It uses differential stress caused by a gravitational field on a working fluid to generate unidirectional output flow, regardless of the direction of travel of the system piston.
A constant waterfall in effect.
200 to 400 microns (0.20 to 0.40 mm).
Will section design to enable printing on a machine with 120x120x120mm build volume hence images only for now.
Those with CAD capability or larger build volumes let me know and I will send the STL's your way as is.
