The Capital Brief | 4DX, AL3 and UNT

4DMedical Limited (ASX: 4DX)

Australian health care company 4DMedical (ASX: 4DX), which recently joined the S&P/ASX 300 benchmark index, is a global medical technology company revolutionising respiratory care with advanced imaging and artificial intelligence.

The company has been on a tear since news came through in early September 2025 that its ventilation-perfusion CT:VQ™ product, a new benchmark in cardiothoracic imaging, had received US FDA approval.

In the intervening period, a steady stream of positive announcements have issued, with a growing number of US Academic Medical Centers (AMCs) moving to adopt CT:VQ™.

The latest AMC moving to deploy 4DMedical’s CT:VQ™ for ventilation and perfusion analysis, the prestigious Mayo Clinic, is consistently ranked the number one hospital in the US. It coming on board is clearly one of the most significant institutional endorsements to date for CT:VQ™.

The initial deployment at Mayo Clinic will support clinical workflow integration and build clinician familiarity with CT:VQ™’s advanced capabilities, with potential to expand to full commercial terms at a later date.

The Mayo Clinic deployment follows the successful commercial rollout of CT:VQ™ at five other leading US AMCs: Stanford, Cleveland Clinic, UC San Diego Health, University of Chicago Medicine, and University of Miami.

This growing AMC list sends a powerful signal to the broader US healthcare market about the clinical relevance and transformative potential of the CT:VQ™ technology.

It eliminates the need for radioisotope and contrast administration, providing superior image resolution compared to nuclear medicine, seamlessly integrates into existing CT imaging workflows. It also opens the way for delivery of reimbursement pathways that support sustainable clinical adoption.

AML3D Limited (ASX:AL3)

AML3D (ASX: AL3) has also released some positive new flow over recent weeks.

This company manufactures ARCEMY® industrial metal 3D printing systems that use a patented Wire Additive Manufacturing (WAM®) process to provide advanced, automated, on-demand, point-of-need 3D manufacturing solutions.

AML3D just recently announced another material US Defense sector-related order. It will see the company manufacture five high demand components for in service trials on US Navy submarines.

This latest order, valued at around AUD2,6 million, will see AML3D leverage its proprietary ARCEMY® technology to 3D metal print five high demand components that are no longer available from the original manufacturer.

It has been signed with BlueForge Alliance, a US non-profit, neutral integrator, supporting the strengthening and sustainment of the US Navy’s Submarine Industrial Base.

The order follows successful hydrostatic testing, by the US Navy, of ARCEMY® 3D metal printed components and is expected to run for a period of approximately 10 months commencing in the fourth quarter of AML3D’s current financial year.

It follows hot on the heels of an announcement by AML3D in mid-March 2026 that it had received a circa AUD$9.9 million order for four ARCEMY® X systems from Newport News Shipbuilding, a division of HII, America’s largest military shipbuilder. These ARCEMY® systems will be supplied from AML3D’s New US Technology Centre in Ohio.

Importantly, Newport News Shipbuilding is a repeat customer for AML3D, with the client set to have a fleet of six custom ARCEMY® X systems on completion of this latest order.
