This method for producing a three-dimensional object (1) from a powder or from a mixture of powders by sintering and/or laser melting comprises manufacturing steps consisting of depositing, compacting, then solidifying, in predetermined areas, successive layers of the powder or of the mixture of powders. It further comprises the following steps: a) before implementing the steps of manufacturing the three-dimensional object and from a manufacturing table (3), manufacturing, by sintering and/or laser melting, a support (5) whereof the surface or surfaces oriented towards the three-dimensional object to be manufactured are respectively homothetic to surfaces (11) opposite the three-dimensional object to be manufactured; b) manufacturing, by sintering and/or laser melting, blades (7) for supporting the three-dimensional object to be manufactured on the support produced in step a); c) manufacturing the three-dimensional object from the upper surfaces of the blades manufactured in step b) and d) when the manufacturing of the three-dimensional object is complete, detaching the three-dimensional object from the support by applying a force to the three-dimensional object or to the support, moving the object and the support relative to one another until the blades break. |
