Workshop 1

Multi-material Assembly (MA)

Keywords Multi-materiality, Assembly, Material Computation, Production Computation, MultiMode Robotic Production, Hybrid Properties, Material Gradients,

Context Advancement in design computation and robotic production is leading to novel methods of material fusion on multiple scales. In architectural design, systematic methods of computing, modeling, simulating and representing multi-materiality and assembly are required. Furthermore, hacking and modifying production methods are leading to efficient and meaningful materialization processes. In this context, the workshop on Multi-material Assembly (MA) aims to explore and establish computational design to programmable production and assembly processes.

Objective & Focus The focus of this workshop is at the intersection of multi-materiality and assembly of multi-material components. The objective is to exploit informed multi-material D2RP&O approaches. Informed in this context mainly refers to structural, functional and environmental parametres. Therefore in each project one or multiple parameters will be chosen to inform the design. Modeling and production of multi-materiality as well as assembly requires integration of physical computing with materialization sequences. For instance, customized toolpath or G-code generation methods, voxel based representation of materiality, Finite Element Methods (FEM) of structural simulation, etc. Furthermore, informed assembly allows for growing larger than the size of allowed by the production setup. This entails a comprehensive understanding of structural modeling ranging from fundamental structural design concepts like degrees of freedom in multiple direction to multi-materiality itself that may improve the local or global stability and coherence of the assembly.

Workshop Structure During the MA workshop, students will work in groups and will explore 3 main aspects of assembly: Group 1: Porous-solid interlocking systems Group 2: Soft-rigid intertwining systems Group 3: Physical-digital interweaving with existing topologies

Design, Working Packages & Deliverables The initial input topology to this workshop will be a section part of previously designed stage-pavilion titled Echosphere (http://gsm.hyperbody.nl/index.php/Msc2G3:Group) and/or MSc 2 prototypes from previous MSc 2. This initial input is only a departure point, which during the workshop may differentiate depending on the focus of each group. The key working packages of this workshop are divided into two main categories. First category refers to computational design methods of multi-materiality and assembly. The second emphasises the bridging of digital design approaches with physical programmable systems like 3D printers and robotic arms. Respective feedback loops shall be used as inputs that inform the design in terms of materialization. The workshop deliverables include design computation methodologies. These computational models includes systemic representation of workflows and data exchange between multiple plugins and sub-algorithms as well as interoperability between digital and physical modules. Each group may deliver specific customized methods of material properties and behaviour simulations implemented in the design process. Moreover a flowchart diagram of process as well as a short video of design to production experiments and prototyping are considered as key deliverables of this workshop. Physical prototyping of the the design is not obligatory in the prototyping planning session. Each group in dialog with tutors will decide upon either physical prototyping or proof of concept documentation of the process. Production methods available in this workshop will be 3D printing with an ultimaker 2 and a KUKA robotic arm.
