In 3D printing process using fused deposition modeling (FDM), filaments are used, including polylactic acid (PLA), coming from sugar cane or corn, which is melted during printing to form parts in three-dimensional layers. However, with the growing demand for 3D printing in different sectors of society, the trend is towards irregular disposal and the accumulation of this material in the form of waste. Therefore, we aim to reuse 3D printing waste made from PLA through mechanical recycling conversion. To this end, we held a 3D printing waste recycling workshop with High School and Higher students from the Instituto Federal do Amazonas Campus Manaus Distrito Industrial (IFAM CMDI). During the workshop, we asked students about 3D printing and sustainability and taught a class on the basics of 3D printing and recycling their waste. Later, the students used the single-screw extruder to form the PLA filament that can be used again in a new print. The students learned how to develop filaments for 3D printers, combining Environmental Education and Professional and Technological Education, stimulating learning and making them makers, manufacturing their own material, being able, in the long term, to undertake and work in this area. Therefore, with this PLA recycling workshop, we promote the circular economy, so that products and materials are reused, increasing their useful life and reducing waste. [ABSTRACT FROM AUTHOR]
