Making our own toys: a little about 3D pens (6 photos + 1 video)
Not only 3D printing: an alternative way to make a figurine of your favorite character. 
3D printing technologies are now used in everything from plastic toys and jewelry molds to entire houses being built from scratch.
Recently, scientists have even learned to print artificial organs for people. But there is another direction, which is not so popular, but is also of interest.
We will talk about 3D pens, which are a tool for drawing with plastic. In skillful hands, real masterpieces can come out of a 3D pen. 
These pens are divided into two types: drawing with cold and hot plastic. What are the differences?
Cold ones work with photopolymers (a resin that hardens very quickly), and hot ones work on plastic. For children, it is recommended to choose 3D pens that use resin. 
There is nothing complicated in operation. You need to fill the pen with the desired material (there are different colors) with which you prefer to draw and plug it into a socket. 
The scope of application of this tool is huge. From ordinary drawings and small souvenirs to full-fledged figurines, dishes or home decorations. 
People online are sharing impressive videos of them making superhero figurines with light-up costume pieces, fixing cups, and modeling. 
There are even specialized channels that talk about building a house for a hamster or creating a case for your phone.
Naturally, to make something truly worthwhile and of high quality, you can’t do it with just a 3D pen. The authors of these tutorial videos also use other tools: drills, sandpaper, soldering iron and other tools to finish the model.
Despite the fact that the material used to fill 3D pens comes in different colors, the manufactured objects are then painted in the desired color.
And although miracle pens are already doing incredible things, allowing you to draw three-dimensional figures and objects, in the future the tool will be improved, which will make it possible to create masterpieces with just one gadget.
