Abstract

MÉTODO PARA IMPRESSÃO DE UM FILME TERMOPLÁSTICO EM UM MOLDE ÓPTICO. A presente divulgação se refere a um método de impressão de um filme termoplástico em um molde óptico compreendendo ajustar uma temperatura do molde óptico para uma primeira temperatura, imprimir uma primeira camada do filme termoplástico no molde óptico assim que a temperatura do molde óptico atingir a primeira temperatura, aplicar um vácuo ao molde óptico para manter o filme termoplástico no molde óptico, ajustar a temperatura do molde óptico para uma segunda temperatura, imprimir uma segunda camada do filme termoplástico na primeira camada do filme termoplástico assim que a temperatura do molde óptico atingir a segunda temperatura, ajustar a temperatura do molde óptico para uma terceira temperatura, recozer a primeira camada e a segunda camada assim que a temperatura do molde óptico atingir a terceira temperatura e remover o vácuo do molde óptico, permitindo a remoção do filme termoplástico, incluindo a primeira camada recozida e a segunda camada recozida, do molde óptico.
