Abstract
A method of forming an orthodontic aligner from an aligner digital model, the method comprising the steps of: three-dimensionally printing an intermediate structure comprising fused filaments from a biocompatible thermoplastic according to the aligner digital model via fused deposition modelling; coating the intermediate structure with a biocompatible translucent photopolymer; and irradiating the coating with ultraviolet light to cure the coating on the intermediate structure, thereby forming the orthodontic aligner.
