| Cold-jet metal 3D printing is reported to be coming to Singapore, with the Singapore Institute of Technology (SP) receiving funding of nearly S $ 250,000 ($ 190,000) from the Singapore National Additive Manufacturing Innovation Cluster (NAMIC) A joint R & D project for SP, NAMIC and Australia's 3D printer manufacturer SPEE3D Additive Manufacturing Research will explore how to 3D-print metal faster with the goal of producing parts 1000 times faster than traditional 3D printing technology.  Combines gas atomization and cold spray techniques The one-year research project combines metal powder production at SP's Advanced Materials Technology Center (AMTC) with the LightSPEE3D 3D printer from SPEE3D, an Australian 3D printing company. AMTC produces custom metal powders using a gas atomization system that uses pressure from an inert gas to force the molten material through a nozzle.The pressure also disrupts the flow of gas to form droplets of metal that cool along the length of the tower to form a powder. This in turn is used as a feedstock for the LightSPEE3D 3D printer.The LightSPEE3D is based on the Cryogenic Three-Dimensional Deposition (SP3D) technology, a cold spray technique in which metal powder is sprayed through a nozzle onto the robot arm's build plate. As the molten powder particles impact the substrate-carrying build plate (or solid particle layer) and cool rapidly, the arm moves along five axes to form a near net shape portion layer by layer.This process requires that the 3D print metal ratio 1000 times faster technology. Asia's first SPEE3D cold-spray metal 3D printer settled in Singapore Australia's SPEE3D is not the only company developing cold-spray additive manufacturing, and in 2013 3D Tiger reported how GE used cold-spray 3D printing and recently GE looked at improvements in cold-spray technology. The first polytechnic studying metal 3D printing This is the first R & D metal 3D printing technology to be awarded to the Singapore Polytechnic Institute to make technology faster and cheaper. "Dr Ho Chaw Sing, Managing Director of NAMIC said:" We are pleased that SPEE3D selected Singapore as its technology development , One of the key hubs for testing and marketing. "In addition, Chaw Sing added the need for a R & D program. "The lack of manufacturing-grade metal printing in terms of production speed, coupled with the cost and quality of raw metal powder materials, is a major hurdle that has forced metal to adopt metal-AM technology." Dr. Rajnish Gupta, Director of Technology Innovation and Business Unit, Polytechnic Institute added: The partnership will "help us make Singapore a global additive manufacturing center." Cold Spray Technology for SPEE3D was invented by Steven Camilleri and Byron Kennedy, and the LightSPEE 3D 3D Printer was installed at Charles Darwin University in Australia in 2017. Byron Kennedy, Chief Executive Officer of SPEE3D, said: 'Singapore is the perfect place to install the first LightSPEE 3D printer in Asia. Together with Singapore Polytechnic Institute, ST Kinetics and NAMIC, we can show the world how high-speed 3D printing revolutionizes manufacturing. ' Article Source: 3D Tiger |
