This special pen allows the blind to draw

A 3D printing pen is helping blind students at a school in the United Kingdom to draw for the first time.

The pen is by a company called 3Doodler and it creates lines with plastic, which heats and cools rapidly.

This way not only can the students draw in the air, but blind children can actually touch and feel what they have created.

Students say that by using the pen, they have far more control on what they can do. The pen has been in use for a while and has now also received the backing of the Royal National Institute of Blind People, a major UK-based charity.

The 3Doodler pen has been tested for one year with several groups of students with vision loss and their teachers. The pen is extremely user-friendly, and includes temperature settings, audio support for learners and tactile buttons.
