d.i.d. is a scalable 3D-printed pen plotter

While computer printers are readily available, if you’d like a plotting device that drags a pen, marker, or whatever you need across paper to create images, your options are more limited. To fill this gap, studioprogettiperduti has come up with the d.i.d, or Deep Ink Diver.

This scalable pen plotter uses a frame made out of 3D-printed parts, as well as aluminum extrusion, which could be lengthened to support the size of paper that you need. A timing belt pulls the writing carriage back and forth, while a roller advances the paper.

Control is handled by an Arduino Uno and a CNC shield, with a version of grbl that accommodates a servo used to lift the pen.

The materials and electronics used for the plotter are all standard and easy to source. The main frame is made of aluminum extrusion and 3D-printed connections. The motors are all standard NEMA 17 stepper motors and a single SG-90 servo motor. Everything is driven by a cheap Arduino Uno control board that handles the transition from g-code to movement. Furthermore, the software used to create G-code, Inkscape, is open source as well.
