Special Issue Information

Dear Colleagues,

Additive manufacturing technologies can drive a myriad of profound positive changes in the construction sector, namely those related to the digital transition. Expected benefits include, among others, material efficiency, improved safety and risk mitigation, greater quality control and design freedom, productivity improvements, and environmental gains. Therefore, fundamental and applied research covering the development of materials and technology suitable for digital transition in construction, as well as its application, is meaningful and necessary to fully understand the potential and technological boundaries of additive manufacturing in an array of different contexts, including architectural design, construction, rehabilitation, retrofitting, and maintenance of existing structures.

With this Special Issue of Materials entitled “Additive Manufacturing: Materials and Technologies for Digital Construction”, we invite the scientific community to report advances and novel insights on topics that may include, but are not limited to:

  • Advanced technologies for 3D digitalization;
  • Development, optimization, and characterization of eco-efficient printable materials;
  • Novel processing, reinforcement, and post-production methods;
  • Durability, deterioration mechanisms, and end-of-life valorization routes for 3D printed building materials;
  • Printable multifunctional materials and compatibility with traditional building materials;
  • AI/ML-based methods applied to development of printable materials and additive manufacturing processes;
  • Structural analysis, modelling, and topological optimization of additively manufactured materials and construction elements;
  • Using sensors for structural health monitoring of 3D-printed structures;
  • Life cycle analysis (LCA) and life cycle cost (LCC) of additively manufactured building materials and construction elements;
  • Integration of additive manufacturing into project management and building information modelling tools (BIM);
  • Novel business models and case studies.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Of the digital concrete-additive-manufacturing techniques, extrusion-based systems are probably the most widespread and studied. Despite the significant potential offered by 3D printing, several challenges must still be overcome. For instance, although several solutions have already been explored, the automated reinforcement of the layer-wise printed structures represents a challenge. The inline quality control of the fresh-state properties of 3D-printed materials is also an open question that needs to be addressed to find an efficient shared practice. This study proposes a new device designed to simultaneously reinforce 3D-printed structures along and through the layers and to be used as an inline quality-control device. This device consists in a sewing system, which is composed of a rotating system, and a hollow needle, which drives a reinforcing cable or yarn and can be used to inject cement grout to fill holes and improve bonding with reinforcement. The rotation is induced by a stepper motor, which measures the torque that is required to make the needle penetrate. This measurement can be used as a quality-control index to ensure material homogeneity. This paper aims to present an original reinforcement system that can be fully automated and simultaneously create reinforcement patterns in different directions of the printed structure while controlling the material’s fresh properties.
