Yet Another Heated Bed Discussion

Hi All,

I am looking to build another printer in the style of a coreXY (HBot maybe) and I thought I would start of looking at heated beds. I know there's a lot more to consider, but I thought I'd start here.

My thoughts on what would like from a heated bed are:

• Removable print surface
• Reasonable heat-up time
• Bed size around 250x250

The Mk52 fullfills these requirements, but I want to know what other options I should consider

I have thought about a silicon heater attached to the bottom of an aluminium (presicion) plate. Or just use Mk3 heated bed with a glass top again.

If you have any suggestions or comments on what you have found that works for you, I'd like to hear about them.

Cheers.

Silicon heater under a 5mm aluminum plate works fine for me for 8 years now. On top i usually clamp a PEI plate for ABS printing. If i were to modify that printer again i might replace the clamping with a magnetic setups, but otherwise it is perfect for me.

Thanks for your reply Srek.

Couple of questions on your setup, what type of silicon heater did you use? (AC/DC) and how did you affix the silicon heater to the aluminium plate?

230VAC.The adhesive came with the heater, i would expect it to be 3M 9473 or similar.
