Adoption of
3D Printing Technology
The KD-Q1 is the first KuraDa product to adopt 3D printing technology. Compared to traditional SM technology (Subtractive Manufacturing), AM technology (Additive Manufacturing) offers a high degree of design freedom, making it possible to manufacture products with complex internal structures.
■3D Printing with HP Jet Fusion
The parts of the KD-Q1 are manufactured using HP's Multi Jet Fusion method. This technology sprays high-precision liquid agents onto powder material, forming layers by adding heat. This allows for the mass production of complex-shaped parts quickly and with high precision.
■Adoption of PA12GB for the Housing Material
The KD-Q1 uses PA12GB (polyamide 12 glass bead filled) material. This material, which contains 40% glass beads based on PA12, has high tensile strength and durability, maintaining its performance even after long-term use. It also shows resistance to chemicals, lightweight properties, and excellent vibration absorption.

Partnership with SOLIZE
SOLIZE Corporation is a leading Japanese company specializing in digital engineering and 3D printing technologies, with over 30 years of history. They offer innovative solutions in areas such as 3D CAD engineering, model-based development (MBD), and transformation consulting for product development.
We have partnered with SOLIZE, and all parts of the KD-Q1 are manufactured by SOLIZE.
Ultra-Responsive Diaphragm
(URD Driver)
The KD-Q1 is equipped with a 53mm dynamic driver called the "URD Driver". Using a thin PET diaphragm and OFC voice coil, it achieves light weight and high responsiveness, significantly improving the characteristics of the low-frequency range.
Key features include:
■Lightweight Diaphragm
The PET diaphragm is made very thin, achieving both light weight and high responsiveness.
■OFC Voice Coil
The adoption of the OFC voice coil increases the mass of the vibration system, lowering the f0, while the thin diaphragm minimizes the increase in mass, balancing the overall weight and damping ratio. The OFC voice coil has about 30% higher conductivity than CCAW (Copper Clad Aluminum Wire) voice coils, leading to better responsiveness due to lower resistance.
3D-Sewing Earpads
The KD-Q1's earpads are entirely sewn by skilled artisans in Japan. These 3D-sewn earpads are crafted by cutting low-resilience urethane into three-dimensional shapes and ergonomically designed to naturally fit the head. Thanks to Japan's exceptional craftsmanship, the earpads effectively minimize sound leakage and evenly distribute pressure, providing an excellent acoustic experience. Additionally, the parts that touch the ears are made from highly durable protein leather, ensuring lasting comfort even during extended use. This design, which combines the quality and craftsmanship of Japan, achieves both comfortable wear and balanced sound performance.
