The incremental material deposition allows organic shapes without formwork, a mandatory constraint in preparatory phases of conventional complex concrete structures. Nowadays, in three-dimensional printing for construction industry, concrete is the most used material due to its workability, extrudability, and pumpability properties favorable for the printing conditions. Hence, this composition still has a poor sustainable efficiency due to the high levels of Portland Cement. In this research, a reduction of this material was studied and experimented searching for a mortar composition with better ecological footprint, with the objective of decreasing the CO<jats:sub>2<\/jats:sub> emissions. A bibliometric analysis was made to study the constituents of a mortar for three-dimensional printing and respective dosage. The knowledge acquired in the analysis of the compositions contributed to the development of mortars with lower Portland Cement content. A mechanical extruder was used to check the extrusion capacity of the developed mortars, and the best compositions are presented. <\/jats:p>","DOI":"10.1177\/1464420721995210","type":"journal-article","created":{"date-parts":[[2021,3,3]],"date-time":"2021-03-03T05:59:01Z","timestamp":1614751141000},"page":"1419-1429","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Development of 3D printing sustainable mortars based on a bibliometric analysis"],"prefix":"10.1177","volume":"235","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3359-5157","authenticated-orcid":false,"given":"J","family":"Teixeira","sequence":"first","affiliation":[{"name":"CONSTRUCT, Faculty of Engineering (FEUP), University of Porto, Portugal"}]},{"given":"CO","family":"Schaefer","sequence":"additional","affiliation":[{"name":"School of Arts, Communication and Hospitality, Architecture and Urbanism, University of the Itajai Valley, Brazil"}]},{"given":"B","family":"Rangel","sequence":"additional","affiliation":[{"name":"CONSTRUCT, Faculty of Engineering (FEUP), University of Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9327-9092","authenticated-orcid":false,"given":"J Lino","family":"Alves","sequence":"additional","affiliation":[{"name":"INEGI\/Faculty of Engineering (FEUP), University of Porto, Portugal"}]},{"given":"L","family":"Maia","sequence":"additional","affiliation":[{"name":"CONSTRUCT, Faculty of Engineering (FEUP), University of Porto, Portugal"},{"name":"Faculty of Exact Sciences and Engineering, University of Madeira, Portugal"}]},{"given":"S","family":"Nunes","sequence":"additional","affiliation":[{"name":"CONSTRUCT, Faculty of Engineering (FEUP), University of Porto, Portugal"}]},{"given":"R","family":"Neto","sequence":"additional","affiliation":[{"name":"INEGI\/Faculty of Engineering (FEUP), University of Porto, Portugal"}]},{"given":"ML","family":"Lopes","sequence":"additional","affiliation":[{"name":"CONSTRUCT, Faculty of Engineering (FEUP), University of Porto, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2021,3,2]]},"reference":[{"unstructured":"McKinsey & Company.
