  bibo_abstract:
  - Laser Powder Bed Fusion (PBF-LB/M) enables significant performance enhancements
    in tool and mold making via the integration of complex, conformal cooling channels.
    However, high manufacturing costs of monolithic components and material-specific
    defect susceptibility still hinder widespread industrial adoption. Within the
    collaborative project WerKo3D, the scaling, process qualification, and structural
    design of the novel tool steel Printium 13 were successfully investigated to lower
    market entry barriers for additive tooling applications. An industrial batch of
    50 kg of Printium 13 powder was produced via vacuum inert gas atomization and
    thoroughly characterized. Utilizing a Design of Experiments (DoE) approach on
    an SLM 280 system, an optimized process window was established, yielding a relative
    density of about 99.99%. Subsequent heat treatment parameterizations revealed
    a superior mechanical property profile combining high hardness with enhanced impact
    toughness compared to conventional AISI H13 tool steel, alongside ultimate tensile
    strengths up to 1,600 MPa. To reduce build times and material consumption, a segmented
    shell-core tool design was conceptualized and numerically optimized via coupled
    CFD and FEM simulations. The functional demonstrator - a sprue insert for aluminum
    die casting - was additively manufactured without cracking, heat-treated, and
    finish-machined to final dimensions. Furthermore, a two-day training and knowledge-transfer
    program was realized to disseminate design guidelines to industry stakeholders.
    The findings validate the complete process chain from powder atomization to crack-free
    hybrid tool manufacturing.@eng
