Visual, flow-based programming environments in architecture and design are built to control data flow but not process flow. However, controlling the process flow is essential for interacting with robotic fabrication processes, so that they can react to input such as user interaction or sensor data. In this research, we combine two visual programming environments, utilizing Grasshopper for defining complex, robotic toolpaths, and Unity Visual Scripting for controlling the overall process flow and process interaction. Through that, we want to enable architects and designers to define more complex, interactive production processes, with accessible, bespoke user-interfaces allowing non-experts to operate these processes -a crucial step for the commercialization of innovations. This approach is evaluated in a case study that creates a mobile, urban microfactory that prototypically fabricates location-specific objects through additive manufacturing.

“…This research builds on current studies in spatial 3D printing methods and presents novel algorithmic methods and geometric generalization to robotically fabricate triangulated tessellations that conform complex surfaces. The particularization of models for creating the voxelized approximation of a shape is one method [6], [7], [8] that has allowed designers to defy the layerwise stacking principle of standard AM and allowed the creation of complex spatial arrangements (Figure 2). Digital tools in design for fabrication integrate geometric logic of constructability and design goals [9].…”

Current advances in construction automation, especially in large-scale additive manufacturing, highlight the vast potential for robots in architecture. Robotic construction is unique in its potential to reproduce highly complex structures. To advance the question of how rapid prototyping techniques are adopted in large-scale 3D printing of forms and structures, this paper presents computational methods for the design and robotic construction of cellular membranes. This research presents a comprehensive morphological model of structurally differentiated cellular membranes based on the theoretical biology model of hierarchical structures found in natural cellular solids, and, more specifically, in trabecular bone. The morphological model originates from a system of forces in equilibrium; therefore, it presents the geometric homology of a static tensional system. This research offers a methodology for the design and manufacture of meso- to large-scale triangulated geometric configurations by discrete design methods that are suitable for the robotic fused deposition of lattices and their architectural implementation in the automated manufacturing of shell structures. First, this paper explores how a form can be digitally created by geometrically emulating a given static system of forces in space. Second, inspired by the complex mechanical behavior of cancellous bone, we apply hierarchical principles found in bone remodeling to characterize discrete units that conform to continuous trabecular-like lattices. We study the geometry, limitations, opportunities for optimization, and mechanical characteristics of the lattice. The computational design methods and additive manufacturing techniques are tested in the design and construction hierarchical structures.

“…Zhao et al [ZGH∗16] generate contour parallel fill trajectories that form singly connected spirals within a contour, leading to a continuous fill with smooth trajectories. Soler et al [SRJG17] create 3D trajectories as Hamiltonian cycles in grids for wireframe 3D printing. In the context of two‐photon lithography, Dahaeck et al [DSL18] divide a surface to be manufactured in a process akin to a Centroidal Voronoi Tessellation and compute a Hamiltonian path within to obtain a continuous trajectory.…”

Isotropy and anisotropy are optimized in terms of distribution of angles, while alignment is specified in a vector field (here parallel to the boundary). For the three curves, the number of transitions between the two letters of the logo is minimized. (d) Multi-material 3D printed cube, with isotropic layers optimized by our approach.
