Auburn College’s Nationwide Middle for Additive Manufacturing Excellence (NCAME) is accelerating analysis in steel additive manufacturing by partnerships with Australian-based steel AM specialist Amaero and American shipbuilder Austal USA. These collaborations goal to quickly take a look at superior aerospace powders, similar to Nb-C103 and Ti-6Al-4V, whereas growing dependable materials knowledge for naval shipbuilding. By leveraging NCAME’s end-to-end capabilities, the partnerships ship vital insights in weeks reasonably than months.
Excessive-Throughput Testing with Amaero
Via its collaboration with Amaero, NCAME is evaluating high-cost, high-performance powders like Nb-C103 utilizing a high-throughput method that shortly generates insights into process-structure-property relationships whereas minimizing materials utilization.
With prices as much as $4,000 per kilogram, Nb-C103 is each costly and difficult to check in analysis settings. “We’ve developed a high-throughput, iterative course of improvement method permitting Amaero to supply NCAME with minimal materials and get a fast image of the process-structure-property relationships. The goal is for us to have the ability to flip this round in a matter of weeks in order that the subsequent iteration isn’t slowed by the necessity to ship samples out to a number of laboratories. The enabler right here is that NCAME has the total fabrication to the info worth chain inside our management, enabling us to expedite the printing, testing and characterization to satisfy the wants of the AM business,” mentioned NCAME analysis engineer Scot Carpenter.
The power to quickly generate knowledge is vital for broader adoption of additive manufacturing. “Additive manufacturing affords many options to our nation’s industrial capability however this may be diminished by having to have interaction a number of specialised laboratories to totally consider the process-structure-property relationships,” mentioned Nima Shamsaei, Phillips WestPoint Distinguished Professor and Director of NCAME. “This partnership particularly leverages NCAME’s experience and capabilities to supply solutions inside weeks, versus months or years if outsourced.”
Supporting Protection and Maritime Purposes
NCAME can be working with Austal USA to handle lengthy lead occasions for cast or solid elements, which might take one to 2 years for low-volume orders. Additive manufacturing affords a near-term resolution whereas enabling extra advanced designs and, in some circumstances, improved mechanical efficiency.
“The final word aim of this mission is to determine the correlation between in-situ sensing knowledge and the ensuing defect/micro-structure,” mentioned Connor Headley, analysis engineer for Austal USA. “We’re helping Austal USA in build up materials allowables” — the stress and pressure limits for a cloth — “that are statistically derived knowledge units of mechanical properties for supplies of curiosity,” Carpenter mentioned.
NCAME’s Broader Function in Superior AM
These partnerships construct on NCAME’s ongoing work in advancing steel additive manufacturing for aerospace and protection. In 2025, U.S.-based 3D printer producer Velo3D introduced progress in qualifying C103 niobium and Ti-6Al-4V powders produced by Amaero, following profitable testing milestones carried out by NCAME.
Equally, NCAME has collaborated with Blue Origin to enhance using copper in 3D printing. As a part of the hassle, Blue Origin donated EOS M290 printers designed to handle copper’s distinctive challenges. “Blue Origin just lately donated two EOS M290 to NCAME to assist enhance using copper in additive manufacturing,” mentioned Shamsaei.
