Porous calcium phosphate (CaP) scaffolds have been used in medicine for bone regeneration in a case of a bone tissue loss for decades [, ]. Owing to specific shapes of voids there is a need for implants’ individualization. We investigate a possibility of employing CAD/CAM technology and a multi axis milling of porous ceramics in the field of a preparation of individualized bioceramic scaffolds. Hydroxyapatite foams with a proper structure were prepared by combination of a direct foaming method and an epoxy gel-casting []. Rheology of suspensions as well as mechanical and structure characterizations of HA foams were described. A machinability of HA foams in a different stage of a heat treatment were evaluated both qualitatively using a uniform milling pattern and quantitatively correlating the mechanical characteristics to machining results. Improvement of the machinability by temporary saturation of the structure by a paraffin wax was investigated as well. Practical usage of the multi axis milling has been demonstrated at the example of mandibular defect
