Impressora 3D por extrusão de forma livre para construção civil

Abstract

Currently, around 11 million Brazilians live in housing considered precarious according to a study carried out by the IBGE. Therefore, this work aims to develop a 3D printer project capable of printing house structures up to 38m² using mortar as a binding material. The development of this work includes selection and dimensioning of components for the assembly of the equipment. It is extremely important to develop a print head, where the mortar extrusion takes place, selection and sizing of mechanical components on the market that will provide the physical structure of the printer, as well as elements capable of promoting the movement and dynamic operation of the equipment. For this purpose, the work was mainly guided in the observation, understanding and operation of machines that have the same purpose. Making comparisons between movement mechanisms and subsequent selection of components, which are certified for use based on calculations of safety factors. The use of SolidWorks software was necessary só that the conceptual design and detailing of the equipment could be made possible.
