Yiqiu3D PLA+ Basic 1.75mm

Copper is the colour name of a pigmented PLA: printed parts are plastic, not metal, and contain no metal. Nine colourways share the same high-gloss surface, with dark gold, crimson, Klein Blue, cyan and silver grey sitting beside the copper lead, so a collection can be colour-matched inside one supply line. High-gloss surfaces scatter light along curved geometry, which is what gives a display piece its depth.

Batch consistency is the whole point for a decor range: 1.75 mm round strand on a round spool, approx. 335 m per 1 kg net filament per spool, spool measuring 20 x 20 x 6 cm, wound in one continuous pattern so the feed stays even and the sheen stays uniform from part to part. Pigment is compounded before extrusion, so a repeat order arrives in the same copper as the reference spool you approved.

A glossy print shows every extrusion fault, so the strand has to run clean. Nozzle window 200-230 C, 1.75 mm diameter held on profile, no heated-bed setting required, and it runs on standard 1.75 mm FDM machines with a 0.4 mm nozzle. Keep the spool sealed until use: moisture produces bubbles and dull patches on a high-gloss surface, which is exactly the defect this finish is bought to avoid.
