New Era in 3D Printing: Lumined® C 3DP Filament

Tokyo Inki Co., Ltd., a leader in color chemistry based in Tokyo, Japan, is set to unveil its latest innovation, the Lumined® C 3DP Filament (PSFC-250), on August 3, 2026. This new filament boasts advanced plastic scintillator functionality that enhances the clarity of 3D printed objects, addressing prior limitations in transparency seen in its predecessor.

Originally launched in August 2025, the first model of Lumined® 3DP Filament provided significant benefits but had slight limitations in clarity due to material and manufacturing constraints. The new C 3DP version is designed to overcome these challenges, allowing for a much higher level of transparency in even thicker printed items. The latest advancements promise not just to maintain the original printing capabilities but also illuminate a clearer pathway for practical applications in research and education.

Performance Features

One of the standout elements of the Lumined® C 3DP filament is its ability to maintain scintillator properties while improving clarity. This makes it ideal for various applications where radiation detection is crucial, including experiments, educational models, and prototypes. The filaments are specifically crafted for use with FFF (Fused Filament Fabrication) 3D printers, ensuring that users can leverage this new material with existing technology in their labs or classrooms.

Key Advantages:

• - Improved Transparency: The new formulation and optimized manufacturing processes offer significantly enhanced clarity compared to previous products, ensuring optimal light penetration in thicker printed components.
• - Versatility for Education and Research: Whether creating scintillator components for radiation detection or educational resources, 3D printed designs can be crafted without needing complex molds.
• - Stable Print Quality: Continuing to use polystyrene ensures that the stability and consistency of print quality remain high, making it perfect for research demanding exact replication of shapes.
• - Easy Adaptation: With a filament diameter ranging from 1.65 to 1.75mm, the Lumined® C 3DP filament is compatible with most standard FFF 3D printers, allowing for an easy transition into current workflows.

Background of Development

The innovation of the Lumined® C filament arose from direct feedback from users of the original Lumined® 3DP filament, who consistently expressed a strong desire for improved clarity. Addressing these concerns, Tokyo Inki committed to improving formulation and production techniques, resulting in a filament that not only enhances visibility but also maintains the functional advantages of the earlier model — crucial for tasks such as radiation detection and educational demonstrations.

This newfound ability enables users to explore previously unimaginable design possibilities in their 3D printing projects. With the Lumined® C 3DP filament, you can now produce customizable and functional prototypes that resonate with the educational needs of various fields.
