Abstract

Patente de Invenção: <B>"PROCESSO E MATERIAL PARA A PREPARAçãO DE CORPOS DE MODELO"<D>. Descreve-se um processo para a preparação de corpos de modelo, no qual, sob a aplicação de plásticos, especialmente de polímeros em pérolas escolhidos, pode ser construída uma estrutura tridimensional qualquer com auxílio da sinterização seletiva sob a utilização de luz de laser. Descreve-se, além disso, um material especial, que é especialmente adequado para a sinterização com laser. Como pós de plástico, utiliza-se um polímero em pérolas a partir de homo-ou de copolímero de compostos monoetilenicamente insaturados com um diâmetro de partícula médio de 2 até 200 Ám.
