Understanding Prusa Research Original Prusa MINI+ Running Costs
How FDM affects the numbers
FDM machines draw power in bursts rather than continuously. The hotend and heated bed cycle on and off to hold temperature, so the average figure used here sits well below the peak nameplate rating — the bed is usually the single largest consumer, which is why enclosed and large-bed machines cost noticeably more per hour to run.
Power draw: 80 W
At under 100 W this machine consumes less power than a typical desktop computer. Electricity is effectively a rounding error in your quotes — at ordinary residential rates a full day of printing costs less than a cup of coffee. Depreciation and your own labor will dominate the true cost of every part.
What dominates the hourly rate
Depreciation is the larger share of this machine’s hourly rate, so the assumed lifespan drives your cost more than your electricity tariff does. If you service the machine well and expect to exceed the default hours, raise the lifespan figure in the calculator — it will lower your quoted cost more than any energy saving could.
Quoting at this price point
Mid-range machines are the sweet spot for small workshops, and their depreciation is usually the larger half of the hourly machine rate. At this price point reliability improves enough that the failure buffer in your quotes can reasonably drop toward the lower end of the 8–10% range — provided the machine is well maintained and running profiles you have actually validated.
Build volume: 5,832 cm³
The compact build envelope favors small, detailed parts and makes this machine well suited to batching many little components in a single job. Because the heated area is small, warm-up is quick and per-hour energy cost stays low — but larger parts will need splitting and joining, and that assembly time belongs in your labor estimate.

Frequently Asked Questions
How much electricity does the Prusa Research Original Prusa MINI+ use?
The Prusa Research Original Prusa MINI+ draws an average of 80 watts during active printing. At the standard residential electricity rate of $0.16 per kWh, running this printer costs approximately $0.013 per hour in power. A 10-hour print consumes ~0.80 kWh (about $0.13 in electricity).
What is the depreciation rate for the Prusa Research Original Prusa MINI+?
With a retail MSRP of $459 and an expected operational lifespan of 4,500 printing hours, the machine depreciation rate is $0.102 per operating hour. Including this in your print quotes ensures hardware replacement and maintenance costs are recovered.
What is the combined machine running cost per hour for the Prusa Research Original Prusa MINI+?
Combining power consumption ($0.013/hr) and equipment depreciation ($0.102/hr), the total baseline operating cost for the Prusa Research Original Prusa MINI+ is approximately $0.11 per hour (excluding raw filament/resin and operator labor).
Is electricity or depreciation the bigger cost on the Prusa Research Original Prusa MINI+?
Depreciation is the larger share of this machine’s hourly rate, so the assumed lifespan drives your cost more than your electricity tariff does. If you service the machine well and expect to exceed the default hours, raise the lifespan figure in the calculator — it will lower your quoted cost more than any energy saving could.
What should I know about running the Prusa Research Original Prusa MINI+ (FDM) commercially?
At under 100 W this machine consumes less power than a typical desktop computer. Electricity is effectively a rounding error in your quotes — at ordinary residential rates a full day of printing costs less than a cup of coffee. Depreciation and your own labor will dominate the true cost of every part. Mid-range machines are the sweet spot for small workshops, and their depreciation is usually the larger half of the hourly machine rate. At this price point reliability improves enough that the failure buffer in your quotes can reasonably drop toward the lower end of the 8–10% range — provided the machine is well maintained and running profiles you have actually validated.
How do I calculate commercial quotes for 3D prints on a Prusa Research Original Prusa MINI+?
To calculate a profitable quote: (1) calculate filament or resin consumed, (2) add machine operating cost ($0.11/hr × print time), (3) add labor preparation time, (4) apply an 8%–10% risk buffer for print failures, and (5) apply your target retail profit margin (typically 40%–60%).
Calculate maximum melt zone limits (mm³/s) to prevent underextrusion on high-speed prints.
