Abstract: The present disclosure is directed to a method of altering chemical properties of an in-process resin used with a 3D printing apparatus. The method includes monitoring the in-process resin using an imaging spectrometer, comparing the in-process resin and a model using one or more spectrums from the imaging spectrometer, and diluting the in-process resin with a diluting resin.

Abstract: A method is provided for maintaining resin in a system including a main feed tank and at least one vat, each of the at least one vats associated with a 3-D printing machine. The method includes the steps of: transferring resin from the main feed tank to the at least one vat; operating the associated 3-D printing machine in a build cycle; returning the resin from the at least one vat to the main feed tank; and repeating in a cycle the steps of transferring the resin, operating the 3-D printing machine, and returning the resin.
