Prusament PLA Gentleman's Grey 1kg (NFC)

Product description

Prusament PLA Gentleman's Grey 1kg (NFC) is a premium PLA filament manufactured directly by Prusa Research. The elegant gray‑graphite shade Gentleman's Grey gives your prints a professional, “technical” look, whether you are printing functional prototypes, design models, or miniatures.

Prusament PLA is known for its exceptional dimensional accuracy of ±0.02 mm and very consistent color throughout the spool. Each batch is carefully inspected and you can check the parameters of a specific spool via the QR code on the label.

Thanks to the new generation of spools introduced in October 2025, this product is equipped with an NFC label compliant with the open OpenPrintTag standard. Your printer (or the Prusa mobile app) can immediately read key material information from the spool – completely offline, without any dependency on the cloud.

Key features

• Premium Prusament PLA filament – in‑house production by Prusa Research with full quality control.
• Diameter accuracy ±0.02 mm – reliable extruder operation, minimal clogging, and consistent results.
• Gentleman's Grey shade – universal, elegant gray‑graphite color suitable for both technical and decorative models.
• Integrated NFC (OpenPrintTag) – the spool contains a fully rewritable NFC tag with stored filament data.
• Easy printing even for beginners – PLA is one of the least demanding materials in terms of setup and environment.
• Low warping – suitable for large models and using the full print bed area.
• High stiffness, detailed surface – ideal for prototypes, concept models, miniatures, and presentation models.
• Made in the EU – consistent quality, regular parameter control of every spool.

Use cases and suitable applications

This filament is particularly suitable for:

• functional and design prototypes (mechanical parts, covers, brackets, jigs in non‑demanding conditions),
• concept models and mock‑ups (architectural models, product design),
• miniatures, models, and figurines with high surface detail,
• teaching aids and demonstration models for schools and 3D printing clubs,
• interior decorations and accessories that are not exposed to high temperatures or UV radiation.

It is not ideal for parts:

• exposed to temperatures above approx. 55–60 °C (e.g. inside a car in the sun),
• placed outdoors for long periods (PLA has lower UV and temperature resistance).

Print settings (approximate)

Recommended printing parameters according to the manufacturer:

PLA generally allows higher print speeds and does not require an enclosed chamber. For best results, we recommend enabling full part cooling and printing in a draft‑free environment.

NFC and OpenPrintTag

The new generation of Prusament spools is equipped with a rewritable NFC tag according to the OpenPrintTag standard:

• contains key information about the material (type, color, recommended temperatures, other metadata),
• data is stored directly in the tag – works fully offline,
• compatible across brands and ecosystems,
• can be read e.g. by the Prusa mobile app and supported 3D printers,
• open standard – no vendor lock‑in and no licensing fees.

This way, you always know which material is loaded on the printer, and you can easily automate profile selection in supported software and devices.

Tips for printing and post‑processing

• First layer: Keep the print sheet clean (isopropyl alcohol on PEI) and pay attention to the correct first‑layer height.
• Cooling: PLA loves strong cooling – using a high‑power part‑cooling fan improves details and bridging.
• Sanding: Use wet sanding for PLA – without water, the plastic quickly overheats from friction, softens, and deforms.
• Gluing: PLA parts can be glued using cyanoacrylate (CA) super glue. For very strong joints, special plastic adhesives can also be used.
