What Are 3D Printing Pens?

3D Printing Pens

Before we dive into the safety aspects, let’s understand what 3D printing pens are. A 3D printing pen is a handheld device that allows you to create three-dimensional objects by extruding molten material through its nozzle. 

This material, commonly known as filament, is heated and fed into the pen, which then cools rapidly to form solid structures. These pens offer a more free-form approach to 3D printing compared to traditional printers, giving users the ability to sketch, trace, and create intricate designs.
