摘要： A invention disclosed a bio-mimicked three-dimensional laminated structure at least comprising a flexible lattice structure, which is characterized in that the flexible lattice structure comprises a plurality of particle units are uniformly disposed and evenly distributed in the X-axis, the Y-axis, and the Z-axis direction and evenly distributed as a lattice matrix of an array grid in an identical plane; wherein each of the particle units is an opened hollow shell or a close shell. The design eliminates the need for support structures and the subsequent post-processing required to remove them. A shell-shaped close cell bio-mimicked three-dimensional laminated structure bio-mimicking a sea urchin shape was introduced for the load-bearing structure application.

摘要： An optical device for measuring a distance includes a prism, a beam splitter, a detector and a light source. The prism has a first light-incident surface and a plurality of first light-transmitting surfaces. The first light-incident surface is opposite to the first light-transmitting surfaces. The first light-transmitting surfaces intersect at a vertex. The beam splitter has a light-passing surface, a second light-incident surface and a second light-transmitting surface. The second light-incident surface faces the first light-transmitting surfaces. The light-passing surface is opposite to the second light-incident surface. The beam splitter includes a partially mirror surface facing the light-passing surface and the second light-incident surface. The light-passing surface faces a grating. The detector corresponds to the second light-transmitting surface. The light source emits a light beam to the first light-incident surface.

摘要： A photocurable resin composition for three-dimensional printing which is visible-light curable is provided, comprising a photosensitive prepolymer in a range of 76.5 wt % to 96.8 wt %, a photoinitiator in a range of 0.01 wt % to 5 wt %, an auxiliary photoinitiator in a range of 0.01 wt % to 15 wt %, and a solvent in a range of 0.01 to 10 wt %. A three-dimensional printing system comprises: an accommodation unit, a lifting unit, a formation unit, and a control unit. The accommodation unit is for accommodating a printing material. The formation unit, which is connected to the lifting unit, can be driven by the lifting unit so as to move with respect to a light emission unit. The control unit, coupled to the lifting unit, controls motion of the lifting unit. The light emission unit may be a mobile electronic device, a display device, or a digital television.

摘要： A large area deposition type additive manufacturing equipment is disclosed. The large area deposition type additive manufacturing equipment includes a light source module, a dynamic photomask module, a raw material tank and a deposition module. The light source module includes a plurality of light emitting members, a light diffusion member, a light enhancement member and a light emitting angle limiter. Light emitted from the light emitting members passes through the light diffusion member, the light enhancement member and the light emitting angle limiter to become a collimated curing light. The collimated curing light travels through a transparent member of the raw material tank and a dynamic photomask module to reach liquid photocurable material in the raw material tank, thereby curing the liquid photocurable material. The angle of emitted light ranges within ±30° with respect to a normal line of an incident plane of the light source module.
