Abstract: A method for determining additive manufacturing parameters for the manufacture of an additive manufacturing support (1) for a target part exhibiting an overhang comprises the steps of: (a) additive manufacture of a plurality of supports for each supporting an overhang (2) of a test part (3), each support (1) being associated with a collection of manufacturing parameters and a collection of geometric parameters pertaining to the overhang (2); (b) manufacturing the test part (3) and observing, for each support (1), a collection of mechanical parameters pertaining to the support (1); (c) determining the additive manufacturing parameters for the manufacture of the support (1) of the target part on the basis of the geometric parameters pertaining to the overhang of the target part and of the mechanical parameters pertaining to the support.

Abstract: The present invention relates to an additive manufacturing support (1) comprising, on a plate of an additive manufacturing machine, a stack produced by additive manufacturing, having: on the one hand, a breakable zone with a structure suitable for holding, during its manufacture, a part (100) intended to be produced by additive manufacturing, and on the other hand, between the plate and the zone with a breakable structure, an intermediate zone with a porous structure.
