Hydras
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.

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.
