So We’ve been enjoying our new 3D printer at Lost and Found. The other day a young kid came in and was really scrutinizing what it was doing. The following conversation took place:
Kid: What’s it doing?
Me: It’s printing a 3D object. More specifically, It’s printing a birdhouse.
Kid: ???
I grabbed a sheet of paper and a pencil.
Me: If I draw a straight line across across this sheet all it has is length or 1D. If I write some words and draw a stick figure that requires 2D and is basically what most printers do. This printer can print with length, width, and height creating a physical object. That makes it 3D.
Kid: Wow! So what’s a 4D printer?
Me: Just give it time.
I said this last line with a smile while the kid just nodded sagely not realizing he had walked right into one of my dumb jokes.
