3D printing technology, the power of shipbuilding industry transformation
Caterpillar Inc. announced a strategic alliance with German additive manufacturing company FIT AG. Under the partnership agreement, the two companies will focus on co-design and 3D printing of aluminum and titanium parts. The partnership aims to bring together leaders in two areas through strategic alliances to take full advantage of the advantages of additive manufacturing in the field of heavy equipment manufacturing. Additive manufacturing is the 3D printing we often say. At present, this technology has been widely used in the aerospace and medical fields, and its application in the ship supporting field is gradually deepening, and will have a profound impact on the development of the ship supporting industry.
Compared with traditional material removal processing technology, 3D printing technology has the advantage of eliminating the need for traditional tools and fixtures and multiple processing steps to quickly and accurately create complex shapes, thus significantly reducing the processing time. Because of these advantages, 3D printing technology has been applied in the field of shipbuilding and manufacturing, bringing new opportunities for shipbuilding manufacturers. For example, General Electric used 3D printing technology for the manufacture of fuel nozzles, which is not only five times more powerful than conventional technology, but also reduced in weight by 25%. Siemens also applies 3D printing technology to the manufacture of turbine blades. It shows that the turbine blades made by 3D printing technology can operate normally at a speed of 13000 rpm and a temperature of 1200 °C. In addition, South Korea has also made 3D printing technology the focus of future development, and has developed a five-year plan to invest $20 million to study 3D printing and 3D manufacturing of marine and marine industrial equipment.
The development of 3D printing technology will bring new challenges to the ship supporting and shipbuilding industries. 3D printing technology will further promote the optimization of decentralized manufacturing, while improving the level of personalized customization and service response speed of existing decentralized manufacturing, which in turn affects the pattern of marine product matching and related industries. For example, in 2014, Maersk used 3D printers to manufacture spare parts for some ships on container ships. The crew can print out urgently needed parts directly on the ship, which can effectively shorten the delivery time and significantly reduce spare parts storage, goods packaging, air/land transportation, Customs clearance and the cost of chartering and berthing. At the same time, this will also make the existing equipment supply agents distributed in various ports around the world face the challenge of gradually marginalization, and bring new challenges to the existing ship supporting production supply service model.
