To determine the influence of fiber content and alignment on the mechanical properties of this novel material, a large number of standard test specimens were prepared, which included samples fabricated by mold-casting, randomly dispersed fiber reinforced mixtures and aligned fiber cement composites containing 10 types of fiber volume ratios manufactured by nozzle sizes ranging of 24 and 10 mm (fiber length = 12 mm). Mechanical properties and failure modes of the specimens under compression and flexural tests were studied experimentally. The anisotropic behaviors of printed samples were analyzed by different loading directions. As a result, the compressive and flexural strength of printed samples showed obvious anisotropy. With the increase of fiber volume ratio, flexural strength of the fiber reinforced composite was elevated tremendously but its compression strength reduced slightly. Moreover, fiber alignment also had a significant influence on the mechanical properties of the fiber reinforced composite. The composite cement-based material with 1 vol.-% aligned fiber exhibited an excellent flexural strength of 9.38 MPa, which increased by 483% in comparison to that of the plain cement paste.<\/jats:p>","DOI":"10.3390\/ma14092223","type":"journal-article","created":{"date-parts":[[2021,4,27]],"date-time":"2021-04-27T02:31:43Z","timestamp":1619490703000},"page":"2223","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Effect of Fiber Content and Alignment on the Mechanical Properties of 3D Printing Cementitious Composites"],"prefix":"10.3390","volume":"14","author":[{"given":"Hao","family":"Zhang","sequence":"first","affiliation":[{"name":"Institute of Steel and Spatial Structures, College of Civil Engineering &amp; Architecture, Henan University, Kaifeng 475004, China"}]},{"given":"Liming","family":"Zhu","sequence":"additional","affiliation":[{"name":"Institute of Steel and Spatial Structures, College of Civil Engineering &amp; Architecture, Henan University, Kaifeng 475004, China"}]},{"given":"Fan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute of Steel and Spatial Structures, College of Civil Engineering &amp; Architecture, Henan University, Kaifeng 475004, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5781-8765","authenticated-orcid":false,"given":"Mijia","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, North Dakota State University, Fargo, ND 58108-6050, USA"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Taylor, M., and Jay, S.
