Beschreibung
Zusammenfassung:	An additive manufacturing method, comprising the following steps: on the basis of a shape of a model of a printing member (P2), generating a model of a support member(S2); continuously introducing an inert gas into an additive manufacturing printing device, spreading a first material powder in a forming cylinder (150) in the additive manufacturing printing device, performing laser scanning on the first material powder, such that the first material powder is melt, and on the basis of the model of the printing member (P2),the printing member (P2) and the support member (S2) below a portion of the printing member (P2) are formed layer by layer; and introducing an ammonia gas into the additive manufacturing printing device, spreading the first material powder in the forming cylinder (150) in the additive manufacturing printing device, performing laser scanning on the first material powder, such that the first material powder is melt, and on the basis of the model of the support member (S2), a nitride layer (200) is formed on an upper surface of the support member (S2). The present invention provides a support member that is easy to be removed, guarantees printing quality, and has a low cost.
