BCN3D Smart Cabinet Debuts to Store 3D Printing Filaments at Optimum Humidity Levels

BCN3D, a Spanish 3D printing solutions manufacturer, has launched the new Smart Cabinet to complete the Epsilon ecosystem, which boosts the entire printing process with BCN3D workbench 3D printers Epsilon W27 and Epsilon W50.

The BCN3D Smart Cabinet relies on smart drying technology to ensure that filaments are consistently kept at optimal humidity levels, protecting against print failure and nozzle clogging.

The filament humidity control keeps materials in optimal condition, and an Uninterruptible Power Supply (UPS) protects the print job at all times, eliminating the risk of losing a print job due to power outages.

The BCN3D Smart Cabinet works on the absorption dryer method, alternating between drying cycles and regeneration cycles to maintain a constant dry environment around the stored spools and protect them from sudden external changes.

The Smart Cabinet controls relative humidity inside the air-tight container through a desiccant that absorbs moisture, in this case, alumina-based pellets, which are open to the dehumidifying environment.

By isolating the absorption material from the heating chamber and increasing its temperature, the absorbed humidity is released outside of the chamber and the material is regenerated. After the purge, the desiccant has been refreshed and is ready to collect more moisture. The air-tight container and cyclical internal ventilation through the fan, heat and valves, means there is no user interaction required.

This process effectively keeps the filament dry and in optimal condition for its use, and means that there is never a need to change the desiccant.
