Rapid PLA+ (polylactide plus - plant-derived, biodegradable material, enriched with additives to increase durability) in the ELEGOO gray version is a fast filament designed for technical printing. The muted color hides minor flaws and allows you to focus on the model's shape. The material works well for utility projects, prototypes and structural elements where accuracy and repeatability are important. The reel contains 1 kg of plastic.
