3D printing of concrete structures has had a strong development in recent years, enhanced by the advantages it presents over traditional construction. However, it currently still has some limitations. One of those limitations is to incorporate the reinforcements into the automated 3D printing process. The objective of this work is to present a review of the methods that have been used so far to reinforce the structures. The different methods used will be presented focusing on the reinforcement by the use of fibers. The properties of the fibers, lengths, and percentages of the same used in the mixtures will be analyzed. The results of the different tests will be shown making a comparison between the values obtained from the tests carried out with the printed and molded materials. Finally, the increases in the results of the tests that these fibers provide with respect to the samples without them will be analyzed.

近年来，混凝土结构的 3D 打印有了强劲的发展，与传统建筑相比具有优势。但是，目前它仍然存在一些局限性。这些限制之一是将增强材料整合到自动化 3D 打印过程中。这项工作的目的是对迄今为止用于加固结构的方法进行回顾。将介绍所使用的不同方法，重点是使用纤维进行加固。将分析混合物中使用的纤维的特性、长度和百分比。将显示不同测试的结果，并对从印刷和模塑材料进行的测试中获得的值进行比较。最后，
