Timber Spatial Joint
Concept
The aim of this timber spatial joint was to explore the bending technique applied to plywood or MDF using kerfing but also apply it in 2 directions instead of 1. The bent joint is then inserted into the circular wooden sticks and fixed in place using a wooden dowel.
Production Process
First Trial: Bending Acrylic with Heat
Challenges Faced:
- Difficult to bend the acrylic in Opposite directions as the center is affected by one of the directions.
- Difficult to align the grooves in the joint with the fingers on the bottom supports.
- Time-consuming
Second Trial: Bending MDF using Kerfing Technique
Challenges Mitigated:
- Easier to bend in both directions
- Grooves easily align with fingers

CNC MILLING
The CNC Milling machine produces high accuracy parts from Rhino or CAD with a high level of automation.
As a subtractive manufacturing technology, the CNC cuts away pieces from a block. This can create complex 3D forms in relatively quick timeframes.
For this exploration we are provided a hexagonal module of 360x180mm.
We developed a circular pattern structure that could have different heights, depths, and areas all through a grasshopper script. We imagined the script being tailored depending on weather and lighting needs for a facade.
