  • Patent number: 10647068
    Abstract: A composite material molding method is provided for forming a composite material. The molding includes disposing a reinforcing base material in a cavity inside an openable and closable mold, injecting resin into the cavity in a state in which a clamping pressure is exerted on the mold and curing the resin. When injecting the resin into the cavity, the injection pressure of the resin is adjusted between a first pressure that is higher than the clamping pressure and a second pressure that is lower than the clamping pressure, and the injection pressure of the resin is lowered from the pressure that is higher than the clamping pressure to the pressure that is lower than the clamping pressure at least once. The resin is thereby injected such that the pressure inside the cavity does not exceed the clamping pressure from the start of injection to the end of injection of the resin.

A translation stage may be positioned relative to a vat that is suitable for solidifying the highest un-solidified layer of the three-dimensional object directly beneath any existing, solidified layers of the three-dimensional object. A mask image projection system may project a two-dimensional image of the highest un-solidified layer through a transparent bottom of the vat and into the liquid resin. This may cause at least a portion of the liquid resin to solidify in the shape of the two-dimensional image and to adhere to the bottom of a surface beneath the solidified layer.

    Abstract: Systems, methods and computer program products are disclosed that facilitate measuring the light output of an additive manufacturing device light source without utilizing additional equipment, such as a light meter. Once the light source output has been measured, such information can be utilized for a variety of purposes, including, but not limited to: (i) delivering a uniform amount of light energy over time to each portion of a layer being formed; (ii) adjusting the intensity of each controllable element (e.g., pixel) of the light source to the measured minimum, thereby creating a uniformly intense light source; and (iii) minimizing the build time of layers or portions of a layer being formed based on the maximum intensity available within a given area of the build area.

    Abstract: An imprint apparatus for forming a pattern on a substrate by contacting an imprint material on the substrate with a mold includes a mold holding member configured to hold the mold and a mold deforming mechanism for applying a force to a side surface of the mold in a direction along a pattern face of the mold in which the pattern is formed in order to deform the pattern formed in the mold held by the mold holding member. The mold deforming mechanism includes a contact portion to contact with the side surface of the mold to press against the side surface. The contact portion is shaped such that a dimension of part of the contact portion to contact with the side surface of the mold is less than a dimension of part of the contact portion away from the side surface of the mold.

  • Patent number: 9022767
    Abstract: An injection molding machine is provided with an automatic mold thickness adjusting apparatus. The amount of compensation of the position of a rear platen that is adjusted at the time of installation of a mold is determined by calculating the thermal expansion of the mold that is expected to occur at the completion of a rise in temperature based on the difference in temperature between the mold temperature at the time of mold thickness adjustment and the mold temperature at the time of injection molding. Then, the rear platen is moved to the compensated position thus determined.

  • Publication number: 20150118343
    Abstract: An injection compression molding system includes a mold having a fixed first half and a displaceable second half. The second half is initially positioned with a cavity between the mold halves having a first clearance sized to receive a molten material puddle shot injected by an injection molding device without the puddle shot filling the cavity. A displacement device acts during or immediately after puddle shot injection, displacing the second mold half toward the first mold half creating a second clearance less than the first clearance. The second clearance defines a finished part thickness whereby displacement of the second mold half to the second clearance compresses the puddle shot so that the puddle shot fills the cavity and forms a finished part between the mold halves. Total time to inject and compress the puddle shot is less than or equal to 1.0 seconds.

  • Publication number: 20150028506
    Abstract: Arrangement information regarding shot areas is obtained in an imprinting method. When a pattern is sequentially formed in the shot areas, the attraction force of a first attraction area is reduced to less than that of the second attraction area. After the pattern is formed in the shot area corresponding to the first attraction area, the attraction forces of the first and second attraction areas are changed. The position information regarding the shot area corresponding to the second attraction area is obtained, which is compared with the position information regarding the shot area corresponding to the second attraction area based on the arrangement information. If the difference between the compared position information is a threshold value or less, positioning of a substrate and a mold is achieved using the arrangement information. If the difference is greater than the threshold value, the arrangement information regarding the shot areas is obtained again.
