A man called Noel Murphy brought in a 3D printer he works as a computer technologist.
He firstly showed us a video of his business flying a 100 Drones lighting with music being played by an orchestra.
Then he brought us out to the 3D printer and explained how it worked. When he was finished talking about the 3d printer he said he would pass around an elephant that he printed once.
When everyone had passed it around, he said he would print a whistle. It took an hour and twenty minutes to do. The whistle worked really well. It was a very interesting visit.
