Abstract Scope |
Material is stacked in a layered manner to build objects with complex three-dimensional (3D)geometry shapes using most additive manufacturing processes. However, the way of material is deposited to create parts has a significant impact on the mechanical performance of printed 3D structures. In specific, 3D printed materials show anisotropic mechanical properties, which are determined by printing orientations. To overcome this bottleneck, a novel structural beam-based ultra-fast volumetric 3D printing, inspired by the plant growth in nature, was thereby developed. Such a process features constructing desired geometry continuously by direct manipulation of the optical field in 3D space, where the photopolymerization occurs consistently in all directions. The mechanical properties of printed parts were fully investigated and further modulated by adjusting printing parameters. The proposed technology enables the construction of 3D structures with isotropic mechanical properties and opens intriguing perspectives for mass production using advanced printing technology. |
