Examining the Interactions of Design Parameters in the LDM of Clay as the Basis for New Design Paradigms

Abstract

In the future, architects will not only develop digital designs based on existing technologies and concepts, but will also pursue and experiment with various forms of self-developed processes. The following empirical study deals with the materialization of digital instructions and machine parameters in 3D-printed clay elements. Specifically, forms of materialization are investigated in the transitional area where ideal geometrically defined data and process-related material information intersect. Liquid materials generate additional information quality through their material-immanent shape-forming properties. In previous studies, this somewhat complex material behavior was considered rather problematic and attempts were made to reduce the flow behavior of materials in the printing process. In contrast, this study examines the special possibility of liquid deposition modelling and present new ways of dealing with the material viscosity during and after the printing process.

Forming of Additively Manufactured Ceramics by Magnetic Fields

“…This study was based on the following assumptions: (1) The developed composite material has deformation, drying, and sintering behaviors similar to pure clay bodies, whose behaviors in LDM have been described in previous publications [18]. (2) The additive build-up process of clay bodies by the LDM system, Delta WASP2040 Clay Printer, through G-code instructions is well-known.…”

Dynamic Extrusion Control in Spot Deposition Modeling for Porous 3D Clay Structures

“…Considering these results in combination with the results from the layered and semirandom SD described at the beginning of this section, vertical strands of 40 mm were modeled onto the single-curved, digital surface with an additional travel path, which deflects the vSDs away from the face of the surface. Under consideration that, in LDM, the direction of the tool path has a non-trivial effect on the geometry, the bending direction was alternated in each vertical strand [29]. Using this material deposition strategy, the vSDs were successfully stacked on top of each other and produced surfaces with strong reliefs (Figure 11).…”
