A novel method for high-resolution imaging of coating distribution within a rough-textured plywood surface

A new method was developed which enabled us to obtain high-resolution images of the distribution of an oil-borne stain in a saw-textured plywood surface. The method involved treating 90 μm thick plywood sections, which had been cut transversely through the wood-coating interface using a sliding microtome, with osmium tetroxide (OsO₄) prior to examination with a field-emission scanning electron microscope (FE-SEM) operating in backscattered electron imaging (BEI) mode. The combination of OsO₄ staining and use of FE-SEM-BEI afforded excellent contrast differentiation between the coating and wood cell walls, revealing coating penetration into even nano-size cell wall cracks and delaminations formed during band-sawing of the plywood. The novel technique described adds a new dimension to probing wood–coating interface.

Fabrication Agency: Landesgartenschau Exhibition Hall

Advances in computation challenge established design approaches in architecture through a much deeper integration of form generation and materialisation. Tobias Schwinn , Research Associate at the Institute for Computational Design (ICD), University of Stuttgart, and Guest-Editor Achim Menges , Director of the ICD, introduce how the potentials and constraints of robotic fabrication can now be explored as generative drivers in agent-based design. This enables architectural innovation in unison with fabricability, structural capacity and spatial performance, as demonstrated by the Landesgartenschau Exhibition Hall in Schwäbisch Gmu"nd, Germany, the world's first building with a robotically fabricated segmented timber shell as its primary structure.
