Abstract
Method, system, and apparatus for drying materials used in additive manufacturing and, more particularly, drying systems which are capable of rapidly drying polymers by alternating heating, and low-pressure cycles without affecting material properties.
Claims18
A vacuum drying apparatus for drying plastic filament, granular, powdery plastic resins or metallic material comprising:
- a sealed chamber.
- a sensing element for measuring a temperature at a position inside said sealed chamber;
- a heating element for heating said sealed chamber prior to drying;
- an airflow directing element for keeping a temperature and humidity homogeneous inside said sealed chamber;
- a vacuum generating element for generating vacuum within said sealed chamber at said position;
- and
- a chemical desiccant for drying air entering the sealed chamber prior to the vacuum generation.
4 more elements
A method for drying material used in additive manufacturing, said method comprising:
- heating air inside a sealed chamber configured to contain a material used in additive manufacturing;
- monitoring a temperature inside said sealed chamber and regulating the heating of air to ensure that said temperature does not exceed a predefined temperature;
- directing said heated air through the material;
- and
- generating a vacuum inside said sealed chamber so that said material is dried.
