Additive Manufacturing Solutions in the United States Marine Corps

Abstract

This project conducts a cost benefit analysis, to systematically examine the relative strengths and weaknesses of the current method of obtaining original equipment manufacturer (OEM) parts by the Marine Corps versus additive manufacturing alternatives. These alternatives include the established method of Extrusion and the emerging technology of continuous liquid interface production (CLIP). The findings from the cost benefit analysis show a cost advantage for additive manufacturing at the production level with a substantial edge given to CLIP in three of four scenarios examined. Based on our methodology and findings, we recommend the Marine Corps build a data repository of (blockchained) printable files as quickly as accuracy allows. Once complete, the Marine Corps can continue to use the Fortus 250mc and other previously purchased models. When the repository outgrows the capability of the Fortus machines, it can move to Carbon 3D or a similar technology and expand the capability across the Marine Corps.
