I think an interesting area will be in how we build things. Why use screws of welds to assemble parts when it can be made in one piece and avoid joints that can fail? Imagine an engine block made of all one piece. It could be made lighter and stronger than anything that we could build now. And with channels built into it some self healing could be incorporated. Parts could be made to tolerances that we can't imagine now. Recycling could have wonderful efficiency levels.
