Abstract
The implant (1) includes at least two assembled components, at least a first component (3) is intended to be movable relative to at least a second component (2). The method includes the steps of: designing the implant (1) such that the second component (2) at least partially envelops the first component (3) and that at least one connecting bridge (4) connects the first component to the second component, each bridge (4) having a section such that it is frangible; making the implant (1) using a so-called “3D printing” method, includes depositing on a platen, a layer of powdered fusible material, causing the particles of this layer of powder to fuse in locations corresponding to the shape which, at this layer, the first component (3, 23, 33, 53, 63) and/or the second component (2, 22, 32, 52, 62) and/or the at least one bridge (4, 24, 54, 64) have, depending on whether the first component, the second component and/or said bridge are present at the section the implant to be formed has at the layer; repeating these operations until the implant (1, 21, 31, 51, 61) is fully constructed, and eliminating the powder particles that are not fused.
