Definitions

  • light irradiation means for irradiating light to an arbitrary position on the surface of the photocurable liquid
  • sedimentation means for sedimenting a layer cured by light irradiation, and scanning over the sedimented cured layer
  • a recoater for coating the upper surface of the hardened layer with the uncured liquid, wherein the recoater is separated from the upper surface of the hardened layer by a distance that allows the uncured liquid to be sucked into a gap formed between the upper surface of the hardened layer and the recoater.
  • a gap is formed between the lower surface of the recoater and the upper surface of the hardened layer, and the gap is sufficiently narrow so that the uncured liquid enters the gap due to its surface tension. Inhaled.
  • the term “inhalation” here means that the uncured liquid enters the gap between the lower surface A of the collector and the upper surface B of the hardened layer by a phenomenon similar to the capillary phenomenon as shown in (B) to (D) in Fig. 1. (C 1—C 2 ⁇ C 3 penetrates). Therefore, according to the above-described apparatus and method, the upper surface B of the hardened layer The uncured liquid is introduced smoothly. In addition, at this time, as shown in Fig.
  • the first needle gauge 62 is attached to the upper plate 42 via a bracket 64.
  • the first needle gauge 62 is composed of a needle part 62 a, a rectangular cross-section part 62 b, and a square cross-section part 62 c from below.
  • a hole 64b having a rectangular section is formed to receive the rectangular section 62b.
  • the needle 62a hangs down as shown in FIG.
  • the needle 62a is lifted upward. This state is the evacuation state.
  • the lower surface 44b of the lower plate 44 is adjusted to a position slightly higher than the liquid level.
  • Side edges 44c are attached to both sides of the lower surface 44 of the lower plate 44, and the lower surface of the side edge 44c is adjusted to a height at which the side edge slightly enters the liquid.
  • the inhalation phenomenon described with reference to Fig. 10 starts from the side edge 44c, and the photocurable liquid is adsorbed within the intervals indicated by G in Figs. 13 and 16.
  • the running portion of the side edge 44c is not irradiated with light, and the hardened layer does not interfere with the side edge 44c.
