metal

With technologies like 3D printing, scientists can now replicate and enhance that natural design principle in metals, polymers, and other substances to achieve effects that were previously out of reach.

Molten metal glows hot on a conveyor belt, illuminating the faces of busy and attentive workers.

The yellow metal is having its third breakout in the past 50 years, and the last two times proved an expensive bust.

Such strong cultural affinity for physical gold, particularly jewellery, means the appetite for the noble metal is unlikely to be dented in the long term, despite the short-term moderation, say experts.

So if you’re looking to avoid areas where sentiment is overly ebullient, steer clear of metals and AI stocks.
