Desenvolvimento de um sistema integrado de preparação e análise de grãos e sementes via impressão 3d para agricutura familiar

Abstract

The increasing demand for agricultural production in Brazil highlights the need for lowcost alternatives for seed quality analysis, especially for small farmers, justifying the development of this project. The objective was to build a portable device integrating a diaphanoscope and a grain divider using FDM 3D printing technology. The prototype was designed in SolidWorks, printed with PLA and ABS, assembled in the laboratory, and aimed at enabling visual analysis of mechanical seed damage and homogenization of seed samples; parameters such as light uniformity and sample division efficiency were established in the testing protocol. The equipment showed proper assembly, lightness, functionality, and a total cost of around R$ 700.00 — significantly lower than commercial equipment — with potential for identifying cracks and internal seed damage; however, practical performance tests have not yet been conducted. It is concluded that the prototype is ready for practical validation, and further testing with different seeds and environments is recommended.
