REVIEW ON DESIGN AND ADDITIVE MANUFACTURING OF CELLULAR LATTICE STRUCTURES BY EXTRUSION TECHNOLOGIES.

Additive manufacturing technology which started as a prototyping application in the infant stage for new product design and development is gaining importance by transforming into a realistic part manufacturing innovative opportunity. Basically additive manufacturing for cellular lattice structure manufacturing is a latest addition for benefitting from strength to weight ratio for better functional performance of parts. In this paper various types of lattice structure, computer aided design for AM, different methods to create cellular structures, functionally graded cellular structures in AM, stress based structural optimization method for light weight designing, and manufacturing and testing of lattice structure were considered as basis for further research in this area.
