Additive manufacturing refers to the technique of building an object layer by layer from their digital CAD drawing. It is possible to manufacture complex shape and small parts of multiple structure. One of the additive manufacturing type is Fused Deposition Modelling which deposits semi-molten thermoplastic polymer on to the bed to build up the objects directly from the designed CAD drawing. With this advantages, Fused Deposition Modelling machine has attracted attention from many industries to manufactured complex lattice structured. In theory, lattice design offered lightweight structure with equivalent of better mechanical performance compare to traditional solid design. However geometrical and dimensional imperfection in structure will affect the mechanical performances of the lattice design. As a key current issue of Fused Deposition Modelling process is related to geometrical deviational and dimensional accuracy of the manufactured product, it is a challenging task for this additive manufacturing technique to fabricate a complex lattice structure at a required optimum condition. Therefore, the capability of Fused Deposition Modelling machine in manufacturing complex lattice structure will be investigated. Two lattice design with various dimension will be manufactured. Optimization statistical Taguchi method will be implemented in this work. Main effect analysis and signal to noise (S/N) ratio will also been studied
