Your question is CNC to Additive Redesign. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Redesign a CNC diffuser and fuel delivery sub-assembly for additive manufacturing, justifying your approach across support strategy, de-powdering, lightweighting, post-processing, component consolidation, aero/thermal performance, and cost.
