Back in 2013, a curious invention surprised fans of 3D printing: it was 3Doodler, a pen that allowed you to create three-dimensional designs by drawing in the air. To do this, the device extruded a hot plastic material through the tip, and the user could shape and model it to create small sculptures.

Now, 3Doodler has released a new device specially designed for younger children. It's called  3D Build & Play and it allows preschoolers to start experimenting with 3D printing, developing their creativity, and training their fine motor skills.

3D Build & Play is a 3D printing pen adapted for use by children from four years of age in a completely safe way. Unlike the original model, the preschool version is wireless to make it easier to use.

The material used by the device is brightly colored plastic that contains no toxic ingredients or BPA. The plastic comes out when the child turns the crank of the pen and its temperature is not too high to avoid burning the fingers.

Kids can use the device to create their own designs from scratch, but 3D Build & Play also includes different molds and fun backgrounds that help them bring their creations to life.

At the moment, 3D Build & Play is only for sale in the United States at a price of $ 29.99, but it is possible that it may be purchased through Amazon soon like the other 3Doodler models. 

If this device catches your eye, the 3Doodler Adult 3D Printing Pen is for sale on Amazon. There is a model for children called 3Doodler Start, aimed at children older than 3D Build & Play. In addition, there are also for sale other pens from other cheaper brands from about 26 euros.
