I was wondering if anyone has tried to add a "blanket" their heated bed to speed coming up to temperature? For PLA, coming up to temperature is not a big deal, since the HBP comes up to lower temps really fast. But for ABS, waiting to come up to 100°+ C takes time (about 10 minutes). By adding a blanket (like fiberglass accoustic ceiling tile), it takes less time. You would have to not handle the "blanket" by hand, since you don't want any oils etc... on anything that touches the build platform. I am also trying a Kapton tape the fiberglass panel to boost the insulation R-Factor. I am also trying cellulose ceiling tiles, they are a bit heavier. Last year, I tried to burn one up in a wood stove that was red hot on the outside. The wood stove didn't even singe the cellulose panel. Whatever the heat treatment they added to it, it works extremely well. If you have done this, what material are you using? For waiting on cooldown periods of the bed, I blow a fan to speed it up a bit, although I have been playing with the idea of swapping glass plates like "pallets" used in high speed machining centers, and pre-heating the glass plates in a lab oven to reduce the wait time. https://reprap.org/forum/read.php?1,154502,154502#msg-154502 Sun, 19 Apr 2026 16:26:27 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,154502,154627#msg-154627 https://reprap.org/forum/read.php?1,154502,154627#msg-154627 jcabrer General Sat, 15 Sep 2012 17:56:31 -0400 https://reprap.org/forum/read.php?1,154502,154573#msg-154573 https://reprap.org/forum/read.php?1,154502,154573#msg-154573 xiando General Sat, 15 Sep 2012 11:49:32 -0400 https://reprap.org/forum/read.php?1,154502,154568#msg-154568 https://reprap.org/forum/read.php?1,154502,154568#msg-154568
For smaller prints, and with a decent Z calibration, you probably don't have to wait for 100°C. I've been slacking off by about 20° lately on some parts with about a 200mm² base. I could probably go cooler, since they are really stuck on there (I haven't been waiting for the bed to cool much either).]]> Dale Dunn General Sat, 15 Sep 2012 10:44:44 -0400 https://reprap.org/forum/read.php?1,154502,154503#msg-154503 https://reprap.org/forum/read.php?1,154502,154503#msg-154503 IanJohnson General Fri, 14 Sep 2012 22:48:54 -0400 https://reprap.org/forum/read.php?1,154502,154502#msg-154502 https://reprap.org/forum/read.php?1,154502,154502#msg-154502
