Yes, you need to do a deep dive into LCA and make sure it is region specific, or , normalized for input electricity generation type basket. One thing that I have noticed about 3D printing is the high electricity amounts needed. BUT, this needs to be baselined to a component that is traditionally manufactured. You could find a small specialist part studio and ask them to study their parts that are made (without 3D printing) and then 3D print some and check both LCA results. I guess, this result will be highly part type specific. So you need to figure that out too for a more generalist conclusion. Or just throw out the notion of even trying to be generalist. Anyway, that's like my 2 minute thoughts on this. I guess the goal is using less energy and promoting decentralized specialist manufacturing to make the decentralized economy stronger.
