Desenvolvimento de estufa com baixo custo para secagem de filamentos de impressão 3D

Abstract

This work presents the development of a low-cost oven for drying 3D printer filaments. The project arose from the need to maintain the filaments in ideal conditions for printing, or in conditions similar to those delivered by the supplier, since these materials are hygroscopic and tend to absorb moisture from the air, which compromises print quality and can damage equipment. The project aims to be easy to produce and low-cost, considering the high value of commercial dryers available on the market, which support only a few filament spools and have a high cost. The oven to be developed uses accessible materials such as a styrofoam box to ensure thermal insulation, and a control system using an ESP32 microcontroller. Thus, it will have temperature and humidity control and a heat source with forced ventilation, ensuring homogeneous and efficient drying of the filaments. The results demonstrate that it is possible to build a functional, reliable, and easy-to-use oven, contributing practical solutions to the growing 3D printing market.
