Effect of the Interior Fill Percentage on the Deterioration of the Mechanical Properties of FFF-3D-Printed PLA Structures

Polymers, Journal Year: 2025, Volume and Issue: 17(6), P. 828 - 828

Poly (lactic acid) (PLA), a biodegradable polymer, is widely used in medical applications, particularly for 3D-printed tissue engineering scaffolds. The fused filament fabrication (FFF) 3D printer an available processing tool PLA. nozzle scan pattern and interior fill percentage (IFP) considerably influence the mechanical properties of formed structures may have dominant effects on rates at which PLA deteriorate. When IFP set to low value, such as 80%, internal gaps form within structure, leading different deterioration patterns compared under 100% condition. In this study, we fabricated test pieces with FFF using three patterns. After immersing phosphate buffer saline (PBS) up 120 days, water content was measured underwent tensile testing determine strength, elastic modulus, breaking energy. Both rate uptake varied among fabrication. For gaps, proceeded two stages. faster than that fully filled structures. data obtained study will be useful design applied engineering.
