Poly (ε-caprolactone) (PCL) is a biodegradable polyester commonly used in biomedical devices. This work involved the fabrication of micron-scale fibers and scaffolds using solvent-cast 3D printing with polymer inks comprised of PCL in Hexafluoro-2-propanol (HFIP) solvent. The purpose of this study was to measure the mechanical properties of solvent-cast fibers for comparison to bulk PCL and to assess the feasibility of using controlled fiber deposition to tune the resultant structural mechanical properties of solvent-cast scaffolds. A range of needle gauges were used to print fiber arrays for mechanical testing and a series of parameterized scaffold architectural variants were subsequently explored. The results showed that solvent-cast fibers have comparable mechanical properties to PCL in its bulk form. Additionally, the uniaxial stiffness of high-aspect-ratio scaffolds was shown to vary by more than an order of magnitude, just with changes in orientation of a geometric unit cell with respect to the axis of loading. For high-aspect-ratio scaffolds in which continuous fibers were oriented parallel to the axis of loading, the scaffolds were twice as stiff than an equal number of disconnected parallel fibers, due to the structural reinforcement conferred at the joints between scaffold layers. Overall, this work suggests that solvent-cast 3D printing may be useful for fabrication of highly controllable structures with widely tunable mechanical properties.
