Nerve conduits are tubular scaffolds which are needed for axons to regenerate across the defect to facilitate the nerve regeneration. The last decade has witnessed a number of different fabrication method which were being used for the nerve conduit fabrication. 3D printing has emerged as an up-and-coming technology to fabricate the nerve conduits of different architecture with precise replication of original nerve features. 3D printing has the advantage of precise control of dimensions at the micron level and eases to fabricate the designed structure. In this study, we have fabricated 3D printed polylactic acid (PLA) Nerve conduits for the functional recovery after the traumatic injury. Compressive testing was performed on Instron 5582 to measure the compressive strength and compressive modulus of the nerve conduits. SEM images were used for evaluating the surface morphology of the 3D printed nerve conduits. The water contact angle was used to measure the surface wettability of the nerve conduit surface. FTIR was performed to study the surface chemistry of the fabricated nerve conduits. The fabricated 3D printed Nerve conduits were also treated by UV Irradiation for the surface functionalization.
