When products are printed, they often look like nature intended

Additive manufacturing,is changing not only how things are made, but what is made. In particular, many of the objects on display had an organic look to them. That is no accident. In some cases, designers have deliberately copied nature. In others, they have started from first principles, drawn conclusions (usually aided by clever software), and found that nature got there first. And in some, the decisions have been aesthetic—presumably reflecting an evolved preference in the human psyche for objects that look natural.

...The hole is greater than the parts

That ability to create light, strong structures which have complex internal shapes may well turn out to be additive manufacturing’s killer app. The layering of powders or droplets that are then sintered into solidity, or cured with heat or ultraviolet light, allows spaces to be left inside the product. And if such a space would otherwise collapse, it can be filled with a powder that remains intact during curing and is then washed out or blown away. Even moving parts, like clock mechanisms, have thus been made in one go in a 3D printer.
