3D Printing in STEAM

TCS TK-2nd grade students have been learning about how 3D printing works. They discovered that the printing filament is melted and laid down in layers, forming the objects made by the printer. To demonstrate how this works, the students rolled out thin ropes of play-dough to simulate filament, and then they laid down the play-dough strips the same way a 3D printer would to make a cup or bowl using this method. The students then designed a toothpaste tube squeezer to print using the 3D printer. To show them how the printer would do this, they took ropes of play-dough and formed the shapes that will be crafted in the 3D printed object.
