| Abstract Scope |
Each year in the US 6.5 million bone defects arise from trauma, tumors, infections, and congenital conditions, often requiring external intervention. Fused Deposition Modeling (FDM) provides a cost-effective and accessible method for producing bone-mimicking scaffolds that offer temporary support and facilitate natural bone healing. Such an FDM-generated scaffold can also address the global demands for accessible bone regeneration solutions in an orthopedic office. In return, it demands accessible design and affordable stable filament solutions, which are currently commercially unavailable. This work focuses on the design, analysis, and manufacturing of a trabecular bone-mimicking CAD structure, with a particular emphasis on the solution's affordability and accessibility in a physician's office. The material of choice for this analysis was commercially available polylactic acid (PLA) and an in-house-generated filament using Polycaprolactone (PCL) and hydroxyapatite (HA) composites in varying ratios. These materials were selected for their FDA approval across different orthopedic and biomedical applications. |
