Description

Technical Field

[0001] The utility model relates to the field of 3D printing, in particular to a sealed drying box for 3D printing consumables. Background Art

[0002] A sealed drying box for 3D printing filaments is a device used to store and protect printing filaments to ensure that they remain dry before printing. Moisture can have a negative impact on 3D printing filaments, resulting in a decrease in print quality. Therefore, a sealed drying box can effectively prevent moisture from entering and extend the service life of the filaments. The box must be completely sealed to prevent moisture from entering and use transparent or translucent materials so that users can check the status of the filaments inside the box.

[0003] There are various technical solutions for 3D printing filament drying boxes on the market. They usually adopt electronic control systems with heating temperature control and humidity monitoring functions to achieve precise control of temperature and humidity. They can actively heat and dry and have humidity monitoring functions, but the airtightness design is not good. In addition, there are simple sealed drying boxes and industrial-grade drying ovens. The existing technologies either have only sealing functions or heating functions. There is no 3D printing filament sealed drying box that integrates the two functions of sealing and heating. The filaments cannot be stored for a long time without moisture, or the heating function needs to be turned on for a long time to keep it dry, but the energy consumption is high, and long-term high temperature will affect the quality of 3D printing filaments. For this reason, we propose a 3D printing filament sealed drying box. Utility Model Content
