Singapore Manufacturers Embrace AI and 3D Printing Through A*STAR Partnerships

Mencast Marine has achieved what certifying bodies Lloyd's Register and the American Bureau of Shipping confirmed as a world first: a fully additively manufactured marine propeller that meets class standards for real-world deployment. The certification, reached through a collaboration with A*STAR, NAMIC, and the Singapore University of Technology and Design, marks a concrete turning point in how Singapore's manufacturing sector is absorbing 3D printing technology at an industrial scale.

The propeller project began as a pilot of Singapore's first 3D-printed marine propeller, with NAMIC and SUTD contributing to its development before Lloyd's Register and ABS issued the class approvals that cleared the technology for marine use. Mr Sim, speaking on the achievement, framed the implications in practical terms: "Additive manufacturing allows us to produce more advanced propeller designs by combining AI-driven design with digital manufacturing. These designs can improve efficiency and reduce fuel consumption for customers."

The shift in capability is significant when set against how the work used to get done. Designing a massive ship propeller once involved weeks of trial and error; on the food and beverage side of manufacturing, planning a single production run could consume days of manual effort. At Coca-Cola Singapore's Tuas plant, robotic systems co-developed with A*STAR now automate complex tasks and improve efficiency, illustrating how the same partnership model is reaching across different industries.

A*STAR's role extends beyond bilateral co-development deals. At the Industrial Transformation Asia-Pacific 2025 event in Singapore, the agency showcased AIMie, an agentic AI framework built to explore how human-AI collaboration can enhance manufacturing operations. Rather than replacing workers, AIMie is designed to work alongside them, positioning the system as a practical tool for the factory floor rather than a research concept.

Singapore's broader manufacturing ambitions are visible in a single benchmark: the country now has five advanced manufacturing facilities, including those operated by Coca-Cola and Infineon Technologies, that belong to the World Economic Forum's Global Lighthouse Network, which recognises best-in-class production environments worldwide.

For the 3D printing community watching industrial additive manufacturing mature, the Mencast propeller certification carries particular weight. Class approval from Lloyd's Register and ABS removes one of the last institutional barriers to deploying printed components in demanding marine environments, and the combination of AI-driven design with additive fabrication that Mencast demonstrated is precisely the integration pathway the industry has been building toward.
