Strengthening Polylactic Acid by Salification: Surface Characterization Study.

Polylactic acid (PLA) is one of the market's most commonly used biodegradable polymers, with diverse applications in additive manufacturing, specifically fused deposition modeling (FDM) 3D printing. The use of PLA in complex and sophisticated FDM applications is continually growing. However, the increased range of applications requires a better understanding of the material properties of this polymer.

Multi-Parameter Optimization of 3D Printing Condition for Enhanced Quality and Strength.

Fused deposition modeling (FDM) 3D printing is the most common type of additive manufacturing available in both research and the industry. Due to the rapid development of 3D printing, there is now a significant need to fabricate parts with with respect to cosmetics, precision, and strength of the final products. This work is focused on finding the optimal printing condition for a commercially available 3D printer and filament material (i.
