3Doodler is the world's best-selling 3D-printing product. It came into existence after the makers felt that the world needed a pen that could make more than just regular drawings on paper. This thought inspired them to create a pen that could actually produce designs in three-dimensional shapes. When the user begins drawing in the air, the pen releases heated plastic which soon dries up to turn into whatever the artist wanted to create. Today the 3Doodler is used by millions of people worldwide. Considered as a pen for all ages, the product is designed for just about anyone who has a creative mind and can make basic drawings. It does not need the support of any software whatsoever. Just hold the pen and let your imagination come to life. From arts class students to amateur artists, everyone considers the 3doodler the ultimate go-to product for 3D design activities. And designing isn't the only thing it does. It also comes in handy during minor repair work.
