This is the paper train I made with my engraver,with a maximum power of 10W and maximum speed of 1mm/s. It has been equipped with an LCD display, touch screen and digital pen driver to let you customize 3D images in a very simple way. The core structure is aluminum. It has good thermal conductivity and can efficiently dissipate heat generated during printing while maintaining stable operation of the whole machine.
