Abstract: The methods is provided for 3D-printing a polymeric scaffold which can have a large cross-sectional area, but can be porous, such that the printed portion of the scaffold has features with dimensions that allow rapid resin recoating without the mechanical assistance of a recoating blade. This 3D-printed scaffold can then be immersed in a polymeric precursor (e.g., comprising monomers and/or oligomers) that flows into and is retained in the scaffold. Excess polymeric precursor can be removed (e.g., washed) from the exterior of the scaffold. The entrained polymeric precursor can then be polymerized to create a polymeric object. The polymeric object can have a large cross-sectional area, a high bulk density, and other desirable properties. The other properties can be achieved by having two intertwined but not homogenously mixed polymers that each have their individual properties, but work to impart desirable properties on the polymeric object as a whole.

Abstract: Provided herein are systems and methods for forming a polymeric object. The systems and methods can use monomers having a first type of functional group that is capable of polymerizing upon exposure to radiation and a second type of functional group that is capable of polymerizing at a second condition. The monomers can be polymerized such that the polymeric object has a first and a second network of linkages.
