Abstract
A machine for additive manufacturing comprises a work top, a work area, a device for depositing a layer of powder onto the work area and a heat or energy source used to selectively consolidate a layer of powder, the device comprising a movable element for receiving powder moving relative to the work top and in the vicinity of the work area, a device for dispensing a bead of powder onto the movable element and a device for spreading the bead of powder. The movable element assuming the form of a translationally movable slide or the movable element rotationally moving around the work area, at least part of the upper surface of a movable element is located above the upper surface of the work top and/or at least part of the upper surface of a movable element is located below the upper surface of the work top.
