"I have that are on the go a lot of the time. I use them to make everything from replacement car parts to signs, and I even print material for local businesses. What's even better, I can print both when I'm physically there with the printers or remotely (yes, I can send projects to print from my iPhone -- what a time we live in!)."
"And because of this convenience of remote printing, I got into the habit of leaving everything on. Not all the time, but a lot of the time. After all, it's convenient. And the times I did turn them off, I got annoyed because I couldn't use them remotely. And because each printer has different filaments and capabilities, I couldn't just keep one on. I needed all three to be on."
"Then, one day, I was ideally thinking about power consumption of random household and workshop devices, and my eye shifted to my 3D printers. I mean, these things have lights and motors and heaters inside. They had to use a reasonable amount of power when they're making stuff, but what about when they're just sitting there doing nothing? I pulled out my power meter and decided to investigate. What I discovered wasn't bad, but it wasn't great either."
Remote-capable 3D printers are frequently left powered on for convenience, creating continuous standby energy use. Three printers used for fabrication and remote printing were examined with a power meter and each showed about 50W of standby draw. Standby consumption across multiple machines, accumulated over hours and days, can add noticeably to electricity bills. Investigating device consumption revealed neither catastrophic nor negligible waste, prompting consideration of remote-controllable power solutions. A Tapo smart power strip provides per-outlet monitoring and remote switching to eliminate standby draw. The power strip costs about $45 and can recoup its price through reduced energy waste.
