Selective irradiation method to induce linear or radial gradients on a photosensitive substrate. Ultraviolet (UV) irradiation is selectively filtered by a mask, which is either completely opaque (a) or has a designed distribution of opacity (b). The movement of the mask or the selective irradiation induces a controlled modification of the substrate, which results in a physical or chemical gradient. Gradients present in structures today help us understand more about their properties, and this is critical in areas like bioprinting. Through replicating gradients we can begin to make accurate high resolution parts and scaffolds. Researchers explored these needs further in a recently published paper, ‘ Engineering Biological Gradients .’ Tissue engineering is growing more and more of interest to researchers around the world as they continue to strive to 3D print human organs—a subject we have followed many times over the years as progress has been made in 3D […]
