W pracy omówiono strukturę kompozytów bioresorbowalnych wytworzonych z wykorzystaniem technologii laserowych. Metoda polega na selektywnym topieniu mieszaniny sferoidalnych proszków polimeru i ceramiki, warstwa po warstwie, co w efekcie pozwala uzyskać lity element o zamodelowanym kształcie, gotowy do wszczepienia pacjentowi.

Process of producing implants with laser technology allows to individually adjust them to the patient as well as to the level of damage to his bones. One of the important features of the process, which can be manipulated, it is possible to precisely determine the structure of the implant, having the same effect on its porosity. In the case of bioresorbable implants it is a key issue in the context of determining the time the implant is absorbed by the body. Giving properly function to the implant and meet all of its functions, its porosity must be modeled in a way that the subsequent penetration of the blood and cells in the channels. Previous types of implants could be penetrated by the patient's cells to a limited extent. The new technique can generate channels with a diameter of 0.5 to 1 mm with an accuracy of 100 microns. This method allows the production of parts with complex shapes (eg based on CT images) in one operation. A limited number of operations, the material used and the specifics of the process gives a chance to respond quickly to the needs of individual patients, and this influences progress in the development of implantology.
