Universal 120V Silicone Heater Pad Edge to Edge Heaters with Thermal Switch Protection AC Bed Heater

Excellent Product! Thank you for the effort.

This is an awesome product, and as far as I can tell exclusive to west3D. No matter what any youtube video says, you must heat the bed all the way to edges or your ABS/ASA parts will curl up there. Now that the bed is heated entirely and uniformly, I can utilize the full 250x250mm of my Trident 250. Before this upgrade I would have to think long and hard about printing a part larger than 220 x 220. I have even tried extended pre-heat times of over an hour on a printer that takes 15 minutes to get up to temp. Nothing works with difficult geometry, the heat is just sucked away too quickly at the edges. No matter what the Voron instructions say, or any hot shot on youtube, I highly recommend you heat your bed uniformly and entirely. Two thumbs up to West3D for bringing this product in.

Best bed for the prize

The fact that goes almost around the whole bed, helps a lot with the heating time. You don't need to wait forever for even heat distribution. I'm running it at 65% to avoid the bed to become a taco just in case.

Works great; thoughtful design

Bought the 116x116 for my Pandora's Box. It works perfectly and heats super quick (~1 degree/sec). Was especially happy to see that the wiring is offset from center, making it super easy to mount.
