In this paper, we propose the use of a novel 3D printing cement-based composite material with natural, granulated cork, and additional reinforcement using a continuous polyethylene interlayer net combined with polypropylene fibre reinforcement. Our assessment of different physical and mechanical properties of the used materials during the 3D printing process and after curing verified the applicability of the new composite. The composite exhibited orthotropic properties, and the compressive toughness in the direction of layer stacking was lower than that perpendicular to it, by 29.8% without net reinforcement, 42.6% with net reinforcement, and 42.9% with net reinforcement and an additional freeze\u2013thaw test. The use of the polymer net as a continuous reinforcement led to decreased compressive toughness, lowering it on average by 38.5% for the stacking direction and 23.8% perpendicular to the stacking direction. However, the net reinforcement additionally lowered slumping and elephant\u2019s foot effects. Moreover, the net reinforcement added residual strength, which allowed for the continuous use of the composite material after the failure of the brittle material. Data obtained during the process can be used for further development and improvement of 3D-printable building materials.<\/jats:p>","DOI":"10.3390\/ma16124235","type":"journal-article","created":{"date-parts":[[2023,6,8]],"date-time":"2023-06-08T02:02:28Z","timestamp":1686189748000},"page":"4235","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["A 3D Printing Method of Cement-Based FGM Composites Containing Granulated Cork, Polypropylene Fibres, and a Polyethylene Net Interlayer"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4877-9135","authenticated-orcid":false,"given":"Daniel","family":"Pietras","sequence":"first","affiliation":[{"name":"Department of Solid Mechanics, Lublin University of Technology, Nadbystrzycka 40 Str., 20-618 Lublin, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6108-2992","authenticated-orcid":false,"given":"Wojciech","family":"Zbyszy\u0144ski","sequence":"additional","affiliation":[{"name":"Civil Engineering Laboratory, Lublin University of Technology, Nadbystrzycka 40 Str., 20-618 Lublin, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9212-8340","authenticated-orcid":false,"given":"Tomasz","family":"Sadowski","sequence":"additional","affiliation":[{"name":"Department of Solid Mechanics, Lublin University of Technology, Nadbystrzycka 40 Str., 20-618 Lublin, Poland"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"460","DOI":"10.1080\/17452759.2020.1818917","article-title":"Additive manufacturing of a shift block via laser powder bed fusion: The simultaneous utilisation of optimised topology and a lattice structure","volume":"15","author":"Kim","year":"2020","journal-title":"Virtual Phys.
