© 2019 Elsevier Ltd. All rights reserved.This study focuses mainly on the development and design of hydrogels of polyvinyl alcohol and gelatin. The Ag, TiO2, Na2Ti6O13 (sodium hexatitanate) and tricalcium phosphate (Ca3(PO4)2) reinforcement particles possess very interesting characteristics, such as bioactivity and antibacterial properties. Several studies were performed: mechanical properties, swelling, scanning electron microscope (SEM) and the validation of extrusion in a 3D printing machine. SEM images show a high porosity in all samples, especially in the sample with TiO2 (300 micron). Samples with titanium dioxide and silver reinforcement display a strength above 100 MPa. Further, in vitro analyses are been developing in order to confirm viability assays.
