WHEN “REAL PARTS” BREAK LEGACY TOOLS Many metal AM teams recognize that they need simulation software that works not just for research, but for their complex high-value production applications. Several commercial software packages exist for simulating the AM manufacturing process, but “real parts” expose the painful limits of traditional simulation approaches. The additive manufacturing (AM) industry is moving toward larger, more complex geometries, and these tools simply weren’t designed for this reality. They crash when models get too large, or they only run if you overly simplify the geometry. Even then, acceptable accuracy will typically be impossible to achieve and run times stretch beyond anything usable in a real engineering schedule. The result is predictable. Teams continue to fall back

Around 2018, many organizations ran their first serious evaluation of metal AM simulation. A shortlist of tools, a couple of benchmarks, some internal debate between design, process and FEA teams, and then a decision: buy one of them, build something in-house, or decide that “simulation doesn’t really help us”. From that point on, the story in a lot of companies has been simple: “We already looked at simulation.” The box is mentally ticked. But the world you are printing in today is not the world you evaluated in 2018. And treating those decisions as final is quietly holding metal AM back. THE PARTS HAVE CHANGED Most 2018 bake-offs were run on modest geometries: coupons, small brackets, simple manifolds. Even on
