The gas manufacturer Linde will present several gas technologies at the Formnext trade fair. The focus will be on a customized gas combination for 3D printing copper parts, a test lab for powder atomization and a solution for the cold spray process.
The ADDvance Laser230 gas mixture, along with oxygen control, is expected to improve copper 3D printing. Copper is valued in aerospace for its thermal conductivity, but is challenging for 3D printing because of the reflection of the laser. ADDvance Laser230 was developed in collaboration with ArianeGroup specifically to print high-quality copper components.
In a newly established test lab, powder manufacturers can investigate various process parameters in powder production under real conditions. High-speed cameras and schlieren methods can be used to analyze gas mixtures, volume flows, pressures and temperatures. As a result, powder properties can be improved.
A further development of the cold spray process enables process parameters to be monitored for the first time. The LINSPRAY Connect solution ensures a safe and stable gas flow and warns of irregularities.
With the virtual reality animation Hot Gas Atomization, Linde demonstrates how powders can be atomized even finer using preheated gases.
