Abstract
A printable composition for the manufacture of cell-receiving scaffolds comprising about 0.3 wt % to about 3.0 wt % of one or more collagens; about 5.0 wt % to about 40.0 wt % of one or more monomers; about 0.5 wt % to about 2.0 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; wherein the printable composition has a resolution of about 100 microns or less when printed, a photo speed (Dp/Ec) of about 0.1-5 mm (Dp) and about 10-100 mJ/cm2 (Ec) when printed, and a green strength of at least about 5 kPa after drying. The present technology further includes methods of manufacturing a three-dimensional cell-receiving scaffold using the printable composition.
