Embodiment Construction

[0033] The purpose of the present invention is to introduce a novel method for quality control of additive manufacturing (AM) processes, in particular based on ion beam, microwave or laser powder sintering or melting (for powder bed and ion and electron beam, microwave or laser powder deposition). The method is intended to be an independent feedback control loop, providing real-time online monitoring of the additive manufacturing process. Furthermore, an apparatus using the method is disclosed.

[0034] Additive manufacturing device including ion and electron beam, microwave or laser irradiation system, ion and electron beam, microwave or laser irradiation system including ion and electron beam, microwave or laser electronic device 1 controlled ion and electron beam, microwave or laser source 2 , ion and electron beam, microwave or laser focusing device 3, ion and electron beam, microwave or laser focusing device 3 irradiates ion and electron beam, microwave or laser source 2...
