This paper aims to systematically develop and perform characterization of a commercially available ultra-high-performance concrete-class material (UHPC) modified to be printable. Four percentages of superplasticizer were used (100%, 94%, 88%, 82%) to adjust the UHPC mixture for 3D-printing requirements. A superplasticizer amount of 88% was considered adequate to meet the requirements. Several fresh and hardened properties of UHPC were measured experimentally: shape-retention ability and green strength were investigated in fresh state, and compressive and flexural strength were evaluated in three loading directions to evaluate the anisotropic effects. Furthermore, the strength of the interlayer bond was investigated. The UHPC developed in this study met the criteria for extrudability, buildability, and shape retention to ensure printability. In comparison with mold-cast UHPC, printed UHPC exhibited superior flexural performance (15\u201318%), but reduced compressive strength (32\u201356%). Finally, the results demonstrated that a commercially available UHPC-class material can be used for 3DCP, which possesses all necessary properties, both fresh and hardened.<\/jats:p>","DOI":"10.3390\/ma15186326","type":"journal-article","created":{"date-parts":[[2022,9,13]],"date-time":"2022-09-13T01:44:03Z","timestamp":1663033443000},"page":"6326","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Mechanical Performance of Commercially Available Premix UHPC-Based 3D Printable Concrete"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6423-9219","authenticated-orcid":false,"given":"Carolina","family":"Medicis","sequence":"first","affiliation":[{"name":"School of Engineering, Pontificia Universidad Javeriana, Bogot\u00e1 110231, Colombia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1689-0661","authenticated-orcid":false,"given":"Sergio","family":"Gonzalez","sequence":"additional","affiliation":[{"name":"School of Engineering, Pontificia Universidad Javeriana, Bogot\u00e1 110231, Colombia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1260-8211","authenticated-orcid":false,"given":"Yezid A.","family":"Alvarado","sequence":"additional","affiliation":[{"name":"School of Engineering, Pontificia Universidad Javeriana, Bogot\u00e1 110231, Colombia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3159-6997","authenticated-orcid":false,"given":"Hermes A.","family":"Vacca","sequence":"additional","affiliation":[{"name":"School of Engineering, Pontificia Universidad Javeriana, Bogot\u00e1 110231, Colombia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7828-6681","authenticated-orcid":false,"given":"Ivan F.","family":"Mondragon","sequence":"additional","affiliation":[{"name":"School of Engineering, Pontificia Universidad Javeriana, Bogot\u00e1 110231, Colombia"}]},{"given":"Rodolfo","family":"Garc\u00eda","sequence":"additional","affiliation":[{"name":"Enel Colombia, Bogot\u00e1 110221, Colombia"}]},{"given":"Giovanni","family":"Hernandez","sequence":"additional","affiliation":[{"name":"Enel Colombia, Bogot\u00e1 110221, Colombia"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"104039","DOI":"10.1016\/j.cemconcomp.2021.104039","article-title":"3D concrete printing of permanent formwork for concrete column construction","volume":"121","author":"Zhu","year":"2021","journal-title":"Cem.
