The assignment for this week is to create a press fit model using computer controlled cutting. The laser cutter, as a machine, allows for precision – reducing waste, eliminating the need for adhesives, etc. The assignment speaks to understanding materiality, that is, material thickness, strength, its particulars. For a simple assembly, I thought about an unfolding a box, and after several tests, came up with a unit with four pinhole notches that would allow for aggregation of a single type of module and expansion in the x, y, and z axes.

the simple x-cross connection allowed for flexibility in the construction of the whole; the units could collapse and expand, in the x, y, and z.

Make sure to test the connection between two units; chamfers help // Using parametric software that has control of the notch size would be incredibly helpful – in this case, it wasn't entirely necessary since a single unit was repeated, however, that type of control and workflow would be beneficial for future projects // allow time for development, the efficiency and speed of the laser cutter could allow for a very tight feedback loop between modeling and making – it is much more helpful to cut an initial set of units, test its potential, and then return to modeling. Work back and forth between digital and physical.
2 workflow/parametric beginnings?
I began to create files and a workflow for a basic waffle structure, a simple bulge. I started to learn grasshopper, and would like to understand it can be utilized in the context of press-fit kits (thinking of how to make something big.) A simple script allows one to create notches at the intersections of two planes within a 3d model. The script allows the user to specify the width and depth of the notch. [see example here] [and here] I'd like to understand this workflow (initially orthogonal x/y intersections, to more complex/less defined) - updates to come.

These two images are the resultant topographical lines in the x/y and the z for the bulge above, created to test scoring variances using the 3D settings in fablab. [reminder, white=bright=power]. Unfortunately, ran out of time. Hopefully will be able to sign up for some LC time this week and test this.
