title Digital Dexterity. Freeform 3D printing through direct toolpath manipulation for crafted artifacts
source ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 266-275
summary The research presented here investigates an approach to FDM Freeform 3D printing that fully utilizes simultaneous x, y, z axis movement for the production of designed artefacts. Most Freeform printing techniques create bands of space frame type structures, often defined by structural pursuits. Here, a Form Responsive Method is used, which exploits the design opportunities of synchronized three-dimensional movement depositing extrudate in patterns of lines and curves that embrace functional, aesthetic and tectonic qualities, all influenced by an industrial design perspective. The system allows the designer complete control of the pattern and deposition of the material in relation to the printed artefact. The form and details are designed concurrently by direct manipulation of the toolpath whilst considering material deposition and structural integrity. This method of working requires intimate understanding and control of both software and hardware to craft the artefact to the desired design. Different aspects of the technique and challenges are described and discussed through a range of artefacts of different scales from utensils to furniture items.
