Prusa Mini+ Power Usage  

Power usage (watts/hour) for PLA, PETG and ABS

Forgot to add, that's power usage (watts/hour)  for PLA, PETG and ABS.

Prusa Mini+ Power Usage

Hooked it on power meter some time ago ... cca 100W/h was average.

Power consumption

here is my printer's power usage with PLA printing at 210F/60F.

My theory on the slope of the first print (that was a 17 hour, overnight print) is that the room got warmer as it became day from night and the bed and hot end were not powered as long as when it was cooler.

Use Correct Units

Hi,

I'm trying to find out what the power usage (watts/hour) of the Mini+?

 

Cheers

Sorry to be the units police but this graph from @chvvkumar is the correct way to describe power. Power is in watts. Watts/Hour is not a a correct unit. Energy is in Watt hours. My engineering professors would give zero points if the units were wrong. I took that to heart.

Power usage will vary depending on room temperature and filament usage, and of course on temperatures.

PLA power consumption

For PLA when its heating up, was around 100-150w/h, then printing pla at 210c, was around 40-50w/h

• So printing at 50w/h 24h a day, would be 1.2kw/h

RE:

Think of it this way: mph (or kph) is a rate. Watts are a rate.

If you want to know how much energy you used for a print, and you know how long the print took, and what the watts are (from the handy plot above) then that's like finding how many miles (or km's) you drove.

Take the rate * the time, and get the unit of interest:

In a car, 60 mph * 1.5 hours, means you traveled 90 miles.

in the printer case, 75 watts * 24 hours = 1800 watt hours. divide by 1000 to get 1.8 kwh.

Hope that makes it clear. You will likely find that for most prints electricity is negligible compared to material cost.
