Embodiment

[0026] An extruded 3D white marble powder printing slurry in this embodiment has a solid content of 90% and consists of the following components:

[0027]

[0028] Wherein, the kaolin powder is calcined and ground at a high temperature of 850-1000 degrees Celsius, and its particle size is 1250-1500 mesh, the particle size of white marble powder is 300 mesh, and the particle size of quartz powder is 1500-2000 mesh. The sodium tripolyphosphate is purchased from the market, and its viscosity ranges from 2000 to 2500 mPa·s.

[0029] The preparation method of present embodiment slurry is as follows:

[0030] (0) The white marble powder was wet-milled for 2 hours with a ball mill and a dispersion medium until the particle size was 300 mesh;

[0031] (1) Get 60g white marble powder, 10g kaolin powder and 25g quartz powder and mix them with a mixer for 4 hours until uniformly mixed to obtain mixed powder A;

[0032] (2) Add 0.6g sodium tripolyphosphate, 3g sodium silicate and 1.4...

Abstract

The invention discloses an extrusion type 3D white marble powder printing slurry and a preparation method thereof. The slurry of the invention has high solid content and good shear performance, and is suitable for extrusion 3D printing technology. At room temperature, it can gradually dry and solidify during the 3D printing process, so as to obtain high-precision molded parts without collapse.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a slurry for extruding 3D white marble powder printing and a preparation method thereof. Background technique [0002] 3D printing technology, also known as additive manufacturing, originated from the photographic sculpture and landform modeling technology researched in the United States more than 100 years ago, and it took shape in the 1980s. In the past thirty years, with the advancement of computer, laser technology, and material science, additive manufacturing technology has developed rapidly and is a representative technology in advanced manufacturing. Countries all over the world have regarded additive manufacturing as a new growth point for future industries, and additive manufacturing is also a breakthrough direction for various manufacturing powers to develop next-generation advanced manufacturing technologies. Additive manufacturing has the unique advan...
