[EN] Disclosed is a method of manufacturing a waveguide device (1) comprising the following steps: additive manufacturing of a core (3) provided with an opening (2); additive manufacturing of at least one portion of an anode (5) through the opening; immersion of the core in a metal ion bath; electrodeposition of a conductive metal layer (4) on the walls (7) of the opening, by applying an electric current between the anode and a cathode.

[EN] The invention relates to a porous structure (21) made of ceramic that is intended to form the reinforcement of a part made of ceramic matrix composite material, the structure having a connected porosity defined by an internal surface (25) which comprises a plurality of first points (A1, A2), each first point being associated with a second point (B1, B2) that is aligned with this first point along a normal (N1, N2) to the internal surface taken at the first point, the structure being dividable into a plurality of elementary volumes (20) that are smaller than or equal to 5 mm3, in each of which: a characteristic pore length, corresponding to the maximum of the distance (L1, L2) separating each first point (A1, A2) from its associated second point (B1, B2), is less than or equal to 0.5 mm; and a porosity rate is greater than or equal to 50 percent. The invention also relates to a method for manufacturing such a structure and a method for manufacturing a part made of CMC material.

[EN] This optical shaping device (10) is provided with: a resin tank (18); a resin supply part (20) that is provided to one end section (40) of the resin tank (18) and supplies a liquid photocurable resin (12) to the resin tank (18); and a resin discharge part (22) that is provided to the other end section (42) of the resin tank (18) and discharges the photocurable resin (12) to the resin tank (18). While a shaped object (14) is formed by irradiation of at least the liquid photocurable resin (12) with laser light beam (38) or a light flux (72), the resin tank (18) causes the photocurable resin (12) to flow from the one end section (40) toward the other end section (42).

[EN] A method of printing a porous and/or non-porous three-dimensional structure is disclosed herein. The method includes providing an ink composition including a polymer dissolved in a solvent, dispensing the ink composition into a non-solvent at a temperature ranging from 20 degrees centigrade to 30 degrees centigrade, wherein the non-solvent renders precipitation of the ink composition to form the porous and/or non-porous three-dimensional structure in the non-solvent, and removing the non-solvent from the porous and/or non-porous three-dimensional structure. Disclosed herein includes a system operable to print a porous and/or non-porous three-dimensional structure, the system includes a syringe operable to dispense an ink composition into a non-solvent at a temperature ranging from 20 degrees centigrade to 30 degrees centigrade, wherein the ink composition includes a polymer dissolved in a solvent, and a motion control module which controls vertical and horizontal positioning of the syringe.
