Bed Warmer

thingiverse

I'm so fed up with the Anycubic I3 Mega Ultrabase taking a whole half hour to warm up, so I took matters into my own hands and installed the mosfet. That was a game-changer, but it still took over 20 minutes for my PETG to heat up from room temperature to 95 c. I've had enough of that. I decided to take action and created this solution to cover my 210 x 210 mm bed. It covers about 95% of the bed's surface area. You can use any material you like, as long as it's not flammable. I'm using a cloth embedded aluminum heat barrier cloth that I happen to have on hand. Aluminum is an excellent material for a radiant heat barrier. When this is placed on my bed and the bed reaches 95 c, I can barely feel the heat with my hand just one inch away. Remove the barrier and you'll be amazed at how much heat you feel. It reflects the heat right back into the bed. All I did was cut the fabric larger than the frame, fold it over, and secure it with tape. I've doubled up the fabric for added protection. Simply place it on the bed when you start printing, but be careful - it heats up extremely fast. I'm thrilled to report that I was able to heat my bed from room temperature to 95 c in under ten minutes (check out the picture). UPDATE: I made some changes to the handle to make it easier to grasp. I highly recommend using the V2.stl file for this design.
