The present disclosure relates to printing apparatus and manufacturing techniques for the manufacture and fabrication of pressure suits and space suits. The disclosure also relates to space suit components formed from additive polymer, and components including one or more layers of a mesh fabric with an applied layer of an additive polymer. One method includes providing an apparatus comprised of a six-degree of freedom motion manipulator with the motion manipulator attached to one or more printing extruder heads. Additive polymers may be extruded via the one or more printing extruder heads to form 3D printed space suit components.

A polymer film comprising polyvinyl acetal and a laminated glass manufactured using the same are provided. At least one surface of the polymer film has a void volume (Vv) value at a material ratio of 10% ranging from 2 μm.sup.3/μm.sup.2 to 18 μm.sup.3/μm.sup.2, wherein the void volume (Vv) and material ratio are defined in accordance with ISO 25178-2:2012.

Provided is a conductive polymer dispersion, including: a conductive composite containing a π-conjugated conductive polymer and a polyanion; a vinyl versatate polymer; and a dispersion medium.

The present disclosure relates to a tool used to producing anatomical phantoms. The tool includes an inner flexible mold which sits inside a rigid, thermally conductive outer shell. The rigid shell may be made out of aluminum. The silicone mold and thermally conductive shell both include at least two interlocking components. The shell is held together by a locking mechanism which can expand upon internal pressure. An anatomical phantom is produced from polyvinyl alcohol hydrogel by freezing and thawing a PVA liquid precursor in the silicone mold and demolding it.

There is provided an interlayer film for a laminated glass having improved appearance which has a MD and TD direction; and one end, and another end being opposite side of and thicker than the one end. The one end and other end are positioned on both sides of the interlayer film in the TD direction. When the distance between the one end and other end is X, the absolute value for the difference between the largest and smallest thermal shrinkage ratios from among three thermal shrinkage ratios is 15% or less. The three thermal shrinkage ratios are positioned from the one end towards the other end in MD direction with a first thermal shrinkage ratio at 150 C. at a first position at 0.05X, a second thermal shrinkage ratio at 150 C. at a second position at 0.5X, and a third thermal shrinkage ratio at 150 C. at a third position at 0.95X.

A preform coating device is provided with: a rotational holding part that horizontally holds a preform and rotates the preform about the axis of the preform, and that grasps a spout of the preform; a conveyance part that conveys the preform by moving the rotational holding part; a dispenser that discharges a coating liquid toward the preform; a preform support part that supports the bottom-side end of the cylindrical barrel of the preform while the dispenser is discharging the coating liquid; and a spout support part that supports the outer circumferential surface of the spout of the preform while the dispenser is discharging the coating liquid.

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.

A system and method for creating a rigid foam substitute is provided. By using natural binding materials and natural fiber materials, the system and method may be used to create environmentally friendly substitutes for expanded polystyrene. The system generally comprises a processing room and molding facility. The processing room may comprise an opener, cleaner, and blower, which may be used to break up and clean the natural fiber material. The molding facility may comprise a mixer, molder, and kiln, which may be used to create casts. The method generally entails processing a natural fiber material before mixing it with a natural binding material and fluid to create a fluidic mixture, wherein said fluidic mixture is subsequently molded and cured to create a finished product.

A coated filament for use in additive manufacturing includes a base polymer layer formed of a base polymer material and a coating polymer layer formed of a coating polymer material. At least the coating polymer material is susceptible to dielectric heating in response to electromagnetic radiation, thereby promoting fusion between adjacent beads of coated filament that are deposited during the additive manufacturing process. Specifically, when electromagnetic radiation is applied to an interface area between two adjacent beads of the coated filament, the polymer coating layer melts to diffuse across the interface area, thereby preventing formation of voids. The base polymer material and the coating polymer material of the coated filament also may have similar melting points and compatible solubility parameters to further promote fusion between beads.

Plasiticized polyvinylacetal films with greater film-to-film uniformity are produced by a process of extruding a melt stream containing a polyvinyl acetal and a plasticizer at 150-250 C., the film having a predefined melt viscosity at 60-170 C., by providing a first melt stream of at least a first plasticizer and a first polyvinyl acetal resin and measuring its melt viscosity at 60-170 C. online; and adjusting the 60-170 C. melt viscosity by adding a second plasticizer and/or a second polyvinyl acetal resin to the first melt stream in an amount to provide a second melt stream with a melt viscosity at 60-170 C. having a difference of at most 20% to the predefined melt viscosity at 60-170 C.
