Abstract
The present disclosure provides methods including obtaining an insert comprising a sieve defining openings each having a diameter of 10 to 200 micrometers; placing a volume of a fluid containing a photopolymerizable composition and a contaminant in the insert; and subjecting the volume of the fluid to a centrifugal force to separate the contaminant from at least a portion of the photopolymerizable composition by retaining the contaminant in the insert and passing at least a portion the photopolymerizable composition through the sieve of the insert to provide a separated photopolymerizable composition. Systems are also provided, including an additive manufacturing apparatus, a centrifuge, and an insert configured to be inserted into the centrifuge. The methods and systems can advantageously assist in reclaiming photopolymerizable composition that has been contaminated, for reuse.
