Abstract
Advancement in manufacturing technology, prototyping, machining etc. are concerned with material optimization, process optimization, financial optimization and sustainable development. The current review on characterization, applications and process study of various additive manufacturing (AM) processes deals with the systematic use of resources in product development. The comprehensive description on additive manufacturing techniques, its applications and needs are illustrated. The attempt is to diagnose the research gap in the process study and to forecast the new methodology and applications in the all the field like automobile, aerospace, biomedical etc. through AM. The tool making for friction stir welding purpose, complex geometries, etc. were fabricated without increasing the overall cost through AM techniques. The applications of AM techniques in composite based materials are also characterized. The comparative analysis between subtractive and additive manufacturing are highlighted and future scope is tried to identify.
