In this study， the feasibility of applying the lattice structure fabricated by selective laser melting to drilling tools is analyzed. The development status of lunar drilling sampling tools， the lightweight 3D metal lattice structures and the basic methods and advantages of selective laser melting technology are summarized. It is proposed to apply the 3D lattice structure to manufacture lightweight lunar drilling sampling tools with selective laser melting manufacturing technology. The adaptability of the drilling tools of the lattice structure to the lunar drilling process is discussed and the development trend of lightweight lunar drilling tools is envisioned. The analysis shows that the 3D lattice structure prepared by selective laser melting has great application potential in lunar drilling sampling tools.
