- FYSETC 2pcs 3D Printer Insulation Heated Bed Lightweight Foam Foil: 12" x 12" x 0.3" CR10 Build Plate Insulation Mat Self-Adhesive Hotbed Thermal Pad for CR-10/ 10S/ Ender 3 Max Reprap Taz6-300mm

Sheet works great, adhesive is super sticky. Make sure you know where you want it BEFORE trying to apply it. Definitely a single use item, not a even slight chance of reusing it. Cut heat up time by about 20 mins and help stabilize the temp. Total side note, my heat bed PCB shorted out (unrelated to the foam being installed) and actually charred the board. The smell was quite bad. But the insulation did not catch fire. It was also a little charred too but the foil lining was undamaged. So I can attest to it being somewhat non-flammable.

I originally wrote this review saying it was too thick and would hit the screws on a CR10S Pro. However, I didn’t realize at the time that the screws on the plate below actually move with the bed so it is not an issue. This product is super sticky and seems to work great. To be up front, I don’t know if it heats any faster and had not timed it. It does seem slightly faster but it’s not life altering. I would buy this again and plan to use it on my second printer. As a side note, remember this is a two pack. I didn’t realize that and ordered two for both of my printers. Thanks

Comes with 2 pieces, the extra sheet might be good for another 3D printer. Cuts easily, but like the other reviewers mention, the aluminum edges are sharp. Thanks to those reviews, I avoided cutting my fingers by being careful. I have protected myself from future injury by covering the aluminum (especially the sides) with Kapton tape, that works really well. You might want to relocate the heated bed's LED light like I did, so you can tell whether the temperature controller is cycling at the set temperature. I used silicon insulated thin wire, and since I had Kapton tape on top of the aluminum reflective barrier, the LED didn't need to be further electrically insulated from shorting out. Just a 1/2" slit was needed at each corner to provide fit around the adjusting screws. The Anycubic heater with glass Ultrabase heats up much higher in temperature, from a previous max of 93C to well over 105C, and does so about twice as fast as before. This, along with leveling the bed, allowed me to prevent curl on my ABS parts.

I tried to find and order these ones for work. I got different brand ordered through work, and they were horrible by comparison to these. The foam would literally fall apart when removing a section. This one will predictably tear, as needed to clear certain areas. Definitely an affordabe upgrade to unsulate your heated bed. Doesn't weigh much at all. Do it, and reduce your heatup and power on cycle times for your heated beds. This seems of good quality for what it is.

Sticks well. Easy to cut for a perfect fit. Keeps in the heat for more consistent and steady bed heat, which results in better print adhesion. It's kind of thick, so make sure you have room under your print bed.

Falls apart when cut. Looks like crap under my printer, bit works ok. I think kepton tape and some foam that came in the box would work better.

This helped a lot evening out the temp on my cheap 3d ended printer. Just cut to size and apply. Super sticky.

Using the bottom of my heated 3D printer bed, helps keep the temp more stable and easy to install, required slight trimming but no big deal
