and your time usually outweigh it. Omni-style time calculators omit electricity AND machine wear entirely; this tool prices both.
What is machine amortization?
The printer’s purchase price spread over its expected lifetime in print hours: price ÷ lifetime = cost per hour. A €300 printer rated for 2000 hours adds €0.15 to every print hour.
Where do I find my electricity rate?
On your utility bill, in EUR per kWh. If your tariff varies by time of day, use the rate for the hours the printer usually runs.
