300 X 300mm (Approx. 12" X 12") 120V 750W, KEENOVO Universal Flexible Silicone Heater Mat/Pad, 3D Printer Heated Bed Heating Element

This thing is insane, I'm convinced it could boil a pot of water faster than my stove if I wanted. Heated the bed of my FT5 to 100C in 3 mins and holds temperature very well in pwm mode with the recommended SSR. When autotuning the PID controller my controller threw a warning that my heater was overpowered and calculated a max peak temp of over 350 deg C was possible. Installation was easy, the pad came with 3M adhesive applied so all I needed was a clean bed to stick it to. I used my old 12v bed heater cables as an input to the SSR and then sacrificed an old power cord and wired it into the load side. It just needs to be in the 120v circuit, same as a switch and polarity doesn't matter with that. I'll definitely recommend this for an upgrade to any large printer

i am happy using it in my 3d printer, works very fast and the seller send it in time, even with a pretty ornament additional. I am happy and satisfied, looking forward to buy againfrom them if i build another 3d printer.

The item arrived 5 days before the estimated delivery time. I have just mounted it with the basalt table. I have tested one time with a solid state relay controlling the input voltage and manual control of the relay. I do not have it working controlled with a rumba control board but the heat rise was at a satisfactory rate. This will be used with a mpcnc project and either the diamond 3 filament nozzle or a clone e3d single nozzle. This is an ongoing project which I work 0n as time permits so I expect that it will be some time before everything is working.

This thing works incredibly well. The bed of my printer is a pretty hefty chunk of aluminum (RailCore II 300ZL). This thing gets the bed up to temp (even 85°C) within a couple of minutes.It’s built sturdily and works well - what more can you ask for?

The pad came in sooner than expected.It was packed well and showed no signs of a bad trip.The pad is well made and cables are suficiently long.I’m using this on my FT5 and it stuck very well to the bottom of the alum bed. I just cleaned the surface with alcohol and used a roller to press the pad firmly Into my existing one.Using a SSR and 255 (full current) on the firmware it heats up to 80c stupid fast. 120c in less than 2mins.It is a great upgrade from that 12v bed.Would highly recommend it!

Product arrived many days AHEAD of expected delivery date. Product DOES ship from china, got my package in less than 7 days. A significant upgrade to any printer using a reprap "aluminum bed". Must use a Solid State Relay if you are running a DC voltage.The product heats the milled aluminum bed quickly, and it maintains temperature without fluctuation.

Using it on a Folger Tech FT-5, and it works great. Heats up incredibly quickly and I had no trouble setting it up. I've been using it for polycarbonate at about 150 C, and it seems like it can easily go hotter.

Heats to 80c in under 90 seconds and holds the temp with no variance at all. Be aware this doesn't have holes for print bed mounts l, and you can't just drill holes in it.
