A dispenser for additive material manufacturing having a sealed cartridge with sterile material to be dispensed. The cartridge is removable from a support housing that is movable during deposition of additive material. A nozzle extending from a heated plenum below the cartridge is inserted into a sealed variable volume enclosure supporting the article being manufactured on a movable table within the enclosure.

A fabrication method of an elastomer breath structure includes the steps of applying a liquid elastomer onto a substrate an initial curing of the liquid elastomer on the substrate partially into a partially cured polymer, condensation of water droplets from the environment onto the partially cured polymer, and finishing curing of the partially cured polymer with parallel removal of the water droplets creating surface dimples on the cured elastomer.

The invention relates to a method for supplying a polymerizable mixture to at least one molding device, said method comprising the following steps: a) providing a tank containing the polymerizable mixture (box E1), b) reaching a set value of pressure (Ps) in the tank, smaller than the ambient pressure (box E2), c) continuously maintaining the pressure (P) in the tank at the set value of pressure while supplying the polymerizable mixture to the molding device (boxes E3, E4, E41, E42, E5, E51). The invention also relates to a supply device for supplying the molding device with polymerizable mixture.

Expanded, nanofiber structures are provided as well as methods of use thereof and methods of making.

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.

This disclosure relates to a method for reducing gas bubble entrapment from bulk cured room temperature condensation curable silicone compositions. The method comprising applying a predefined volume of a bulk cured room temperature condensation curable silicone composition bulk curable silicone composition onto or into a target substrate. The method further comprising at least initially curing the composition in an atmosphere having a relative humidity of X %, wherein X has a value in the range of 0<X?40%, for a predetermined time or until no gas bubbles remain visible in the composition.

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.

A dispenser for additive material manufacturing having a sealed cartridge with sterile material to be dispensed. The cartridge is removable from a support housing that is movable during deposition of additive material. A nozzle extending from a heated plenum below the cartridge is inserted into a sealed variable volume enclosure supporting the article being manufactured on a movable table within the enclosure.

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.

A bioprinting system comprises: a) a printing module containing at least one printhead for printing transferable objects of biological interest and at least one target, b) a feed source for the printhead for printing objects of biological interest, c) an activation means for the transfer of the objects of biological interest to the target, d) a means for relative displacement of the printhead with respect to the target, e) a sterilizable sealed enclosure, characterized in that the printing module is placed the sterilizable sealed enclosure the activation means is located outside of the sterilizable sealed enclosure, and the sterilizable sealed enclosure has a leaktight interaction zone with the activation means.
