A bladeless mixer for mixing a liquid, includes a cylindrical or truncated cone-shaped receptacle having an axis A and a radius R, the radius R being the shortest distance between the axis A and a side wall of the receptacle, the liquid to be mixed being placed in the receptacle and having an exposed surface at a height H measured along axis A; a member for tilting the receptacle such that axis A forms a non-zero-degree angle of up to 30° relative to the vertical direction; a member for imparting a rotational movement to the receptacle along axis A at an angular speed of rotation Ω; wherein the aspect ratio H/R of the height H to the radius R and the angular speed of rotation Ω are selected such that an inherent mode of inertia of the liquid has an unstable resonance when the receptacle is tilted and rotates.

Method and apparatus to agitate a liquid are disclosed herein. An example apparatus includes a carrier having a base that includes a ridge extending from the base and a collar extending from the base. The example apparatus also includes a container supported on the base, the container movable between (A) a locked positon in which the ridge fixedly engages the container to non-rotatably couple the container to the base and (B) an unlocked position in which the container is disengaged from the ridge and the container is rotatable about the collar.

Mixing devices and associated methods are described herein. Various embodiments of mixing devices can comprise a plate configured to rotate about a longitudinal axis and a plurality of enclosures coupled to the plate. The enclosures can each include (a) at least one sidewall that defines an oblique angle with the plate and (b) a chamber configured to receive a media and a fluid. The enclosures can be fluidly coupled to a fluid source for receiving the fluid in the chambers. When the plate is rotated, the enclosures revolve about the longitudinal axis to mix the media with the fluid in the chambers.

In one example, a build material supply system for additive manufacturing includes a mixer to aperiodically rotate a non-circular mixing chamber containing powdered build material to form mixed powdered build material.

Mixing devices and associated methods are described herein. A mixing device configured in accordance with embodiments of the present technology can include, for example, a plate configured to rotate about a longitudinal axis and a plurality of enclosures coupled to the plate. The enclosures can each include (a) at least one sidewall that defines an oblique angle with the plate and (b) a chamber configured to receive a media and a fluid. The enclosures can be fluidly coupled to a fluid source for receiving the fluid in the chambers.
