Description

Technical Field

[0001] The invention relates to aging test equipment, in particular to an FDM module aging test equipment. Background Art

[0002] FDM (Fused Deposition Modeling) process The fused deposition manufacturing (FDM) process was successfully developed by American scholar Scott Crump in 1988. The materials of FDM are generally thermoplastic materials, such as wax, ABS, nylon, etc. The materials are fed in filaments. The materials are heated and melted in the nozzle, and the nozzle moves along the cross-sectional contour and filling trajectory of the part, while extruding the molten material, and the material solidifies rapidly and condenses with the surrounding materials.

[0003] As a 3D printing technology, FDM technology itself has become more and more popular in the industrial field, ensuring the long-term performance and reliability of printed parts has become particularly important. Therefore, aging test equipment for FDM printed parts has emerged, aiming to simulate and accelerate various environmental stresses that these parts may encounter in actual use, such as temperature cycles, humidity, etc., in order to evaluate and improve their long-term stability. The original intention of inventing such testing equipment is likely to respond to the following industry needs: 1. Quality control: As FDM parts are increasingly used in aerospace, automotive, medical and other fields, the requirements for component durability and reliability are becoming more and more stringent. 2. Material research and development: The continuous emergence of new materials requires corresponding testing methods to verify their performance under long-term use conditions. 3. Standard setting: Industry standardization organizations may promote aging testing as a necessary link to certify that FDM products meet specific performance standards.

[0004] Traditional aging test equipment can only perform aging tests on one module product. Even if it can perform aging tests on multiple module products at the same time, since each module product is in a different position in the test equipment, it is impossible to ensure the consistency of the test environment of the module products in the same batch of tests, resulting in poor test results for the same batch of modules.
