4. Conclusion The objective of this study is to assess the PVA material’s performance using different FDM 3D printing parameters. This is intended to establish a baseline for the development of a novel biodegradable material. Based on the findings presented in Tables 3 to 5, it is evident that the maximum force (F) of 133.1641 N is achieved when the layer height is set at 0.2 mm . Subsequent investigations will explore the variation of other interrelated parameters to determine the ultimate set of optimal conditions at which the mechanical properties of FDM 3D printed PVA material are optimized.
