In this study, a pulsed nanosecond laser was used to create patterned surfaces of stainless steel coupons to study the effect of patterning on fluid retention and biocompatibility studies of laser patterned and control surfaces.
In this study, a numerical study was performed to study the multi-physical fluid processes of laser cutting. Towards this, modeling was performed using 1.2 mm thick austenitic stainless-steel coupons that was cut using a continuous width neodymium-doped yttrium aluminum garnet (CW Nd: YAG) laser.
Extended Abstract: Three dimensional (3D) metallic porous structures are in great demand for various applications such as thermal management, filtration, lightweight structures, electrodes, and biomedical systems. Complex microporous structures are required for these desired functionalities. However, current manufacturing technologies, ie, sintering, 3D printing, etc., have a few technical barriers that prevent them from being advantageous in developing 3D porous structures.
In this work, numerical study was performed to study the multi-physical process of laser cutting. Towards this, 1.2 mm thick austenitic stainless-steel was cut using a continuous width neodymium-doped yttrium aluminum garnet (CW Nd: YAG) laser and the process was verified with published experimental results.
