      abstract     = {Strong efforts are made internationally to optimize the
                      process control of laser additive manufacturing processes.
                      For this purpose, advanced detectors and monitoring software
                      are being developed to control the quality of production.
                      However, commercial suppliers of metal powders and part
                      manufacturers are essentially focused on well-established
                      materials. This article demonstrates the potential of
                      optimized process control. Furthermore, we outline the
                      development of a new high temperature structural steel,
                      tailored to best utilize the advantages of additive
                      manufacturing techniques. In this context, the impact of
                      production-induced porosity on fatigue strength of
                      austenitic 316L is presented. Additionally, we discuss the
                      first conceptual results of a novel ferritic steel, named
                      HiperFer (High Performance Ferrite), which was designed for
                      increased fatigue strength. This ferritic, Laves
                      phase-strengthened, stainless steel could be used for a wide
                      range of structural components in power and (petro)chemical
                      engineering at maximum temperatures ranging from about 580
                      to 650 °C. This material benefits from in situ heat
                      treatment and counteracts process-related defects by
                      “reactive” crack obstruction mechanisms, hampering both
                      crack initiation and crack propagation. In this way,
                      increased fatigue resistance and safety can be achieved.},
