Poly(D-lactide) (PDLA) is widely used in the medical field for biodegradable sutures, implants, and drug delivery systems due to its biocompatibility and controlled degradation properties. It is also employed in the packaging industry to create environmentally friendly materials that decompose naturally, reducing plastic waste. In 3D printing, PDLA serves as a sustainable filament for producing durable and biodegradable prototypes and end-use parts. Additionally, it is utilized in agriculture for mulch films that enhance crop growth while minimizing environmental impact. Its versatility and eco-friendly nature make it a valuable material across various industries.
