I'm kind of a noob at PLA printing. I started with a DaVinci, and only ran ABS through it. It is an enclosed printer, which is what ABS apparently likes. I finally got tired of $70 cartridges and ditched it in favor of an Ender 3, and started using PLA. I've done a couple experimental prints with ABS, but have adhesion problems with the magnetic flexible mat you get as a print bed. I do have a glass print bed, and one of these days I'll re-calibrate the Z axis and try it out.
I have noted, however, that my roll of PLA filament, which is exposed to the sun when installed in the printer, seems to get brittle very quickly while the ABS does not. It might be that I'm using cheap Amazon Basics filament, and need to go back to a pricier, name brand. The things I have sitting around the house here that were printed in PLA seem to be holding up just fine, and a couple of them sit right in the sunlight for extended periods of the day. I'm doing some minor structure for the 688 in PLA, and so far they've all come out excellent, and seem to have no trouble being drilled and holding fasteners. I would like to do more experimentation with ABS, however...
