So far, I have handled several spools of different colors. Black, silver, gold, red, aquamarine, pink panther, levanter, I might be forgetting some...
With a cost of around 14 for occasional use with some more unique colors than the usual ones, and when print quality is not the main concern, it's okay.
Otherwise, with these specific filaments, you get what you pay for.
The diameter of the filament does not have any particular accuracy; at random points where I measured it, I saw from 1.71 to 1.79mm regardless of the spool and color. Also, even though I dried it for 8-12 hours and it had no trace of moisture, in some spots it breaks easily and in others, it bends without breaking... Something might not be going well with the mixing of materials at the factory...?
Due to the above, on external walls and flat surfaces, the layer lines will always appear pronounced and irregular due to over and under extrusion; it cannot be fixed.
Otherwise, it prints very well on overhangs, and the winding on the spool is okay acceptable, although it looks somewhat irregular, I did not encounter any particular problem with the PLA+.
If you use it in a filament holder with rollers that press externally on the spool, you need to clean the few plastic burrs left from molding with a scalpel/deburring tool so that it doesn’t hinder the spool during rotation and affect print quality.
(On the PETG from the same company that I tried once, the winding was unacceptable, very tangled; maybe I just got a bad one, I don’t know... Anyway, I definitely won’t buy PETG again; I prefer my peace of mind even if I have to pay a bit more...)
I mainly use it to print toys and figures for the kids, so the above does not affect me except for the clogging which is breaking...
It has some difficulty with supports that are relatively hard to remove; I might need to reduce the flow ratio a bit in the support settings.
Once, the nozzle clogged from the filament itself without finding any foreign object; I haven’t experienced this with higher quality filaments. I lowered the printing temperature by 5°C as a test, and it hasn’t happened again so far.
