Apparatuses and methods for removing support material from and/or smoothing surfaces of an additive-manufactured part are disclosed. Apparatuses may include a spraying chamber, a support surface within the spraying chamber, and one or more nozzles having the ability to spray a fluid at the additive-manufactured parts. The fluid may include a liquid and solid particles carried by the liquid. The support surface may have the ability to support the additive manufactured part. The apparatus may include a tank having the ability to hold at least some of the fluid. A heater may be included for heating the fluid to a desired temperature.

An example processing system for processing a part includes: a processing chamber to hold the part to be processed; a plurality of supply reservoir to contain respective processing fluids; an injection system fluidly coupled to the plurality of supply reservoirs; and a controller operatively coupled to the injection system, the controller to: based on the part to be processed, select a processing sequence for processing the part; and control the injection system to execute the selected processing sequence; wherein the processing sequence is selected from: (i) injecting, sequentially, a first volume of a first processing fluid and a second volume of a second processing fluid; and (ii) combining a third volume of a third processing fluid and a fourth volume of a fourth processing fluid to form a combined processing fluid and injecting the combined processing fluid into the processing chamber.

The present invention relates to pharmaceutical dosage forms, for example to a tamper resistant dosage form including an opioid analgesic, and processes of manufacture, uses, and methods of treatment thereof.

A method of and apparatus for fluffing a cleaning article. The cleaning article has a layer of tow fibers and a layer of sheet material, joined together in a layered construction. The apparatus and process spray a fluid blast onto the article, disrupting the tow fibers. The fluid may be air and causes different fibers to react so as to increase the volume of the cleaning article.

A reforming device (1) is provided with, on one end side of a chamber (2), a gas supply part (3) and, on the other end side of the chamber (2), a gas discharge part (4). A support part (5) for supporting a porous material (10) is provided between the gas supply part (3) and the gas discharge part (4) inside the chamber (4). Then, the unsaturated hydrocarbon gas of an unsaturated hydrocarbon supply device (31) and the ozone gas of an ozone generation device (32) are supplied into the chamber (2) via the gas supply part (3) so as to reform the outer-peripheral-side surface and the inner side surface of the porous material (10) accommodated inside the chamber (2). The gas inside the chamber (2) is sucked by the gas discharge part (4) and discharged to the outside of the chamber (2).

A method of cleaning residual resin from an additively manufactured object, includes: (a) enclosing an additively manufactured object in an inner chamber of a centrifugal separator, the additively manufactured object including a light polymerized resin with a surface coating of viscous, unpolymerized, residual resin; (b) flooding the chamber with a volatile organic solvent vapor without contacting liquid organic solvent to the object, the vapor present in an amount sufficient to reduce the viscosity of the residual resin; and (c) spinning the additively manufactured object in the chamber to centrifugally separate at least a first portion of the residual resin from the object.
