Special Issue Information

Dear Colleagues,

This Special Issue is dedicated to 3D-printed materials and 3D printing technologies that can be included in a set of solutions in support of the environment, long-term environmental strategies for achieving sustainable development and the circular economy. In this Special Issue, we welcome articles providing an overview of the history of 3D printing or explaining how modern, ecofriendly ways of merging materials together layer by layer create objects from 3D model data.

According to the European Commission, additive manufacturing could save up to 90% of raw materials during manufacturing, reduce waste by nearly 90% and reduce energy use by 50% (the U.S. Department of Energy). However, both positive and negative impacts of 3D-printed materials and 3D printing technologies related to industrial sectors, health, consumer goods, energy, construction, etc., can be discussed in articles submitted to this Special Issue.

The significance of the reduction in different material technologies imposing negative impacts on people and the environment can be underlined in the context of 3D-printed “green” alternatives for materials. Articles concerning strategies for sustainably sourcing 3D printing materials from natural or waste sources and the development of 3D technologies for functional materials for a range of applications are encouraged. In particular, articles can focus on the lifetime cost to society, environment and economy plastic production has, which is set to double in 2050 (approximately USD 8.5 trillion ). With the world population projected to increase from 7.5 billion in 2017 to 9.8 billion in 2050, the next generation (within 33 years) is predicted to produce 12,000–13,000 Mt of plastic, while the yearly consumption is likely to reach 37–40 kilos of plastic per person worldwide. Therefore, articles presenting 3D-printed alternative plastic substitutions are welcome.

Finally, articles can offer a discussion to compare the numerous advantages with the many legal implications involved in the implementation and extension of 3D-printed materials and 3D printing technology.

All articles in this Special Issue are expected to create a collection of papers on the very hot topic of green technologies and man-made materials that are “greener”, thus, protecting the natural environment for future generations.

The intensive development of 3D Concrete Printing (3DCP) technology causes constantly increased its share in the construction sector. However, in order to produce products with controlled properties, optimization of the technological process is still required. Automation of production based on additive manufacturing methods streamlines the process by comprehensively manufacturing building components that meet, among others, strength, visual, and insulation requirements. Moreover, the possibility of using computer simulations to assess the properties of the designed elements allows for a multitude of analyzed versions of the constructed partitions, which can be verified at the design stage. Thanks to such an opportunity, the process of designing building elements can be significantly improved. The article presents results related to the assessment of the level of thermal insulation of products that can be produced by additive technology, depending on the applied spatial geometry of the vertical partition and the amount and type of materials used. Eight original solutions of in-fill pattern were designed, for which both Finite Element Method (FEM) computer simulations of thermal conductivity and experimental measurements of thermal conductivity of samples were performed. On the basis of the obtained results, both the correctness of the simulation results for the various analyzed materials and their consistency with the practical results were found. Depending on the investigated geometry, for samples of the same dimensions and using the same material, the differences in the U-factor obtained by FEM analysis amounted to 61%. The best solution from the investigated spatial geometries of the vertical partitions has been indicated. The U parameter in the variant with the best thermal insulation was 0.183 W/m2K, which meets the requirements of Polish construction law. The issues discussed in this work can be the basis for the selection of the best solution possible for practical use during the production of building walls using the 3DCP method fulfilling the guidelines of applicable standards. Furthermore, they can be used as a tool for optimizing geometry in terms of energy savings and reducing waste production by both engineers developing 3DCP technologies and architects using innovative techniques for manufacturing building structures.

Increasing concerns about global warming and its impact on the environment reinforce the need for new materials and technologies. Additive manufacturing has become more relevant due to its potential to build sustainable and more energy-efficient constructions. However, the materials employed within the technology are not yet fully sustainable. Researchers employing clay as the main binder have found that, besides protecting the environment, it benefits passive control of indoor temperature and relative humidity and contributes to comfort. The mortar design as well as the necessary technological adaptations for the 3D printing of earth mortars are addressed. From a material perspective, this paper reviewed and analyzed the recent developments in additive manufacturing of clay-based mortars, highlighting the main gaps and providing recommendations for future developments in this field.
