This work aims on the additive manufacturing of new functionalized multi-material dental brackets (met-al/polymer) for braces. Stainless Steel (≤ 0.1 at.-% Ni) powder has been selected for the main body as it is free from allergic response. The polymer coating has to suffice aesthetic and microbiological requirements. The inter-face between metal and polymer is based on mechanical interlocking by microstructures, thus, the optimization of surface micro topographies on the printed brackets is a key factor. The following study is divided in the opti-mization of process parameters for bulk parts, as well as surface micro topographies. The physical characteriza-tion of parts will be carried out by means of density and surface roughness analyses, and the mechanical prop-erties by means of tensile tests and hardness measurements. The investigation of micro topography features, such pins and pockets, will be carried out by optical and confocal microscopy. To evaluate the mechanical interlocking of the pins, polymer injection molding process was performed on the metal brackets, followed by performance assessment, through tensile test. The pull of strength was evaluated by means of pin geometry, size and density.
