The present invention generally relates to the printing of materials, using 3-dimensional printing and other printing techniques, including the use of one or more mixing nozzles, and/or multi-axis control over the translation and/or rotation of the print head or the substrate onto which materials are printed. In some embodiments, a material may be prepared by extruding material through print head comprising a nozzle, such as a microfluidic printing nozzle, which may be used to mix materials within the nozzle and direct the resulting product onto a substrate. The print head and/or the substrate may be configured to be translated and/or rotated, for example, using a computer or other controller, in order to control the deposition of material onto the substrate.

To provide a method for manufacturing a three-dimensional shaped object in which a three-dimensional shaped object is manufactured by discharging a shaping material from a discharge unit toward a stage to stack a layer, the method for manufacturing a three-dimensional shaped object includes: a first step of generating path data having a plurality of partial paths through which the discharge unit moves while discharging the shaping material; a second step of determining a line width of the shaping material in each of the partial paths and generating line width information for implementing the line width; a third step of generating shaping data including the path data and the line width information; and a fourth step of shaping the three-dimensional shaped object according to the shaping data. In the second step, the line width in a target path that is one of the partial paths is determined in accordance with a distance between a first wall and a second wall separated by the target path. The first wall and the second wall are side edges of the shaping material discharged in the partial path generated before the target path or a contour line of the three-dimensional shaped object.

A slicer in a material drop ejecting three-dimensional (3D) object printer generates machine ready instructions that operate components of a printer, such as actuators and an ejector having at least one nozzle, to form features of an object more precisely than previously known. The instructions generated by the slicer control the actuators to move the ejector and a platform on which the object is formed relative to one another at a constant velocity to form edges of the feature.
