Construction of an optimized 3D Printer, programmed by Arduino and designed in SolidWorks software

The 3D printer is a prototyping machine capable of producing three-dimensional objects, distributed in 3D software, which are built after layer through an additive process. This project aims to develop a low-cost open-source 3D Printer controlled by Arduino. It also aims to deepen the topic of rapid prototyping and provide the community, internal and external, of the Polytechnic Institute of Bragança (IPB), with a base for developing these printers so as to benefit from the study of new technologies and their replication. The most common and economical model, of a 3D printer, uses the technique of modeling by fusion and deposition (FDM - Fused Deposition Modeling), which is the base technology of our project. At the beginning of the project, we were proposed to design a 3D printer. In this there was the electronic/programming part already validated, with the need to build the mechanical part of it. Thus, we proposed to continue the base of the existing project, having carried out all the mechanical modeling of the printer and validating the design of the various parts that had to be raised in order to meet the various requirements this one demanded. There was also a survey of suppliers of various parts on the market from which an extensive list of references, suppliers, values, quantities, and forms of acquisition was drawn up. In order to make the final physical assembly possible, they were machined as aluminum parts, obtaining structural strength and reliability of the set. Aluminum parts were marked in order to able to use the “leftovers” existing in the mechanical workshop and thus manage to reduce and consolidate the final cost of the project.[3].
