Elaboração de protocolo para confecção de dispositivo corretivo ocular customizado impresso 3D para crianças acometidas com microcefalia

Abstract

Objective: To develop a protocol for the materialization of eyeglass frames for children with Microcephaly, being developed using a software CAD (Computer-aided Design) and obtained by three-dimensional printing by Filament Deposition Modeling processing (FDM) using Thermoplastic Polyurethane (TPU) filament as material. Method: This is an applied and experimental investigation. Results and discussion: First of all, we present the main themes for the project proposal, information about Assistive Technologies and the development of additive manufacturing technologies applied to health. Furthermore, there is the presence of the procedure to be adopted in the project and the indication of the need for a Systematic Review and anthropometric survey of the children's head. In addition, it was necessary to develop a data collection with the anthropometric facial measurements of the children and submit them to the analysis with the intention of extracting the averages and thus create a 3D humanoid that was used as support in the development of the proposals, since thus, it was possible to develop some interaction tests with the device, even before being printed three-dimensionally. Then, after this creation, it was possible to go to the device development and protocol creation, where it counted on the use of free virtual modeling software, the use of 3D printers, as well as the post-finishing process. Subsequently, a test was carried out to validate the frame creation protocol with some designers, in order to improve it and mitigate possible failures. Finally, the eyepiece frame CAD file was freely available on digital platforms in order to be used in laboratories of the Unified Health System (SUS).
