A residential or commercial building, structure, or building component can include an exterior member, interior member, and plurality of cross-members spatially disposed therebetween. Each of the exterior member, interior member, cross-members can be formed from a multi-layered stack of polymeric material made by a layered three-dimensional printing process, and all can be monolithically integrated. An exterior surface region of the exterior member can have an integrally formed surface finish. Overlying finishing or connective layers can be added. The exterior and interior members can be configured in a parallel arrangement to form a rectangular or curve shaped building block. A fill material can be disposed into openings between the exterior and interior members, and an interior surface region at the interior member can include a cavity configured for an electrical box, plumbing, or a sensing device.

The invention relates to a web (1) with a web base (3) and a tube segment (4) made of a wood-based material or bamboo, wherein the tube segment (4) comprises a wall (5) which is delimited in the circumferential direction of two cut ends (8, 9), and wherein the tube segment (4) is mechanically connected to the web base (3) by means of at least one of the cut ends (8, 9).

The invention further relates to a sandwich plate (2) with a plate layer (11) and a core layer (13), wherein the core layer (13) comprises at least one web (1) according to the invention which is mechanically connected to the adjacent connecting face (14) of the plate layer (11) by means of a cut face (6, 7) of a tube segment (4), wherein the cut faces (6, 7) delimit the wall (5) of the tube segment (4) in longitudinal extension direction.

The invention further relates to a sandwich block (26) and a methods for producing a sandwich plate, a web (1) and a sandwich block (26).
