Disclosed is direct ink write (DIW) print extrusion head for 3D printing of viscous elastomers. The disclosed print extrusion head comprises a mixer assembly, comprising a fluid distribution cap coupled to a carrier, an in-line mixer coupled to the fluid distribution cap. A cooling jacket surrounds the in-line mixer. A nozzle is coupled to the in-line mixer and protrudes below the cooling jacket over a work surface. The position of the nozzle relative to the work surface is changeable. At least one heat source is on the chassis and disposed adjacent to the fluid distribution cap. The at least one heat source comprises a heat guiding element to direct heat to a region onto the work surface below the nozzle.

The present invention relates to a milk frother assembly which makes the two stirrers rotate forward and reverse respectively, by using the reversing drive mechanism, rotating rod one, rotating rod two, a carabiner and two stirrers, so as to achieve the advantage of more efficient milk frothing and controlling of the quality of milk bubbles. The assembly allows through its novel setting of the length adjustment mechanism, to manually slide the slide plate, then move the rotating rod two through the sleeve and the connecting rod, and then adjust the position of the inner stirrer head, which is suitable for making milk froth in various capacities.

The present set of embodiments relate to a system, method, and apparatus for culturing cells within a cell culture vessel having a mixing element. The cell culture system includes a flexible portion and a mixing element disposed therein. The mixing element includes a suspended foldable portion. The system is configured to reduce shear stress on cells without compromising mixing efficiency. This reduction is accomplished by using a mixing element having a large surface area allowing for reduced rotational speeds. The system is collapsible for ease of transport and disposal. The flexible portion collapses and the foldable portion folds to minimize the volume of the system while not in operation.
