Este artigo apresenta uma revisão da literatura explorando o potencial da impressão 3D de concreto (3DCP) quando combinada com princípios biomiméticos. A revisão, realizada utilizando as bases de dados Science Direct e Scopus, destaca a capacidade de imitar estruturas naturais, permitindo a criação de designs inovadores e complexos, otimizando recursos e melhorando as propriedades estruturais. As principais descobertas focam na aplicação das estruturas de Bouligand, inspiradas na quitina dos crustáceos, que aumentam o desempenho mecânico e a tenacidade em compósitos cimentícios. Os estudos revelam avanços significativos na resistência à flexão e no desempenho ao impacto através de vários padrões e ângulos helicoidais. Apesar dos resultados promissores, permanecem desafios na complexidade dos materiais, barreiras econômicas e a variabilidade dos resultados mecânicos. A pesquisa contínua é crucial para desenvolver regras de design específicas e aproveitar plenamente as capacidades da 3DCP biomimética, abrindo caminho para uma construção mais eficiente, sustentável e resiliente.
