Structure and Validation of a Kinematic Surface Simulation Model for the Direct Laser Writing Process

Abstract

The article introduces to the structure and validation of a Kinematic–Surface–Simulation–Model for the replication of laser‐structured surfaces and their impressions after hot embossing. The surface replication is accomplished by the stepwise Boolean intersection of a structured and digitised point‐ablation with the workpiece. The resulting surface is characterised according to ISO 25178. Resulting from the Kinematic–Simulation‐Principle, the model can be applied to a wide range of material–machine combinations in the field of laser‐structuring and enables a time–efficient, nanometre‐resolved replication of representative surfaces with a size up to several square millimetres. Within the validation process it was proven, that the main surface characteristics can be predicted by the model. Compared to AI‐approaches and numerical or multi‐physical simulations, preliminary studies are only needed to a very small extent. Furthermore, complex influences such as material and temperature related properties do not need separate consideration as they are taken into account by the digitised point‐ablation.This article is protected by copyright.
