Here’s the full scoop on 3D-printing problems, beginning with consumer-grade fused filament fabrication (FFF) 3D printing, which uses more robust materials than resin-based SLA and DLP 3D printing. Then, the industrial applications of 3D printing are examined, focusing on where they’re headed for manufacturing, construction, and beyond. Construction 3D printing is a real challenge, but 3D printing structures at an architectural scale tend to be more and more doable. A lot of new 3D printers are arriving on the market each year, always faster and more powerful. As we saw in our review of 2017, the industry seems to focus on large-scale 3D printers, especially for metal 3D printing. Abstract. The limitations of traditional construction methods can be addressed by 3D printing, a technology that prints structural buildings in layers, which reduces labor, construction time, wastage of material, and the overall cost of the structure. This paper presents a literature review of the state-of-the-art of construction using 3D printing technology. We present a definition and a The progress of three-dimension printing (3DP) technology provides a new idea for the researchers and engineers on the construction industry, which has the sample principle as a 2D printer and can stack the printed planes layer by layer to obtain a 3D design model. Previous studies have shown that construction with 3DP technology can reduce 30 Extruded 3D printing is currently a widely used 3D concrete printing technology, which not only accurately prints prefabricated components but also reduces the generation of construction waste. Aiming at the high shrinkage deformation and cracking issues during the solidification and hardening process of 3D printed cement-based materials. The article further discusses the new geometric possibilities with 3D printed formworks and their potential for making concrete construction more sustainable. In addition, the opportunities and challenges of 3D printed formworks are evaluated in the context of other traditional and digital fabrication tools. A synthetic classification in five Dyes used to color fabrics can also be major sources of water pollution. Plenty of water is needed for manufacturing textiles and fabrics. Air pollution is also a major concern in textile producing giants like China. 3D printing can address a lot of those issues. 3D printed fashion allows designers to innovate faster. With continued investment in research and development, 3D printing could become a more viable and accepted method of construction, transforming the way the industry is managed in remote, isolated .
