Better sealing keeps the chamber heated up to 50 °C from the XL+ heatbed alone. The upcoming external heater can take that to 60 °C. The Enclosure for Prusa XL+ offers HEPA filtration, quieter prints, and full control from the printer menu.
Large ASA, ABS, PC, and Nylon parts shrink as they cool. If the air around them is cold and drafty, corners lift and may ruin the print. A sealed chamber slows that cooling so the part can finish the way you sliced it.
The enclosure for Prusa XL+ is an add-on designed specifically for the Prusa XL+ 3D printer. It is not compatible with the Original Prusa XL.
Everything useful from the XL Enclosure, with sealing improved for higher chamber temperatures and full readiness for XL+.
The Enclosure for Prusa XL+ improves sealing to maximize heating efficiency. In practice, the chamber temperature heats up to about 50 °C with just the heatbed. On large parts, that warm air is what keeps the corners down, especially with ASA, ABS, PC, Nylon, and PCCF.
The Advanced Filtration System draws air from inside and pushes it through a HEPA filter (99.9% efficiency). That cuts odors and ultra-fine particles when you print ABS, ASA, PA, and similar materials. Filtration is controlled from the printer menu, including post-print run time.
The Enclosure connects to the XL+ mainboard. From the touchscreen, you set filtration performance, check HEPA filter life, control the LED strips, and read the chamber temperature. An extra LED strip syncs with the printer for print-area light and status indication.
Some materials prefer cooler air. The magnetic bellows cover folds open for better airflow when you print PLA or PETG, without swinging doors that eat up floor space. You keep access to the whole bed, then seal up again when the next job needs heat.
Metal frame, Plexiglas panels, mounting points for cameras, electronics, and tidy cable routing. The enclosure also lowers printer noise and covers moving parts. Shipped as a kit with everything included - no printing required.
Warping on technical filaments is mostly thermal shock: hot plastic meeting cold room air. A stable, warmer chamber reduces that gradient. You get fewer failed large prints, less residual stress in finished parts, and much easier printing of the materials that refuse to behave on an unenclosed printer.
On open printers, room air cools each layer too fast. On XL-scale parts, that shows up as lifted corners and weak layer bonds.
A temperature around 50 °C is already in the useful range for ASA and ABS, and it helps a lot with Polyamide and many PC jobs. The part cools slowly, reducing the internal stress while the print is still running.
Around 60 °C (with the upcoming external heater add-on), you move into the temperature range recommended for printing polycarbonate and larger Nylon parts, where interlayer bonding and dimensional stability improve further.
Shipped as a kit. A 3D printer is not included. Tools for assembly can be added to the order.
Installed footprint matches the XL Enclosure platform. The Enclosure for Prusa XL+ adds improved sealing for higher chamber temperatures.
