4. Digital fabrication principles
The techniques of digital fabrication generally fit into four main categories: cutting, subtraction, addition and formation. These headings are analogous to traditional processes used in architectural modelmaking and even full-sized prototyping, wherein materials are manually worked with tools to achieve the desired results.20 However, it is useful at this point to understand the differences between these procedures before we start to discuss the various equipment and machines that facilitate them.
Perhaps the most accessible and commonly applied method of digital fabrication is ‘cutting’. There is a range of different cutting techniques, but essentially they all enable the production of flat components ...
