The design idea used to create the tile was a method of force fields. In creating this seamless pattern multiple spin forces were merged together and the effect of field lines was extended for better visualization and incorporation into the water evacuation system.

Force fields working with a different set of constraining circles.

Every line of the system is represented as an “escaping” curve. Each point tries to get away from the force field quickly, leaving those paths behind and creating the data tree structure. By playing with parameters like length, force, radius, distance in between, we could create a controlled distortion according to these field lines and force center.

Water evacuation tangencies meet force fields

The tile is divided into 3 parts according to the water evacuation points on the external edges: 2, 3 and 4. The force fields were placed accordingly on splines starting from these points of reference.

Overall composition of 6 tiles

The slope of the tile decreases gradually outwards following the rhythm of the water canals and pattern, enhancing the water evacuation.

To discover our milling strategy we experimented repeatedly with RhinoCam. In the end, for our design, we selected the 12 mm ballmill as it gave us the optimal finish and kept our machining time within the 2 hour limit. We first ran a horizontal roughing to carve the canals then curve machining to overlay the thin contour lines. In the end we didn’t do a perimiter engraving in order to allow for continuity of the lines over the edge and side of the tiles.

METAmorphosis

The Metamorphosis project is a series of geometrical moments obtained by stretching an assemblage of arched rods. There are 3 types of 3D-printed joints: the base joint (B) fixes the structure to the board, the “plug” joint (A) slots in and twist-locks into the base joint, and the ”slider” (C) connects and moves along two adjacent rods. The geometrical moments can be created by changing the position of the plug joint in the board, or also by moving the base joint into the laser-cut holes. The chosen arrangement either expands or contracts the shape of the metamorphosing caterpillar whilst the slider deforms the body in various axes. Finally, the addition of a hinge in the board allows for the compression of the structure at an different angles. Combining 3 different strategies, the object (or parts of it) can be stretched compressed and twisted into an infinite number of geometries.

Criss+Cross

Our tower has finally been erected!

Our series of crosses stacked up on top of each other are successfully interlocking through a series of bending profiles and locking joints. From the beginning of the design process we placed a heavy emphasis on maximising our material sheets, whilst minimising cut times and wasted material. We tested many locking configurations with respect to cut sizes, experimentation with bending, and identifying stable forces. As each cross interlocks with the cross below it, two side of each face bend in opposite directions to accommodate for the insertion of the flat piece slits cut into it. We started at a width of 19cm at the bottom, and tapered the structure up to 8cm at the top. The connection to the base was solved by creating an orthogonal grid which allows the cross to anchor into securely. The structure reaches a total height of 3.35 metres!
