Embodiment 1

[0024] Example 1 Dissolve 10 mg of 4,7-dithienylbenzothiadiazole and orange fluorescent material in 50 ml of dichloromethane solvent and mix well to obtain 4,7-dithienylbenzothiadiazole orange For organic fluorescent dyes, apply the solution to PLA filaments. Be careful to keep the PLA filaments separate from each other to avoid sticking together after application. PLA filaments containing orange organic fluorescent dyes are available (see figure 1 ).

Embodiment 2

[0026] Dissolve 10 mg of 4,7-bithienylbenzothiadiazole, an orange fluorescent material in 50 ml of dichloromethane solvent, and mix well to obtain 4,7-bithienylbenzothiadiazole orange organic fluorescent dye. Evenly soak the PLA wire into a large beaker filled with organic fluorescent dyes. After soaking completely for 10S, the PLA wires are taken out, and the PLA wires are separated from each other to avoid bonding to each other, and the PLA wires containing orange organic fluorescent dyes are obtained (see figure 2 ).

Embodiment 3

[0028] Dissolve 10mg of 4,7-dithienylbenzothiadiazole and orange fluorescent material in 50 ml of dichloromethane solvent, and mix well to obtain 4,7-dithienylbenzothiadiazole orange organic fluorescent dye. The solution is applied to the PLA wire to obtain the PLA wire coated with the orange organic fluorescent dye. A hollow cube three-dimensional figure with dimensions of 4.2cm in length, 4.2cm in width, and 4cm in height, with a wall thickness of 0.1cm will be designed by computer, processed in layers and sliced, and imported into a 3D printer. The printing consumables use PLA filament coated with orange organic fluorescent dye. Place the hollow cube to be printed on the 3D printer station, and it is controlled by the computer for 3D printing. A PLA hollow cube structure stained with an orange organic fluorescent dye was obtained (see image 3 ).

Abstract

The invention discloses a 3D printing composite material containing an organic fluorescent dye and application thereof. The preparation method comprises the following steps: dissolving the organic fluorescent dye in an organic solvent, and then coating a printing piece with the organic fluorescent dye so as to obtain a PLA printing wire material dyed by the organic fluorescent dye. A 3D printer isused for printing the printing piece to obtain the 3D printing piece containing the organic fluorescent dye. Compared with an original PLA wire, the PLA wire with the organic fluorescent dye has thefluorescent effect, a product still has the fluorescent effect after being subjected to hot-melt printing through a 3D printer, a printing work containing the fluorescent dye can be self-luminous under the irradiation of an ultraviolet lamp, and the artistic performance of the 3D printing work is improved. The preparation method is simple, the operation is simple and convenient, the practicabilityis high, the performance of the dyed PLA wire is stable, the dyeing effect is uniform, the diameter of the wire is not increased, adverse effects on a 3D printer nozzle cannot be caused, and the 3D printing composite material is suitable for being used by an FDM (frequency division multiplexing) printer.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and specifically relates to a 3D printing composite material containing an organic fluorescent dye and its application. Background technique [0002] 3D printing technology is a rapid prototyping technology. According to the information in the digital model file, using polylactic acid, powdered bondable materials, etc. as raw materials, objects are constructed by layer-by-layer printing. At present, 3D printing manufacturing technology has been widely used in industrial design, architectural design, automobile, aerospace and medical equipment, and has a tendency to replace traditional manufacturing methods in some fields. 3D printing by extruding materials is currently the most popular and mature form of 3D printing. This method is used for material extrusion (FDM) 3D printers. FDM printers are low in price and cost, easy to maintain, easy to operate, and have broad application prospects. ...
