| Abstract | Now a days additive manufacturing, or more commonly known as 3D printing, is playing a significant role in manufacturing. Not only for small parts, 3D printing is now being used for printing mega structures like boats and houses. Although conventional 3D printing has many advantages compared with other manufacturing processes, it has three critical drawbacks which are the limitation of print volume, low efficiency and difficulties related to printing complex parts. Mobility and collaboration have been explored by the researchers to solve the print volume and efficiency related shortcomings whereas introducing 5 axis 3D printing can successfully address the issue of printing complex shapes. But the potential of collaboration among mobile 5 axis 3D printers has not been explored yet. This study aims to generate the core concept for increasing the scope of collaboration for printing complex objects using 5 axis mobile 3D printers. Part partitioning, task allocating and toolpath generating have been discussed in detail for formulating the concept. Task allocation remains the most important step for collaboration as the printing strategies are developed here. Also, collision avoidance plays a critical role for task allocation. For validating the concept, experiments have been carried out by the developed 5 axis mobile 3D printers with tilting rotating printhead. Several models have been printed using this concept and the printing time has been verified. Finally, the developed units show that using this concept can significantly save the total printing time for complex objects. It indicates that this concept can be used to print large scale complex objects in a shorter time in both indoor and outdoor scenarios. |
