    <title language="eng">Design Rules for Hybrid Additive Manufacturing Combining Selective Laser Melting and Micromilling</title>
    <abstract language="eng">We report on a comprehensive study to evaluate fundamental properties of a hybrid&#13;
manufacturing approach, combining selective laser melting and high speed milling, and to characterize&#13;
typical geometrical features and conclude on a catalogue of design rules. As for any additive&#13;
manufacturing approach, the understanding of the machine properties and the process behaviour as&#13;
well as such a selection guide is of upmost importance to foster the implementation of new machining&#13;
concepts and support design engineers. Geometrical accuracy between digitally designed and&#13;
physically realized parts made of maraging steel and dimensional limits are analyzed by stripe line&#13;
projection. In particular, we identify design rules for numerous basic geometric elements like walls,&#13;
cylinders, angles, inclinations, overhangs, notches, inner and outer radii of spheres, chamfers in build&#13;
direction, and holes of different shape, respectively, as being manufactured by the hybrid approach&#13;
and compare them to sole selective laser melting. While the cutting tool defines the manufacturability&#13;
of, e.g., edges and corners, the milling itself improves the surface roughness to Ra &lt; 2 µm. Thus,&#13;
the given advantages of this hybrid process, e.g., space-resolved and custom-designed roughness&#13;
and the superior geometrical accuracy are evaluated. Finally, we exemplify the potential of this&#13;
particular promising hybrid approach by demonstrating an injection mold with a conformal cooling&#13;
for a charge socket for an electro mobile</abstract>
