Melbourne additive manufacturing company SPEE3D has been given the green light by the US Navy to use its metal cold spray technology for use in critical submarine systems.
It’s a first for cold spray additive manufacturing technology and investigation of its capability as a manufacturing method for SUBSAFE-compliant applications, according to a public statement made on May 24.
US Navy has selected SPEE3D’s metal cold spray additive manufacturing technology to develop materials as a part of a Naval Sea Systems Command project related to Expeditionary Maintenance and Sustainment that achieved Submarine Safety Program quality standards.
SPEE3D co-founder and chief technology officer Steven Camilleri said the company, the applied research laboratory of Pennsylvania State University, and the US Navy will work collaboratively to develop an entirely new method to rapidly manufacture existing parts for use in critical submarine systems.
“We are honoured to be chosen and trusted by the US Navy to participate in this groundbreaking project,” he said.
“We have worked successfully with the US Navy in the past and understand the unique challenges they face with the need for manufacturing capabilities that are fast, reliable and easily deployable.”
Submarine parts could be manufactured in hours instead of months if the new manufacturing process meets the rigorous engineering, quality, and safety requirements of the US Navy, according to Camilleri.
Manufacturing of materials, assembly, and testing for the US submarine fleet is tightly controlled with the SUBSAFE quality assurance program designed to ensure the safety of personnel and vessels.
SPEE3D can already manufacture a variety of metals including aluminium 6061, aluminium bronze, and copper.
