Embodiment 1
[0032] The preparation method of the liquid metal-based lattice structure metamaterial of this embodiment includes the following steps:
[0033] S1, using waxy photosensitive resin to light-cure the lattice unit and combine it with DLP additive manufacturing process for 3D printing to obtain a waxy lattice unit model:
[0034] (1) Select the basic unit form of the lattice structure:
[0035] The lattice structure includes two types of lattices: truss and curved surface. Commonly used truss structures include Octet, BCC, FCC, etc., and curved surface lattice structures include Diamond, Primitive, etc. By evaluating the mechanical failure mode of connection points such as trusses and curved surfaces after loading, it can be judged whether it can be used to prepare liquid metal lattice structure metamaterials. If the main failure mode is tensile or fracture deformation, it is not suitable for the preparation of this preparation method. The present invention illustrates the prep...
