This Project starts from an existing technology for synthesis of personalized cranial prostheses developed in collaboration between the Laser-Surface-Plasma Interactions Laboratory in INFLPR and Dr. Oblu Hospital in Iasi and it aims towards a radical modification of the method for easier implementation, an increase in prostheses shape and dimensions flexibility and a drastic reduction of production costs. The initial procedure started with acquisition of commercial metallic prostheses shaped in form of a mesh (1), their coating with a thin film of bioactive ceramic by pulsed laser deposition (2), identification of fractures dimensions by computer tomography (3), manual cutting of the meshes function of the wound dimensions (4). The new method involves a single step direct synthesis by laser additive manufacturing of a prosthesis with required dimensions covered by a bioactive layer, starting from metallic and ceramic powders. The aim is to eliminate the steps that involve acquisition of expensive commercial devices and the deposition techniques that require high vacuum and heating of the prostheses at high temperatures. We aim at the end of the Project to delineate the technology that will allow a single user to scan a patient by computer tomography, the fracture’s dimensions to be introduced in a pre-established CAD-CAM software and with the push of a single button to be able to generate in real time a prosthesis with required dimensions and functionality.
The coordinators of the involved teams, Dr. Andrei Popescu, project leader (INFLPR) and Dr. George Stan, project partner (INFM) have a long experience in deposition of biocompatible coatings by PLD and MS, being pioneers in study of bioactive glass coatings synthesized with these techniques in Romania.
​
Both involved Laboratories are already included in the official tour for visits of students, high school classes and general public during ‘open days’ events. This research will be also highlighted during these visits and explained to the general public.

Project development
Because the subject is new and the perspective of innovative results is high, the team plans to patent at national level any innovative methods developed during this project. The valuable scientific data useful for the scientific community will be presented in form of two manuscripts to be published in ISI Journals with impact factor >2. Moreover, the authors will present the results in oral and invited presentations at International Conferences.
