123D Make

123D Make

 Whit a mesh which already fixed by meshmixer, I can start to explore our laser cutting panel via 123D make. 
There are several things have to be aware, the first thing is the size of the laser cutting material. The maximum size of laser cut machine in UNSW Fab Lab is 600 mm*300 mm. 
Another important thing is the thickness of the material, I chose 3 mm thick plywood to be my laser cutting material. My laser cut model is an interlocked  model which will create a waffle structure (figure 1).
For my personal experience, if the model is a interlocked model,, it is batter to make 0.5 mm thicker when you inter the thickness in 123D make. Whit this setting, it will be much more easy to join each piece together especially for plywood as plywood is a material which  won't always be flat. 
The laser cutting layout should be like figure 2, it will have a preview of the layout at the right side. As the preview, my model will cost two sheet of plywoo and it will be 14 parts to join together.
