Madde

MADDE Inc. is a South Korean additive manufacturing company that produces components from silicon carbide (SiC) ceramics and metals using 3D printing. It was spun off from an in-house startup program at Hyundai Motor and incorporated in June 2023. The company positions SiC additive manufacturing as an alternative to conventional machining: because SiC is extremely hard, cutting and other subtractive processing are difficult and costly, whereas layer-by-layer printing simplifies the process, shortens processing time and enables complex geometries.

MADDE serves four stated business areas: semiconductors, space, nuclear, and defense. In semiconductors it supplies high-performance parts for semiconductor equipment, citing cost reduction and faster processing versus conventional methods. In space it prints rocket bodies, noses and nozzle extension sections, as well as satellite mirrors, aiming to cut part counts, lead times and cost. In nuclear it makes SiC components rated for operation above 1,500°C, including matrices/containers for nuclear fuel powder in high-temperature gas-cooled and small modular reactors. In defense it works with domestic and international defense companies and research institutes to raise the maturity of defense-grade SiC parts. Its website also lists subtractive machining alongside additive manufacturing as a technology capability.

The company operates an office and research center at 89 Yeonmujang-gil and a factory at 22 Sangwon 1-gil, both in Seongdong-gu, Seoul. As of April 2025 management said it had completed a fully integrated in-house production line including final post-processing and was moving to scale manufacturing.

Founding story

The company was spun off from Hyundai Motor's in-house startup program and formally incorporated in June 2023, separating from Hyundai Motor Group in August 2023. Shinhoo Cho (Jo Shin-hoo) serves as CEO.

Business model

MADDE manufactures and supplies high-performance SiC and metal components to industrial customers, offering 3D printing-based product manufacturing services from design through fabrication using its own printers and in-house production line, including post-processing.

Traction

MADDE raised KRW 2.6 billion pre-Series A in October 2023 and KRW 11 billion (about USD 8.1-8.2 million) in Series A in April 2025, was selected for TIPA's Deep Tech TIPS R&D program in July 2024 (eligible for up to about KRW 1.5 billion of matching R&D funds over three years), exhibited at CES 2025 as an official Hyundai Motor partner, and reported completing a fully integrated in-house production line including post-processing ahead of production scale-up.

Latest developments

In April 2025 the company closed a KRW 11 billion Series A round with DSC Investment, Schmidt, Atinum Investment, Company K Partners, Intervest and Hyundai Motor Securities, to be used for expanding silicon carbide component production capacity and for domestic and international marketing and distribution channels. Management stated the integrated in-house production line, including final post-processing, was complete and that the company was scaling production and pursuing partnerships to broaden its global customer base.
