This whitepaper demonstrates how Additive Industries’ ensure in-depth understanding of particle pickup speed in relation to the higher gas flow rates required when scaling up in build size and applied laser power – critical for controlled process conditions. By showing excellent agreement between model and experiment, a solid foundation has been developed to keep up with the rapid development of new materials and the demand for higher build rates. This fundamental knowledge has been used to develop the gas flow design of the MetalFab 420K. Results show a homogeneous flow field with high velocities, with these high velocities being strategically located as close to the process plane as possible whilst maintaining an undisturbed powderbed.
