Abstract
In this paper, a case of space high-precision THz antennas based on 3D printing technology in engineering has been proposed. The reflectors and the supporting structure have been printed in an integrated way by adopting the structural optimization design method suitable for the high-precision 3D printing process and using the honeycomb structure in the low-stress area. This can avoid the assembly error caused by the assembly of various components of the antenna and achieve the goal of integrated, high-precision, lightweight, and high-thermal stability 3D printing, and manufacturing, which provides an idea for high-precision manufacturing of 3D printing technology in space-borne THz devices.
