    3D printed housing? As a machinist... I’m interested to see the results.

    Same here. I wouldn't trust PLA to do the job, even solid. But 3-D printing metal is here!

    IMO, it seems easier to machine that part though.

    yes, PLA for mock up before he actually machines it. my former company 3D prints metal turbine engine compressor blades, probably other companies doing the same as the tech has evolved.

    What grade aluminum will the housing be machined from?

    6061 or 7075, still sourcing the rubber and making changes to the design as the drawings from the guy who made them I believe left them open...this is what was printed from the original design so far

    Wouldn’t polyurethane be a better material for the bushing? Nice job so far.

    If you can find the right material. Is poly. much stiffer than rubber?

    There are many different options for poly as far as stiffness. Poly lasts longer. You can buy whatever stiffness you want

    Anyone test the shore durometer of the factory bushing? That’s where I would start.

    6061 would be plenty strong, but I know a guy with a pile of titanium
