Although it should be possible to use the CAM module to lasercut the piece directly from Fusion 360, at FabLab Reykjavik the infrastructure to do this is not set up (yet). I made a separate From Fusion 360 to Laser cutter doc explaining the workflow as it is now, starting with exporting a dxf file from Fusion.
For future use I made an Excel sheet of the information I could find on the wall of the FabLab about which settings to use for what kind of material. These settings are needed in the next step.
From here I just followed the instructions for the use of the Roland GX-24 vinyl cutter on the FabLab wiki. At point 2 this instruction says: "Choose a color, place the roll on the grey tray on the backside of the machine." Unfortunately I could not follow that instruction because ….
… the silver vinyl at the lab was not the material that could be used for heat transfer on fabric. So I had to get out and buy a sheet of heat transferable silver vinyl that I found here.
In the context of Fabricademy Bootcamp Paris 2017 I made a press-fit MDF scale model of a mannequin. Without going into details the end-to-end workflow (that could be used for a full scale version too) is described here in 6 steps., starting with: make a human in Makehuman and save as a mesh.
Assemble the model as per the Slicer instructions press fitting all parts in the right order in the right place. When done take a step backwards and admire your model. When using a larger lasercutter or a Shopbot this Makehuman - Fusion 360 - Slicer workflow can be used to make full size mannequins.
