Advances in Additive Manufacturing Processes in Achieving Productivity

Abstract

Additive Manufacturing which is also referred as three dimensional printing. Even though the technique has had remarkable improvements since its emergence over 25 years ago, still faces several technical challenges related to material characterization and availability compared with other conventional techniques.  This paper aims at investigating the impact of additive manufacturing in achieving productivity. The objectives are to identify the strengths and weaknesses of the techniques. The methodology adopted was textual analysis of existing works. It provides a radically new method of production that enables new and better designs to be realised at lower cost with enhanced productivity and greater sustainability. It also transform supply chains and the way businesses operate that will result in completely new business models. The strengths identified are part complexity; material types and low volume production – advantage and the weaknesses are large parts; high accuracy and surface finish; high-volume production; and material properties.
