Valoración en el uso de termoplásticos reciclados como una alternativa ambiental en la impresión 3D

Abstract

Abstract: This Degree Project is scientific and bibliographic in nature; It is part of the use of recycled thermoplastics for 3D printing, due to the fact that it is a technology that has increased notably in recent years and that from this it is possible to manufacture prototypes much faster. The 3D printing technology studied is the extrusion of the material where it uses the fused filament manufacturing technique (FFF), being the most used in recent years due to its hardware and free software. The thermoplastics used in the present investigation were high-density polyethylene (HDPE), polypropylene (PP) and polyethylene terephthalate (PET) together with a type of biodegradable polymer such as poly (lactic acid) (PLA), said materials are recycled obtained from an extrusion reprocessing. The mechanical and thermal properties were bibliographically analyzed in order to compile a wide range of their properties and to be able to select the best materials with good characteristics that are suitable for 3D printing.
