Speed

SLOWER than plain PLA — 25–45 mm/s. The sheen comes from additives that need dwell time at temperature to flow properly, so rushing it prints dull and rough, which people then misdiagnose as a bad spool.

Bed surface

Smooth PEI gives the glossiest bottom surface, which suits this material.

What bites people

Runs HOTTER than normal PLA — the sheen comes from additives that need more heat to flow properly. A standard PLA profile prints it dull and rough.
Noticeably WEAKER between layers. The same additives that create the shine interfere with layer bonding, so this is a decorative material, not a functional one.
Less fan gives more shine but weaker parts. That trade is the entire tuning decision on this filament.
Strings more than plain PLA. Expect to spend real time on retraction, and dry the spool first.

Safety

Nozzle runs above 210 °C.
