I have problem printing a simply cube object using Ultimaker 2+.
Below show the comparison of two objects;
Green --> Successful printed
Blue --> Failed printed (defect); and the printed cube has less strength than normal. I can squeeze (and maybe destroy) it easily with two fingers.
Both print with the same Ultimaker PLA 2.85 material (just a different color), and the same CURA file.
What wrong with the printing in blue?
I used to face this problem once last year, but after I reprinted, the problem disappears.
This time, even though I tried to print multiple times, the problem still persist.
