1. A method for: obtaining, by additive manufacturing, a component including at least one surface that has to be supported during manufacture, including:
a step of forming by additive manufacturing a one-piece blank component on a build plate comprising a support including:
a pillar comprising a foot from which the manufacture of this pillar starts,
wherein the foot is perpendicular to the plate,
the pillar being a block of material, and
wherein the pillar further comprises,
an inclined segment defining an acute angle with the build plate,
a head formed at a distal end of the inclined segment, wherein said head widens to form a support base corresponding along a longitudinal axis to the at least one surface to be supported, and
a cap formed on the support base, said cap comprising a cellular element connecting the pillar to the surface to be supported;
a step of detaching the support from the rest of the blank component comprising pulling on the foot in the manner of a lever by following an arc path.
