Esse post foi feito em 2011 e, depois de ver uma matéria na
Rede Globo, resolvi colocá-lo novamente no topo do blog.






POST ORIGINAL - 24/05/2011



Inspirado por um email encaminhado por meu amigo Silvio Smelstein, resolvi colocar esse post para divulgar um pouco mais sobre essa tecnologia.

Você já ouviu falar de impressoras 3D? Pois essas são impressoras que conseguem construir objetos com base em um modelo tridimensional. Na maioria dos casos o material utilizado para essa finalidade é o plástico. A maior aplicação desse tipo de equipamento é na indústria, para a confecção de protótipos ou auxiliar no desenvolvimento de projetos para novos produtos e equipamentos. As impressoras 3D podem até esculpir maquetes de edificações, transformando uma maquete eletrônica em um modelo real. 

Até pouco tempo o custo desses equipamentos inviabilizava a sua aquisição por instituições de ensino ou empresas de pequeno porte, dificultando também o acesso a estudantes ou profissionais interessados em realizar estudos com novas formas. Para as pessoas que sempre quiseram um equipamento como esse, agora existe uma alternativa de baixo custo! Um projeto chamado de RepRap tem uma proposta inovadora, oferecer uma impressora 3D de código aberto!

O nome RepRap é uma abreviação para Replicating Rapid-Prototyper, em uma tradução literal seria algo como Prototipagem Rápida Replicável! Mas o que isso quer dizer? Isso significa que essa é uma impressora 3D que pode se replicar! Então ela pode criar cópias dela mesma! Na verdade, como as peças da impressora são compostas de elementos de metal, plástico e madeira, a própria impressora 3D pode construir essas partes para a construção de um novo equipamento.

Na página do projeto existem instruções sobre como construir o equipamento detalhadamente, além do mais, todo o software que controla a impressora é Open Source. Então o custo para o equipamento fica resumido apenas à construção. Os custos também são muito atraentes, segundo as informações no site do projeto, construir uma impressora RepRap custa aproximadamente 400 dólares. Como os materiais selecionados para a construção são de baixo custo, o investimento geral será muito baixo se comparado aos equipamentos mais sofisticados.
