Yiqiu3D PLA 1.75mm

Black is the hardest colour to sell on its own, because a dull or inconsistent black reads as cheap on a shelf. This is a deep, evenly pigmented black - pigment inside the PLA strand, not a top coating - so flat faces, edges and curved surfaces stay the same tone. On a black part every surface mark shows, which is why the strand is wound in one continuous length on the spool: fewer splices and fewer stands, so the outer surface of a printed part needs no sanding or touching up.

The distinctive feature is the hollow-core spool form: the filament is wound on a hollow cored reel, keeping the familiar round-spool handling that drops into a standard holder or dry box while using less plastic in the reel itself. It changes the packaging, not the filament - 1 kg net filament per spool is unaffected and the nozzle window stays 190-220 °C on a 1.75mm path. A lighter unit to freight and store, and less spool plastic entering your waste stream.

Adding a general-purpose black should not mean rebuilding a print profile. Nozzle window 190-220 °C with a 1.75mm filament path and a standard 0.4mm nozzle suits Bambu Lab, Creality and Prusa style desktop FDM printers, and no heated chamber is needed. No heated-bed temperature is published for this series, so keep the PLA bed setting the machine already runs. Dry the spool if it has been open in a humid workshop, then print jigs and display parts on the same profile you use for standard PLA.
