The Gaudi stool designed by Dutch designer Bram Geenen is based on the catenary curve that when reversed a strong form for taking compression forces emerges. The stool consists of a thin shell structure and a beam-grid substructure that resists the bending of the shell, made of carbon fiber. Using the technique of rapid prototyping the complexity was achieved creating a lightweight stool weighing only 1 kg. Stool is made of carbon composite and polyamide.

Design: For the milling project the team explored creating a tile shaped by defining a 3D trajectory for the machine to fallow.  By using the milling as an egravement tool the tile was given a surface which both showed fragments of a curvilinear surface and a pattern which can be connected with other similar tiles in order to create a complex and interesting design.  All lines forming the patterns in the tile share a similar border configuration in such a way that every side of the square can be connected with any other side and still keep a continuos profile.  In total, 6 different pattern configurations can be achieved by combining any 4 tiles.





Optimizing Milling Time: During the process of designing the trajectory of the milling machine manufacturing time was taken into consideration.  The shape of the tile was though is such a way that the final shape could be achieved by using a single milling mode (engravement).  All pattern lines where connected in order for the machine to do all cuts using a single trajectory.  Because the softness of the foam being milled, it wasn’t necessary to do a rough cut, reducing even more manufacturing time.  As a result of these optimizations the milling time was short and ideal for mass manufacturing.

Material: For casting, experimentation was done with the process of freezing materials inside the mold.  The mold was made water proof using latex and silicone in such a way that is was possible to fill it with any liquid.  Gelatin and Water were chosen to experiment with this process, taking advantage of the rigidity of ice and the consistency on gelatin. The end result is a transparent colored iced sculpture showing a segments of a curved surface on a curved path.
