As part of my cooperative PhD at the University of the Bundeswehr Munich under the supervision of Prof. Josef Kiendl, and in collaboration with the FH Münster / Münster School of Architecture, I have developed a parametric workflow that automatically adapts 3D-printing geometries to different process parameters, slicers and LFAM systems.
The goal is to enable a robust CAD/CAM automation framework for 45° planar printing, independent of the specific machine configuration.
A First Demonstrator: 45°-Printed Boat Hull
To validate this workflow under real LFAM conditions, a boat hull was printed entirely with 45° inclined layers. The demonstrator illustrates how rule-based parametrisation, algorithmically generated bridge surfaces and continuous toolpaths can produce self-supporting, watertight structures without support material.
Fabrication at the FLAB, UniBw Munich
The prototype was produced on a CEAD LFAM system within the dtec.bw research project at the Forschungszentrum Leichtbau (FLAB), with support from Tobias Herrlein.
Water-tightness and functional behaviour were subsequently tested in the Hydraulics Laboratory with assistance from Dr.-Ing. Ivo Baselt.
Ongoing Research
This demonstrator forms the foundation of my PhD “Parametric Automation of Geometry and Toolpaths for LFAM”, which continues to explore adaptive geometry preparation, continuous toolpaths and advanced slicing strategies for large-format additive manufacturing.
