New Perspective of Additive Manufacturing: From Materials to Processes and Algorithms of Continuous Carbon Fiber-Reinforced Composites.

High-strength and lightweight products have always been the dream of human beings, especially today when energy resources are increasingly depleted. Although additive manufacturing provides us with possibilities, for now, most researchers focus on reinforcing existing printing materials, improving printing processes, and updating algorithms to improve product performance. However, in the statistical classification of this work, these are only a small range of one kind of statistics. This work reviews the key factors of additive manufacturing from materials to processes and algorithms from a new perspective, to get rid of the inherent thinking mode and provide unique ideas. With the idea of "everything is printed," this article emulates nature's "make the most of everything." First, anisotropic materials and the solution of the weak interfacial properties are described. Second, the energy point of view through the process, in space (points, lines, planes, etc.), to summarize the classification and time division of series and parallel printing. Finally, the classification of current hierarchical printing algorithms and the expectation of future spatial printing algorithms are indicated. This article takes the key factors of continuous carbon fiber composite 3D printing as the main line, and provides certain reference for the future development of additive manufacturing from a new perspective.
