Because of the detail I often use the school laser cutter to cut out the small parts. I have put some pictures here to show you some of my work.
The first pictures show a design for an enlargement for a school. I undermined the school and used a stair like architecture that's multifunctional. (the trees are also made with the laser)
The second series is a conceptual building where the units are supported by one big shed like structure. For this design I used 123D make from autodesk. A very handy program that turns 3D objects into 2D files which can be cut out in de laser cutter.
I also made an experimental project where I used the laser cutter to create cardboard gears as big as my dumb ! So the possibilities with this machine are infinite.
Hopefully you gain some inspiration for your future projects !
