Phase Change

PHASE CHANGE
Explorations in Robotic Forming of Thermoplastic Materials

This workshop will explore opportunities to overcome tooling limitations in the formation of individualized thermoplastic building components using robotic formation during phase change and speculative additive robotic processes (3D Printing). Explorations will include the translation of the rigid ideal of computational design space to the soft reality of an uncertain built environment as mediated by the industrial robotic work cell. In this case, the industrial robot precisely translates the digital geometry but the final form is characterized by the uncertainties of the thermoplastic material behavior during phase-change. The resulting artifacts will emerge from the integration of the precise and the imprecise through a feedback loop between the digital design environment and the results of a series of physical material experiments. Material properties are considered intrinsic to the design process and the robotically controlled fabrication process will be saturated by feedback from the behavioral logics of the material itself. The exploration of complex material behavior during phase-change will extend to the introduction of novel additive manufacturing technologies through the combination of generic robotic manipulators and custom end effectors. The introduction of additive processes begins to speculate on fabrication scenarios that distance themselves from current linear file-to-factory based methods and industrialized production-modes as well as introduces opportunities for the eventual introduction of Additive Manufacturing in Architecture.

What participants can expect to learn in this workshop

Participants will be introduced to concepts relating to manufacturing of thermoplastic materials through a variety of processes including relevant material properties, types, and behaviors. This discussion will also introduce issues of production volume relative to architectural customization potential. The workshop will seek to overcome limitations with exiting polymeric material systems to realize robotically formed-individual components and to this end, will cover specific skills relating to robotic fabrication including integrated design-robotic manufacturing workflows, real-time material feedback, and research methods relating to the exploration of novel materials and processes. Fundamentals of Additive Manufacturing Technologies will be discussed and opportunities for architectural applications will be explored in detail. Issues of the application of the industrial robotic work cell as a prototyping methodology will be explored and specific technical skills will be developed including: Set up and calibration of the work cell, programming interfaces including Rhino-Robot and proprietary Robotic Programming environments (ABB RobotStudio), and a variety of Grasshopper-based automation tools. Beyond the exploration of thermoplastic material processes, the workshop is suitable for those interested in incorporating the industrial robotic work cell into their design curriculum and/or practice.

Prerequisites

Familiarity with Rhino and Grasshopper is ideal but the workshop will tailor to those with all levels of computational design experience.
Participants are asked to bring their own laptops. Software will be provided on standalone workstations but participants are encouraged to be prepared with at least Rhino 5 and the latest version Grasshopper installed, DRG-PRG will be provided.
