    Abstract

    Systems and methods for neutralizing, and preferably reusing, cleaning solvents (3) for cleaning 3D printed objects (2), wherein at least a part of a residual 3D printing ink comprised in the cleaning solvent (3) can be neutralized by a procedure of residual ink activation, preferably activated and neutralized by polymerization and subsequent precipitation removal before solvent reuse or disposal. Further, the present invention relates to the safe disposal of residual activatable solidifiable inks for 3D printing, in particular in relation to the safe disposal of residual activatable solidifiable inks for 3D printing comprising activatable mono- and/or oligomers, in particular comprising photoactivatable mono- and/or oligomers.
