Pressure-Assisted Coating of Ceramics on 3D-Printed Polymeric Scaffolds

ACS Applied Bio Materials 2021 Volume 4, Issue 8, Pages 6462-6472

Pressure-assisted coating (PAC) is introduced to coat 3D-printed polymeric scaffolds with β-tricalcium phosphate (β-TCP) for tissue engineering applications. The method consists of four steps: infiltration of ceramic particles into the porous structure of the polymeric scaffold, dehydration of the slurry, compaction of ceramic particles around the scaffold, and heat treatment. The optimal coating is obtained at an infiltration speed of 400 mm/min followed by complete dehydration, compaction under ca. 8 MPa pressure, and subsequent heat treatment at 65 °C. The outcome is a uniformly coated scaffold with no deformation or structural defects, as confirmed by micro-CT analysis and laser and…
