Deposition of melt electrowritten (MEW) fibres on clinically relevant shapes and materials. A) Schematic representation of the different collecting geometries ranging from flat (with a thickness of 1 and 4 mm) to a 45°-wedge and curved dome-shaped structures. B) Curved shape structures were designed to approach the geometry of an average human femoral condyle surface. C) Schematic representation of the MEW process, where PCL micro-fibres are patterned on a substrate with the geometry that mimics the contour of an articulating joint.
