(57) A machine (1) for making three-dimensional objects from powdered materials comprises a main body (3) comprising a growing cavity (5) in which a growing platform (7) for growing the object to be produced is slidably inserted. Moreover, the machine comprises depositing means (11) operatively associated with the growing cavity (5) for depositing a succession of layers of powdered materials on the growing platform (7) and an electromagnetic radiation device (18) designed for focusing a beam of electromagnetic radiation on predetermined zones of each layer of powder deposited. The machine also comprises an annular base body (19) which can be operatively associated with the growing cavity (5) of the main body (3) for forming a narrowing of the growing cavity (5). The growing platform (7) is interchangeable for adapting to the narrowing of the growing cavity (5).
