“…Moreover, coupling photocatalysis cement technology with other newborn cement technologies is a crucial part of commercialization. For instance, one of the active areas of research in the field of 3D structural printing is to introduce functional cementitious materials to the printing process and to optimize the process parameters based on the incorporated multifunctional cementitious materials [208]. Investigating the efficiency of TiO 2 addition to other sustainable, environmentally friendly cementitious materials such as magnesium phosphate cement [209], cementitious materials based on the carbonation of fly ash, slags, and so on [210,211] could be considered as another environmental remediation for construction industry.…”

Applications of heterogeneous photocatalytic processes based on semiconductor particles in cement-based materials have received great attention in recent years to enhance the aesthetic durability of buildings and reducing global environmental pollution. Amongst all, titanium dioxide (TiO2) is the most widely used semiconductor particle in structural materials with photocatalytic activity because of its low cost, chemically stable nature, and absence of toxicity. Utilization of TiO2 in combination with cement-based materials would plunge the concentration of urban pollutants such as NOx. In fact, cementitious composites containing TiO2 have already found applications in self-cleaning buildings, antimicrobial surfaces, and air-purifying structures. This paper aims to present a comprehensive review on TiO2-based photocatalysis cement technology, its practical applications, and research gaps for further progression of cementitious materials with photocatalytic activity.

“…Although a few review papers on this topic can be referred to [34][35][36][37][38][39], this paper contains a much more detailed discussion on the fresh and hardened properties of 3D-printable cementitious materials, especially their definitions, experimental testing, and internally/externally effective factors. Section 2 covers the fresh properties, including flowability, extrudability, buildability, and open time.…”

3D-printing of cementitious materials is an innovative construction approach with which building elements can be constructed without the use of formwork. Despite potential benefits in the construction industry, it introduces various engineering challenges from the material point of view. This paper reviews the properties of extrusion-based 3D-printed cementitious materials in both fresh and hardened states. Four main properties of fresh-state printing materials are addressed: flowability, extrudability, buildability, and open time, along with hardened properties, including density, compressive strength, flexural strength, tensile bond strength, shrinkage, and cracking. Experimental testing and effective factors of each property are covered, and a mix design procedure is proposed. The main objective of this paper is to provide an overview of the recent development in 3D-printing of cementitious materials and to identify the research gaps that need further investigation.

“…Moreover, due to the growth projections of the AM, it is important to identify the needs that manufacturers will have to solve in the demands of quali ed personnel [4,38,39], more e cient printing equipment [40,41], materials with innovative characteristics [42][43][44], as well as the actions by e cient management of the FFF process [23,45,46]. Therefore, this article analyzes the growth and development of this technology, which, based on the information obtained, makes a projection about the growth of some aspects: manpower, materials, machinery, methods, and management, as well as the recommendations to solve these types of needs.…”

This paper discusses Fused Filament Fabrication (FFF) technology to know their evolution and trends, analyzing the materials, workforce, machinery, methods, and management been used. A literature review is done regarding FFF usage between 2010–2020. Data is analyzed for identify the countries that are applying this technology, the industrial sector, academic resources available and a curve is fitted to data for forecasting a trend until 2025. Projections indicate a growth of 300% for workforce in FFF usage for 2025, 280% for machinery, 312% for materials, 275% for the creation and modification of methods and, 320% growth for management activities.
