ABS? (or is it HDPE?) Die Swell part 2!

(Update : See note in ABS “Die Swell” from hell! for update on the confusion over what materials I was trying to print with)

Ok I persisted with testing this offending roll of (what I thought was) ABS, unfortunately whatever I tweak to try and resolve the quality issues with this plastic I just can’t seem to get consistent results, and eventually getting frustrated enough to invest in a new reel of “Black Premium ABS” it arrived the other day and to my surprise feels completely different to the reel of natural “what I thought was” ABS that I was given.

I am now thinking that this free reel of plastic is probably not ABS at all but could well be HDPE, it has been put back into storage for now until I can be bothered to have another go.
