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: A polymer is disclosed, which includes a structure of Formula 1 or Formula 2. R1 is a C2-18 alkylene group or a C6-18 arylene group, R2 is a C1-18 alkyl group, and R3 is a functional group of Formula 3. Each of X1, X2, X3, X4, X5, and X6, being the same or different, is H or methyl. Each of p, q, and r, being the same or different, is an integer of 1 to 60. R4 is —C2H4—, —C3H6—, Each of m and n, being the same or different, is an integer of 0 to 50, and m+n≠0.

Abstract: An ink is provided, which includes a resin, UV curable monomer, and photo initiator. The resin is formed by reacting a plurality of end capping agents with a dendrimer compound in an environment including esterification catalyst, inhibitor, and first solvent. The dendrimer compound is formed by reacting a multi-hydroxy compound and a plurality of hydroxy-containing epoxy compounds in an environment including alkaline catalyst and second solvent. The multi-hydroxy compound and the hydroxy-containing epoxy compounds have a molar ratio of 1:6 to 1:20, and the multi-hydroxy compound and the end capping agents have a molar ratio of 1:6 to 1:20. The end capping agents include acrylic acid, methacrylic acid, glycidyl methacrylate, or 2-amino acrylic acid. The resin and the UV curable monomer have a weight ratio of 100:30 to 100:5000, and the resin and the photo initiator have a weight ratio of 100:30 to 100:500.

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.
