Abstract

The invention discloses a PLA fragrant wire rod for 3D printing. The PLA fragrant wire rod is prepared from the following raw materials in percentage by mass: 0.5 to 1.1 percent of white oil, 1.5 to 2.5 percent of microcapsule flavoring agent, 4 to 6 percent of color master batch, 2 to 4 percent of flexibilizer and the balance of PLA. The invention discloses a preparation method of the PLA fragrant wire rod, which comprises the following steps: uniformly mixing the PLA and the white oil, adding the microcapsule flavoring agent, uniformly mixing the raw materials, putting the raw materials into a double-screw extruder, extruding and granulating the mixture at 160-190 DEG C, and drying the granules to obtain fragrant PLA master batches; then, uniformly mixing the PLA with the fragrant PLA master batch, the flexibilizer and the color master batch, putting the mixture into a single-screw extruder, extruding the mixture at 160-200 DEG C, and cooling the mixture to obtain the PLA fragrant wire rod. The invention further discloses a use method of the PLA fragrant wire rod, in which the PLA fragrant wire rod is put into an FDM printer for printing, and the printing temperature is 200-230 DEG C.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a PLA scented wire used for 3D printing and its preparation method and application. Background technique [0002] 3D printing (especially material extrusion 3D printing technology represented by FDM / FFF) has been widely used in industrial design, medical protective gear, aerospace, automobile assembly, education, entertainment and other industries. Material extrusion 3D printing technology has the advantages of low cost, simple operation, and non-toxic and harmful production. [0003] Materials Commonly used materials for extrusion 3D printing include PLA, ABS, PETG, PC, PA, etc. Among them, PLA has been widely used because of its wide range of sources, low printing temperature, good biodegradability, and good printing and molding effects. At the same time, it has stable chemical stability and does not react with commonly used various toners, metal powders, and inorganic add...
