Scientists may have just solved one of medicine's trickiest challenges: obtaining human skin.
Usually doctors rely on donations to get skin for vital life-saving surgery and skin grafts, but it can be surprisingly difficult to get hold of spare skin.
Thankfully, a team of Cardiff researchers have worked out a way to '3D print' living human skin—using Lego.

The researchers set out to build an 'affordable' 3D bioprinter out of Lego that could manufacture 'soft biological material' like skin with ease and use it for lifesaving operations.

The research team behind the LEGO skin printer have even shared instructions for how to build it so that anyone can print their own skin.
Of course, this is written for a very knowledgable science and engineering audience but if you can wade through all the gobbledigook then you'll be all set.
This is just the latest advancement in the booming field of synthetic human skin.
Last year, a team of scientists in Tokyo were able to successfully grow living human skin on a robot finger capable of hearing itself.
But more attention was drawn to how 'phallic' the finger looked than to the astonishing scientific achievement.
