Historically speaking, lithophanes are images made in porcelain with an etching or moulding process, in which an image is visible when backlit due to the varying thickness of the material.

Multi-material structures, which strategically combine different materials for optimal performance of a component, can also be created via 3D printing. For example, steel automobile parts can be ...

A future where lightweight car parts can be made with a 3D printer is here, thanks to multi-material additive manufacturing research. Researchers at Tohoku University's Institute for Materials ...
