Revolutionizing the way military and commercial systems are developed, procured, manufactured and sustained in the field.
Our Patented Process
Before Additive Manufacturing can reach its full potential, several technical barriers have to be overcome. The first barrier is achieving mechanical performance that is consistent with conventionally fabricated materials. SHEPRA, Inc. has developed a patented process to incorporate nanomaterials into the Additive Manufacturing process which improves the mechanical and physical performance of such items.
In addition, to the expertise in developing new materials for Additive Manufacturing, SHEPRA, Inc. through its decades of combined experience has the expertise to understand the value stream leverage points to utilize Additive Manufacturing most effectively in the manufacturing of components for new product development or maintenance and sustainment. This understanding includes new component design, component repair, and tool fabrication.
