Device and method for post-processing resin-based parts that are manufactured by means of 3d printing

A device for post-processing resin-based parts that are manufactured by 3D printing, wherein said device comprises:

• a cleaning tank that houses a cleaning solution wherein a printed part is immersed and resin particles are emulsified;
• a reactor comprising one or more polymerization elements that activate an initiator contained in the emulsified resin in the cleaning solution, thus solidifying said emulsified resin;
• a filter unit that filters particles from the solidified resin;
• and
• a flocculation module fed by the cleaning solution with the emulsified resin solids, wherein said flocculation module comprises one or more flocculation elements that bind the solidified resin into particles or into a group of particles before passing through the filter unit, wherein the flocculation module comprises a flocculation conduit, wherein said flocculation conduit comprises an external conduit that has been sized to channel the cleaning solution with the solidified resin immersed in the same.
