On October 14, 2026, 3DPrint.com published a news brief covering four developments in medical, aerospace metal additive manufacturing, and water treatment. In the medical sector, Myrava (formerly Ricoh 3D for Healthcare) received FDA 510(k) clearance for its 3D-printed patient-specific tissue compensators (bolus) used to precisely control radiation therapy doses. The device is printed directly to conform to each patient's anatomy and treatment plan; its flexible, translucent material enhances wearing comfort and allows for reuse. In aerospace metal additive manufacturing, Australia's AML3D announced its participation in a three-year advanced aerospace manufacturing R&D project, collaborating with an unnamed global aerospace OEM, aiming to elevate the maturity of AML3D's Wire Arc Additive Manufacturing (WAM) technology to meet aerospace tooling production qualification requirements. Meanwhile, Mears Machine purchased a Velo3D Sapphire XC system dedicated to printing copper-nickel alloy (CuNi) components. In water treatment, Canadian researchers developed a low-cost 3D-printed filter cartridge that efficiently removes microplastics from water, demonstrating the potential of additive manufacturing for low-cost customized environmental filtration devices. Value to powder buyers: ① If the AML3D aerospace tooling project enters the qualification phase, it will drive demand for wire arc additive-specific wire and associated metal powders; ② Mears' Sapphire XC dedicated machine focuses on CuNi alloy, confirming the resilient demand for copper-nickel powders in marine and offshore engineering components; powder suppliers may monitor CuNi30-type grades; ③ Medical and water treatment applications are polymer-based, with weak relevance to metal powders.
