[0002] Additive manufacturing is a manufacturing technology that builds objects by stacking materials layer by layer, as opposed to traditional methods of cutting or removing material.

This makes additive manufacturing ideal for manufacturing complex geometries and customized parts.

[0003] The micro-truss structure is generally composed of two layers of skin and a beam matrix structure in the middle. The upper and lower layers of skin play the role of dispersing the load, and the main load is borne by the beam matrix structure in the middle. The unit cell of the beam matrix structure is a plane or space structure with triangular units composed of straight rods. The axial tension or pressure is mainly borne by the rods, thereby making full use of the strength of the material, saving materials, reducing dead weight and increasing stiffness.
