If you don’t believe it, calculate it yourself
To calculate the amount of power used by your 3D printer, the best thing to do is to check your electricity consumption in kWh for every hour of the day. You will get an idea of how it goes up when you use your printer.
If an approximate idea is not enough, there are two much more precise ways of knowing how much power your 3D printer uses. A hard way and an easy way.
You are going to struggle with the hard way if you are more a person of letters. You must look at the leaflet to see the technical specifications for your printer model. You need to find the current value and multiply this by your household’s voltage (normally 220 volts) The result of this multiplication is the power in watts. To find out how much power you use, you have to multiply these watts by the hours in which the printer is working and, lastly, divide this by 1,000. This will give you the kWh that end up on your bill.
The easy option to find out exactly how many kWh your 3D printer uses, is to to install a power consumption meter, which will give you its consumption. You will also be able to switch it on and off remotely from your mobile phone.
Use your imagination
Now you know how much electricity your 3D printer uses each hour. However, remember that, obviously, the cost generated will be more or less, depending on the printing time.
There’s a big difference between making a shower curtain ring and making a 15-kg dumbbell. The more you make it work, the more power it will use.
