Polymer

A type of material made of long chains of organic molecules, where the chains are made of repeating combinations of atoms. In additive manufacturing, polymer usually refers to plastic materials. Polymers are ideal for additive manufacturing because their molecular structure allows them to be softened with heat to a viscous state that can be extruded, formed by curing liquid polymers with heat or light, or even sintered when in a powdered form. Once fully solidified and/or cured, polymers can be very strong and can be engineered to have a wide range of physical characteristics. Abbreviated as PLA.
