Simple HotBed Insulator

[seaton]

I've started playing around printing ABS with my Felix and want the hotbed to get up to the higher temperatures, so I though I'd try some simple insulation on the bottom of the hotbed before trying something else.

I ended up cutting up a cardboard box that an appliance came in and taped it on the bottom with some Kapton tape, now I'm achieving 100Deg C on the hotplate after about 20 minutes of warmup, where before I'd be lucky to get 80DegC, I haven't tried hotter yet but I'm sure it will go higher given time. Just as aSide the room I have my printer in is pretty open and cold so I'm happy that it can achieve this temperature.

watch out , high bed temperature are likely to make your print head sag a little, it happened to me when i was playing with ABS and pushing the bed towards 95C....happened to others too.
Good idea to print a set of spare parts first.

First thing I did

Also the first thing I'm printing with ABS is a set of spares

Either way I'm covered

Success !

You can reach the desired start-temperature a lot faster if you put a towel on top of the hotbed.

Although 100 degrees is far from autoignition temperature, I personally wont feel comfortable putting paper on a heater (if unattended). But the idea is great. Maybe search for a lightweight heat-resistant isolation plate?

edit:
According this forensic paper: http://www.tcforensic.com.au/docs/article10.html
Paper show signs of burn marks at 150°C and ignites between 218°C and 246°C
