Eryone vs Prusament Galaxy Black PLA
The very first thing we noticed is that the Eryone filament is pigmented a dark grey. The Prusament has better contrast and less stringing.
Eryone Shipping, Packaging & Labeling
The shipping was free and took about a week to arrive. Considering that it was over the holidays, a week is pretty acceptable.
It looks like Eryone did have a 0.05 mm tolerance on this PLA according to their online pictures, but the current spools are 0.03mm. Their recommended print temperature range is the typical 190-220°C.
Eryone Filament Tolerance
The filament's diameter falls within tolerance - several measurements along the spool fell between 1.75-1.78 mm.
Print Temperatures for Eryone vs Prusament
The temperature towers present another good comparison for the color difference. It is difficult to tell that the color is a dark grey unless it is directly compared to a black print.
The ideal temperature for the Eryone Galaxy Black PLA on our Prusa MK3S at ≈20°C ambient is ~210°C, whereas on the Prusament we would run ~215°C. We like running our filament as hot as possible.
So far the Eryone filament is working fine, and there is very little difference between it and Prusament. The roll price was $27 with free shipping, which is about $10 cheaper than Prusament PLA. Hatchbox PLA is usually $20-25 so this is a good alternative if they are out of stock.
