Tokyo Ink Launches Japan's First FDM-Compatible Plastic Scintillator Filament

Tokyo Ink Co., headquartered in the northern area of Tokyo, has announced an exciting development in the field of 3D printing. Starting August 1, 2025, the company will offer the LumiNade® 3DP filament, a novel scintillator filament tailored for FDM (Fused Deposition Modeling) 3D printers. This product is particularly significant as it represents the first foray into the market for a plastic scintillator filament in Japan that is compatible with FDM printing technology.

The LumiNade® 3DP filament is based on the same composition as the proven LumiNade® product launched in 2017, highlighting its robust track record. Combining advanced material blending and dispersion techniques with innovative filament processing technology, Tokyo Ink aims to open new avenues for simple and efficient scintillator fabrication.

The transition to 3D printing offers considerable advantages over traditional injection molding methods, especially for low-volume production. This flexibility allows for intricate shape designs and rapid prototyping, making it an excellent fit for the educational and research sectors. Universities, research institutions, and medical facilities can utilize this product to enhance their studies and projects.

Moreover, the versatile LumiNade® 3DP filament lends itself to decorative applications that capitalize on visual effects, such as interior designs utilizing black lights. As researchers and designers experiment, the potential use cases continue to expand, encouraging creativity in applications that require scintillator materials.

To showcase the LumiNade® 3DP filament, a demonstration will take place during the 62nd Isotope and Radiation Research Presentation Conference, set for July 2-4, 2025, at the Miraikan (National Museum of Emerging Science and Innovation) in Odaiba, Tokyo. This exhibition follows Tokyo Ink's successful presentations at the 38th Annual Conference of the Japan Society of Applied Physics in January 2025 and the 72nd Spring Meeting of the Japan Society of Applied Physics held in March 2025. Attendees can expect not only a display of the product but also live demonstrations of how to create scintillators using FDM 3D printers, inviting participants to experience firsthand the novel possibilities in scintillator fabrication.
