ABSTRACT:
The support removal apparatus comprising in combination a retention tank having a manifold assembly comprising a plurality of nozzle heads in hydraulic communication with the discharge side of a pump, collectively configured for agitating an aqueous cleaning solution comprised of sodium or potassium hydroxide, sodium or potassium carbonate, and water; a heating element mounted within the retention tank for heating the aqueous cleaning solution to a predetermined temperature set point; a basket strainer mounted within the retention tank in hydraulic communication with the intake side of the pump to mitigate passage of small rapid prototype parts and residual support material therethrough and into the pump and manifold assembly; a work surface mounted atop the retention tank and having a movable lid fitted with a basket for containing small rapid prototype parts; a thermocouple for maintaining the temperature within a tolerable range for optimum removal of support material; a level indicator to ensure adequate solution level in the retention tank for operability of the pump and heating element; a cabinet having interface controller mounted on an exterior panel thereof for setting timer and heat functions; and a microprocessor having capabilities for making minute adjustments to the heating element via feedback from the thermocouple and controlling operation of the pump and heating element for a pre-set time interval.
