Project: Additive Manufacturing of Magnesium-based Biodegradable Implants with Controlled Corrosion Rate and Infection

Acronym AM-MBI (Reference Number: MNET20/ADDI-3741)
Duration 01/01/2021 - 01/01/2023
Project Topic The project objective is to obtain advanced orthopaedic and maxillofacial biodegradable implants with high biological and mechanical compatibility, from a new Mg alloy, using 3D Printing Near Net Shape technology. For medical performance, the new implants will have controlled degradation rate, osteoconductive and antibacterial functionalized surface. The project consortium gathers multidisciplinary scientific teams from Romania and Navarre (R&TD units and SMEs). The work plan consists of: design the new biodegradable Mg alloy composition; design of Mechanical Alloying technology to obtain Mg powder alloy; design and development of the 3D Printing/Additive Manufacturing (AM) technology to obtain the new Mg-based implants by Selective Laser Melting technique; design and experimental development of the surface multibiofunctionalization of the new AM / Mg-based implants, selected from 3 parallel investigated methods: Sol-Gel, Electrospinning, and a combination of Physical Methods (Thermal Oxidation, HVOF and PVD), each with customized composition. The project plan provides the integration of the developed technologies in a fabrication chain, obtaining a demonstrator product.
