SoliForum - 3D Printing Community → Solidoodle Press → How to improve heated bed? 110°C takes more than an hour!
How long does it take you to heat up the bed to 110°C? Mine took more than an hour!
Are there any ways to improve this? Or is the only option to replace the whole heating bed to something better?
Other posters have reported 10-11 min to 110c. Please open a ticket with SD so they know I'm not the only one. (18 min to just 100c). Search for the post "Bed Time".
Aaaand... it's dead. After turning the printer off and on again it stopped heating the bed. Looking at the heating element I can see that it burned. Strange that it struggled with 110°C. Be cautious if you are heating to this temperature.
Thanks trayracing for pointing to Bed Time thread. I'll contact Solidoodle straight away.
I heat my bed to 110 all the time and even have a 3mm thick piece of tempered glass on top of the stock glass. Mine takes about 15 minutes max to reach 110. Depending on the ambient temp as well.
I used some ceramic wool 1/8" thick underneath the heating pad. It reduces heating times by about 20% in my experience, your mileage may vary....

Does it reduce the overall heat in the press much with the wool there? I wonder if this could enable the printer to run closed.

Why so hot? 90% of my prints in ABS are done in the 90-95C range with no problems.

I have Kapton tape on my bed. I had to put temperature up to 110C to get the first layer to stick reliably. And looks like it's recommended temperature on reprap.org wiki for ABS as well.
Solidoodle support was very helpful and I should get my tracking number tomorrow for the replacement heating element.
In the meantime I got some PLA to try printing while I wait for my heating element replacement.
My heating element just went out as well.
Was just doing a standard print of ABS at 95c but it appears it has burnt out.
I can see one of the 3 leads have been burnt out. My feeling is, this is caused by using a very low AWG for temp/amp resistance and also could be caused by the printer bed being heated while the bed is at its lowest position, there by causing too much heat to build up on the bed wires and then burning up.
The bed refuses to go higher than 50c in this condition and it seem to happen mid/print (where the temperature dropped from 95 to 50c, but of course by then the printing could finish without a problem.
Sad 
Will put in a request to Solidoodle support for me to get a replacement.
good news is you don't need the heated bed to print ABS if you have enough space and time to print at 1mm and add a huge brim to whatever you print. As long as you have some hairspray it works like a charm still..
well, at least I can still print until solidoodle sends me a new heating element.
I got tired of wasting all that time waiting for the thing to heat up and so I replaced the stock heating pad with a 120v pad. I used a solid state relay to run the thing off of my mains power, which is really nice not having the power supply involved. The only thing about doing it this way is that you have to update the firmware with the new PID settings but that's easy enough. So now I get up to 95C in about a minute. That saves me a considerable amount of time.
Put an hairdryer to run over bed. DO THIS ON YOUR OWN RISK !!!!

Don't even think about using a hair dryer. I broke one glass in my old printer by doing this. Hair dryer does only warm a part of the glass and the difference in temperature will break your glass.

This is why you should buy replacements. I broke original glass bed looooooooooooooong time ago, then I bought from a local store 5 glass beds. 50 cents each 
. STILL DO IT ON YOUR OWN RISK !!! (I mean the hair dryer thing).
BTW: The glass broke before I even think of using hair dryer.
