The purpose of the present invention is to provide a liquid resin composition which includes polysaccharide nanofibres, and which is used in a three-dimensional moulding production method in which a moulding obtained by curing the resin composition by irradiating the resin composition with active energy rays is three-dimensionally formed, wherein unevenness in strength in the height direction is not readily produced in the formed three-dimensional moulding. The present invention relates to a liquid resin composition which is used to produce a three-dimensional moulding, and which three-dimensionally forms a moulding as a result of being cured by being selectively irradiated with active energy rays. The resin composition includes an active energy ray-curable compound and polysaccharide nanofibres. The ratio of the number of polysaccharide nanofibres having a branched structure to the total number of polysaccharide nanofibres is less than 20%.

The invention relates to a molding material, consisting of or comprising an organic binder, the organic binder being a wax or comprising a wax; and a filler mixture, the filler mixture comprising or consisting of a mineral filler and a fibrous material, wherein the wax is contained in the molding material in a content of between 3% by weight and 23% by weight, and wherein the mineral filler is contained in the molding material in a content of between 75% by weight and 95% by weight. The invention further relates to a molded part made of such a molding material, a method for producing a molded part, and the use of a molding material for forming a molded part.

Three-dimensional printing kits can include a powder bed material and a fusing agent to selectively apply to the powder bed material. The powder bed material can include polymer build particles and cellulose particles. The cellulose particles can be chemically and thermally stable at a melting point temperature of the polymer build particles. The fusing agent can include water and a radiation absorber to absorb radiation energy and convert the radiation energy to heat.

The present invention related to a thermoplastic composition, suitable to be submitted to common methods of heat forming, or thermoforming, of thermoplastic materials, as well as the thermoformed composite material which is obtained/can be obtained from said thermoplastic composition, said thermoplastic composition and said thermoformed composite material derived therefrom comprising the combination of cellulose with a thermoplastic material comprising a hydrolysable or hydrosoluble polyhydroxylated polymer, such as starch or a polymer based on polyvinyl alcohol (PVA), wherein cellulose is available in an amount ranging from 30 to 60% by Weight, preferably from 40 to 60% by weight, said percentages being calculated on 100 parts by weight of the combination of cellulose with the thermoplastic material comprising a hydrolysable or hydrosoluble polyhydroxylated polymer.

A laminate, containing two or more polyolefin resin layers, wherein at least one polyolefin resin layer (A) contains a cellulose fiber including a cellulose fiber having a fiber length of 0.3 mm or more dispersed in the layer; a content of the cellulose fiber in the polyolefin resin layer (A) is 1% by mass or more and less than 60% by mass; and wherein a polyolefin resin layer (B) different from the polyolefin resin layer (A) is laminated in contact with the polyolefin resin layer (A).

Polymeric aerogels, articles made from the polymeric aerogels and methods of making the polymeric aerogels are provided. The aerogels are made e.g. from crosslinkable monomers such as isocyanate monomers or phenolic monomers and a filler comprising crosslinkable hydroxyl groups. The filler may be natural (e.g. wood flour) or synthetic. The aerogels and products made therefrom exhibit low thermal conductivity and are mechanically strong. Due to their physical properties, these materials are used as e.g. building envelope components, such as walls, roofs and frames, to improve the thermal performance thereof, and may be used in a variety of other applications such as sound and insulation barriers in mechanical equipment, cryogenic containers, etc.

Making a carbon aerogel involves 3-D printing an ink to make a printed part, removing the solvent from the printed part, and carbonizing the printed part (with the solvent removed) to make the aerogel. The ink is based on a solution of a resorcinol-formaldehyde resin (RF resin), water, and an organic thickener. Advantageously, the RF resin contains an acid catalyst, which tends to produce carbon aerogels with higher surface areas upon activation than those produced from methods involving an ink composition containing a base catalyzed resin.
