Methods of additive manufacturing for ceramics using microwaves

An additive manufacturing method for forming a ceramic part, the method comprising:

• dispensing a plurality of successive layers of feed material, the feed material comprising a curable component;
• emitting a radiation toward at least one layer of the feed material as or after each layer of the successive layers is dispensed, the radiation being configured to cure the curable component of the feed material;
• and
• applying microwaves directed toward the successive layers, the microwaves being configured to vaporize the curable component of the feed material and to cause crystallization of the feed material to form the ceramic part.

An additive manufacturing method, the method comprising:

• dispensing a first layer of a first feed material, the first feed material comprising a curable component and a ceramic component;
• emitting a radiation toward the first layer of the first feed material to cure the curable component of the first feed material in the first layer;
• dispensing a second layer of a second feed material on the first layer, the second feed material comprising the curable component and the ceramic component;
• emitting the radiation toward the second layer of the second feed material to cure the curable component of the second feed material in the second layer;
• dispensing a third layer of the first feed material on the second layer of the second feed material;
• emitting the radiation toward the third layer of the first feed material to cure the curable component of the first feed material in the third layer;
• and
• applying microwaves to a plurality of layers comprising at least the first, second, and third layers to crystallize and sinter the ceramic component of the feed material of the plurality of layers.
