Abstract
An additive manufacturing method and machine for an object using at least one powder, capable of limiting risks of dissemination of the powder. The method including the following steps in succession: manufacture a solid block starting from the powder and a sublimatable material, load the solid block in a loading space of the machine; sublimate the material present in the solid block and recover the powder; and additive manufacturing of the object by stacking successive layers made using the powder recovered in the previous step.
