Fusing dissimilar metals
The Titomic Kinetic Fusion (TKF) process fuses dissimilar metals to produce pipes, valves, and other components. Titomic uses this option to make titanium pipes, and reportedly the results have superior wear- and corrosion-resistance compared to competing products.
Desktop Metal upgraded its system to increase capacity and reduce per-part cost. It will achieve faster printing speeds with a single-pass jetting technology using a powder and inkjet-based approach. The initial printing speed now is 50% faster, equivalent to more than 50 kg of metal per hour.
The MarkForged Metal X Production 3D Printer eliminates the need for casting or forging, CNC milling, and post-production finishing. Users just load a 3D drawing into the user-friendly interface to get started. It can print several different metal grades, too.
Optomec expanded its business model by acquiring Huffman in late 2018, a market leader in software and printing techniques that use metal additive manufacturing to repair gas turbines. This approach to repair worn or broken gas turbines costs less than using new spare parts. The Optomec LENS method can repair metal by reapplying coatings to existing components. Alternatively, when a gas turbine needs a full-part replacement, the LENS system makes it in a shorter time and less expensively than traditional manufacturing methods.
AM propeller blade
Naval Group and Centrale Nantes
France’s Naval Group and Centrale Nantes devised a way to make the world's first hollow propeller blade via metal additive manufacturing. The blade weighed about 660 lbs. and took less than 100 hours to make. It was a demonstration model made at one-third the dimensions of a propeller used on a working naval vessel, but the team aims to produce propellers that are 40% more than this first attempt.
Rapid Manufacturing Technology
Aurora Labs’ Rapid Manufacturing Technology (RMT) has production rates that are 55 times greater than the market speed, thanks to the multilayer concurrent printing (MCP) process.
