Robocasting and surface functionalization with highly bioactive glass of ZrO₂ scaffolds for load bearing applications

This work is a proof of concept for making load bearing implants with osseointegration and bone bonding ability. Yttria‐stabilized zirconia (YSZ) scaffolds with a percentage of macro porosity of about 70% were fabricated by robocasting. Although a maximum solids volume fraction of 50 vol.% could be achieved, the 3D‐printing process revealed to be more reliable when using inks with 48 vol.% solids. The sintered porous structures exhibited an...
