Zusammenfassung:	Method for preparing the upper surface of a build platform for additive manufacturing by powder bed deposition, the method comprises at least one step of increasing the roughness of at least one region of the upper surface of the build platform by imprinting a pattern onto this region. The imprinting of the pattern is done inside the machine for additive manufacturing by powder bed deposition in which the build platform is subsequently used for additive manufacturing by powder bed deposition.
