Coated tubular construct for biological and industrial applications and method of making a tubular construct

A coated tubular construct for biological and industrial applications includes a plurality of channels, where each channel is radially surrounded by a wall comprising a first polymer, and a conformal coating comprising a second polymer is disposed on an outer and/or an inner surface of each wall. A method of producing a tubular construct includes 3D printing a template structure comprising a sacrificial material and a photoinitiator, and immersing the template structure in a first prepolymer solution comprising a first prepolymer and a co-initiator. During the immersion, the template structure is exposed to light, and the first prepolymer undergoes radical polymerization to conformally coat the template structure with the first polymer, forming a coated template. The sacrificial material is removed from the coated template, and a tubular construct comprising the first polymer is formed.
