A method for treatment of elements obtained by an additive manufacturing process comprises applying on the element a treating agent in liquid or gaseous form.

Methods comprise generating an electric field; encompassing fibers within the electric to orient the fibers in a desired orientation relative to each other; and subsequent to the encompassing, fixing the fibers in the desired orientation within a matrix material to at least partially create a composite part.

The present disclose provides methods for forming a microfluidic device. Methods for forming a microfluidic device may comprise providing a microfluidic structure and a film, treating a surface of the microfluidic structure, a surface of the film, or both with a solvent, subsequently pressing the microfluidic structure together with the film under a first heating condition to form the microfluidic device comprising the solvent, and applying a negative pressure to the microfluidic device under a second heating condition, which negative pressure is applied for a time period greater than 30 minutes or at a pressure less than 20 kilopascals (kPa) to remove at least a portion of the solvent. In some aspects, the present disclosure provides devices consistent with the methods herein.

The invention relates to a polymerization and post-tempering device (10) for tempering, in particular post-tempering, dental restoration parts (54) made of polymerizable plastics. At least one light source (38) which emits light in the visible and/or ultraviolet wavelength range and a light chamber with a door (14) to the light chamber are provided. The door (14) comprises a window (20) with a window pane (22) which consists of at least two layers (56, 58) whose layer facing the light chamber reflects at least 90%, in particular approximately 95%, of light, and whose layer facing away from the light chamber filters out UV light and/or blue light.

The present invention provides apparatus for post-processing an additively manufactured polymer part, comprising a reservoir (402) for containing a liquid solvent; a processing chamber (408) in controllable fluid communication with the reservoir; and a controller (418) configured to controllably post-process an additively manufactured polymer part located in the processing chamber by the solvent responsive to at least one parameter associated with the part. A method for post-processing an additively manufactured polymer part is also provided.

The invention relates to a method for treating a surface of a molded part produced according to a 3D printing method using a plastics material, wherein a solvent selected from the group consisting of halogen-free and non-polar hydrocarbons and derivatives thereof and/or a solvent selected from the group consisting of bio-based solvents is applied to the surface of the molded part. The invention also relates to a device for treating a surface according to the method according to the invention.

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.

Container assembly comprising a container and a closure, wherein the container is made of a crystallisable polymer material and comprises a neck portion with an outer cap surface and defines an outlet opening, the neck portion being configured for receiving the closure, wherein the closure includes a closure cap made of a crystallisable polymer material and has an inner cap surface, the closure cap being matched to the neck portion of the container to cover the outlet opening in a closed state, wherein the inner cap surface of the closure cap contacts the outer cap surface of the neck portion when the container assembly is closed, and wherein the material of the inner cap surface of the closure cap and/or of the outer cap surface of the neck portion is crystallised, to allow the container assembly to be opened after being closed for an elongated period of time.

An apparatus (200) for smoothing a surface of an object (100). The apparatus includes a chamber (210), a reservoir (324) configured to hold a liquid (322), and a nebulizer assembly (212) configured to generate a mist (104) from the liquid into the chamber. The nebulizer assembly includes a mesh (732), a vibrating element (731), and a wick (736). The object is received in the chamber and the mist is configured to surround the object.

A method for manufacturing a tableware article having a thermal-transfer printed pattern includes the following steps. Firstly, a PET resin composition including 3 to 15% by weight of an inorganic filler is provided. Next, the PET resin composition is granulated to obtain plastic granules. Then, the plastic granules are molded into the tableware article and the tableware article is post-crystallized. Finally, a thermal transfer printed pattern is printed on a surface of the post-crystallized tableware article.
