Desenvolvimento de impressora 3D com tecnologia Digital Light Processing (DLP).

Abstract

Additive Manufacturing or, as it is commonly known, 3D printing, refers to a manufacturing process through the successive addition of layered material in which information obtained directly from a (digital) 3D computational geometric representation is input of the object to be produced. The growing interest in using this manufacturing method to produce complex functional structures in three dimensions is due to its versatility and extensive application area, which is currently expanding, encompassing sectors related to medicine, electronics, chemistry, robotics etc. The goal of this work was to design and develop an additive manufacturing device (3D printer) using technology based on the principle of light curing through the digital projection of light from ultraviolet (UV) lamps, i.e. the Digital Processing of Light. Initially, definitions, technologies and the importance of additive manufacturing in different areas and applications are discussed. The sections are presented as follows: a bibliographic and technological review is presented, with details regarding the technologies chosen and used in this project; the development of the 3D printer is described in detail, referring to the design and construction of the device hardware, as well as the programming and configuration of the system control software; the results obtained and the details of the device’s operation; And finally, the conclusions of the work, with the main considerations after the completion of development, as well as improvements that can be made in future work.
