The “Bojan” project is a DIY inkjet printer that users can assemble, repair and customise. Unlike closed commercial printers, which are difficult to repair and often treated as disposable products, “Bojan” is designed as an open mechanical and electronic system.

Users can observe the printhead moving along its axis, the motor feeding the paper and the electronics controlling the printing process, while also modifying individual parts to suit their needs. The construction is based on standard components and 3D-printed brackets, while the printing format is determined by the length of the rods selected by the user.

“Bojan” therefore functions as an accessible platform for experimentation, straightforward maintenance and personalisation, while encouraging a better understanding of technology and extending the device’s lifespan.
