Hi, i've just changed filament from translucent blue 3mm PLA from reprapcentral.com to a roll of white PLA from mendel-parts (ultimachine), and have had to consequently change temperature (237 to 255), filament diameter (filament is 2.75, lowered to 2.65) and extrusion multiplier settings in slic3r (from 1.0 to 1.25) in order for the perimeters to melt together, (otherwise it is easy to get a fingernail in between each of the perimeters and it peels away. Layer adhesion seems fine.

Just wondering what sort of experiences you guys have had with this material.
