How does a 3D pen work?
Can you explain to me how a 3D pen works?
Certainly! A 3D pen works by heating up plastic filament to its melting point and then extruding it through a small nozzle at the tip of the pen. As the molten plastic exits the nozzle, it quickly cools and solidifies, allowing the user to create three-dimensional objects by drawing in the air.
