Embodiment 1

[0030] S1. Material preparation: 80 parts of TPX, 15 parts of PLA, 3 parts of TPU, 1 part of Sumilizer GM;

[0031] S2, drying the TPX at 110°C until the water content is 0.02%;

[0032] S3, TPX is preheated at 220°C;

[0033] S4. Put TPU, Sumilizer GM and preheated TPX into the first stage of the extruder to extrude. The temperature is controlled at 240-280°C, the speed is 80-100r / pm, and the injection pressure is 50-60MPa;

[0034] S5. Add PLA to the second stage and extrude and granulate the mixed material obtained in S3. The temperature is controlled at 240-280°C, the rotation speed is 120-140r / pm, the injection pressure is 45-55MPa, and the residence time of the entire extrusion process is 1-280°C. After 2 minutes, pull the wire to get the product.

Embodiment 2

[0036] Material preparation: 70 parts of TPX, 10 parts of PLA, 1 part of TPU, 0.1 part of Sumilizer GM, the preparation method is the same as that of Example 1.

Embodiment 3

[0038] Material preparation: 90 parts of TPX, 20 parts of PLA, 5 parts of TPU, 2 parts of Sumilizer GM, the preparation method is the same as that of Example 1.

Abstract

The present invention relates to 3D printing, and provides a 3D-printing TPX composite material suitable for medical treatment and aviation. The 3D printing TPX composite material comprises the following components by weight: 70-90 parts of TPX, 10-20 parts of PLA, 1-5 parts of TPU, and 0.1-2 parts of Sumilizer GM. By means of the above technical scheme, the problem that a 3D printing material in the prior art cannot achieve light weight, high strength and skin friendliness at the same time is solved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing TPX composite material suitable for medical treatment and aviation and a preparation method thereof. Background technique [0002] Compared with traditional manufacturing technology, 3D printing technology greatly reduces the processing steps and shortens the processing cycle, and the more complex the structure of the product, the more significant its manufacturing efficiency is. 3D printing technology will revolutionize not only the development and manufacturing stages, but also logistics and sales. [0003] However, 3D printing materials are an important material basis for the development of 3D printing technology. To some extent, the development of materials determines whether 3D printing can be used more widely. At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, metal materials and ceramic materia...
