Project Title:  LINE ON FIRE, or the materialization of a line in motion

Project Team: Olivier Ottevaere (PI)


This ongoing research project makes use of ruled based geometry to prototype volumetric formworks for concrete casting.
The main design-research tool is a custom made automated 5-axis hotwire cutter.

Volumes of revolution are defined by a line moving in space.

From the input of different 2d profiles, a burning line describes volumes of changing sections from 4 automated translations and 1 rotation.
By inputting specific protocols for synchronized motions, new topologies emerge described by time and movement. These are further employed to create part-moulds from EPS foam blocks for thin shell concrete casting.
