North Star Imaging, a supplier of industrial X-ray and computed tomography systems, has published an article on using industrial CT to inspect implantable medical devices made by additive manufacturing. The piece explains how CT scanning can examine 3D-printed implants for internal porosity, check whether printed lattice structures match their intended geometry, and detect powder left trapped inside parts after printing. It also reviews the regulatory side, outlining FDA guidance and ASTM standards relevant to inspecting these additively manufactured implants. The article serves as both an educational overview and promotion of the company's CT inspection capabilities.

In-House or Outsourced Scanning? A Decision Framework for Aerospace Suppliers
North Star Imaging has published guidance for aerospace suppliers weighing whether to bring digital radiography and computed tomography inspection in-house or send it to an outside provider. The company's view is that most suppliers are better off outsourcing until two conditions are met: a system would be kept busy for roughly half of available production hours on a steady, repeating mix of parts, and the supplier has or can recruit a NAS410 Level 3 to take ownership of the process. Below that usage level, the article argues, outsourcing is nearly always the cheaper option.
