3D printers, scanners, and filaments etc. are old form of technology. I would like to draw your attention towards newest Intelligent 3D pens which are similar to a miniature 3D printer.
This 3D pen is a great option to draw outlines of figures, fill the voids of a 3D printed object and even adjoin two 3D printed figures. You can get a good 3D printing pen online from ‘3D Printers Online Store’.
