Embodiment Construction

[0022] like figure 1 As shown, in one embodiment of the present invention, the processing method of 3D material comprises the following steps:

[0023] 1) styrene-butadiene copolymer is transported in the shearing machine 2 from feed inlet 1, and the columnar styrene-butadiene copolymer is sheared into uniform 0.2cm granular shape by shearing machine 2, Ensure that the subsequent swelling and softening time of styrene-butadiene copolymer is controllable, preventing excessive softening of some particles or incomplete softening of some particles;

[0024] 2) The granular styrene-butadiene copolymer is transported into the swelling tank 3, and the styrene-butadiene copolymer is swollen and softened by the solvent in the swelling tank 3, and the softening temperature is 110° C. The time is 45min-60min, softening can facilitate the subsequent grinding of styrene-butadiene copolymer;

[0025] 3) The softened styrene-butadiene copolymer is transported to the colloid mill 4 at a spe...

Abstract

The invention provides a treatment method of a 3D material. According to the method, a styrene-butadiene copolymer is adopted as a 3D printing material, and is subjected to shearing, swelling, softening, grinding, air-drying granulation and cooling treatment, so that the strength requirement of a printed finished product can be met, and the forming speed of the printed finished product can be increased.

Description

technical field [0001] The invention relates to the field of 3D materials, in particular to a 3D material processing method that utilizes styrene-butadiene copolymer as a 3D printing material and processes the material to improve the quality of 3D printing. Background technique [0002] In recent years, 3D printing technology has been gradually applied to the manufacture of actual products, among which the 3D printing technology of metal materials has developed particularly rapidly. Metal powders used in 3D printing generally require high purity, good sphericity, narrow particle size distribution, and low oxygen content. At present, the metal powder materials used in 3D printing mainly include titanium alloys, cobalt-chromium alloys, stainless steel and aluminum alloy materials, in addition to gold, silver and other precious metal powder materials used for printing jewelry. [0003] With the application of metal materials in the field of 3D printing, the disadvantages of 3D...
