Abstract
A novel thermopolymer material adapted for use in thermal stereolithography. More particularly, a thermopolymer material comprising a mixture of: a low shrinkage polymer resin; a low viscosity material such as paraffin wax; at least one microcrystalline wax; a toughening polymer; a plasticizer. Alternative embodiments further include components to improve the materials ability to transfer heat and to improve strength. The subject material, together with the described process greatly reduce part building distortions while retaining desirable toughness, strength and jetting properties.
