“…Nicoletto et al [12] studied the influence of roughness and morphology on the fatigue life of Ti alloy components produced with different orientations, using either a laser or an EBM system. Thus, the finishing of the AM parts is an important issue; different techniques can be adopted, such as abrasive fluidized bed [2], laser treatment [13][14][15][16], and chemical polishing [17][18][19]. Laser treatments offer some advantages compared to the other aforementioned techniques, such as absence of any mechanical contact due to the lack of tools which lead to a no wear high accuracy and high repeatability.…”

“…in aerospace). In addition, there are application driven aesthetic and functional requirements for surfaces: for example, a smooth surface with roughness Ra < 1.0 µm is often required in dental implants to prevent bacteria accumulation [7], as illustrated in Figure 1 Typically, a high microscopic roughness of Ra > 15 µm is obtained on AM parts produced by SLM, LMD and EBM [7][8][9][10][11], but a roughness level of Ra < 0.8 µm is needed in many applications to avoid premature fatigue failure induced by surface stress concentrations [12].…”

“…More recent studies of laser polishing of additive manufactured surfaces have also shown positive results. For example, Marimuthu et al [20] have obtained a roughness reduction of 76% on SLM Ti6Al4V surfaces and Gora et al [9] achieved an 85% reduction with EBM Ti6Al4V components. Ma et al [26] used a nanosecond pulse laser and successfully reduced the surface roughness by about 80% on two types of titanium alloy AM components.…”

“…Mechanical polishing processes include grinding and honing where surface roughness in the µm range is achieved. Willenborg [10,11], Gora [12] and Bordatchev [13] described the laser polishing process in detail. In this process, a thin surface layer is melted.…”
