Structured methods to mature and certify Powder-bed Fusion Additive Manufacturing processes (PBFAM) are in their infancy meaning that numerous process iterations are required to achieve the requisite tolerances and properties. This work will take a holistic look at optimizing the manufacturing process chain for process certification. A demonstration part will be built and evaluated using new geometry and material state optimization methods through PBFAM, heat treatments and bulk machining. Analytical and process optimization tools will be presented including: 1) model-based producibility tool for PBFAM and machining; 2) PBFAM scan path optimization for high material integrity; 3) prediction of thermal distortion; 4) part compensation for distortion and machining; 5) machining consideration and evaluation. The integrated work flow aims to accelerate the process certification by shifting more than 60% of the process iterations to the digital world, thus, reducing the certification time by a factor of three.
