3D printer filament Elegoo Rapid PLA+ 1.75 mm Gray, 1 kg spool

Rapid PLA+ ELEGOO Filament in gray is a 1 kg spool of plant‑based, biodegradable polylactide modified for increased durability. Designed for fast, technical 3D printing, the muted gray color hides minor surface imperfections and highlights model geometry. The material is suited for functional parts, prototypes and structural elements where repeatability and dimensional accuracy matter.

Advantages

Rapid PLA+ melts and flows quickly, enabling high‑speed printing when the printer is properly tuned. Compared with standard PLA, this PLA+ offers improved flexibility and resistance to cracking, producing less brittle parts. Good thermal conductivity helps layer adhesion. The filament is wound by machine and inspected by hand to minimize tangles; it comes vacuum‑packed on a recycled cardboard spool with a moisture absorber, ready for immediate use.

How to use

Load the 1.75 mm filament into a printer adjusted for PLA family materials. Preheat the nozzle to 200–230°C and set the build plate to 35–65°C according to your printer and surface type (textured PEI or another compatible plate recommended). For best results dry the filament at about 55 ± 5°C before printing if it has absorbed moisture. Tune retraction and cooling to suit high‑speed printing and verify that the printer can handle elevated extrusion speeds up to the recommended limit. After opening, keep the spool with the moisture absorber when not in use.

Recommendations

Use textured PEI or another compatible build surface to improve adhesion, store the vacuum‑packed spool with the moisture absorber in a dry place, and perform test prints when changing speed or temperature settings to ensure dimensional accuracy and surface quality.
