A impressão 3D, também conhecida como prototipagem rápida, é uma forma de tecnologia de fabricação aditiva onde um modelo tridimensional é criado por sucessivas camadas de material. Essa tecnologia vem crescendo a cada ano e já é uma tendência em empresas, escolas, hospitais e nas residências de entusiastas da área. Com esse tipo de impressão é possível criar coisas incríveis em diversas áreas do conhecimento.

Desde sua popularização e da facilidade de construção de produtos 3D, as suas vantagens e desvantagens estão sendo muito discutidas e apresentam um peso importante para a aquisição da impressora 3D de forma satisfatória.

ASPECTOS POSITIVOS E NEGATIVOS DA IMPRESSÃO 3D

Ao chegar às mãos de mais pessoas, novos e criativos usos para soluções de problemas foram surgindo. Em contrapartida, surgiram questões éticas que antes não eram consideradas. Assim como qualquer outro dispositivo tecnológico, a impressora 3D tem pontos positivos e negativos de acordo com a fabricação de seus projetos.

Imprimindo para o bem

Os aspectos positivos são inúmeros e extensos, desde a confecção de protótipos com alto nível de detalhamento, peças individualizadas e personalizadas, diversos tipos de materiais fabricado por uma única impressora, até a capacidade de solucionar pequenos problemas do cotidiano e salvar vidas através da sua facilidade de aplicação.

Usando uma impressora 3D, o carpinteiro Richard Van As, que perdeu 4 dedos da mão em um acidente de trabalho, e o designer Ivan Owen criaram um modelo de mãos robóticas que agarram objetos. Os dedos todos se movem de acordo com um comando dado pelo pulso do usuário da prótese. Caso seja dobrado para ‘fora’, os dedos se abrem; fechando o pulso para ‘dentro’, os dedos se fecham, segurando objetos e transformando a vida de crianças como Liam, de 5 anos, que nasceu sem os dedos da mão direita.

Imprimindo para o “mal”?

Da mesma forma que se constroem objetos para o bem, também são desenvolvidas iniciativas que podem gerar o mal. Uma pessoa mal intencionada pode utilizar a tecnologia 3D para fabricar armas, que utiliza balas de verdade. É possível imprimir todas as partes de uma arma e montá-la sem grandes dificuldades.

Outro projeto com aspectos negativos que também está sendo desenvolvido é a impressão de chaves a partir de uma imagem em alta definição, permitindo assim invasões a domicílios ou estabelecimentos quando fechados.

É preciso buscar por um equilíbrio, sabendo que a tecnologia que ajuda a melhorar e até a salvar vidas é a mesma capaz de produzir armas que acabam com outras vidas.
