oliveindustry Great question! I was actually going open a thread like this, I think ABS deserves another look.
In general ABS / ASA have the same mechanical properties and I'll treat them together. The ABS I've tested has been significantly weaker then PLA+, as much as 25%. With a heated chamber layer adhesion may be good, but short of that and you will have problems with layers splitting.
With the new super lower designs I think they are strong enough that ABS would work, but you would be excepting a marginal level of strength for relatively small savings over using PET-CF.
