Thanks a lot for the printing tips! I had some issues with stringing and melting layer issues with the 2kg pearl white filament I ordered.
I have to say your speed of delivery is amazing! I ordered my filament (a boatload I might add) Wednesday, Friday morning it was all here .

Hi, if the PLA/PHA breaks much faster then I would guess the bonding between the layers isn't optimal. Perhaps because of slight extrusion problems? or maybe just printing to fast.
For the stringing you can try lowering temperature (if the print speed allows for this), increase travel speed 250 mm/s, increase retraction speed 45 mm/s. You can also experiment with retraction distance.
Looking at your printed part the last bit is probably printed to fast, it looks like the material might have needed a bit more cooling time. So you could also change the minimal layer time to about 8-10 seconds. This should mean the print will be slowed down towards the end, which also means you can drop the temperature by quite a bit.
As an example, the bracelet was printed at 20 mm/s at 195 C. We used to print these at the normal temp of 215, but because of lowering the print speed the temperature can be reduced by a lot.
Hope this is helpful.
