Impact Statement:
In this study, we report the development of a novel multimaterial segmented three-dimensional printing methodology to fabricate porous scaffolds containing discrete horizontal gradients of composition and porosity. This methodology is particularly beneficial to preparing porous scaffolds with intricate structures and graded compositions for the regeneration of complex tissues. The technique presented is compatible with many commercially available bioprinters commonly used in biofabrication, and can be adapted to better replicate the architectural and compositional requirements of individual tissues compared with traditional scaffold printing methods.

What is an Electrochemical Gradient?
The chemical gradient relies on differences in the abundance of a substance on the outside versus the inside of a cell and flows from areas of high to low ion concentration. In contrast, the electrical gradient revolves around an...

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
