“…In the literature, a substantial work on AM of aluminium alloys with PBF-Laser technique shows that all types of aluminium alloys are printable using this particular process [16]. In contrast, recent studies on WAAM show that only specific 2XXX [17][18][19][20][21][22][23][24][25], 4XXX [26][27][28][29][30] and 5XXX [20,22,27,28,[30][31][32][33][34][35][36] series can be successfully deposited. Thus, an upstream development is absolutely required to obtain WAAM-built parts using 6XXX and 7XXX series of aluminium alloys [37,38].…”
