Abstract: The invention is a system for drying, recycling, and washing off residual resin from 3D-printed objects. Some aspects of the invention include a system for recycling solvents used to clean the 3D-printed objects in a washing chamber. The recycling system may include one or more solvent reservoirs that store a solvent for cleaning residual 3D-printing material off of 3D-printed objects, a wash chamber adapted to clean the 3D-printed objects, and a solvent recycling module. The solvent recycling module receives a saturated solvent from the one or more solvent reservoirs, evaporates or condenses the saturated solvent to remove residual 3D-printing material from the saturated solvent, and returns clean solvent to the one or more solvent reservoirs of the system.

Abstract: The invention is generally a system for drying, recycling, and washing off residual resin from three-dimensionally (3D) printed objects. Exemplary systems may include a wash reservoir, a fan module, and one or more air exchange vents. The wash reservoir contains a wash solvent and a propeller fully or partially submerged into the wash solvent.

The air exchange vents are provided between a splash guard and a platform/lid of the wash reservoir to act as an air intake when the fan module blows air out of the wash reservoir and as an exhaust vice versa.
