Problems solved by technology

At present, the most commonly used organic polymer materials for 3D printing are nylon, ABS resin, polycarbonate, polyphenylene sulfone, etc. These materials require high temperature when molding, not only the molding speed is slow, but also the finished product has excellent properties such as strength and toughness. Poor aspect, single color
In contrast, the development of other 3D printing materials is very rare, which also limits the practicability and universality of 3D printing

Embodiment 1

[0071] A kind of composition for 3D printing, its each component except solvent is recorded as according to weight part:

[0072]

[0073] The above composition was gradually added to 100 parts of dichloromethane under nitrogen protection and a stirring speed of 300rpm. After the addition was completed, the stirring was continued for 20 minutes, and then sealed and stored away from light. After being placed for more than 12 months, it could still be used continuously.

Embodiment 2

[0075] A kind of composition for 3D printing, its each component except solvent is recorded as according to weight part:

[0076]

[0077]

[0078] The components of the above composition were gradually added to 100 parts of dichloromethane under nitrogen protection and a stirring speed of 300 rpm, and continued to stir for 30 minutes after the addition, and then sealed and stored away from light to obtain a pink color for 3D printing. combination.

[0079] The above materials are combined with other yellow, blue, and black materials, and the temperature of the printing cavity is controlled at 50°C, and the relative humidity is 45%, etc., to obtain colorful 3D printed products.

Embodiment 3

[0081] A kind of composition for 3D printing, its each component except solvent is recorded as according to weight part:

[0082]

[0083] The components of the above composition were gradually added to 120 parts of dioxane under the condition of nitrogen protection and a stirring speed of 300 rpm, and continued to stir for 30 minutes after the addition, and then sealed and stored away from light.

[0084] Using Z Corporation's Z402 printer (need to add humidity control components, control the temperature of the printing chamber to be 30°C and the relative humidity to be 45%), the above composition materials can print out polymer products with high mechanical strength and conductivity.

Abstract

The invention discloses a 3D printing composition, its preparation and application methods and a product thereof. According to the material, cyanoacrylate and a powder material are used as main bodies; a solvent is added to adjust fluidity of the material; and simultaneously, certain amounts of a plasticizer, a thickener, a flexibilizer, a stabilizer, a cross-linking agent, a pigment, a degassing agent and the like are contained to raise stability of the material and mechanical property of a printing product. As the material is a liquid and solidification process of the material is controlled by controlling conditions such as environment humidity, temperature and the like during printing, an ink-jet printing head which has been developed comparatively mature at present can be used for printing. The composition provided by the invention has characteristics of high printing precision, fast forming speed and low cost. Meanwhile, a printing product has high mechanical strength. The composition is a novel green 3D printing material.

Description

technical field [0001] The present invention relates to a composition that can be used for 3D printing, its preparation and use methods and products. Background technique [0002] Additive manufacturing technology, also known as 3D printing, refers to the technology of accumulating materials layer by layer to manufacture physical parts through CAD design data and computer control throughout the process. Additive manufacturing technology does not require traditional tools, fixtures, and multiple processing procedures. Using 3D design data, parts of arbitrary complex shapes can be quickly and accurately manufactured on one device, thereby realizing "free manufacturing" and solving many problems that were difficult in the past. The forming of complex structural parts manufactured can greatly reduce the processing steps and shorten the processing cycle. And the more complicated the structure of the product, the more significant the effect of its manufacturing speed. [0003] A...
