The motivation is that mixtures with larger aggregate sizes offer benefits such as increased resistance to cracking, savings in other material components (such as Portland cement), and ultimately cost savings. Consequently, in the context of 3D Construction\/Concrete Print technology (3DCP), these materials are environmentally friendly, unlike the fine-grained mixtures previously utilized. Prior to printing, these limits must be established within the virtual environment\u2019s process parameters in order to reduce the amount of waste produced. This study extends the existing research in the field of large-scale 3DCP by employing coarse aggregate (crushed coarse river stone) with a maximum particle size of 8 mm. The research focuses on inverse material characterization, with the primary goal of determining the optimal combination of three monitored process parameters\u2014print speed, extrusion height, and extrusion width\u2014that will maximize buildability. Design Of Experiment was used to cover all possible variations and reduce the number of required simulations. In particular, the Box\u2014Behnken method was used for three factors and a central point. As a result, thirteen combinations of process parameters covering the area of interest were determined. Thirteen numerical simulations were conducted using the Abaqus software, and the outcomes were discussed.<\/jats:p>","DOI":"10.3390\/ma16093418","type":"journal-article","created":{"date-parts":[[2023,4,28]],"date-time":"2023-04-28T02:02:23Z","timestamp":1682647343000},"page":"3418","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["DoE Approach to Setting Input Parameters for Digital 3D Printing of Concrete for Coarse Aggregates up to 8 mm"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8415-4346","authenticated-orcid":false,"given":"Arno\u0161t","family":"Vespalec","sequence":"first","affiliation":[{"name":"Faculty of Mechanical Engineering, Institute of Machine and Industrial Design, Brno University of Technology, Technick\u00e1 2896\/2, 616 69 Brno, Czech Republic"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0493-5922","authenticated-orcid":false,"given":"Jan","family":"Podrou\u017eek","sequence":"additional","affiliation":[{"name":"Faculty of Civil Engineering, Institute of Computer Aided Engineering and Computer Science, Brno University of Technology, Veve\u0159\u00ed 331\/95, 602 00 Brno, Czech Republic"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5384-8668","authenticated-orcid":false,"given":"Daniel","family":"Koutn\u00fd","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Institute of Machine and Industrial Design, Brno University of Technology, Technick\u00e1 2896\/2, 616 69 Brno, Czech Republic"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"330","DOI":"10.1016\/j.jclepro.2017.04.002","article-title":"Potential benefits of digital fabrication for complex structures: Environmental assessment of a robotically fabricated concrete wall","volume":"154","author":"Hack","year":"2017","journal-title":"J.
