Like the Arduino microcontrollers, the printer will be open-source. The machine features a print area of 140 x 100 x 100 mm, and a print volume of 1,400 cubic mm.

Arduino Materia 101 is, instead, an almost foreseeable and completely expected merging of two of the hobbyist world's most popular toys: microcontrollers and 3D printing.

The centerpiece of the case is an Arduino Uno board, programmed with various code snippets. This board controls a 4988 stepping motor and a Nema 17 motor, responsible for the kinetic movements.
