I have Anycubic I3 Mega S and there is a PLA spool in the box. I ran about 8 spools of stuff from about 5 different brands. I've had some of the best results with the original spool, so I decided to buy a different spool. I am again very satisfied with the quality. The first thing I did was a makeshift tower and some pews for confirmation. Benci is printed at 190c on the left and 205c on the right. None of these prints used additional plate adhesion and the heated plate was set at 50°C. This could also be proof that the I3 Mega bed has superior grip. The spool is well wound and I don't expect it to get stuck. I've taken a few spot measurements and found it to be a 1.72 diameter on every check so far. Undersized filament diameter seems to be the norm across all brands as every spool I tested ranged from 1.70 to 1.72. I printed the benches at 0.2mm layer height with 10% infill and double walls and they are impressively strong. The temporary tower was printed without infill. I printed everything at 60mm/s and would probably slow down a bit if I wanted to improve overall quality. Layer adhesion with this PLA is extremely impressive, I haven't noticed any loose layers even on the very thin corners of their temp tower. If you're interested, here are the exact settings I think are best: Temperature • 190°C - 200 Bed • 50°C Print Speed • Varies with detail, but I was able to get decent detail even at 60mm/s. Retraction • 4.5mm
