Embodiment 1

[0030] S1. Preparation: 80 copies of TPX, 15 copies of PLA, 3 copies of TPU, and 1 copy of Sumilizer GM;

[0031] S2. Dry TPX at 110°C to a water content of 0.02%;

[0032] S3, TPX is preheated at 220℃;

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

[0034] S5, adding PLA to the second stage and extruding and granulating the mixture obtained from S3, the control temperature is 240~280℃, the rotation speed is 120~140r / pm, the injection pressure is 45~55MPa, and the residence time of the whole extrusion process is 1~280℃. 2 minutes, pull the thread to get the product.

Embodiment 2

[0036] 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] 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 invention relates to 3D printing, and proposes a 3D printing TPX composite material suitable for medical treatment and aviation, comprising the following components according to parts by weight: 70-90 parts of TPX, 10-20 parts of PLA, 1-5 parts of TPU, and Sumilizer GM 0.1 to 2 servings. Through the above technical solutions, the problem that the 3D printing materials in the prior art cannot simultaneously achieve light weight, high strength, and skin-friendly properties 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. 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 the 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 a certain extent, the development of materials determines whether 3D printing can have wider applications. At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, metal materials and ceramic materi...
