1. A system for drying off residual resin from 3D-printed objects, comprising:
a wash reservoir including a chamber for housing the 3D printed object and containing a wash solvent or liquid solvent adapted to at least partially remove residual residue present in the 3D printer object;
one or more air exchange vents provided between a splash guard or a lid of the wash reservoir adapted to act as an air intake or an air exhaust; and
an airflow module in fluid communication with the one or more air exchange vents and the chamber, the airflow module adapted to:
create a positive or negative air pressure inside the wash reservoir for redirecting airflow to the chamber housing the 3D printed object; and
blowing air out of the chamber or blowing air into the chamber to dry the 3D-printed object.
