World’s first smart 3D printer enclosure.
The Clura Enclosure is the open-source home your printer deserves. Compatible with Prusa (MK4/MK3/Mini), Bambu A1/A1 mini, and Ender 3 style printers, it integrates air filtration, safety sensors, filament weight sensing and more; All controlled via a 4.3” touchscreen.

Breathe Clean, Print Safe
Engineered for total air management, Clura features high-performance 12032 fans and HEPA carbon filtration. Dual MG996 servos dynamically control air flow between closed-loop recirculation and open-loop venting. The system filters the entire enclosure volume in just 60 seconds, and on Pro series models, it automatically switches to open-loop if internal temperatures exceed safety thresholds.
Filament tracking, No more surprises
Never run out mid-print again. Our integrated spool holders use an HX711-based load cell system to track filament weight in real-time, automatically subtracting the spool's tare weight. With 16 pre-configured filament profiles and high-precision tracking (±2g) when calibrated, you can easily modify or add custom materials to suit your workflow.
Monitor the air & Detect smoke
Monitor your printing environment with a dedicated sensor suite. Clura uses the PMS5003 for PM0.3/PM2.5 tracking and the BME680 for temperature, humidity, and pressure. For safety, it combines an MQ2 sensor with MEMS and optical smoke sensors to detect methane and fire particles instantly.
Control everything at the touch of a finger
Control every aspect of the enclosure from the 4.3” display. Adjust filtration speed, view the current filament weight, view the current environmental values like temperature, humidity and so much more.
