Processing of ceramic or glass ceramic parts by using solid free forming systems facilitates the fabrication of customized geometries (e.g. implants or scaffolds) for bone tissue engineering (scaffolds). However, the fixation of such customized ceramic implant on bone may not be doable by conventional methods like screwing due to geometrical limitations and tendency towards brittle fracture of ceramic parts. This thesis presents the feasibility to process a bioactive glass by lithography-based additive manufacturing technique (AMT), and the fixation of manufactured parts with a biocompatible light curing adhesive. Processing of ceramics by lithography-based AMT was applied to fabricate Bioglass® 45S5 parts for the first time in this research, which allowed the design and fabrication of customized cellular structures for orthopedic implants or scaffolds for bone tissue engineering from Bioglass® 45S5. The parts were fabricated with 25 µm in layer thickness (z-direction) and 40 µm resolution in the x-y plane.
