The scientists want to use machine learning methods to process the information. The researchers' goal is to develop a process control system that adjusts the laser power as a function of transmission so that a uniform weld seam is produced вЂ“ even if the 3D-printed compo-nent does not transmit the laser beam uniformly. If the component is more light-transmissive at another point, lower laser power is sufficient. If the laser beam is less transmitted at a certain point, the laser power must be increased. This data will then be used to control the laser transmission welding process with the help of the expert system. This involves determin-ing for an individual component at which points the laser beam is transmitted and to what extent. In addition, the scientists want to develop a method to measure the transmission with spatial resolution. Using AI to adapt the process to the component Thanks to this preliminary work, it will be possible to weld the printed components optimally afterward. (Image: Laser Zentrum Hannover)Д®ven before the 3D printing process starts, the expert system is supposed to provide recommendations on which material, which layer thickness, and which layer orientation are best suited to achieve the highest possible transmission вЂ“ in other words, the highest possible permeability for the laser beam. light transmission, varies depending on the layer thickness and layer orientation. In this additive process, thin strands of molten plastic are superimposed layer by layer.ДЈD-printed sample component: The so-called transmissivity, i.e.

In the project 'Quality assurance in laser welding of additively manufactured thermoplastic components (QualLa)', the researchers are looking at fused deposition modeling (FDM) for this purpose. To enable small and medium-sized enterprises (SMEs) to weld 3D-printed plastic components with lasers without analyzing each component in detail in advance, the IPH and LZH scientists want to develop an expert system and bundle process knowledge in this computer program.

Even components from the same series are only identical on the outside the internal structure can be different.Д®xpert system replaces time-consuming analysis These cavities and boundary layers are individual to each component because, in additive manufacturing, no two components are alike. For components from the 3D printer, however, the joining does not yet work because cavities and boundary layers in the 3D-printed components prevent a uniform weld.
