Three-dimensional (3D) printable scaffolds are advantageous for their ability to be custom made to fill hard tissue defects. In this approach, scaffolds are required to be osteoconductive such that cells (osteoblasts) can attach and proliferate on the scaffolds and subsequently go on to become bone. It is desirable for the scaffold to biodegrade while bone formation occurs. Biodegradation occurs through the process of polymer chains being broken down into smaller chains, resulting in eventual extinction of the polymer altogether. Knowledge of biodegradation rates is important for prediction of scaffold stiffness and strength used in engineering analysis. Polylactic acid, or PLA, is a popular filament used in 3D printing (3DP). Biodegradation of PLA occurs through the process of hydrolysis which utilizes water molecules to break down the polymer chain. In this study, PLA scaffolds were tested to determine their baseline degradation rates. Eight X-type scaffold specimens were selected for the assessment of PLA sustainability due to soaking in cell culture media held at room temperature (20° C). Specimens were weighted, measured, and mechanically tested at the onset of the protocol (t = 0 weeks) and at weeks 1-7, week 10, and week 32. Mechanical compression tests made between steel plates within the elastic limit. Following testing, the structural stiffness (slope of the load-displacement curve) was calculated within the linear elastic region. Statistical analysis using JMP (SAS institute, Cary, NC) was performed to detect degradation in weight and stiffness with soak time. A significant difference is indicated by P
