3D Printer Enclosure Bundle Prusa Original MK4S (PSA-26401) for MK4S Printer

The Prusa 3D Printer Enclosure Bundle for the Original MK4S is a tailored enclosure solution designed to fit the MK4S desktop 3D printer. It creates a controlled printing environment to reduce drafts, stabilize ambient temperature around the build area, and help contain fumes and particulates produced during printing. The bundle supports consistent printing results with temperature-sensitive filaments and aims to make workshop or desktop operation cleaner and more predictable.

Advantages

The enclosure maintains a more stable internal temperature, which improves adhesion and reduces warping on larger or temperature-sensitive prints. By limiting airflow and containing emissions, it supports safer and cleaner operation in indoor spaces. The design is matched to the printer’s form factor to allow full access to controls and visibility while installed, preserving ease of use and monitoring during long prints.

Suitable for

• Printing with ABS, ASA, PETG and other materials that benefit from temperature consistency
• Desktop and workshop environments where fumes and drafts are a concern
• Long-duration or large-part prints requiring reduced warping and improved layer adhesion
• Users seeking a tidier printing area and easier containment of particulates

Key specifications

• Purpose-built fit for the Prusa Original MK4S printer form factor
• Rigid panels that create an enclosed build chamber to reduce airflow
• Transparent viewing panels or windows for print monitoring
• Access points allowing operation of printer controls and filament changes without full removal of the enclosure
• Materials selected for workshop and desktop use to balance durability and weight

How to use

Install the enclosure around the MK4S following manufacturer instructions to ensure correct alignment and secure attachment. Place the printer on a stable, level surface before fitting the enclosure and verify that access panels align with control interfaces and filament paths. During printing, monitor internal temperature and ventilation as appropriate for the filament in use, and use the enclosure’s access features for filament changes or printer maintenance when needed.

Usage recommendations

Use the enclosure with materials that benefit from reduced drafts and more consistent chamber temperatures. Ensure adequate ventilation in the room and periodically inspect seals, panels, and access points for wear. When printing filaments with stronger fumes, consider combining the enclosure with appropriate room ventilation or filtration solutions to manage air quality.
