More Information
Summary:The disclosed invention discloses the use of a sensor read out system with at least one fiber optical sensor (50), which is connected via at least one signal line (51) to a processing unit (52) as part of an additive manufacturing setup, for in situ and real time quality control of a running additive manufacturing process, wherein acoustic emission is measured via the at least one fiber optical sensor (50) in form of fibers with Bragg grating, fibre interferometer or Fabry-Perot structure (500), followed by a signal transfer (51) and an analysis of the measured signals in the processing unit (52), estimation of the sintering or melting process quality due to correlation between sintering or melting quality and measured acoustic emission signals and subsequent adaption of ion and electron beams, microwave or laser sintering or melting parameters of a ion and electron beams, microwave or laser electronics (1) of the additive manufacturing setup in real times via a feedback loop (53) as a result of the measured acoustic emission signals after interpretation with an algorithmic framework in the processing unit (52).
