There are all sorts of stories of what to put on your printer bed to make your part not come loose when it is printing but can be removed after it is done without requiring a hammer and chisel.
Is there anything out there that shows an analytical comparison?
My biggest interest is PLA on a heated glass base.
I use a product called 3DLAC but I suppose it's regular hairspray. Makes my PLA stick to the heated bed like a charm. After cooling down the print can be removed from the bed with ease.
Only today, after a few thousand prints the glass bed of my printer broke. But I suppose this is because we didn't have enough patience to let the bed cool down to room temperature before removing the printed piece.
