A machine for making three-dimensional objects from powdered materials, comprising: a main body forming a working surface; a growing cavity made in the main body and open at the working surface; said machine comprising a growing platform for growing the object to be produced, slidably inserted in the growing cavity and movable at least away from the working surface; feeding means for feeding the powdered materials operatively associated with the working surface for feeding said powdered materials to the working surface; an applicator unit movable along the working surface in a forward direction in which it is in a lowered position on the working surface according to a direction going away from the working surface for bringing the powdered materials from the feeding means to the growing cavity; an electromagnetic radiation device designed for focusing a beam of electromagnetic radiation on predetermined zones of each layer of powdered materials deposited on the growing platform until joining together of the granules of powdered materials is achieved; means for spacing the applicator unit acting on it for bringing it into a raised position relative to the working surface and spaced from the lowered position according to the direction going away from the working surface; said applicator unit being positioned in the raised position during a return direction of the applicator unit which is opposite to the forward direction; characterised in that the spacing means comprise a supporting unit at least partly movable relative to the working surface and extending transversely to the working surface between a relative first end and a relative second end which is opposite to the first and closer to the working surface than the first end; said applicator unit being connected to the supporting unit at the second end; said spacing means comprising locking means acting on the supporting unit for locking it between a raised position in which the applicator unit is spaced from the working surface and a lowered position in which the applicator unit is in contact with or positioned at a first distance from the working surface. a main body forming a working surface; a growing cavity made in the main body and open at the working surface; said machine comprising a growing platform for growing the object to be produced, slidably inserted in the growing cavity and movable at least away from the working surface; feeding means for feeding the powdered materials operatively associated with the working surface for feeding said powdered materials to the working surface; an applicator unit movable along the working surface in a forward direction in which it is in a lowered position on the working surface according to a direction going away from the working surface for bringing the powdered materials from the feeding means to the growing cavity; an electromagnetic radiation device designed for focusing a beam of electromagnetic radiation on predetermined zones of each layer of powdered materials deposited on the growing platform until joining together of the granules of powdered materials is achieved; means for spacing the applicator unit acting on it for bringing it into a raised position relative to the working surface and spaced from the lowered position according to the direction going away from the working surface; said applicator unit being positioned in the raised position during a return direction of the applicator unit which is opposite to the forward direction;
