Abstract: Described is a method of preparing foams, wherein a suspension comprising an aqueous liquid, particles and at least one surfactant is provided, wherein the at least one surfactant at least partially hydrophobizes a surface of the particles, and wherein the suspension comprising the particles having the at least partially hydrophobized surface is foamed. The at least one surfactant is selected from surfactants having a backbone chain comprising at least nine carbon atoms, the at least one surfactant preferably being an amphiphilic molecule consisting of a tail coupled to a head group, wherein the tail comprises the backbone chain comprising at least nine carbon atoms.

Abstract: The present invention provides additive manufacturing compositions, also referred as “inks” in the field of additive manufacturing, which can be fine-tuned with respect to porosity by varying the intensity of the photopolymerisation light source and which can further be used to obtain objects out of glasses, ceramics or glass-ceramics and their respective alloys.

Abstract: An additive manufacturing process for the manufacture of an object in an additive manufacturing apparatus, wherein the object is formed by one or several individual solid filamentous units. The additive manufacturing process comprises the steps of discharging a polymer composition in a molten state from a nozzle of a print head, thereby imparting an orienting flow on the polymer composition in a molten state being discharged from the nozzle of the print head and depositing said discharged polymer composition in a molten state along at least one predefined path and allowing the thus formed one or several filamentous units to solidify such as to form one or several solid filamentous units of the object to be manufactured. Optionally, the previous step may be repeated until the object is formed. The polymer composition comprises a thermotropic liquid crystal polymer as the polymer component of the polymer composition.

Abstract: An additive manufacturing ink composition includes a polysiloxane bearing a plurality of alkenyl groups and a crosslinking agent bearing a plurality of thiol groups. The polysiloxane and the crosslinking agent form an emulsion.
