ABSTRACT:
The need to generate models and prototypes quickly and efficiently highlights the importance of the development of 3D printers, due to its ability to manufacture complex designs with specific characteristics; however, despite the advances in this technology, the printing time using fused filament deposition technique (FDM) is still relatively long, Thus, this work focuses on the reduction of the total printing time, through the implementation of a process in which the printing tasks of a model are divided into several vertical sections that are joined layer by layer during the printing process. To achieve this task, the extruders have a relative movement between them so they print simultaneously each one of the sections of the model, to reduce the overall printing time considerably. In this work the consistency and strength of the joint formed between adjacent sections of the model evaluated to verify that the printed piece retains the mechanical properties similar to the piece built with a single extruder. This work evaluates the consistency and strength of the joints formed between adjacent sections of the printed model. PLA is the material used for the printed specimens following the ASME D638-14 spec.
