One thing about FDM printing is that as it lays down the filament layer (mine is set up to do the outer line (shell) first
and then fill it in with a crisscross pattern) it may take it a while to get around to where it started to begin the next layer.
This will allow the PLA print to cool a bit and as the next layer begins, it can only sink in (adhere) to the previous layer so much and not be
completely blended smooth as it advances up. This will cause a bit of a noticeable layer change along the outer surface
of the printed item. The extruder pushes out the filament while the back edge of the heated nozzle "trowels down" the
filament it just pushed out.
It will "squish down" the filament bead a bit to make it flatter, but the outer edge will still be a bit rounded.
It is the nature of FDM style printing.
Not sure how this company has solved the "physics" of deposit style printing with just a formula change,
only the reflectiveness.
As with all 3D printers the settings and printer set up designates the quality of the final print.
I wonder if they tested this new filament formula with a well tuned, highly accurate machine?
I have printed the exact same object, using the same PLA, with the same .stl and CURA settings on my E3 and CR-10S and there was a noticeable difference between the two. They where both good, but different, due to the machine differences.
The close up pictures on the web sight shows the layer difference as FDM does. Horizontal, Vertical, Diagonal.
