The fast fabrication of customized ceramic parts for biomedical applications is one of the today challenge. This work proposes to combine two rapid manufacturing techniques: the micro-stereolithography (SLA) allowing a rapid shaping of complex ceramic parts and the microwave thermal treatment allowing the debinding and the sintering within a very short time. This technology was applied to two bioceramics types: alumina, zirconia and composites materials for dental crowns or implants and hydroxyapatite for scaffolds. For these porous parts, the interest to use the stereolithography technique is an easy achievement of porous objects with a control of pores and pore interconnection sizes and shape to favor the cell invasion. For all the investigated materials, it was shown the coupling SLA and MW sintering leads to similar mechanical properties than those obtained by conventional shaping and sintering and that it allows to obtain customized parts within a few hours.
