Problems solved by technology

Third, the already glowing metal may have been locally damaged or at least changed in material properties
The disadvantage of this method is that the distance between the powder surface, the modulator and the decomposer needs to be very precise, which means that the system may be expensive and / or may have defined temperature intervals at which The system has the required accuracy over temperature intervals

Abstract

An apparatus for forming a three-dimensional article through successive fusion of parts of a powder bed, which parts corresponds to successive cross sections of the three-dimensional article, the apparatus comprising: a powder distributor configured for evenly distributing a layer of powder on top of a work table provided inside a vacuum chamber; and an electron beam source emanating an electron beam configured for fusing the powder layer in selected locations corresponding to the cross section of the three-dimensional article, wherein: the powder distributor being an elongated rod provided movable at a predetermined distance above the powder bed and with its central axis in parallel with a top surface of the work table, wherein at least one sensor is provided on the powder distributor facing towards the electron beam source, a detector for detecting a signal sent out from the sensor when the sensor is interacting with the electron beam.

Description

technical field [0001] The invention relates to a device for forming at least one three-dimensional object by fusing powder layer by layer. Background technique [0002] Freeform manufacturing, or additive manufacturing, is a method of forming three-dimensional objects by the continuous fusion of selected portions of layers of powder applied to a workbench. [0003] Such equipment may include: a table on which a three-dimensional object is to be formed; a powder dispenser arranged to place a thin layer of powder on the table to form a powder bed; an energy beam; elements for controlling the energy emitted by the energy beam to cover the powder bed to form cross-sections of the three-dimensional article by fusion of portions of the powder bed; and a control computer in which information is stored about successive cross-sections of the three-dimensional article. The three-dimensional article is formed by continuous fusion of cross-sections of successively formed powder layers...
