CrazyBuy Pla Filament 10 meter each Mix Color PLA Filament 3D Printing Filament(10 pack)

The 3D Pen for professionals works like a hand-held version of a desktop 3d printer. The working process of the 3D pen is that when you draw with the 3D pen it extrudes heated plastic which instantly hardens into a solid structure. Therefore, this feature allows you to draw any 3D shape possible. You are limited by your own level of imagination. The plastic filament in the 3D pen is heated and as you move the 3D pen in any direction while using it, the filament rapidly cools down making sturdy objects capable of standing alone. This 3D pen is perfect for working professionals like architects, designers and model makers.
