seemingly endless possibilities
3d printing metal parts makes an old manual machinist like me nervous. If I can make 10 more years maybe I wont have to worry anymore

My parts guy at the local dealer has one, gives me hope and inspiration to make some parts. But the alloy, mids, clamps, housing, lower pan, etc , if it can take it could lighten the package.

That powdered sintered aluminum is terrible for any strength purpose. Good for a cheap manufacturing purpose without casting, but terrible for strength.
"Ductile as titanium". Yes, that's because titatium doesn't flex at all. As soon as it stresses, it cracks. Not like some good steel that will bend all over, and never crack. Think of the little piece of flat stainless steel that a garage door opener uses to clip to your sun visor in your car... That will bend and bend and bend and never break. Then look at the steels they use for large ships. An oil tanker going over 50' waves will twist and bend, and never break. Look at a piece of sintered aluminum casting, drop it on the floor and it shatters.

I'm pretty smart with the metals -

It's been used for motorbike frames, electric.
Well if it's not up to the task that's not good

Motorbike frames? Really?

Have you seen any of the AvE videos on youtube? When he analyzes sintered aluminum, he goes off. He's pretty hilarious.
I've also had a couple engine case covers that were sintered aluminum. They're absolutely impossible to weld after they've broken. So many contaminants in the inside of the metal. It's like hamburger meat instead of a solid chunk of steak.
