Projeto e construção de modelos moleculares flexíveis e modulares para impressão 3D

Abstract

This work arises from the concern about the lack of free-standing modular molecular models for 3D printing. Despite the commercial presence of molecular model kits, free molecular models, which allow their manufacture through 3D printing are not widely available. The present work studies the design and construction of a set of digital files that can be used for additive manipulation of molecular models with seven pieces (atoms and bonds) and a practical guide for printing the models. The customizable models allow the size adjustment of the pieces, are modular and flexible, allowing the construction of molecules in different spatial configurations, presenting low manufacturing cost and are adaptable to any 3D printer. The models available have good mechanical resistance during handling and allow the assembly of a set of organic molecules. We believe that the present work can contribute to the construction of didactic activities in which the application of molecular models can positively enhance the learning of abstract concepts such as molecular structure and isomerism.
