Abstract (en)
[origin: WO2022171234A1] The invention relates to a method for cleaning powder residues of an additive layer build-up method away from an at least partly additively manufactured component (3) by means of a cleaning device (1), wherein a machine plate (2) and the component (3) arranged thereon are excited to mechanical oscillation during a cleaning process by a vibration actuator (4) of the cleaning device (1) with a set resonant frequency of the machine plate. According to the invention, before the cleaning process is carried out, a resonant frequency of the machine plate (2) is set to the set resonant frequency by an arrangement of a mass element (6) on a securing element of the machine plate (2), wherein the set resonant frequency is ascertained according to a predetermined selection method depending on at least one resonant frequency of the component (3), and the margin separating the set resonant frequency of the machine plate (2) from the at least one resonant frequency of the component (3) is greater than that separating the resonant frequency of the machine plate (2) without the arranged mass element (6), and at least one parameter of the mass element (6) is ascertained according to a predetermined ascertaining method depending on the set resonant frequency of the machine plate (2). The invention furthermore relates to a cleaning device (1) for cleaning an at least partly additively manufactured component (3).
