A Process-Centric Approach for Teaching Digital Fabrication

A Process-Centric Approach for Teaching Digital Fabrication

Valdes, Francisco; Cavieres, Andres; Gentry, Russell

Article:

New generation of fabrication machines, such as 3-D printers, do not use “real” materials nor processes generally used in building construction, and so further exacerbate the disconnect between laboratory-based prototyping and full-scale building construction techniques. This research critically reviews the results of a graduate fabrication course from a process-centric standpoint. Students in the course create specification for fabrication and assembly activities through a diagrammatic language that integrates several types of construction knowledge such as design, material properties, machine constraints, and assembly guidelines. This document presents the foundations of the methodology, and discussed the results based on two criteria: Process Modeling and CAD/CAM workflow.
