Title:
METHODS OF ADDITIVE MANUFACTURING FOR CERAMICS USING MICROWAVES
Document Type and Number:
WIPO Patent Application WO/2017/172480
Kind Code:
A3
Abstract:
An additive manufacturing apparatus for forming a ceramic part includes a platform to support the ceramic part to be formed and a dispenser to dispense successive layers of feed material over the platform. The feed material includes a curable component. The apparatus further includes a radiation source to emit a radiation toward a top surface of the platform and a microwave source to apply microwaves directed toward the successive layers on the platform. The radiation is configured to cure the curable component of the feed material as or after each layer is dispensed. The microwaves are configured to vaporize the curable component of the feed material and to cause crystallization of the feed material to form the ceramic part.
