Abstract
The present invention relates to a high resolution additive manufacturing method, including: creating a rigid shell of a stable material on all surfaces except for a sprue of a three dimensional (3D) polymer part using a chemical vapor deposition (CVD) process which includes: depositing the stable material at a process temperature of 100° C. or less, and operating at, or near, atmospheric pressure; and removing the 3D polymer part by accessing the inside of the rigid shell through the sprue to allow dissolution of the 3D polymer part, thereby leaving a replicated rigid shell of the stable material.
