Normally when you print something it's on a flat 2D surface, but thanks to modern technology 3D printing can do so much more.
You might have heard about it before or even seen some cool videos online, but in the Hub Lab, Phil is going to explain the process and fire up his own printer to show you one in action.
The demonstration starts simply to explain how you build things that lock in together, but even more complex and larger things need to apply these ideas too.
These printers were first used in the mid-1980s and they are now so advanced that thye can create everything from houses to food!
The technology has moved on to much bigger things in Ireland - 3D printed houses!!
Laura Hogan from RTÉ News has the story. Layer by layer, a 3D concrete printing machine has been building new homes in Dundalk from the ground up over the last two weeks.
The three social housing units located at Grange Close in Dundalk, will be the first 3D printed homes in Ireland.
