Laser metal fusion is an additive manufacturing method where a workpiece is built up gradually in a powder bed. To do so, a laser melts down the metal powder in material layers precisely at the points specified by the component’s CAD construction data. The process is therefore often known as metal 3D printing/3D printing; the terms laser sintering and laser metal fusion are also common in the industry. The process is optimally suited for the series production of geometrically complex parts with delicate internal channels and cavities that cannot be produced using conventional processes such as turning or milling or can only be produced ineffectively. Components that exhibit high stability, as well as low weight, are created using industrial 3D printing – this is particularly beneficial for lightweight design or customized implants and prostheses. Furthermore, laser metal fusion is a sustainable production method, as, compared to ablative processes, no chips (and therefore little excess material) are created. With almost two decades of experience in additive technology, TRUMPF provides complete packages for powder bed processes that are mature for the industry – consisting of machines, services, and digitalization from a single source. From part identification to the finished product and beyond – we cover the entire process chain for you.
