Zusammenfassung:	The invention belongs to the technical field of additive manufacturing, and particularly relates to a selective laser melting TiAl-(Sn-xAl) alloy and preparation. The selective laser melting TiAl-(Sn-xAl) alloy is prepared from TiAl-based pre-alloy powder and Sn-xAl pre-alloy powder; the addition amount of the Sn-xAl pre-alloyed powder accounts for 0.2%-10% by mass of the total mass; and the mass ratio of Sn to Al in the Sn-xAl pre-alloyed powder is (80-90): (10-20). The selective laser melting TiAl-(Sn-xAl) alloy has the advantages of simple preparation process, short flow, lower equipment requirement and easiness in control of alloy components. According to the selective laser melting TiAl-(Sn-xAl) alloy, the Sn-xAl alloy is added, so that the TiAl-based alloy has excellent wettability, the defects of pores and the like of the TiAl-based alloy in the rapid solidification process can be overcome, the density of the selective laser melting TiAl-based alloy is further improved, and the obtained TiAl-(Sn-xAl) a
