| Recently, Australian metal 3D printing company Titomic has announced the launch of the world's largest metal 3D printer. It is reported that the device is based on the traditional cold spray technology and can print on a scale of 9 meters long by 3 meters wide by 1.5 meters high.  It is well known that cold spray technology is not uncommon in the manufacturing industry because it is often used as a means of coating or repairing parts. However, for Titomic in Melbourne, the principle behind cold spraying can make them better Adapt to more inspirational processes: 3D printing. The new Titomic Kinetic Fusion process was co-developed by CSIRO, the National Science Agency of Australia and Force Industries, using cold spray technology, but used it for 3D printing of titanium alloy parts. This process consists of spraying titanium powder in a chamber where the gas is heated, thereby accelerating titanium particles through the nozzle and ejecting from the gun. The gun is controlled by the robot arm for precise pattern ejection and when the particles are on the surface each other' When they collide, they are bonded at the mechanical level through plastic deformation. Titomic Kinetic Fusion not only differs in the manufacture of metal parts, but also prints these parts on a very large scale. The bus-sized 3D printer can print large titanium components - from golf clubs to complex aircraft wing components. It also Metal bicycle frame can be printed in about 25 minutes. In addition to its size, the company's 3D printing process is also running at an alarming rate. According to Jeff Lang, chief technology officer and chief technology officer of Titomic, Titomic's 3D printer can print about 45 kilograms of material per hour, compared to the current market. The fastest 3D printers are 10-100 times faster. In addition, these fast-printing objects are about 34% stronger than conventional titanium. Titomic's process can achieve zero waste, using only the amount of metal powder needed to minimize environmental impact and costs. 'We can make parts cheaper,' Lang said. 'This provides the industry with an opportunity to use titanium more cheaply.' , also opens up opportunities for us to export high-quality components around the world. Source: 3D Tiger |
