W2 - Synergetic Joints

This project was inspired by Buckminster Fuller's synergetics. One of the challenges in the synergetics model is the performance of the same module can vary based on its computational rules, however, this homogeneity leads to heterogeneity in physical fabrication since different performances lead to different forms. I intend to fabricate homogeneous modules that inherit performative capacity from the computation rules, and construct a tectonic system using these synergetic modules.

This is a very simple shape made from cutting and engraving techniques. The engraving intends to cut through the upper and middle layers of the cardboard and leave the bottom layer untouched, therefore allowinging bending performance on the piece. The slot on three ends allows push and pull cooperative performance between pieces.

To ensure precision cut, I made a few rounds of test cuts to experiment with extreme optimization between power and speed of the laser cutter. A large cutting power will create a trapezoid cross-section shape (top layer got burned more than the bottom layer), which will create an angled joint when two pieces connect to each other. A perfect engrave cut is also required for the bending performance (cutting on the bottom layer will create a weak structure, and not cutting through the middle layer will make it difficult to bend)

After a few tests, an optimized setting for 1/8" cardboard is:

engraving - 25% power + 75% speed

cutting - 60% power + 75% speed

then just play with them like Legos
