RESULT

In this workshop we generatived forms through computational design, starting by  2D grid patterns. Using Kangaroo, a Physics Engine of Grasshopper, we explored and simulated the emergence of different formations of an elastic lattice. By extracting the desired state of the aforementioned system we moved on to the materialisation of this form, using modular laser cut units connected by “smart” joints. The challenge was to work with a non structural material as plexiglass and find ways to boost its stiffness. Therefore the students went through a series of material experimentation, including heat bending techniques. The final result is a 1:1 lightweight exhibition stand.

INTRODUCTION

Every natural formation is the derivative of perpetual material transformations, external influences and forces. The complexity of this process of generative morphogenesis can be analysed by studying the repercussion that physical forces imply to a given structure or pattern, through geometric laws. As D’ Arcy Thompson said:

“The form is a system which organises itself in the presences of both internal and external forces and these organizations can shape patterns traced thr ough mathematical rules”.


BRIEF

In this workshop we will understand how to create such generative forms through computational design, starting by simple twodimensional grid patterns. Using Kangaroo plugin, a Physics Engine of Grasshopper, we will explore and simulate the emergence of different formations of an elastic lattice.

By extracting the desired state of the aforementioned system we will proceed with the materialisation of this form, using modular laser cut beam units connected by “smart” joints. By keeping the length of the beam stable throughout the structure, the global deformation of the structure consists of the local geometrical deformation of each node. Consequently, the detailed geometry and the material system of the joint will allow or prevent the elasticity of the form, embedding in the physical structure the properties of the computational process followed for its generation.


TOPICS

Generative Design
Kangaroo Physics
Digital Fabrication
Material experimentation


STRUCTURE

The syllabus of the course is divided in physical (P) and digital (D) experimentations which take place simultaneously as the one informs the other. The focus lies on the digital fabrication and connectivities of a material system but a basic practical and theoretical background of computational design supports the process.

D: Introduction to Rhino Grasshopper and Kangaroo
P: Laser cut exercise, cut settings for cut, engraving and folding, material nesting and labeling
 
Day 2 / Tuesday 20 (groups of 3)
D: Digital experimentation and form finding
P: Experimentation of a node detail, press fit technique and tolerances
 
Day 3 / Wednesday 21 (groups of 3)

REQUIREMENTS

The workshop is open to all participants, no previous knowledge of Rhinoceros, Grasshopper is required (but useful to have basic knowledge of these software programs). Participants must bring their own laptop with a pre-installed Rhino (No additional cost for the participant &  can be downloaded as evaluation version, with Grasshopper plugins).
