EVOLUTION IN MANUFACTURING OF GRID STIFFENED STRUCTURES THROUGH CAM AND ADDITIVE TECHNIQUES

In this review paper, a comparison is drawn among different manufacturing grid stiffened structures, i.e., isogrid panels manufactured using non-conventional manufacturing techniques such as Fused Deposition Modeling (FDM) over existing conventional methods such as milling; by summarizing existing success analyses. These Isogrids/Grid stiffened structures are primarily building blocks used in aerospace applications such as rocket shells, satellites, space station walls, and other structures requiring additional strengthening such as armour shells and wall structures mega buildings such as stadiums, domes, or even spider webs. A comprehensive analysis is made for various aspects of these advantages and the role of non-conventional techniques is discussed. Moreover, a hypothesis is put forward regarding design optimization and evolution in the future. The isogrids are an upcoming research area that has the capacity to strengthen the aerospace, nuclear and other allied sectors
