  • Patent number: 11278083
    Abstract: The present invention relates to a midsole material composition, a method for producing the midsole material and a shoe sole. The midsole material composition comprises an elastomer, a thermoplastic polymer, a suitable crosslinker and a catalyst, such that the midsole material of the present invention can be fabricated by subjecting the midsole material composition to a phase-inversion crosslinking reaction and a foaming process. The aforementioned thermoplastic polymer, which is a recyclable material, is inverted into a continuous phase after the phase-inversion crosslinking reaction, thereby enhancing a recycling property of the midsole material and improving a reusability of the shoe sole.

  • Publication number: 20060290772
    Abstract: The invention discloses a method of manufacturing rapid prototyping workpiece by projecting a laser beam or other light onto the photo-conductive drum to attach powder materials to form a thin layer, and then coat the thin-layer material on a working platform. A point, line or plane light source of stronger intensity is used to go with the DMD (Digital Micromirror Device) or LCD (Liquid Crystal Display) to produce a physical change or a chemical change in the selected projecting region and combine the materials to become an acceptable property. The method comprises three stages of a process and repeats the process to complete a physical workpiece. The first stage refers to evenly spreading electric charges on a photo-conductive drum, and then projects a laser beam or a visible light onto the photo-conductive drum to electically conduct the electric charges and lower the electric potiential.

  • Publication number: 20050225007
    Abstract: This invention applies a new computer and printer integrated technology to aid forming physical objects rapidly, and the method and apparatus are disclosed to satisfy the market requirements for a quick, reliable, safe, and inexpensive operation. The invention coverts a virtual object stored in the storage device of computer through software that slices the virtual object into many layers. The cross-section of the first layer is sent to a printer or a plotter, and the contour domain is printed or plotted by the printer or plotter. The fluid (not limited to binder) in the printer head is coated onto a layer of uniform distributed porous material which allows the powder and fluid to combine with each other; however, the combining process can be either a natural or an artificial process to enhance the binding force between the fluid and powder. After the first layer is finished, the second layer of powder is uniformly distributed on the first layer, and the contour printing process is repeated.
