[Turning off Bed/Built plate Temperature after x layers?.]

Just a heads up from someone who has experimented with this - don't leave your print unmonitored. 

 

This  issue probably only applies to glass beds, but on both my ender 3 and CR10, if the the print is a long duration print, the bed cools to the extent the print WILL detach, and potentially cause a catastrophic fail and risk destroying some/all of your printer.  

 

Yes you are correct this does indeed happen, when turning off the bed like this you need some additional process of keeping the print on the bed, textured surface or adhesives. We are a research group looking at the energy demand for 3d printing, all methods and its carbon footprint.

It's not only this. In addition you will change also the distance between nozzle and bed (misalignment of the build plate could come also in place). In the end you will see this in the print optical and dimensional.

 

There is thermal expansion in the plate however the delta is very small and  is having little effect when compared to the thickness of extrusion. We measure this also during the testing.

 

Thanks for your help, its great to have your experience as a resource.

@DivingDuck, thanks for this, really helped me out in some experimental printing we are doing.
