Zusammenfassung:The invention relates to a process for manufacturing a glass-fiber-reinforced composite used for manufacturing customized implants by using the 3D printing technique. According to the invention, the process consists in mixing an organic matrix made of methacrylic monomers with nano-filling of hydroxyapatite, zirconium oxide and gentamicin, at the room temperature, for 2 h, resulting in a resin which impregnates a glass fiber cloth, wherefrom, after the lamination process, a composite reinforced with glass fiber is obtained which is thermally treated inside an electric oven at 100°C, further on the residual monomer is removed by extraction with solvent, to result in a biomaterial having antimicrobial effects and favourable biological reactions. Invenţia se referă la un procedeu de obţinere a unui compozit ranforsat cu fibră de sticlă utilizat pentru realizarea de implanturi personalizate prin tehnica de imprimare 3D. Procedeul, conform invenţiei constă în amestecarea unei matricei organice constituită din monomeri metacrilici cu nanoumplutură de hidroxiapatită, oxid de zirconiu şi gentamicină, la temperatura camerei, timp de 2 h, rezultând o răşină care impregnează o ţesătură de fibră de sticlă prin procesul de laminare rezultând un compozit ranforsat cu fibră de sticlă care este tratat termic într-un cuptor electric la 100°C, în continuare se îndepărtează monomerul rezidual prin extracţie cu solvent, rezultând un biomaterial având efecte antimicrobiene şi de reacţii biologice favorabile.
