Hydra Models

The Hydras are our Gantry models, introduced in 2016. In these models we move the heads in the X/Y and the bed only in the Z, allowing for faster print speeds and heavier fixturing.

Comparison

The following chart compares and contrasts the various Hydra models:

The Hydra Series

The Hydra 16A models have hard resolution (with encoder feedback) of 20 microns in the X and Y, and 0.8 microns in the Z in standard mode. In microstepping mode, we can achieve soft resolution of 4 microns in the X and Y. It comes standard with two tool positions, but can take additional yokes to handle more.

There are three models, as detailed above. The differences are:

  • The Hydra 16A-S (standard) has a 250mm Z and stands on the floor, with the following options:
    • Can take a bed at 400x300mm or 600x400mm at 120°C or 200°C, or a sub-ambient bed;
    • Can take the 40W CO2 laser and 5W, 450nm diode laser;
    • Can take the Pick and Place setup; and
    • Can take the 3-Phase and 1-Phase spindle tools.
  • The Hydra 16A-T (tall) has a 500mm Z and stands on the floor, with the following options:
    • Can take a bed at 400x300mm or 600x400mm at 120°C or 200°C, or a sub-ambient bed;
    • Can take the 5W, 450nm diode laser (NO CO2 LASER);
    • Can take the Pick and Place setup; and
    • Can take the 3-Phase and 1-Phase spindle tools.
