3D Printed Pistons are Real

[Dallas L.]

I knew this day would come soon, and now it’s here. I suspect 3D heads will be next, followed by a full block.

A 3D block wouldn’t require a head gasket. Yes special tools for valve+spring installation as well for pistons, but that’s a small price to pay for eliminating an engine weak point.

Didn’t know where to post this so...
