Abstract
This paper presents an overview of the research work carried out for the rapid manufacture of hydroxyapatite (HA) based components by means of Selective Laser Sintering (SLS) technique, to be used for bone tissue implantation aiming to replace and/or repair bone defects due to traumatised, damaged or lost bone. SLS is a Rapid Prototyping Technology (RPT) that selectively sinters powders of engineering materials by means of a CO 2 laser. HA is a bioceramic used since several years for medical applications although being mainly processed by conventional methods (cast, machined or manually produced). For this purpose CAD/CAM, RPT and medical imaging techniques were integrated and this enabled the customised production of anatomical models. This approach provides a direct method of producing HA-based prostheses.
