Additive manufacturing technology
High quality manufacturing requires consistency, control and traceability. Tight focal length control is critical to consistent and productive laser melting performance. As AM systems become more sophisticated and run at higher powers with multiple lasers, dynamic focusing becomes increasingly useful.
Any production process is only as reliable as the feedstock that it consumes. For additive manufacturing (AM) using metal laser melting, the properties of the powder and the machine parameters that are used to process it are closely related.
Multiple lasers processing in close proximity to one another creates the potential for interaction between lasers.
This article looks at how versatile laser modulation can help to match the mode of energy delivery to the needs of component.
This article looks at the factors that drive the selection of Laser powder bed fusion (LPBF) processing parameters, and how these define an ‘operating window’ in which we must work.
By adopting flexible build strategies in which several lasers work together, they enable faster build rates than single-laser machines. But it is vital that higher productivity is accompanied by high and consistent quality, so that AM components are suitable for long operating lives in demanding applications.
