Scale Model – Layers and Laser Cutting

We began the process of constructing a scale model by separating the top and bottom portions of the 3d model of the shape. Each layer is separated into two portions because the top and the bottom of each layer are space out in order to be beveled by the CNC router. In order to format the design for the laser cutout we needed to export organized 2d files of the layers separated for the final 3d shape into Adobe Illustrator.

In experimenting with fabricating the shape we initially struggled with configuring software in order to splice the final shape into multiple layers, and then for the scale model, 2d layers. This export identifies 50 total layers of the shape exported from the curve layout in a software program called Rhino. Constructing the shape in itself uses spatialization and impulse response proved to be difficult, and the organization of these layers was as well. The format was reconfigured to be placed on a 2d plane and we ended up using jpeg exports into adobe illustrator for the scale model. The sides were widened and the shapes needed to be grouped in order to be analzed by the laser cutter.

This is how we layed out the sections onto an Adobe Illustrator file in order to maximize space used on the 3mm birch plywood sheet.
