The Genius of Michael Hansmeyer

One of the most compelling and extraordinary piece of information that I spotted at the Heimtextil this time was the emphasis on the word Historian and the work of Michael Hansmeyer. He takes a doric column and generates a new column with algorithms and subdivision processes.

The first 2.7-meter prototype is constructed as a layered model of 1mm cardboard sheet. Further columns of milled 1mm ABS plastic layers were exhibited at the 2011 Gwangju Design Biennale.

The calculation of the cutting path for each sheet takes place in several steps. First, the six million faces of the 3D model are intersected with a plane representing the sheet. This step generates individual line segments that are tested for self-intersection and subsequently combined to form polygons. Next, a polygon-in-polygon test deletes interior polygons. A series of filters then ensures that convex polygons with peninsulas maintain a mininimum isthmus width. In a final step, an interior offset is calculated with the aim of hollowing out the slice to reduce weight.
While the mean diameter of the column is 50cm, the circumference as measured by the cutting path can reach up to 8 meters due to jaggedness and frequent reversals of curvature. The initial prototype uses 1mm grey board. Tests using ABS, wood, as well as metal are under way.

  1. Stunning images. They must have been breath-taking in reality. Thank you for sharing this work.
