Abstract: A printer forms a three-dimensional object on a rotating substrate. The printer includes a first driver to rotate the substrate past at least one printhead at a predetermined velocity and a controller to operate the printhead to eject material onto the substrate to form the object. A second driver is operated to move the position of the printhead perpendicular to the substrate to maintain a predetermined gap between the printhead and the layer of material most distant from the substrate. The second driver is further operable to move the position of the printhead parallel to the substrate to adjust a resolution of the ejected material. The controller interpolates an alternating signal generated from a position encoder to adjust the operation of the printhead based on the rotational position and velocity of the substrate.

Abstract: Techniques are provided to independently control 3D shape and chemistry of rapidly produced colloids. A pre-polymer mixture including a monomer is made to flow into a channel with insular relief in a wall at a known location of the channel. A stimulus that polymerizes the pre-polymer mixture is directed onto the known location to form a structure locked in place at the known location by the insular relief. A pressure is applied to the channel that is sufficient to deflect the wall having the insular relief sufficiently to release a hydrogel particle comprising the structure.

Abstract: A method for the spinning of a fiber comprising cellulose nano-fibrils aligned along the main axis of the fiber from a lyotropic suspension of cellulose nano-fibrils, the nano-fibril alignment being achieved through extension of the extrude fiber from a die, spinneret or needle, wherein the fiber is dried under extension and the aligned nano-fibrils aggregate to form a continuous structure and wherein the suspension of nano-fibrils, which has a concentration of solids of at least 7% wt, is homogenized using at least a mechanical, distributive mixing process prior to its extrusion. The fibrils used in this method can be extracted from a cellulose-rich material such as wood. The invention also related to a cellulose-based fiber obtained according to this method and to a cellulose fiber which contains at least 90% wt of crystallized cellulose.

Abstract: A manufacturing device includes a feeder, a first pressing roller, a second pressing roller, a third pressing roller, a transmission assembly, and a driving assembly. The first pressing roller and the second pressing roller cooperatively press a hot melt adhesive from the feeder to obtain a preprocessed light guide plate.

The third pressing roller separates the preprocessed light guide plate from the second pressing roller to obtain a light guide plate. The transmission assembly connects the second pressing roller and the third pressing roller. The driving element is connected to the transmission assembly, and drives the transmission assembly to rotate the third pressing roller around the second pressing roller, and thus adjusting a contact area and a contact time between the light guide plate and the second pressing roller.
