Sputtering printheads, additive manufacturing systems comprising the same, and methods for additive manufacturing are provided. Sputtering printheads of the present invention use a plasma to sputter a feedstock material which is directed towards a target. A printhead can include a heater to heat the feedstock to, or near, the material's melting point as it is being sputtered to increase the deposition rate. A convergent nozzle can also increase the deposition rate. Printheads of the present invention are readily reconfigurable such that the same printhead can be used to deposit different materials, such as metals and non-metals, in succession by replacing the feedstock material and making changes to a few settings. Additive manufacturing systems of the present invention can be operated at normal room temperatures and pressure.

The invention relates to a method for preparing waste powder from generative production processes, by means of which three-dimensional objects are produced in layers from a powdery base material. The aim of the invention is to provide a method for the combined mechanical and material preparation of waste powder, wherein the waste powder is brought into such a structure that subsequently, by mixing with or even without new powder or mixtures of new and waste powders, a high-quality powdery material becomes available for generative production processes. This aim is achieved in that the waste powder is subjected to a mechanical treatment by reducing the waste powder to small pieces with a grinding mill.

A production method for a resin molding includes: preparing fiber-reinforced resin by continuously feeding a long roving containing a reinforcing fiber, with its length unchanged, into base resin that has been heated to be plasticized; forming a resin molding using the fiber-reinforced resin; and heating the formed resin molding in a non-oxidizing atmosphere.

A system and method for enclosing the blowing area of a biopolymer blown film production process. The enclosure surrounds the blown film tower and includes at least a climate controller to maintain an optimal temperature for the blown film process.

The present disclosure relates to a container for receiving and supporting extruded biological material during a bioprinting process. The container comprises a reservoir configured to receive a suspension medium, a plurality of walls at least partially defining the reservoir, and a self-scaling port disposed in one or more of the plurality of walls.

An apparatus for shaping plastic preforms into plastic containers is disclosed. Said apparatus comprises a conveying device on which a plurality of blowing stations are arranged. Each of said blowing stations encompasses a blow mold, within which a plastic preform can be shaped into a plastic container. The apparatus further comprises a clean chamber, within which the plastic preforms can be conveyed. According to the invention, the zone of the conveying device in which the blowing stations are arranged is located in the clean chamber, and at least one additional zone of the conveying device is located outside the clean chamber.

A method for etching a layer of assembled block copolymer including first and second polymer phases, the etching method including a first step of etching by a first plasma formed from carbon monoxide or a first gas mixture including a fluorocarbon gas and a depolymerising gas, the first etching step being carried out so as to partially etch the first polymer phase and to deposit a carbon layer on the second polymer phase, and a second step of etching by a second plasma formed from a second gas mixture including a depolymerising gas and a gas selected among the carbon oxides and the fluorocarbon gases, the second etching step being carried out so as to etch the first polymer phase and the carbon layer on the second polymer phase.

Provided is a method of producing a cured product pattern, including: a first step (arranging step) of arranging a layer formed of a curable composition (1) that is the components of the curable composition (1) except the component (D) serving as a solvent on a substrate; and a second step (applying step) of applying droplets of a curable composition (2) discretely onto the layer formed of the curable composition (1), the curable composition (1) having a number concentration of particles each having a particle diameter of 0.07 m or more of less than 2,021 particles/mL, and the curable composition (1) having a surface tension larger than that of the curable composition (2).

The present application relates generally to tubes, such as thin walled catheter liners with small wall thicknesses (e.g., less than 1 mm), including crosslinked fluoropolymers, e.g., crosslinked poly(tetrafluoroethylene). The disclosure further provides methods of manufacturing such tubes and systems for manufacturing such tubes.

Methods, systems and apparatuses are disclosed for making and post-processing a 3-D printed object for laminate-forming tooling, and components made using post-processed 3-D printed laminate-forming tooling.
