Polymer

Definition

A polymer is a large molecule made up of repeating structural units called monomers, which are covalently bonded together. Polymers can be naturally occurring, like proteins and DNA, or synthetic, such as plastics and resins. Their unique properties, including flexibility, durability, and the ability to be molded into various shapes, make them ideal for numerous applications, particularly in pharmaceutical 3D printing where they can be used to create customized drug delivery systems and medical devices.
