Abstract: The invention discloses a 3D printer based on liquid-solid chemical reaction deposition and operating methods thereof, comprising a sealed forming chamber, a powder container, a forming container, a powder spreading mechanism, and a three-axis linkage mechanism in the sealed forming chamber. The three-axis linkage mechanism moves a nozzle in the sealed forming chamber according to a movement path planning of a control system of the 3D printer. A liquid supply device is provided outside the sealed forming chamber. The liquid supply device contains a gel-like reactant. The nozzle is a liquid nozzle. The liquid nozzle communicates with the liquid supply device through a following conduit.
Abstract: An information processing device includes: a foldable one display; a memory which stores at least a program; and a processor. By executing the program stored in the memory, the processor performs display mode switching processing to switch among a first display mode to control display in such a manner that a screen area of the display is set as one display area, a second display mode to control display in such a manner that the screen area of the display is split into two display areas of a first display area and a second display area with the first display area set as a primary screen and the second display area set as a secondary screen, and a third display mode to control display in such a manner that the second display area is set as the primary screen and the first display area is set as the secondary screen.
Abstract: Provided is an active-energy-ray-curable composition including: a polymerizable monomer having static surface tension of 40 mN/m or greater at 25 degrees C., a content of the polymerizable monomer being 15% by mass or less relative to total amount of the active-energy-ray-curable composition; an organic pigment serving as a colorant, the organic pigment being contained in 2% by mass or greater relative to total amount of the active-energy-ray-curable composition; and a dispersant having amine value of 5 mgKOH/g or greater but 35 mgKOH/g or less, amine value being greater than acid value of the dispersant, the dispersant being contained in 15% by mass or greater but 70% by mass or less relative to mass of the organic pigment, wherein the active-energy-ray-curable composition is substantially free of a surfactant, and wherein a water content in the active-energy-ray-curable composition is 500 ppm by mass or greater but 3,000 ppm by mass or less.
Abstract: Waste product from any of a variety of processes (injection molding, selective laser sintering) is processed to form powders that have particle size and distribution optimal for a 3D printing technology known as Composite Based Additive Manufacturing (CBAM). Alternative recycling processes include grinding and sieving, emulsion extruding, and liquid-liquid phase separation.
