Abstract

The invention relates to the field of 3D printing, in particular to a colorful mini type FDM 3D printing material and a preparation method thereof. Printing wires of the same FDM thermoplastic material contain different mixing modes of three colors, namely red, yellow and blue, and exhibit in multiple colors. The red colored part of each printing wire is 0.5-10 cm in length, and the gap is 10-0.5 cm; the yellow colored part of each printing wire is 0.5-10 cm; the mentioned units are colored sequentially and alternately. The colorful FDM 3D printing material has the advantages that the colorful mini type printing material is subjected to effective coloring treatment, the different combination modes of the three colors, namely red, yellow and blue, are adopted, after the 3D FDM material is subjected to melt extrusion through a spray head, different colors are exhibited, the color layer scope can be controlled, and a print model is made to be more attractive and beautiful; meanwhile, the material is convenient to use, wire replacement is not needed, the machine failure rate is low, and the material has wide application prospect in the markets of child education and family education and in the development and guiding processes of enlightenment and creative thinking.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a colorful mini-type FDM 3D printing material and a preparation method thereof. Background technique [0002] The development of 3D printing technology and the development of 3D printing materials is one of the three key technologies of 3D printing technology. Among them, 3D printing consumables are the bottleneck of the development of the industry. The printing technology of FDM molten molding material will be directly applied to thousands of households. How to make the material print smoothly, the printing model is more attractive, beautiful, bright in color, the printing process is environmentally friendly and the printing material can be pollution-free has become the focus of everyone's attention. [0003] In traditional 3D printing, if the color needs to be changed, the machine must be paused, the filament is withdrawn, and then the filament is fed and re-printed. If you need co...
