123D Make + Adobe Illustrator

Load in 3D Model in 123D Make with extension .obj from Meshmixer app.

Some errors might occur, stating that the model needs to be shrinkwrapped in order for the form work to work properly.

After shrink-wrapped it to the desired level, then the cutting could be done properly. There are several methods in building the framework. In the end, I chose stacking method as the other method such as interlocking did not work properly.

Red cutting means there are some error in the model, thus the form work could not be done

In order to get a finer curve-shape of the actual model, we need to add more layers horizontally and vertically. The scale can be adjusted as well. I scaled it down from 260 mm to 200 mm. 

For laser cutting, I am using plywood 600 x 300 mm with thickness of 3 mm. For the final result, I need to have 9 sheets with total of 54 parts needed to build the actual model.

Exporting all the sheets into .pdf and then doing some adjustments in Adobe Illustrator (based on module BHSM015: Laser Cutting - VLS 3.50 (2016)

Changing line color from the actual document to make color red to blue #0000FF and blue to red #FF0000. Red means cutting and blue means engraving.

Stroke weight needs to be changed to 0.001mm

Check the boundary also as the laser cutter might not cut shapes properly around the boundary.
