To more efficiently manufacture a three-dimensional object shaped by layering a shaping material with a three-dimensional printer. A manufacturing method for a three-dimensional object according to an embodiment includes: a first shaping process (step S) of layering a shaping material with a three-dimensional object shaping device (three-dimensional printer) to shape a first shaping portion including a recess opened in a layering direction of the shaping material; a closing process (step S) of closing an open end of the recess of the first shaping portion; and a second shaping process (step S) of layering the shaping material with the three-dimensional object shaping device (three-dimensional printer) on the first shaping portion, which open end of the recess is closed, to shape a second shaping portion.

Manufacturing method for three-dimensional object

To provide a fuel cell which has a reaction layer having good reaction efficiency and an electron collection layer to efficiently collect electrons generated at the reaction layer and of which the output density is high and the characteristic is good and a method of manufacturing thereof, a fuel cell includes a first substrate provided with a gas flow path to supply a first reaction gas; a first electron collection layer formed on the first substrate; a first reaction layer formed on the first electron collection layer; an electrolyte film formed on the first reaction layer; a second reaction layer formed on the electrolyte film; a second electron collection layer formed on the second reaction layer; and a second substrate provided with a second gas flow path to supply a second reaction gas, the fuel cell including at least one of the first electron collection layer and the second electron collection layer being constructed by stacking conductive material particles. A method of manufacturing the fuel cell includes the first and/or the second electron collection layer formed by applying material to form the electron collection layer at predetermined intervals using a discharging device.

A first gas flow path is formed in a first substrate. The first substrate is processed in an ejection device to form a first collector layer, a first gas diffusion layer, a first reactive layer, and an electrolyte membrane. Similarly, the first substrate is processed to form a second reactive layer, a gas diffusion layer, and a second collector layer. A second substrate which has been processed to form a second gas flow path is then disposed on the first substrate to complete production of a fuel cell having a gas flow path formed therein the opening width of which is smaller than the particle diameter of the material constituting the gas diffusion layer.

Fuel cell and process for the production thereof

A titanium dioxide slurry for ink jet ink, which comprises water and surface-treated titanium dioxide particles dispersed in the water, the surface treatment being a treatment with an inorganic phosphoric acid compound. Also disclosed is an ink comprising the titanium dioxide slurry.

Ink jet white ink and titanium dioxide slurry therefor

A soft alumite is produced by forming an oxide film on the surface of an aluminum substrate. Printing is performed on a porous layer formed on the surface of the soft alumite while heating the soft alumite. Alternatively, printing is performed with a dye-based ink on a porous layer formed on the surface of the soft alumite.
