Abstract: Various methods and systems are provided for mixing and dispensing viscous materials for the creation of additive structures. As one example, during a mixing and dispensing operation with a mixing and dispensing head of a multi-dimensional printing apparatus, linear movement of a mixing rod positioned within a mixing chamber of the mixing and dispensing head, at least along a central axis of the mixing chamber, is adjusted based on an operating condition of the printing apparatus and dispensing of mixed liquids from the mixing and dispensing head is stopped by stopping one or more pumps fluidly coupled to the mixing chamber and linearly moving the mixing rod upward and away from a dispensing nozzle of the mixing and dispensing head.

Abstract: A copolyamide composition comprising a statistical copolyamide containing 70-99 wt % of diamine and dicarboxylic acid repeat units and 1-30 wt % of lactam or AA-BB repeat units, whereby incorporation of the comonomer lactam or AA-BB unit reduces the crystallization rate (longer crystallization times) while maintaining (1) high melting point, (2) low potential plate out, (3) low oxygen permeation, (4) high tensile strength and (5) puncture/tear resistance.

Abstract: Various methods and systems are provided for mixing and dispensing viscous materials for the creation of additive structures. As one example, during a mixing and dispensing operation of a multi-dimensional printing apparatus, one or more liquids may flow into a mixing chamber via one or more material inlets arranged in a wall of the mixing chamber below a high pressure bearing of a mixing rod positioned within the mixing chamber; and movement of a mixing rod positioned within the mixing chamber is adjusted based on an operating condition of the printing apparatus.

Abstract: Two part sole structures are provided having a first foam component containing a polyolefin resin with a polyurethane resin component adhered to a surface of the first foam component. For example, in some aspects, a sole structure or a portion thereof is provided having a first sole component containing a foam composition and a second sole component adhered to a surface of the first sole component, where the second sole component includes a polyurethane resin. The second sole component is in some aspects printed or extruded onto the surface of the foam. In particular, midsoles including the foams and having an outsole component on the ground facing portion are provided for use in an article of footwear. Methods of making the sole structures are provided, as well as methods of making an article of footwear including one of the sole structures.

Abstract: Various methods and systems are provided for mixing and dispensing viscous materials for the creation of additive structures. As one example, in a multi-dimensional printing apparatus, one or more materials flow into a mixing chamber via one or more corresponding inlet channels, a rotational speed of a mixing rod positioned within a mixing chamber is adjusted based on a volume of the mixing chamber and a flow rate of the one or more materials into the mixing chamber, the mixing rod including a set of straight cutaways extending along a length of a bottom portion of the mixing rod and forming flat side surfaces of the mixing rod; and a mixture of the one or more materials is dispensed from the mixing chamber via a dispensing nozzle of a mixing and dispensing head.
