Mechanical Characterization and Process Optimization of PolyJet 3D Printing Using Digital ABS with Different Part Geometries
Last few decades have seen a rapid growth in additive manufacturing (AM) owing to its adaptability to new manufacturing requirement and trends. In PolyJet technology, a popular method in AM, parts are manufactured by depositing layer upon layer and, simultaneously, each layer is cured using ultraviolet energy. This process exhibits the structured approach of layered manufacturing process which produces state-of-the-art products with superior quality. The process has shown promising technological development in the field of design and manufacturing. This work aims at improving the performance characteristic and process optimization through the application of design of experiment approach. The response parameters viz. the storage modulus, loss modulus, loss factor, glass transition temperature, and surface roughness have been individually assessed. The statistical technique has been used to study the effect of process parameters and their significance. Gray relation grade analysis has been used for process optimization.
