Abstract
A method for obtaining, by additive manufacture, a component including at least one recess, this method including: a step of forming, by additive manufacture, a one-piece blank component, in which the at least one recess contains a support including a core in the form of a block of material and cellular elements that connect the core to the recess; and a step of detaching the support from the rest of the blank component in order to expose the recess.
Claims10
A method for obtaining, by additive manufacturing, a one-piece blank component including at least one recess (27), including:
- a step of forming the one-piece blank component by additive manufacturing on a build plate (T), during which:
- at least one recess comprises an upper inner portion (57) that needs to be supported, and a lower inner portion (58) opposite the upper inner portion (57), and
- a support (60) is formed in said at least one recess, the support including a core (61) provided with a hole (66) and cellular elements (S1;
- S2) including at least one lower module (S1) that connects the lower inner portion (58) to the core (61), and an upper module (S2) that connects the core (61) to the upper inner portion (57);
- a step of detaching the support (60) from the blank component in order to expose the recess (27), comprising:
- an engagement of an insertion end (69) of a tool (67) in the hole (66), then
- a rotation of the core (61) by the tool (67) inducing a rupture of the lower and upper modules (S1, S2) for the extraction of the core (61).
