Product Description

Prusament PLA Gravity Grey 1kg (NFC) is a premium PLA filament from Prusa Research in a universal light gray color Gravity Grey. It is produced internally on Prusa's own lines, where diameter tolerance, color consistency, and mechanical properties are monitored at all times. The result is a filament with an extremely stable diameter of ±0.02 mm, guaranteeing reliable extruder operation and clean, precise prints.

The new generation of spools is equipped with an NFC tag according to the OpenPrintTag standard, which allows for easy reading of filament information (material, color, remaining amount, etc.) by compatible printers and accessories. This simplifies material management and minimizes setup errors.

Gravity Grey is a neutral light gray shade, ideal for functional parts, prototypes, models, technical components, and design objects, where detail stands out and small imperfections are not visible on the print. PLA is very easy to print, does not require an enclosed space, and thanks to minimal warping, it is suitable even for larger models.

Printing Tips

• Before printing, clean the print bed (IPA, according to the printer manufacturer's recommendations) to ensure good first layer adhesion.
• Use 100 % cooling, especially for smaller detailed models.
• For larger parts, we recommend a bed temperature of 50–60 °C and a reasonable layer height (0.15–0.25 mm) for a balance between quality and speed.
• Do not expose finished prints to higher temperatures (above approx. 55–60 °C) for long periods; the material is PLA and may soften.
