Abstract:

Additively manufactured or 3d printed components are commonly used for rapid prototyping or small series production purposes. Their mechanical properties, especially in the acoustic regime, are sparsely researched as of now. Therefore, we present a non-destructive measurement procedure to characterize the properties of additively manufactured components. We manufacture 3mm thick plates by fused deposition modeling of polylactic acid (PLA). Using focused laser radiation, broadband ultrasonic Lambwaves are excited in the plates via the photoacoustic effect. These waves are detected using a purposebuilt ultrasonic transducer for plate waves. The measurement signals processed are compared to the output of a plate waveguide model. In an inverse procedure, the material parameters of the model are optimized to yield estimates for the material properties of the sample. Using this approach, we analyze the influence of printing process parameters on the mechanic and acoustic properties of the manufactured specimens.
