3D Printing Group

I vote for Solidworks, but that is what I use every day. be aware I'm not sure any FEA software is going to accurately reflect the correct physical characteristics of a 3d printed medium. the direction of print and density and infill will all play a part besides just the material itself.

Any software that outputs a step file

I think it will need another scientific knowledge about how the metal powder can fuse when subjected to laser beam, how long it need time to melt and bond. Knowledge about Sintering process it will be also needed. Solidworks or catia maybe best but the properties of rolled metal compared to sintered metal will be different, the tensile strength for example.

I would prefer solid edge,Solid Edge is a leading industry 3D design software that uses synchronous technology to help accelerate product design, speed up revisions, and improve design data reuse. It includes next-generation design, synchronous technology, sheet metal design, modular plant design, CAD drawing and drafting, cloud-ready design, and built-in Parasolid® software, which is the most widely used computer-aided geometric modeling kernel in the industry.

after all,compared to general-purpose CAD tools, Solid Edge's dedicated sheet metal design features can significantly improve production efficiency. Process-specific commands, such as "Lofted Bends" for ducts, "Part to Sheet Metal" for funnel design, and "Blank Body" for flat pattern drawings, allow for faster sheet metal part modeling.
