123D Make
Software Installation
After scanning the model through 123D Catch and discarding all the unwanted bits though mesh mixer, it is now ready for import into 123D Make to create various patterns of the object. This software allows you to generate templates of your desired model for laser cutting and assembly later.
Importing
Simply download Autodesk 123D make onto the computer and import the ojb file into this software. After loading into 123D Make and it is imported, there are different options of shaping this object through stacking, interlocking and radical techniques shown below. The software will generate a pretty good 3D model of the object for creating a solid contour.

radical slices
Previously I have used interlocking as a method of creating my mold for hammering. After my first attempt of laser cutting, I realized there was a problem with the interlocking hence I underwent with stacking which is a better approach.
Preparation for laser cutting
The autodesk 123d make generated over 50 pieces which is not ideal for laser cutting. it is expensive and too much to laser cut. you are able to define the number of templates for cutting. as a result I reduced the size of the model creating roughly 32 pieces with a maximum of 3 templates to cut. The final step is to export these templates as PDF files. Click on the 'Get Plans' Tab and save them onto your usb or hardrive.
The next step is to import these PDF files into Adove Illustrator to modify the settings for laser cutting. The dimension of the material sheet you choose to use should be 600X300 as it will fit perfectly onto the laser cutting machine. It is important to note that the outlines of the template should be red for actual cutting and blue for scouring shown above. The 123D make will produce an original template shown below which is not ideal for laser cutting. In addition, the line weights should be set to 0.001 for the laser cutting machine to cut effectively.
