Abstract: A method of printing a hydrogel scaffold is provided which includes providing a container containing an ink and a liquid that is immiscible with the ink; applying light from a light source to the ink to form a portion of the hydrogel scaffold; and applying light from a light source one or more additional times to produce one or more additional portions of the hydrogel scaffold.

Abstract: An additive manufacturing device includes an output device and a controller. The output device is configured to receive at least one material to generate a component. The controller includes one or more processors configured to receive a model including a plurality of pixels representing the component, identify at least one pixel of the plurality of pixels corresponding to a first surface of the component, modify the model to adjust an exposure corresponding to the at least one pixel based on a target exposure, and control operation of the output device to cause the output device to generate the component based on the modified model.

Abstract: Non-spherical particles including a major dimension, for example flakes of material, are positioned with the major dimension oriented generally along an article surface in respect to which the particle is disposed. The particles, disposed in a fluid medium, the viscosity of which can be increased to secure the particles in position, are positioned using a force from flow of the fluid medium on the particles.
