3D printing technology has achieved rapid development in recent years, and is widely used in manufacturing, medical treatment, construction and other fields. However, the brittleness of 3D printing wire in high temperature environment has been an important bottleneck affecting its application range. In order to improve the performance of 3D printing wire under high temperature conditions, it is particularly important to carry out high temperature brittleness test and take corresponding improvement measures.

First, you need to optimize the formula design of the 3D wire. Selecting raw materials with better high temperature resistance is the key to improve high temperature brittleness. For example, polylactic acid (PLA) materials tend to become brittle at high temperatures, while polyamide (PA, nylon) materials have better high-temperature resistance. By adjusting the material formula and increasing the proportion of high temperature resistant components, the high temperature stability of 3D wire can be effectively improved.

Secondly, strengthening the processing process control of wire is also an important means to improve the high temperature brittleness. In the production process, by precisely controlling extrusion temperature, cooling speed and other process parameters, the microstructure of the wire can be optimized and its ability to resist high temperature brittleness can be improved. In addition, appropriate post-treatment processes, such as annealing, can further eliminate residual stress inside the wire and enhance its stability in high temperature environments.

In addition, the application of surface treatment technology can also effectively improve the high temperature brittleness of 3D printer filament. By coating the surface of the wire with high temperature resistant coating, such as ceramic coating or silicone coating, it can effectively isolate the direct effect of high temperature environment on the wire and reduce the brittleness of the wire at high temperature. At the same time, the surface treatment can also improve the oxidation resistance of the wire and extend its service life in high temperature environment.

Finally, the establishment of a perfect high temperature brittleness test system is an important guarantee for improving the high temperature performance of 3D wire. By simulating the actual use environment, high temperature tensile test, high temperature impact test, etc., to comprehensively evaluate the performance of the wire under high temperature conditions. According to the test results, the formula and processing technology of the wire are continuously optimized to improve its reliability in high temperature environment.

To sum up, improving the high temperature brittleness of 3D wire requires comprehensive consideration from many aspects such as formula design, processing technology, surface treatment and test system. By taking a series of effective measures, the performance of 3D wire under high temperature conditions can be significantly improved, and its application range in high temperature environments such as aerospace and automobile manufacturing can be further expanded.
