To address these challenges, a novel approach integrating additive and subtractive laser processes at the layer level has been developed. This quasi-simultaneous manufacturing process enables the fabrication of small structures with high aspect ratios, including narrow slits below 50 μm in width. The implications of this advancement are promising, particularly in the fields of electric drives and fuel cells, where accuracy and freedom of design are crucial. In this work, the latest results of the production of narrow, inclined slits in components made of pure iron will be shown. Characteristics like groove-to-groove distance and groove width were analyzed, achieving successful production of continuous slits with varying inclination angles of up to 30° within the manufactured components.https://puma.ub.uni-stuttgart.de/bibtex/208fa8354a72c899275b2bf667cd24bfe/ifswifsw2024-05-14T16:33:35+02:00myown ablation additivemanufacturing micromaterialprocessing ultrashort selectivelasermeltingslm macromaterialprocessing pulse processdevelopment <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Manuel Henn" itemprop="url" href="/person/1420dbfc085d8ab2f791c55ca474c62eb/author/0"><span itemprop="name">M.
