Abstract
A method for manufacturing a three-dimensional biomedical device for fitting in a bone defect having an osteoinductive first area with a controlled porosity and a second area, which is produced by laser technology from an absorbent and from a first powder including one of ceramics, metals, metal alloys, bioactive glasses, lead zirconate titanate and biocompatible polymers, or mixtures thereof, wherein the ratio of the porosities from the second area to the first area is equal or less than one, preferably from 0.001 to 0.9, wherein a virtual object is designed with a computer-aid designed software, and the device is manufactured by laser technology including layering a powder onto a plate (7) so that a layer of a predetermined thickness is formed; the laser beam (8) selectively processes the powder to produce a processed layer, and, thus, layer after layer, the layers are joined together until the biomedical device is formed.
