Abstract (en)

[origin: WO2019091801A1] The invention relates to a processing machine (1) for producing three-dimensional components (2) layer by layer by irradiating powder (3) by means of a processing beam (6), in particular by means of a laser beam, comprising: a container (10) with a lowerable support (12) for applying the powder (3), and also an irradiating device (4) with a scanner device (8) for aligning the processing beam (6) with a processing area (B) at an opening (10a) of the container (10) for producing the three-dimensional component (2) layer by layer by irradiating the powder (3). The irradiating device (4) has a heating device (18), which has a heating radiation source (19) for producing a heating beam (20) for heating the powder (3) from above by aligning the heating beam (20) with the processing area (B) and also a beam-shaping optical unit (22), which is designed to transform a first beam profile (S1) of the heating beam (20) into a second, in particular annular, beam profile (S2) of the heating beam (20). The invention also relates to a method for heating a powder (3) in such a processing machine (1).
