Editorial: Additive manufacturing for polymers

Additive manufacturing (AM), also known as 3D printing, is a kind of technology that manufactures 15 solid parts based on a 3D model (CAD model) with a layer-by-layer accumulation of materials, which 16 allows AM to make flexible and customized designs of product structures and to quickly and accurately 17 transform design ideas into prototypes or even parts to shorten time-to-market and reduce costs, with 18 irreplaceable advantages in the manufacture of complex structural characteristics and the delicate 19 design of component structures. However, there are still many limitations in the development of 20 polymer 3D printing, such as the restricted available materials, and the mechanical strength of the 21 products still needs to be higher than those produced by traditional methods. Filament Fabrication parameters on the strength of Ti-6Al-4V/PA-CF joints produced by this process 56 combination using a three-point bending test method. The data analysis indicated that the printing 57 speed was the main parameter affecting the joint strength, followed by the inclination angle, with the 58 coating height exhibiting only a minor effect. 59The In conclusion, this research topic presented insightful and innovative reports focusing on the polymer 76 AM technique, promoting the development of this field. We sincerely thank all authors and reviewers 77 for contributing to this research topic.
