Abstract
Compositions containing curable recombinant human collagen, and kits comprising same, which are usable in preparing modeling material formulations for additive manufacturing (e.g., 3D bioprinting) of 3D objects are provided. Methods utilizing such modeling material formulations in additive manufacturing of 3D objects having a collagen-based material in at least a portion thereof, are also provided. The formulations feature a desired viscosity at a temperature higher than 10° C. (e.g., room temperature or 37° C.) and allow performing the additive manufacturing without cooling the system or a part thereof.
