The invention relates to a method, a device, a binder system, and a material system for producing components using layering technology, wherein the temperature in the building space and/or in the applied material is set to at least 70 C. and maintained for at least 2 hours. Areas on which binder has been selectively applied, solidify and form the component.

A structure including a hollow porous material with an architected fluid interface to the hollow porous material and methods of forming the same. The architected fluid interface may be in the form of a manifold with tapered openings, each providing a gradually narrowing transition to the hollow channels within which fluid may flow through the hollow porous material. The material may be formed by forming an open-celled sacrificial scaffold, immersing one surface of the open-celled sacrificial scaffold in a bonding agent, attaching a face sheet to the surface to form a sacrificial scaffold assembly, coating the assembly with a coating material, and removing the sacrificial scaffold assembly.

A resin composition for forming a structural element such as a flooring panel includes a resin system including: 45-60 wt % of a plant-derived polyfurfuryl alcohol resin; up to 15 wt % of a non-structural filler such as talc or jute fibre; and 35-40 wt % of a glass fibre. 5 A method of making the structural element includes mixing the resin and filler to produce the resin system; laying up multiple layers of the resin system and the glass fibre in a mould; subjecting the mould to an initial heating profile in an initial resin curing step so that the resin system undergoes a condensation reaction and such that substantially all of the water produced in the condensation reaction has been removed, wherein the heating profile comprises a first, an intermediate, and a final temperature. The product is subsequently subjected to a post-curing step comprising a Diels-Alder reaction.
