Abstract


Filamentos de nanocompósitos de PLA com óxido de grafeno foram produzidos para aplicação em impressão 3D do tipo modelagem por fusão e deposição. As peças impressas com os nanocompósitos apresentaram melhores propriedades mecânicas se comparadas às peças impressas com PLA puro. As propriedades térmicas dos nanocompósitos não apresentaram alteração frente ao PLA. Foram avaliados também corpos de prova produzidos por injeção a fim de compará-los com aqueles obtidos por impressão 3D.
