The family were at a pub for my wife’s birthday. I mentioned this to the waitress when we ordered our puddings, and when they came out so did a candle with two waitresses singing ‘Happy Birthday’. And then we all started singing, and then also the diners in our section, much to my wife’s embarrassment! A few minutes later one of the diners came over to our table and gave my wife this orange thingy he’d made using a 3D printer. He was a very chatty guy, a Geordie. I got the impression he occasionally gave these away.
The video on the right shows you how complex an object can be manufactured using 3D printers.
