3D Printing is nothing more than reliable automation for hours, and sometimes even days. Whether it is FDM, SLA, DLP the main principles remain the same.
In the case of FDM 3D Printing the system is controlled by a set of motors, heaters, and switches. Nothing very complicated by itself, but when precise coordination is required complexity is added. Additionally, the flow characteristics and flow mechanics of various thermoplastics adds much more complexity in the realm of path planning.
Fortunately, systems that are required to operate with a high degree of precision and low failure-rate are ideal for tasks that could otherwise prove impossible using conventional tools. This is an example of using precision automated mechanical systems to enable a never before used attachment mode for 3D printed parts. More details to follow later.
