At the site of the 2025 REPMUS (Robotic Experimentation and Prototyping using Maritime Uncrewed Systems) International Technology Event, hosted by the Portuguese Navy in Troia, a global assembly of maritime forces, leading enterprises, and scientific research institutions converged, making it a core platform for showcasing cutting-edge technologies and promoting cross-domain collaboration. As a flagship product of Shenzhen Mingda Technology Co., Ltd., the Mingda MD-600D Large-Format FDM 3D Printer made its debut at the event in collaboration with partner PrimeOut. With its outstanding performance and adaptability, it left a profound impression in the technological exploration of the maritime and defense sectors.

Why Could the Mingda MD-600D Become a "Focal Device" at REPMUS?

The core value of the REPMUS event lies in the deep integration of innovative technologies with the practical needs of the maritime and defense fields—and this aligns perfectly with the product positioning of the Mingda MD-600D. As a fused deposition modeling (FDM) 3D printer focused on "large format, high precision, and high reliability," it meets the technological exploration needs of maritime scenarios and the defense sector from three key dimensions:

1. Large-Format Production Capacity to Solve the "Large Component Manufacturing Dilemma"

Maritime equipment and defense instruments often require various large structural parts, functional casings, or customized components. Traditional manufacturing methods usually face pain points such as "long cycles, high costs, and difficult transportation." Equipped with an extra-large build volume, the Mingda MD-600D can directly print large-size parts without the need for split design and assembly of components. This not only reduces structural weak points but also significantly shortens the production cycle. Whether it is the casing components of maritime uncrewed systems or the auxiliary structural parts of defense equipment, it can complete manufacturing in one go, providing key support for on-site experiments and rapid iteration.

2. High Precision and Repeatability to Meet Rigorous Industrial Standards

The maritime and defense sectors have extremely high requirements for the precision and stability of components; even minor dimensional deviations may affect equipment performance. Through optimized mechanical structure design and an intelligent control system, the Mingda MD-600D achieves high-precision printing and excellent repeatability—the dimensional error of parts printed in the same batch or at different times is always controlled within a very small range, ensuring the consistency and adaptability of components. This feature enables it to be used not only for prototype verification but also for direct production of functional parts, perfectly matching the core goal of the REPMUS event: "integrating technological experimentation with practical application."

3. Strong Compatibility and Durability to Adapt to Complex Application Scenarios

Maritime environments are often accompanied by complex conditions such as humidity changes and vibrations, which pose challenges to the durability and material compatibility of equipment. The Mingda MD-600D has broad material adaptability and is compatible with various engineering-grade materials such as ABS, PLA, PETG, and nylon. It can select appropriate materials according to different scenario requirements (e.g., impact resistance, corrosion resistance, lightweight). At the same time, the overall structure of the equipment has undergone reinforced design, featuring good environmental adaptability and long-term operational stability. Even in high-intensity on-site demonstrations and experiments, it can continuously deliver reliable performance.

From Technology Demonstration to Strategic Collaboration: Mingda’s "Maritime and Defense Innovation Layout"

The debut of the Mingda MD-600D at REPMUS is not an isolated display of a single product, but an important step for Shenzhen Mingda Technology to deeply participate in "additive manufacturing empowering strategic sectors." As emphasized by the Portuguese Navy during the event, "the integration of additive manufacturing in maritime experimentation and defense innovation has become an inevitable trend in industry development"—and Mingda has always taken technological innovation as its core to keep up with this trend:

Collaborating with Partners to Connect the "Technology-Scenario" Implementation Link: By collaborating with industry partners such as PrimeOut, Mingda deeply integrates equipment performance with the practical needs of the maritime and defense sectors. It is no longer limited to "providing equipment" but is more committed to "providing comprehensive 3D printing solutions" to help users solve problems throughout the entire process from design to production.

Focusing on Strategic Sectors to Enhance Technological Adaptability: For sectors with strict technological requirements such as maritime and defense, Mingda continuously optimizes product performance. For example, in the future, it will further improve the equipment’s adaptability to extreme environments and material compatibility, explore the possibility of hybrid printing of metal and non-metallic materials, and provide support for the manufacturing of more complex maritime equipment and defense instruments.

A Promising Future: The Next "Innovative Encounter" Between Mingda and REPMUS

The REPMUS event is not only a stage for technology demonstration but also a bridge for communication and collaboration among global innovators. The debut of the Mingda MD-600D this time not only allowed more international partners to witness the strength of China’s 3D printing technology but also laid the foundation for subsequent cross-domain cooperation. As Admiral Jorge Nobre de Sousa, Chief of the Portuguese Naval Staff, stated, "the core of REPMUS is ‘people’ and ‘values,’ and it is about innovating for the common goals of freedom, justice, and democracy"—and Mingda will continue to take technology as a link, work hand in hand with global partners, and use better 3D printing solutions to empower the innovative development of the maritime, defense, and more strategic sectors.

We look forward to bringing more breakthrough products and solutions to future REPMUS events and jointly writing a new chapter of additive manufacturing innovation with colleagues around the world!
