en.Wedoany.com Reported - Sekisai announced on June 11 that, as a design and manufacturing studio specializing in 3D printing, the light diffusion panels it produced have been used in the interior development of Lexus' next-generation concept car, the "Lexus LS Coupe Concept."

The concept car was unveiled at "Japan Mobility Show 2025," and this collaboration originated from a commission by Calty Design Research, Inc., Toyota's North American design center. Sekisai worked with the CMF (Color, Material, Finish) design team to produce the light diffusion panels applied to the new vehicle.

Sekisai's light diffusion panels are installed in three locations: the overhead console, cup holder, and headrest. According to the company, this design brings a new experience of light and color that cannot be achieved with traditional automotive interiors.

In this project, Sekisai used its proprietary three-color hybrid 3D printing technology to create the light diffusion panels. By precisely mixing three different transparent materials and forming them three-dimensionally, the company achieved complex color gradients and light diffusion effects that cannot be realized with traditional painting or molding methods.

When diffusing light in transparent materials, the shape and material texture have traditionally been crucial. Sekisai added elements of color gradients and subtle transitions to this foundation, creating a new light diffusion method that blends color with three-dimensionality. Furthermore, by using 3D printing technology, the company achieved customized manufacturing where each product has a different appearance while ensuring repeatability.
