| Abstract Scope |
In the pursuit of fabricating polymer textile scaffolds for regenerative medicine, several fiber deposition techniques have been studied. However, a single forming technique may be insufficient to meet the mechanical and biological requirements for a tissue engineering device. The fabrication of geometries that better conform to the anatomy of the target tissue is often neglected due to the inability of current techniques to fabricate non-planar textiles. In this work we present the integration of Melt Electrowriting and Fused Deposition Modeling to deposit textiles on curving surfaces and to incorporate cell-bearing hydrogel sheets that are strong enough to support suturing, have a balanced microstructure in fiber and pore size that is suitable for cell proliferation and vascularization, and which feature personalized out-of-plane, form-fitting geometries produced by using multi-axis kinematics. This “hybridization” of techniques in a single printer is currently being applied for the fabrication of personalized bone and corneal implants. |
