The present disclosure provides a method comprising the steps of obtaining an insert comprising a screen defining openings, each opening having a diameter of 10 microns to 200 microns; placing a volume of a fluid comprising a photopolymerizable composition and a contaminant in the insert; and subjecting the volume of the fluid to 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 of the photopolymerizable composition through the sieve of the insert, thereby providing a separated photopolymerizable composition. Systems are also provided that include an additive manufacturing apparatus, a centrifuge, and an insert configured to be inserted into the centrifuge. The methods and systems may advantageously help recover the contaminated photopolymerizable composition for reuse. 本公开提供了包括以下步骤的方法：获得包括筛的插入件，该筛限定开口，每个开口具有10微米至200微米的直径；将一定体积的包含光致聚合型组合物和污染物的流体置于该插入件中；以及使该体积的该流体经受离心力，以通过使该污染物保留在
