In a manufacturing method for manufacturing a dispersion body, a plurality of types of solid particles, water, and a liquid other than water are mixed. The solid particles and the liquid are selected such that Hansen spheres of at least two types of the solid particles and a Hansen sphere of at least one type of the liquid mutually overlap, and a Hansen solubility parameter distance to water of at least one type of the solid particles of which the Hansen spheres overlap that of the liquid is greatest among all solid particles used in manufacturing of the dispersion body, and used to manufacture the dispersion body.

A thermal insulation member is directly or indirectly sandwiched between a first object and a second object and thereby suppresses or interrupts heat transfer between the first object and the second object. The thermal insulation member comprises: a first main surface opposed to the first object; and a second main surface positioned on the opposite side from the first main surface and opposed to the second object. The thermal insulation member has a porous structure of ceramic having pores. ZrO.sub.2 particles and different type material exist on surfaces of the ZrO.sub.2 particles form a skeleton of the porous structure. The different type material includes at least one selected out of SiO.sub.2, TiO.sub.2, La.sub.2O.sub.3, and Y.sub.2O.sub.3.

The invention relates to a method for utilizing mineral materials for additive manufacturing that can be implemented more quickly, more economically and with greater technical simplicity, in comparison with common additive manufacturing, by virtue of controlled expansion in the sintering process by means of a laser source. The entire production process is free of organic materials and allows previously unfeasible end uses in the fields of acoustic insulation, thermal insulation, fire protection, filtration, design objects and lightweight components to be realized. In particular, the invention relates to a method for producing a product by means of 3-D printing or additive manufacturing, wherein an open-pore lightweight part is constructed layer-by-layer, without the use of organic binders or other organic auxiliary agents, from a pulverous mineral starting raw substance of natural origin, which raw substance is obtained without chemical alteration of the solid constituents of the natural material, and wherein, beginning with the second layer, the most recently applied layer is bonded to the surface of the existing body of the lightweight part by means of immediately subsequently performed direct selective laser sintering.
