The Rostock-Montpellier is a delta 3D printer based on the Rostock mini.
It is focused to print as fast as possible and sustain it for a couple of hour.

Prototype
To accelerate the Rostock and get high speed without replace motors by expensive one, according the Newton's 2nd Law there is 2 things to do :
- The parts in movement have to be lighten. If the mass is divided by two, the acceleration can be multiplied by 2.
- The frictions have to be reduced, less force to move, more accleration.
The platform and the carriage has been redesigned in a way that an existing Rostock can be updated with the Rostock-Montpellier parts.
