Stratasys expands availability of RadioMatrix Radiopaque

Stratasys Ltd has announced full commercial availability of its RadioMatrix radiopaque 3D printing material in the United States. This milestone follows initial limited deployments and marks the first time healthcare providers, device manufacturers, and research institutions across the US can broadly access and utilise the material for advanced medical imaging and training applications.

RadioMatrix is the first and only 3D printing material that enables precise control of radiopacity – allowing users to produce patient specific models with repeatable, consistent, and fully tuneable visibility on X-ray based imaging.

Stratasys developed RadioMatrix to support a new era of medical imaging. Its fidelity for computed tomography (CT) phantoms was later underscored by research conducted with Siemens Healthineers, which validated RadioMatrix’s capabilities and accuracy for accelerating innovation in device testing, calibration, and education.

UK based work with partners such as CPI and Beaumont Hospital is already demonstrating the impact of radiopaque 3D printed models in practice, with radio-realistic cerebral angiography phantoms being used to improve the fidelity of imaging based training and create more controlled, repeatable environments for research.

Early research from the Stratasys-Siemens Healthineers collaboration shows that 3D printed RadioMatrix phantoms can closely replicate real human tissue in CT imaging, with deviations reported as low as single Hounsfield units (HU) in critical areas such as grey matter and veins. By combining Stratasys’ Digital Anatomy 3D printing technology and radiopaque materials with advanced imaging algorithms, the partners are demonstrating anatomically realistic, radio accurate phantoms that preserve fine anatomical details and pathological variations while offering a more consistent, ethical alternative to cadavers. These models are expected to improve how radiologists validate and optimise CT protocols and accelerate the development of new imaging algorithms for more precise diagnosis and treatment planning.

‘Providing full availability of RadioMatrix in the US is a major step in providing cutting edge imaging education and training,’ said Erez Ben Zvi, vice president, Healthcare, Stratasys. ‘By giving radiologists and device manufacturers the ability to print ultra realistic, customised radiographically accurate models, we are helping replace traditional phantom solutions and reliance on cadavers with customisable, repeatable, and scalable alternatives.’
