Zusammenfassung:	The present disclosure provides printable compositions comprising: about 1 weight percent (wt %) to about 40 wt % of one or more hydrophilic monomers; a swelling control agent selected from a hydrophobic monomer, a short chain crosslinker, or a combination thereof; about 0.01 wt % to about 2 wt % of a photo initiator; and 0 wt % to about 75 wt % of a vehicle comprising a protic solvent, by weight of the printable composition. The disclosure also includes methods of use and manufacture related to printable compositions.
