While many industries are using 3D printing to manufacture products, the technology has not been largely adopted in large-scale production.
.
According to researchers from the University of Arkansas Department of Industrial Engineering , this is mainly due to cycle time. However, while it’s possible to print different parts of one object at the same time thanks to multiple collaborating printheads, this isn’t yet widely supported by research.

Hieu Bui, Harry A. Pierson, Sarah G. Nurre, and Kelly M. Sullivan published a paper, titled “ Tool Path Planning Optimization for Multi-Tool Additive Manufacturing ,” that lays out their proposed toolpath optimization methodology. The abstract states, “The objectives are to create a collision-free infill toolpath for each printhead while maintaining the mechanical performance and geometric accuracy of the printed object. The methodology utilizes the combination of tabu search and novel collision detection and resolution algorithms, TS-CCR. The performance of the TS-CCR […]
