Abstract: Embodiments relate generally to methods of manufacture of a filtration media, such as a personal protection equipment mask or respirator, which may incorporate a forcespinning process to form nanofibers. Some embodiments may comprise forcespinning material onto a convex mold, which may, for example, be in the shape of a human face. Other embodiments may comprise forcespinning material onto an inner and/or outer shell of a personal protective equipment mask, such as a flat fold mask. In an embodiment, the forcespun nanofibers may be functionalized, and therefore may, for example, be operable to capture one or more gases.

Abstract: Multi-material, three-dimensional fabrication is improved by the use of a purge wall adjacent to an object to absorb transitional artifacts of material changes. The structure of the purge wall may be selected to reduce build time, and to reduce certain printing artifacts such as warping and delaminating. For example, alternating layers of offset or mirrored zigzag patterns may be used to reduce and distribute the layer-to-layer adhesion surfaces throughout the purge wall while providing sufficient contact points to maintain the structural integrity of the purge wall.

Abstract: The technology provides for alignment of forming positions of glazing gaskets formed on both front and rear sides of a glass panel. After the glazing gasket has been formed on the multilayer glass panel, a first distance L1 is measured from the reference member to the glazing gasket. After the multilayer glass panel has been reversed and positioned at the reference position for the glass panel, a second distance L1′ is measured from the reference member to the glazing gasket. An offset amount of the forming position of the glazing gasket on the rear side of the multilayer glass panel is determined from the difference of the first distance L1 and the second distance L1′. An application starting position of the application nozzle when forming the glazing gasket on the rear side of the multilayer glass panel is corrected based on the offset amount.
