Definition of cell culture materials and seeded cell number per cm². TCP as established bone replacement was used to evaluate material-depended cell reactions. Powder printing of TCP guaranteed a comprehensibility with respect to manufacturing method. For monocyte/osteoclast cell culture PS and glass was used as established cell culture control.
