New ways of getting beyond 2D
One of the things I love about digital fabrication is the process of elevating 3D forms from 2D materials. “2D materials” – anything that comes in a sheet – have all kinds of inherent efficiencies in terms of modelling, manufacturing, transport, and assembly, but it takes a certain amount of mental gymnastics to translate them into 3D objects. I stumbled across this image today and it opened up a fascinating new world for me – a construction technique known as curved folding.
The model above is made by Yoshinobu Miyamoto (flickr | interview), an architect and teacher at Aichi Institute of Technology in Japan. In researching the background of this model, I came across Curved Folding: a network of more than 300 members working together to create an open CAD standard for representing and modelling curved folding geometries.
Some of the gems I found in the Curved Folding network include Ran Amatai: a designer who creates aluminium furniture using a combination of strict linear creases and organic curving folds, utilising both the material’s rigidity and malleability.
Gregory Epps, the founder of the Curved Folding site, also runs Robofold, a fabrication facility for folding metal sheet using industrial robotic arms. If you happen to be in London with a spare £800 you can take a 4-day workshop where he will take you through the process from paper experimentation to CAD modelling to final metal construction.
I’m on holiday for the next two weeks but when I get back I’m going to start playing with some of these folding techniques to see what I can create by laser-engraving some of the thin materials on offer here at Ponoko.
These free software tools from Tomohiro Tachi look like an ideal place to start simulating these folded models.
