This work identifies and describes different material-scaffold geometry combinations for Cartilage Tissue Engineering (CTE). Previously reported potentially interesting scaffold geometries were tuned and printed using bioresorbable PCL (polycaprolactone) and PLA PEG- (poly(lactide-b-ethylene) block copolymer).

Medical grades of both polymers were 3D printed with FFF technology within an ISO 7 classified cleanroom. Resulting scaffolds were then optically, mechanically and biologically tested.

Results indicated that a few material-scaffold geometry combinations present potential for excellent cell viability as well as for an enhance of the chondrogenic properties of the cells, hence suggesting their suitability for CTE applications.
