January Special Focus Issue: Design for Additive
In this Special Focus Issue of Digital Engineering, learn about the latest advancements in design for additive manufacturing, including new software tools, additive in automotive, custom medical devices, and more.
Stratasys Ltd. shares full commercial availability of its RadioMatrix radiopaque 3D printing material in the United States. This milestone follows initial limited deployments and enables healthcare providers, device manufacturers, and research institutions across the U.S. to access and utilize the material for advanced medical imaging and training applications.
RadioMatrix is a 3D printing material that enables control of radiopacity, allowing users to produce patient-specific models with repeatable, consistent, and fully tunable visibility on X-ray based imaging. Stratasys developed RadioMatrix to support 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.
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 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 consistent alternative to cadavers. These models are expected to improve how radiologists validate and optimize CT protocols and accelerate the development of new imaging algorithms.
“Providing full availability of RadioMatrix in the U.S. is a major step in providing cutting-edge imaging education and training,” says Erez Ben Zvi, vice president, Healthcare, Stratasys. “By giving radiologists and device manufacturers the ability to print ultra-realistic, customized radiographically accurate models, we’re helping replace traditional phantom solutions and reliance on cadavers with customizable, repeatable, and scalable alternatives.”
