Abstract: A stabilization apparatus for reducing vibration of a 3D printer during operation thereof. A stabilization apparatus features a stationary framework having a base seated atop a support surface and spanning a greater two-dimensional footprint than the 3D printer. One or more flexible elongated suspenders each has one end connected to a respective anchor point each defined on the supportive framework at a respective location of elevated relation to an underside of the base. Another end of each suspender is secured either to the 3D printer itself, or to a floating support atop which the 3D printer is placed. The 3D printer is thereby supported in a floating position of suspended relation to the stationary framework of the stabilization apparatus.

Abstract: A towable implement features a frame, a pull tongue extending longitudinally forward thereof for towed conveyance of the frame over underlying ground, and a working blade lying transversely of the longitudinal direction, said blade being operable to engaged the underlying ground to perform a working operation thereon. The blade is selectively tiltable about a roll axis to adjust an angular position of the blade relative to the underlying ground to enable performance of different working operations thereon. A series of rigid fins are distributed discretely along a width of the blade in a direction transverse to the longitudinal direction, and each rigid fin protrudes downwardly beyond a reference plane occupied by the lower working edge of the blade. In the working state of the blade, at least one of said rigid fins engages said underlying ground in penetrating fashion to perform a rudder-like action helping maintain a straight travel direction of the implement.

Abstract: Vehicles or implements feature walking beam assemblies each having a front wheel and rear wheel carried adjacent opposite ends of the walking beam on opposite sides of a pivot point thereof. The conventional single beam is replaced by a split beam arrangement in which front and rear beams are pivotal relative to one another by an actuator, whereby changing the angle between the front and rear beams lifts or lowers the main pivot of the walking beam in order to adjust the height of the respective side of the vehicle frame. The split walking beam can be used to adjust the tilt angle of a scraper blade or other ground working arrangement in a land leveler or other earth working machine.
