Notes

Abstract: This work explores the viability of 3D printed intervertebral lumbar cages based on biocompatible polycarbonate (PC-ISO®
material). Several design concepts are proposed for the generation of patient-specific intervertebral lumbar cages. The 3D printed
material achieved compressive yield strength of 55MPa under a specific combination of manufacturing parameters.The literature
recommends a reference load of 4,000N for design of intervertebral lumbar cages. Under compression testing conditions,
the proposed design concepts withstand between 7,500 and 10,000N of load before showing yielding. Although some stress
concentration regions were found during analysis, the overall viability of the proposed design concepts was validated.
