MADDE Inc

MADDE leverages Silicon Carbide (SiC) to produce advanced semiconductor components such as baffle boats. Unlike Quartz, limited to 800°C, SiC withstands temperatures up to 1,200°C with its excellent resistance to hydrofluoric acid (HF) and high thermal conductivity. These properties make SiC ideal for demanding semiconductor environments requiring both chemical and thermal durability.
Through Binder Jetting 3D printing, MADDE significantly reduces lead times compared to conventional machining while reducing material waste for cost-efficient production. This enables us to deliver high-performance SiC parts with uncompromised quality and reliability, positioning MADDE as a trusted partner for next-generation semiconductor manufacturing.

In the space industry, MADDE produces large-scale (~meter-class) components for launch vehicles using Reaction-Bonded Silicon Carbide (RBSC), while advancing optimized designs and proprietary bonding technologies for each part. For major components such as nozzle extensions, we employ a segmented printing approach followed by bonding with our specialized adhesive.
Our verification shows that bonded 3D-printed parts match or even surpass the performance of traditionally machined counterparts. In addition, we achieve high-precision reflective surfaces through advanced surface machining for SiC mirrors used in satellite communication.

In the nuclear industry where extreme temperatures and long-term stability are crucial, MADDE has developed proprietary technology to produce high-purity Silicon Carbide (SiC). Reaction-Bonded SiC (RBSC), produced using the conventional Liquid Silicon Infiltration (LSI) process, is valued for its density, strength, and cost-effectiveness. However, it inherently contains Free Si, which limits its performance in harsh environments.
MADDE’s specialized process yields components entirely of high-purity SiC by eliminating Free Si. It enhances thermal stability, chemical resistance and long-term durability under demanding conditions. Leveraging this technology, MADDE manufactures nuclear fuel cladding for high-temperature gas-cooled reactors (HTGRs), delivering reliable and future-ready solutions for advanced nuclear applications.
