“…In another project, Novi 3D print mechanism has been developed, which uses limestone wastes as the material for construction purposes to reduce the waste produced during construction (Biltcliffe, 2016). Application of stone sludge for 3D printing material purposes can bring lots of benefits in terms of waste reduction, reduction of shuttering, time and cost employed in construction and the overall promotion of automatic construction (Annappa et al, 2021). Xia and Sanjayan (2016) proposed a novel method for formulating geopolymer-based materials for the commercially available powder-based 3D printers' requirements.…”

Purpose In recent years, 3D printing technologies have been widely used in the construction industry. 3D printing in construction is very attractive because of its capability of process automation and the possibility of saving labor, waste materials, construction time and hazardous procedures for humans. Significant researches were conducted to identify the performance of the materials, while some researches focused on the development of novel techniques and methods, such as building information modeling. This paper aims to provide a detailed overview of the state-of-the-art of currently used 3D printing technologies in the construction areas and global acceptance in its applications. Design/methodology/approach The working principle of additive manufacturing in construction engineering (CE) is presented in terms of structural design, materials used and theoretical background of the leading technologies that are used to construct buildings and structures as well as their distinctive features. Findings The trends of 3D printing processes in CE are very promising, as well as the development of novel materials, will gain further momentum. The findings also indicate that the digital twin (DT) in construction technology would bring the industry a step forward toward achieving the goal of Industry 5.0. Originality/value This review highlights the prospects of digital manufacturing and the DT in construction engineering. It also indicates the future research direction of 3D printing in various constriction sectors.

“…The three-dimensional structure is built up layer by layer. Since that time, variants have emerged that are based on pellet-fed extruders [4] and those that process a fluid suspension to print ceramic and cement-based products [5], as well as hybrid systems, which print a metal powder in a polymer matrix, wherein the matrix is burnt away, leaving a metallic part [6].…”

Direct digital manufacturing consists of a set of techniques that enable products to be fabricated directly from their digital definition, without the use of complex tooling or moulds. This manufacturing approach streamlines prototyping and small-scale production, as well as the mass customization of parts with complex designs immediately fixed before fabrication. With broad applicability, there are clearly opportunities in the field of medical devices for its use. However, many of the developments of direct digital manufacturing focus on simply specifying the shape or the form of the product, and this limited scope throws away many of the particular advantages of direct digital manufacturing. This work is focused on remedying this situation so that the digital specification of the fabricated product includes the properties as well as the form of the product. We use in situ time-resolving small-angle X-ray scattering measurements performed at the ALBA Synchrotron Light Source in Barcelona to evaluate the control that can be exerted on the morphology of a semi-crystalline polymer during extruder-based 3D printing. We use this as a methodology for printing the patterns of the morphology of the polymer to realise the patterns of properties of the polymeric material, specifically the modulus of the polymer. We give an example of products produced in this manner that contain spatial variation in their properties.
