Polycaprolactone is widely used in the medical field for biodegradable sutures, drug delivery systems, and tissue engineering scaffolds due to its biocompatibility and slow degradation rate. In 3D printing, it serves as a versatile material for creating prototypes and functional parts because of its low melting point and ease of use. Additionally, it is employed in the production of adhesives, coatings, and packaging materials, offering flexibility and durability. Its ability to blend with other polymers enhances its application in creating customized materials for various industrial uses.
