Everything You Need to Know About the Prusa XL 3D Printer Enclosure

As 3D printing continues to push boundaries, reliable hardware and accessories become crucial for consistent, high-quality results. That’s where the Original Prusa XL Enclosure comes in — a purpose-built, modular add-on for the Prusa XL 3D printer that ensures a stable printing environment, enhanced safety, and optimized performance with advanced materials.

In this blog, we’ll explore everything you need to know about the Prusa XL 3D Printer Enclosure: its features, benefits, smart integration, what's included, and more.

🔶 What is the Prusa XL Enclosure?

The Original Prusa XL Enclosure is an optional accessory specifically designed for the Prusa XL. It provides a controlled, enclosed environment that helps to stabilize internal temperature, reduce dust, minimize warping, and ensure optimal conditions when printing with high-performance materials like PCCF, Nylon, ASA, and PP.

🧠 Seamless Integration with the XL Printer

Unlike generic enclosures, the XL Enclosure is deeply integrated into the Prusa XL’s hardware and software ecosystem.

• Connects directly to the printer’s mainboard.

• Adds a new “Enclosure” menu on the touchscreen.

• Allows you to:

  • Set filtration performance levels.

  • Schedule post-print filtration (ideal for ASA or PCCF).

  • Control the LED lighting inside the enclosure.

  • Monitor the lifespan of the HEPA filter.

This seamless integration means everything works out-of-the-box — no need for third-party hacks or workarounds.

🧪 Built for Advanced Materials

The enclosure makes printing with engineering-grade materials significantly easier:

• HEPA filter with 99.9% efficiency removes ultra-fine particles (UFPS) and unpleasant odors.

• Smart airflow system draws air from below and expels it through the HEPA filter.

• Optional filtration mode for materials like PLA or PETG to preserve filter lifespan.

• Temperature visibility via a built-in thermometer and display readout.

• The integrated LED strip provides bright, synced lighting and status indication.

Whether you're printing durable nylon parts or carbon-filled composites, the enclosure ensures consistent performance and better print quality.
