The first requirement for this project is to create the mold by 3D printing. There are, typically, dozens of small parts that go into creating an actuator section. These can be divided up in to the upper and lower mold sections, then these can be broken down into three parts each. The main sections, where the body of the actuator forms a mechanical attachment, small segments of the actuator and then finally the thin divider that are the most important part of the actuator. The main and small segments can be printed fairly normally in whatever orientation best. The desire to be dimensional accurate is mostly important if using the exoskeleton for a gripping device.

The thin section require careful printer to be setup for best results. If this is done here then the other section will be inherently better anyway, so its worth doing. 

1. Make sure the bed is level, very level
2. The extruder height will give better results at the furthest distance from the bed possible which means when a piece of paper is just touching the extruder and bed.
3. As the bed and extruder are at the maximum distance the first layer will be difficult to bind to the bed. Slowing the first layer speed down to 5mm/s seems to work most of the time with a properly warm bed.
