3D pens are innovative devices that allow you to turn your imagination into three-dimensional reality. By extruding molten plastic filaments, these pens let you create 3D objects freely and creatively. <\/p>\n\n\n\n
In this article, you'll learn how they work, what materials they use, their advantages and disadvantages, and how they are applied in education. <\/p>\n\n\n\n
Imagine a pencil that, instead of ink, extrudes molten plastic that solidifies upon contact with the air. That is essentially what a 3D pen does. <\/p>\n\n\n\n
These lightweight and handy devices allow the creation of three-dimensional free-form structures. <\/p>\n\n\n\n
The process involves the controlled extrusion of plastic filaments\u2014usually PLA or ABS\u2014which are melted in a nozzle and deposited in successive layers, solidifying as they cool. <\/p>\n\n\n\n
These pens have a small nozzle through which the printing material is dispensed; it solidifies upon contact with the air.<\/p>\n\n\n\n
3D pens work using a process called fused filament deposition (FDM). <\/p>\n\n\n\n
The device connects to a power source\u2014either an internal battery or a power outlet\u2014and as the user presses the button, the plastic filament is extruded through a heated nozzle. <\/p>\n\n\n\n
The extrusion speed and temperature are adjustable to allow for greater flexibility in creating objects. <\/p>\n\n\n\n
The user guides the pen along a surface, and as it moves, the plastic solidifies instantly, creating a 3D structure.<\/p>\n\n\n\n
