New Publication Released from the University of Stuttgart


TresClean partner, the University of Stuttgart, have published a paper in the Applied Physics A journal. Titled "Prediction of the surface structures resulting from heat accumulation during processing with picosecond laser pulses at the average power of 420 W". Within this study, a novel heat accumulation model is introduced to calculate the temperature increase in the workpiece for the whole process including the effects of HAP and HAS in which the latter is differentiated between heat accumulation due to multiple passes (HAS-I) and heat accumulation due to multiple layers (HAS-II). With the new model, the surface structure was successfully predicted when using an ultra-short pulsed (USP) laser with an average power of 420 W for laser surface structuring of polished AISI 316L.
