| Huisman, a global supplier and manufacturer of heavy construction equipment for the Dutch construction industry, announced the first successful load test of a 3D printed crane hook For use on offshore lifting operations, the WAIM, an approximately 1,000 kilogram weight hook, This approach is increasingly being applied to the shipping industry.  According to Huisam, Arc Additive Manufacturing is a competitor of traditional steel forgings and castings and the company intends to investigate the potential of other complex commercially viable components. Arc Additive Manufacturing is a metal that has the closest relationship with traditional soldering processes The 3D printing method, which requires a wire stock, is then melted in successive layers using an arc plasma beam. Cranfield University, UK, has been a significant driver of the arc additive manufacturing industry since 2006. However, other projects and companies around the world have developed their own arc additive manufacturing methods.In the Netherlands, the Rotterdam Innovator RAMLAB, renowned for its arc additive manufacturing process, is used to make the famous Damen Shipyards WAAMpeller. The arm used in RAMLAB's arc additive manufacturing was supplied by Valk Welding, another Dutch company that had previously worked with Huisman. Huisman's 3D-printed crane hook is made of high-tensile steel, which can carry 80 metric tons of weight, equivalent to 80,000 kilos, and pass all of Huisman's rigorous quality control checks during the load test. The next step Increase the 3D print weight of the hooks to 2,500 kg so they can withstand heavier loads. Huisman said delivery times can be significantly reduced for larger crane hooks, at a cost comparable to forgings and castings, with more consistent quality. Source: 天工 社 |
