Abstract: A permanent magnetic alloy powder includes rare earth elements, iron, boron, aluminum, copper and carbides. The rare earth elements include neodymium, and account for 24 to 30 parts by weight. Iron accounts for 65 to 72 parts by weight. Boron accounts for 0.8 to 1.2 parts by weight. Cobalt accounts for 2.8 to 3.2 parts by weight. Aluminum accounts for 0.2 to 0.6 parts by weight. Copper accounts for 0.1 to 0.4 parts by weight. The carbides account for 0.1 to 0.4 parts by weight. The particle size of the permanent magnetic alloy powders is 10 μm to 70 μm, and the grain size of NdFeB phase in the permanent magnetic alloy powders is less than 5 μm. Through the selection of alloy material ratio and manufacturing process, the processability and formability of permanent magnetic alloy materials can be effectively improved, suitable for metal injection molding and 3D printing production.

Abstract: Provided is a forming method of a metal layer suitable for a 3D printing process. The method includes the steps of providing a plurality of metal particles on a substrate; applying an oxide-removing agent to the metal particles to remove metal oxides on the metal particles; at a first temperature, performing a first heat treatment on the metal particles for which the metal oxides are removed to form a near shape; and at a second temperature, performing a second heat treatment on the near shape to form a sintered body. The first temperature is lower than the second temperature.

Abstract: Provided is a forming method of a metal layer suitable for a 3D printing process. The method includes the steps of (1) providing first metal particles on a substrate to form a first layer; (2) performing a first pre-heat treatment on the first layer; (3) applying an oxide-removing agent on selected first metal particles in the first layer to remove metal oxides; (4) providing second metal particles on the first layer to form a second layer; (5) performing a second pre-heat treatment on the second layer; (6) applying the oxide-removing agent on selected second metal particles in the second layer to remove metal oxides; repeating (1) to (6) until a latent part is formed; performing a first heat treatment on the first and second metal particles of the latent part to form a near shape; and performing a second heat treatment on the near shape to form a sintered body.
