Why this company matters

AMPulse analysis, not a company disclosure

Madde addresses the difficulty and expense of machining hard, brittle materials like silicon carbide (SiC) by offering additive manufacturing systems and services purpose-built for those materials. The company targets semiconductor equipment makers, aerospace and satellite firms, small modular reactor developers, and automotive OEMs that need complex, high-durability components with shorter lead times and lower cost than traditional machining.

The company's core technologies are a proprietary binder jetting process for ceramics and high-speed robotic wire arc additive manufacturing (WAAM) for large-scale metal structures. Madde claims to have developed the first 3D printing system optimized specifically for SiC semiconductor components, overcoming the material's inherent hardness and fragility. For metals, it uses WAAM to produce large-scale parts.

Madde spun off from Hyundai Motor Group's H-Startup incubator in 2023 and maintains Hyundai Motor Group as a strategic partner. The company has raised approximately $10 million from investors including DSC Investment, Schmidt, Atnum Investment, Company K Partners, Intervest, and Hyundai Motor Securities. It secured an $8.1 million Series A round in January 2025 to advance manufacturing capabilities and participated in CES 2025 as a Hyundai partner to enter the U.S. market.

Competitors include Desktop Metal (ExOne) in binder jetting and AML3D and InssTek in WAAM. Madde's differentiation rests on its proprietary SiC binder jetting process and its combination of ceramic and metal AM capabilities under one roof. The key open question is whether the company can scale production to meet the volume and quality requirements of semiconductor fabs and SMR manufacturers, where qualification cycles are long and defect tolerance is near zero.
