Title:
MULTI-FIELD COMPOSITE-BASED ADDITIVE MANUFACTURING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/121002
Kind Code:
A1
Abstract:
The present invention belongs to the technical field related to additive manufacturing, and discloses a multi-field composite-based additive manufacturing device and method. The device comprises a powder delivery adjustment module, a sound field control module, a microwave field/thermal field control module and a microprocessor. The powder delivery adjustment module, the sound field control module and the microwave field/thermal field control module are respectively connected to the microprocessor; the powder delivery adjustment module comprises a raw material dispersion chamber, and the raw material dispersion chamber is provided within a forming cavity formed by a housing; the sound field control module is also provided within the forming cavity and is located below the raw material dispersion chamber; the microwave field/thermal field control module comprises a plurality of microwave generators provided in the forming cavity, the plurality of microwave generators are respectively located at two sides of a forming area, and the microwave generator and the sound field control module are respectively located at two opposite sides of the raw material dispersion chamber; wherein the forming area is divided into a high-temperature area and a low-temperature area, and the temperature of the high-temperature area is higher than that of the low-temperature area. The present invention mitigates the trend of cracking, and the forming efficiency and precision can be adjusted.
