A cleaning system for an additively manufactured component includes a tank storing a cleaning fluid. A fluid circuit is operably coupled with the tank. A pump is coupled with the fluid circuit. A manifold is configured to receive fluid from the fluid circuit through the pump. At least one of a coupler defined by the manifold or a hose is coupled with the manifold. The at least one of the coupler defined by the manifold or the hose is further configured to couple with said additively manufactured component.

Cleaning system for additive manufacturing

A method of measuring a characteristic of a material in a structure is the subject of the present invention. A known stress relationship S=TC/J is utilized in practicing the method of the present invention. In the foregoing formula S=strength in p.s.i.; T=torque force in pounds/inch; C=distance to the point of interest in inches; and J=.pi./2r.sup.4 where J is the polar moment of inertia for a circle of radius r (in inches). A drive head is adhesively secured to a segment of the structure to be tested. A known torque force is then applied to the drive head and this known force is translated into a measurement of the material characteristic utilizing the formula indicated. The method may be utilized to test the ultimate shear strength by failing the material or may be utilized to measure strength up to a design criteria without carrying the material to failure. Other material characteristics may also be measured utilizing the known formula set forth above and other known relationships.

A cart bolted to a short bottom section of a ladder carries a winch. A cable on the winch runs over a pulley on a short top section of the ladder and is connected to a carriage having wheels running in channel-like side members of the ladder. The carriage has an adjustable, folding platform and a back which pivots to a horizontal position when the carriage reaches the top of the ladder. A bottom pushbutton control and a top pushbutton control are provided.
