RELATIONSHIP BETWEEN RHEOLOGICAL PROPERTIES OF HYDROGELS, BIOPRINTING PARAMETERS AND 3D SCANNER TECHNOLOGY

Abstract Introduction In bioprinting techniques, tissue engineering from 3D models to generate the desired geometry is as important cell proliferation, it will be key survival of printed and its functional success. Methods Alginate-based hydrogels were used because they are most widely by scientific community for bioprinting. The alginate-based characterised using a rheometer obtain boundary conditions applied in computational software. A 2D axisymmetric model together with two-phase flow level set interface nozzle human tooth carried out verify results obtained. Results data showed that droplet detachment occurs at lower pressures based on higher percentage alginate. addition, samples alginate less sensitive pressure during extrusion. Conclusions
