3D printing is exciting, but it’s never going to revolutionise the world of manufacture on its own.

Today’s invention is a niche application of this technology.


Bracelets and other items of jewellery are often hard to fit precisely.

The semi-permanence of this kind of approach could substitute for tattoos. Also, engaged couples could wear rings that were physically irremovable (or at least tamper-evident).
