Embodiment 1

[0022] A kind of 3D printing powder, its raw material comprises by mass percentage:

[0023]

[0024] Further, the particle size of the talc powder is 150-800 mesh, and the particle size of the quartz stone powder is 150-800 mesh.

[0025] In the ingredients, increasing the proportion of talcum powder can improve the spreadability of the powder; increasing the proportion of quartz stone powder can improve the strength of the part (or model); as a binder, cellulose can be used to improve the part (or model) Toughness, but also improve its impact or vibration resistance; wetting agent is used to improve the wetting performance of powder and binder.

[0026] Simultaneously in the present invention, the size of raw material particle diameter has crucial effect to the production process of the printing powder of the present invention and final product, and raw material particle diameter is too small, the surface roughness of the part (or model) that is prepared into with powder ...

Embodiment 2

[0037] A kind of 3D printing powder, its raw material comprises by mass percentage:

[0038]

[0039] The wetting agent selected in this embodiment is ethanol.

[0040] Further, the particle size of the talc powder is 300 mesh, and the particle size of the quartz stone powder is 300 mesh.

[0041] The preparation method comprises the following steps:

[0042] (1) According to the corresponding ratio, the quartz stone powder and the particle diameter are mixed evenly with 250 mesh cellulose;

[0043] (2) Pour the wetting agent into the mixed material in step (1) and mix evenly;

[0044] (3) Pour the talcum powder into the mixed material in step (2) and mix evenly;

Embodiment 3

[0047] A kind of 3D printing powder, its raw material comprises by mass percentage:

[0048]

[0049] The wetting agent used in this example is prepared by mixing ethane and propane in a ratio of 1:1.

[0050] Further, the particle size of the talc powder is 300 mesh, and the particle size of the quartz stone powder is 300 mesh.

[0051] The preparation method comprises the following steps:

[0052] (1) According to the corresponding ratio, the quartz stone powder and the particle diameter are mixed evenly with 280 mesh cellulose;

[0053] (2) Pour the wetting agent into the mixed material in step (1) and mix evenly;

[0054] (3) Pour the talcum powder into the mixed material in step (2) and mix evenly;

[0055] (4) Seal the package to obtain the 3D printing powder of the embodiment.

Abstract

The invention provides 3D printing powder and a preparation method thereof, wherein the 3D printing powder comprises, by mass, 50-80% of talc powder, 15-45% of quartz stone powder, 3-5% of cellulose,and 0.8-1.3% of a wetting agent, wherein the particle sizes of the talc powder and the quartz stone powder are 150-800 mesh. According to the present invention, the 3D printing powder has characteristics of low cost, good toughness, high strength and excellent marketing value.

Description

technical field [0001] The invention relates to the technical field of 3D printing materials, in particular to a 3D printing powder and a preparation method thereof. Background technique [0002] The currently used 3D printing powders are polymer materials. The common ones are ABS, PC materials, PLA, nylon materials, etc. or ceramic powders, which are characterized by high prices. For example, the price of a plastic powder is as high as 1,500 yuan / kg. The performance is not ideal, the strength is low, easy to break, and the post-treatment process is complicated. Therefore, the price and performance of powder are the bottlenecks restricting the promotion of 3D printing technology. Contents of the invention [0003] Aiming at the problems of high cost and unsatisfactory performance of current 3D printing materials, the present invention provides a 3D printing powder with cheap and easy-to-obtain raw materials, simple preparation method and excellent performance and a prepar...
