Embodiment 1

[0022] Ink for printing stainless steel products. The mass ratio is 1.5% polyvinyl alcohol 1799, 0.5% polyacrylic acid, polymethacrylic acid copolymer, 50% distilled water, 48% 316L stainless steel powder. Dissolve 1.5% polyvinyl alcohol 1799, 0.5% polyacrylic acid and polymethacrylic acid copolymer in 50% distilled water at 65°C, stir evenly, add 48% 316L stainless steel powder by mass, and stir evenly to obtain printed stainless steel products water-soluble ink. This ink is used for 3D inkjet printers to print designed products. During the printing process, the printing chamber is heated to 115°C to evaporate the water in the ink, and at the same time, each layer of the printed product is plasticized, and the designed molded product is printed. . The molded product is vacuum removed at 210°C for 8 hours to remove polyvinyl alcohol 1799; the temperature is raised to 310°C for 6 hours to remove polyacrylic acid and polymethacrylic acid copolymer. Raise the temperature to 13...

Embodiment 2

[0024] Ink for printing ceramics. The mass ratio is 2% caprolactam, 0.5% polymaleic anhydride, 65% distilled water, and 32.5% zirconia powder. Dissolve the mass ratio of 2% caprolactam and 0.5% polymaleic anhydride in 65% distilled water at 70°C, stir evenly, add 32.5% zirconia powder, and stir evenly to obtain a water-soluble ink for printing zirconia products. This ink is used for 3D inkjet printers to print designed products. During the printing process, the printing chamber is heated to 115°C to evaporate the water in the ink, and at the same time, each layer of the printed product is plasticized, and the designed molded product is printed. . The molded product is vacuum removed at 230°C for 8 hours to remove caprolactam; the temperature is raised to 310°C for 6 hours to remove polymaleic anhydride. The temperature was raised to 1550°C and sintered for 8 hours to obtain printed ceramic products.

Abstract

The invention discloses a water-soluble ink for printing a metal product, a ceramic product and a product made of a metal and ceramic composite material, as well as a method for obtaining a product made of a required material by plasticizing, unsticking and sintering a molding product printed by the ink. The ink comprises components in mass ratio as follows: 30%-70% of material components, 1%-9% of high polymer material components and 69%-21% of water, wherein the material components include metal, alloy, ceramic and the like, and the high polymer material components include one or more of caprolactam, 2-pyrrolidone, polytrimethylene terephthalate, polybutylene terephthalate, poly(ethylene glycol) diacrylate, dipropylene glycol methyl ether acetate, phthalic anhydride, phthalimide, polyacrylamide, polyacrylic polymethacrylic acid and copolymer thereof, polyvinyl alcohol, polyethylene glycol, polyoxyethylene, polyvinyl pyrrolidone, polymaleic anhydride, KEPS resin, poly dimethyl diallyl ammonium chloride, water-soluble cellulose, single-stranded polyurethane and the like.

Description

technical field [0001] The invention relates to a water-soluble ink for manufacturing metal, ceramic and composite (mixed) material products by using three-dimensional printing technology. The molded products printed with this ink are evaporated, plasticized, debonded, and sintered to obtain products of required materials. Background technique [0002] Type the technical field description paragraph here. 3D printing is currently a very popular new digital manufacturing technology. The popular 3D printing technologies in the market now include: 3DP technology; FDM fusion lamination molding technology; SLA stereolithography technology; SLS selective laser sintering technology; DLP laser molding technology; UV ultraviolet molding technology, etc. [0003] 3D printers using 3DP technology use standard inkjet printing technology to create three-dimensional solid products by laying liquid joints on a thin layer of powder and creating each part layer by layer by printing cross-se...
