Thinking about future mobility and production engineering

Transport paths of people and goods are the main arteries of our networked society, locally as daily used commutes or globally as international merchant shipping routes on the oceans. Classical transport means, however, no ...

3-D printing of metallic micro-objects

3-D printing has become an increasingly important production method. Researchers at ETH have now developed a new 3-D printing technique by which micrometre-sized objects made of several metals can be produced with high spatial ...

Finding keyholes in metals 3-D printing

Additive manufacturing's promise to revolutionize industry is constrained by a widespread problem: tiny gas pockets in the final product, which can lead to cracks and other failures.

It's too soon to call 3-D printing a green technology

Over the past decade 3-D printing has captured the imagination of the general public, engineers and environmental visionaries. It has been hailed as both a revolution in manufacturing and an opportunity for dramatic environmental ...

3-D printing the next generation of batteries

Additive manufacturing, otherwise known as 3-D printing, can be used to manufacture porous electrodes for lithium-ion batteries—but because of the nature of the manufacturing process, the design of these 3-D printed electrodes ...
