Abstract

"PROCESSOS DE SINTERIZAçãO A LASER UTILIZANDO COMPOSIçõES TERMOPLáSTICAS". Trata-se de um método de sinterização a laser de uma composição termoplástica para proporcionar um artigo de fabricação que possui uma pluralidade de camadas sinterizadas. A composição termoplástica possui um ponto de fusão relativamente alto e um tamanho de partícula pequeno. os artigos de fabricação possuem uma alta resolução e excelente durabilidade e resistência.
