Embodiment 1

[0053] A new type of additive printing material, by weight percentage, comprising: 84.4% aliphatic polyurethane; 0.8% water-based defoamer; 0.6% wetting agent; 0.5% leveling agent; 2.8% dispersant; 5.9% pigment; and The water-based curing agent is 5%. The new additive printing material has a viscosity value of 98000 cps after testing.

[0054] Use the PET flat base cloth as the base of 3D printing, put an appropriate amount of the new additive printing material provided in this embodiment into the ink cartridge of the ceramic 3D printing device, and add a suitable after the outlet of the ink cartridge. Matched caliber screw extruder. Design the three-dimensional pattern model to be 3D printed as a musical note The line model of the design model file is sliced ​​and sent to the 3D printing control host. Set the 3D printing working parameters, specifically, set the size of the printing needle nozzle to 0.8mm, the printing line width to 0.5mm, the distance between the substrat...

Embodiment 2

[0056] The difference from Example 1 is that the new additive printing material provided in this example contains, by weight percentage: 83.1% of aliphatic polyurethane; 0.8% of water-based defoamer; 0.6% of wetting agent; leveling agent 0.5%; 3% dispersant; 2% pigment red, 5% pigment yellow; and 5% water-based curing agent. After testing, the new additive printing material has a viscosity of 100,000 cps.

[0057] Using polyester-spandex blended flat fabric as the base for 3D printing, put an appropriate amount of the new additive printing material provided in this embodiment into the ink cartridge of the ceramic 3D printing device, and add a Suitable diameter screw extruder. Design the three-dimensional pattern model to be 3D printed as an irregular leveling pattern model, slice the design model file, and send it to the 3D printing control host. Set the working parameters of 3D printing, specifically, set the size of the printing needle nozzle to 1.2mm, the printing line wid...

Embodiment 3

[0059] The difference from Example 2 is that the new additive printing material provided in this example contains, by weight percentage: 78% of aliphatic polyurethane; 1.2% of water-based defoamer; 0.8% of wetting agent; 0.8% of leveling agent %; 5.2% of dispersant; 4% of pigment red, 4% of pigment yellow; and 6% of water-based curing agent. After testing, the new additive printing material has a viscosity value of 96000cps.

[0060] In this embodiment, the three-dimensional pattern model to be 3D printed is designed as a vamp model with a special pattern design. Set the working parameters of 3D printing, specifically, set the size of the printing needle nozzle to 1.2mm, the printing line width to 0.1mm, the distance between the substrate and the printing needle nozzle to 5mm, the compressed air pressure to 0.1mPa, and the viscous fluid to advance evenly The propulsion magnification (extrusion magnification) of the device (screw extruder) is 0.5 times, the retraction length is...

Abstract

The invention belongs to the technical field of 3D additive printing materials, and particularly relates to a novel additive printing material and application thereof in ceramic 3D printing equipment. A 3D model with the line effect and the thickness higher than 10 mm can be printed by utilizing the material, the 3D model has the excellent natural leveling effect of the novel additive printing material, no wiredrawing or rough edge exists, and the effects cannot be achieved through conventional printing processes such as silk-screen printing and transfer printing technologies for the same material at present. The application mode of a traditional ceramic 3D printer is expanded, a viscous substance propeller is innovatively combined to conduct shearing, stirring and propelling at the same time, it is avoided that printing materials are too high in viscosity to block a printing needle nozzle, and the printing materials are discharged more evenly and smoothly. The application is that the disclosed printing material can play a good connection role between the same or different interfaces, and a wider application way for the novel additive printing material in the fields of textiles, clothes, shoe materials, bags, furniture and the like is provided.

Description

technical field [0001] The invention belongs to the technical field of 3D additive printing materials, and more specifically relates to a novel additive printing material and its application in ceramic 3D printing equipment. Background technique [0002] Additive Manufacturing (AM), commonly known as 3D printing, integrates computer-aided design, material processing and molding technology, based on digital model files, through software and numerical control system, special metal materials, non-metal materials and medical biological materials, According to extrusion, sintering, melting, photo-curing, spraying and other methods, it is piled up layer by layer to produce physical objects. Compared with the traditional processing mode of raw material removal-cutting and assembly, it is a "bottom-up" manufacturing method through material accumulation to realize the manufacturing process of items from scratch. This makes it possible to manufacture complex structural parts that wer...
