I have been thinking about how to make a drop in bed system, with swappable print surfaces. I believe I just figured it out but have to design it tonight when I get home. The idea is to have the heater fixed to a new platform, where the current built plate is. On top of that, the print bed will drop in and be removable when done. Goals are: Not lose any X and Y print area, and only a few mm of z travel.
My idea is to redesign the current bed corners and make them and the heater plate / build plate holder one piece. This will eliminate the “tab” used to hold the bed in place, which frees up the top for a drop in build plate. The heater will then be removed from the build plate and attached to the heater plate. I’d also like to permanently fix the “home” corner of the bed to help make leveling easier. I plan on reusing the glass / PEI print bed.
Hopefully I’ll get some renders up tonight.
