Become a creator.

Hephestos is an evolution of the Prusa i3, the most popular 3D printer in the RepRap community. It incorporates significant improvements and a more practical and intuitive DIY (Do it yourself) assembly kit. The Hephestos lets you breathe life into your projects: designs, prototypes, figures, accessories, models… Your imagination sets the limit!


A complete, step by step assembly kit.

Our aim with this version was to make the assembly process easy and convenient. To do this, we have simplified the steps and included a more visual guide. We have also conveniently distributed the kit parts into two trays with reference numbers to facilitate part recognition thereby helping you follow the steps.


Convenient, easy and reliable printing.

The Hephestos's primary advantage is the openable cable chains that afford easy cable insertion. These allow the cables to be conveniently stowed to the rear of the printer and above the extruder, where they do not interfere with movement.

These details, together with the knurled knobs that facilitate the levelling of the bed, notably improve user experience. Superior quality toothed-pulleys with bearings constitute another significant improvement and require less assembly time.


100% BQ electronics.

All the components that compose the Hephestos's main electronics are integrated into just one board: Zum Mega 3D. Developed by our hardware team, it has new functionality, improved heat dissipation and optimised motor control. In addition, it has a Micro USB connection and a direct connection to the power supply.


Share, improve, evolve.

Our knowledge and work in BQ contributes to Technological World Heritage: we want people to use, nurture and re-share it with the community. To this end, Hephestos is made from 100% open source hardware which you may modify and evolve as desired. We continue to believe in the growing RepRap community, we share our breakthroughs and place no limits on knowledge. All improvements made to this printer are open.
