Adventures in Brunelleschi
Chapter 4
Much like the work of Cristos, Brunelleschi's famous duomo in Florence has been draped and has become a surface, stripped of material, fenestration and articulation. It is intended that this will be a backdrop for the script used to generate curves on a surface. This mentioned method seeks to generate toolpaths that the robot will need to follow.
The physical outcome will again be extrusion of polypropylene. The resulting curvature bears resemblance to the original structure, but is distant enough to stand autonomously as well. Optimism runs high with the sinuous quality of the curves as shown in the line images generated.
Unfortunately, actual attempts to extrude the curves were unsuccessful. Though it is possible to extrude without the use of supporting structure or mold, some motions are not possible given the geometry of the nozzle and the heat it produces. Travelling in an upward motion is simple, as the hot nozzle is moving away from the material it is deposition. But as the path continues, the nozzle deposits material and that it will soon come into contact with, melting what it has just made. This method may work with further investigation where only toolpaths in an upward motion are used or the nozzle position changes throughout the path so that it will not contact previous extrusions.
