Hi

I am very new to 3d printing (about a week now), but this one is a little odd and I wonder if someone can point me in the right direction...

I have a Wanhao i3 Plus. I am trying to print a few parts to firm up my z axis on the printer. I am using Cura, setup for the i3 with all the default settings other that a shell of 1.2mm and layer height of 0.2mm.
I am printing with 1.75mm black PLA from 3D4Use.

In the photo, I am holding the part in the same orientation it was printed. The warping seems to be happening quite late into the print, well after the layers that are warping.
I lef tthe print running over night , with all 3 parts that I printed coming out with the same issue, this one being the worst.

I am printing with the bed cold and no raft.

Could this be a filament issue?

Many thanks

Mr S
