Here are some links that helped me get started with laser cutting. I was particularly interested in patterns to design 3D objects from 2D shapes, and the workflow for exporting a 3D model to individual 2D faces that can be sent to a lasercutter.

1) Nicely described projects how to go about designing a simple box using the…

– tab-in-slot method

– tooth-interlock method

2) As laser cutters work in 2D, they require a 2D model of the object you want to build. If your object of choice is a 3D object, it might be easier to design / prototype it in 3D and then export to 2D, rather than designing it’s 2D components from scratch. This tutorial starts with a 3D model in Google Sketchup, then exports it to a 2D vector graphic ready for laser cutting.

Download the plugin used to export a Google Sketchup model to SVG here:
