Selective laser sintering porous conductive ceramic 3D printing consumable and preparation method
The invention discloses a selective laser sintering porous conductive ceramic 3D printing consumable and a preparation method, and relates to the technical field of porous conductive ceramics. The selective laser sintering porous conductive ceramic 3D printing consumable is prepared from the following components in percentage by mass: 30 to 60 weight percent of modified silicon carbide powder, 10 to 40 weight percent of conductive phase powder, 10 to 30 weight percent of macromolecular binder and 0.1 to 5 weight percent of lipid, and the selective laser sintering porous conductive ceramic 3D printing consumable is obtained through a direct mixing and ball milling method or a xylene solution mixing and water washing method. A porous conductive ceramic green body is printed by using a laser 3D printer, and a ceramic sintered part is obtained after thermal degreasing and sintering. The selective laser sintering porous conductive ceramic 3D printing consumable does not need to use a pore forming agent, is simple in preparation process and low in cost, has mass production conditions, and can solve the technical problems of large hot melting and oil conduction and storage of a porous conductive ceramic atomization core on the premise that a porous conductive ceramic body does not need to be made into a thin sheet.
