Reciclagem de polímeros na criação de insumo para impressoras 3D

Abstract

The disposal of polymers in domestic waste or as industrial waste is a factor that calls the attention of society due to its high volume. It is known that there are many ways to recycle such materials and one of the most innovative is through reuse in the 3D printing process, a rising technology in the world market, as it enables the manufacture of various products using polymers. This work studied how to generate plastic filament for 3D printers using one of the most easily found polymers in everyday life, PET. Equipment was developed to manufacture the filament from PET claws and the characteristics of this filament, such as flexibility and resistance, were studied. The results of the experiments were positive, achieving a filament with use of 80% of the initial raw material, presenting a lot of mechanical resistance. The filament produced is recommended for prototyping projects or low-cost products, as it is a absorbent filament of a simple production process.
