      abstract     = {In laser-based additive manufacturing of Ni-based
                      superalloys, significant progress has been made in recent
                      years in terms of possible dimensions and geometric design,
                      as well as in terms of improved mechanical characteristics.
                      In the field of gas turbines, this enables now targeted
                      repair and the realization of novel component designs by
                      means of laser-based processes such as direct laser
                      deposition or selective laser melting. In the case of
                      ceramic materials, the necessary high processing
                      temperatures and the lack of ductility of ceramics often
                      lead to high local stresses and crack formation even in
                      relatively small structures. This makes it difficult to
                      build defect-free components and still restricts the range
                      of applications.In the field of gas turbine applications,
                      however, there are microstructure requirements, particularly
                      for ceramic thermal barrier coatings, which can in principle
                      be met by laser-based additive manufacturing. Due to the
                      high demands on the thermal shock resistance of the
                      coatings, the presence of porous areas or segmentation
                      cracks, for example, can not only be tolerated, but supports
                      the function and lifetime of the coatings. In this
                      contribution, a novel laser cladding process (Clad2Z) for
                      the deposition of columnar structures is presented, which
                      can be used for localized fabrication and repair of thermal
                      barrier coatings [1]. The stability and durability of the
                      so-prepared TBCs were investigated under realistic gradient
                      conditions in burner rig tests. The durability and failure
                      mode qualify the coatings as at least equivalent to
                      conventional TBC systems.[1] “Additive manufacturing of
                      columnar thermal barrier coatings by laser cladding of
