Abstract
An additive manufacturing machine is offered which creates a three-dimensional (3D) object by melting a powdered material with a beam such an electron beam and which shapes the surface of the 3D object at improved accuracy. The 3D object is obtained by tightly spreading the powdered material (31) on a support stage (43) and illuminating the powdered material (31) with a beam (B) to melt and bond together grains of the powdered material. The beam generated by a beam generator (11) is a pulsed beam and used to melt or sublimate the powdered material.
Claims10
An additive manufacturing machine comprising:
- a support stage on which a powdered material is spread tightly;
- a beam generator producing a beam;
- a lens for focusing the beam produced by the beam generator onto the powdered material spread on the support stage;
- and
- a controller for causing the beam generator to selectively produce a continuous beam or a pulsed beam as the beam produced by the beam generator.
An additive manufacturing machine comprising:
- a support stage on which a powdered material is spread tightly;
- an electron gun producing an electron beam;
- a lens for focusing the electron beam produced by the electron gun onto the powdered material spread on the support stage;
- and
- a controller for causing the electron gun to produce a pulsed electron beam as the electron beam produced by the electron gun.
A method of fabricating a three-dimensional multilayered object by spreading a powdered material tightly on a support stage, illuminating the powdered material with a beam, and melting and bonding together grains of the powdered material to obtain the three-dimensional object, said method comprising the step of:
- selectively producing a continuous beam or a pulsed beam as the illuminating beam.
A method of fabricating a three-dimensional multilayered object by spreading a powdered material tightly on a support stage and illuminating the powdered material with an electron beam from an electron gun to melt and cure the powdered material, said method comprising the step of:
- producing a pulsed beam as the electron beam produced by the electron gun to melt or sublimate the powdered material.
