1. Introduction 1. Introduction

All advances in manufacturing processes over the last 50 years have led to a rapid and continuous progress on the manufacturing industry (Lauwers et al. 2014). However, it is possible to divide these manufacturing processes in two main techniques: subtractive manufacturing (SM) and additive manufacturing (AM). The first one (SM) can be a manual process or, more recently, a Computer Numerical Control (CNC) machining process, in which sections of All dva ces in manufacturing processes over th last 50 year have led to a rapid and con inuous progres on the nufa tur ng industry (Lauwers et l. 2014).
