Synchronously Enhanced strength-ductility of L-DEDed GH4169 with Varying Energy Input

•A synchronously enhanced strength-ductility of L-DEDed GH4169 was achieved by increasing the laser energy input.•The mechanism underlying the strength-ductility enhancement is revealed to be the texture variation.•The deformation-induced twinning was discovered in L-DEDed GH4169 with high energy input.
