A three-dimensional printed structure can include a photocurable resin, a sinterable material, and a plurality of elongated particles. The elongated particles are distributed within the printed structure. The elongated particles are shaped and distributed to promote porosity control (e.g., improved densification) within the structure.

The ceramic production and purification equipment of the present invention comprises a first fuselage, a furnace is fixedly arranged on the right end surface of the first fuselage, a cavity is provided in the first fuselage, and a top surface of the first fuselage is provided. A fixed block is fixedly fixed, and a feeding slot with an upward opening is provided in the fixed block. The device of the present invention can purify the ceramic before melting and casting. Compared with the traditional purification equipment, the device can remove iron impurities more thoroughly and the produced ceramics have higher purity. The equipment can also remove other impurities, while the operation is simple and clear, convenient and fast. In addition, the equipment can screen fine ceramic powder for melting, reducing the time required for melting ceramic powder, and the equipment has high purification efficiency.

A ceramic and a method of forming a ceramic including milling steel slag exhibiting a diameter of 5 mm of less to form powder, sieving the powder to retain the powder having a particle size in the range of 20 to 400 removing free iron from the powder with a magnet, heat treating the powder at a temperature in the range of 700 C. to 1200 C. for a time period in the range of 1 hour to 10 hours and oxidizing retained iron in the powder, compacting the powder at a compression pressure in the range of 20 MPa to 300 MPA, and sintering the powder at a temperature in the range of 700 C. to 1400 C. for a time period in the range of 0.5 hours to 4 hours to provide a ceramic.

The invention relates to a method for the production of solid surfaces for construction, in particular large boards made from completely inorganic components, for use as kitchen worktops, bathroom surfaces, building cladding materials, flooring and for other uses related to the field of construction. The invention is suitable for both indoor and outdoor environments.
