Laser Freeform Fabrication (LFF) processes exhibit advantages over conventional machining especially in terms of short production time and lower production cost for geometries of complex shape with individual design of each part. Thus design engineers who develop parts for aircraft applications are given new degrees of freedom for product innovations and product design customized to mechanical loads. Laser Freeform Fabrication is a new production method for the manufacture of complex shaped freeform parts from those engineering materials which are required in aircraft products. Laser Freeform Fabrication gives rise to new design approaches. Thus three different approaches were introduced and typical application for aircraft parts such as a bracket as part of aircrafts primary structure was suggested. Compared to conventionally manufactured products these items can typically be fabricated much faster, at competitive costs and sufficient quality. Additionally, first analyses demonstrated that a significant weight reduction could be realized by means of topology optimization and the application of Generative Laser Processing. Additional investigations concerning part quality, more efficient process technologies and industrial production management have to be conducted.
