The invention belongs to the technical field of
metal material additive manufacturing, and particularly relates to a manufacturing process of a silver-
germanium infrared health-care ornament, which comprises the following steps: firstly, uniformly mixing
Ag alloy powder and Ge
powder, and then obtaining a
green body of which the shape completely conforms to a pre-designed 3D pattern by adopting an
adhesive spraying 3D printing
metal forming technology; and
degreasing and
sintering to obtain a silver-
germanium sintered part, and finally carrying out molding post-
processing to finally obtain the finished product silver-
germanium ornament. The defects that in the germanium-silver
alloy machining process, materials are large in
brittleness, high in
hardness, poor in flexibility and
ductility, prone to brittle failure and scrapping and difficult to
machine into delicate and exquisite products are overcome; and the 3D printing technology is applied to design and manufacturing of germanium-silver
ornaments, one-time forming of complex three-dimensional design products is achieved, the design feasibility of germanium-silver products is greatly widened, and the germanium-silver
ornaments have great application value when being applied to health-care products such as
ornaments, waistbands, neck bands, bracelets, kneecaps and pillows.
