If a fan blowing at the newly extruded filament causes layer separation when printing with ABS, could that be used to get rafting and support that doesn’t bind so hard?
That is a good idea but I am not sure if it could be applied selectively enough to affect just the support areas. It would be good for rafting a the flat bottom of a part.
I’ve considered the same thing but it’s unnecessary in fact. The Alfina/up! Printers have been doing break away support for years and it appears to be all about speed, direction and flow rate. None of the open source slicers seem to have cracked it yet though.
