Additive manufacturing (AM) — more commonly known as 3D printing — is the practice of constructing objects using computer-aided drawings (CADs) and 3D printers to create materials that can be used in constructing buildings. The technology for AM is improving every day, with more printing methods and materials being developed for these types Despite the advantages and potential use of 3D printing in the construction sector, various factors can prohibit this technology from being mainstream. Given below are a few challenges of 3D printing technology in the industry: High costs. The high cost is the major challenge in the 3D printing industry. 1. Introduction. 3D printing construction technology was an amazing breakthrough in the past decade and potentially can revolutionize the construction industry, resolve residential crises, serve the green house, and brings in sustainability benefits, such as increased resource efficiency, improved construction productivity, compensates for shortages of skilled labors, and building of complex Benefits of 3D Printer: 1. Faster Speed. The biggest advantage of working with a 3D Printer is that they are very less time consuming in comparison to labour intensive approach. Not only they are concrete printing; concrete construction; geopolymer 1 Introduction Concrete is the most widely used construction material on this planet. aforementioned challenges. 3D printing technology is It is especially relevant in the residential construction environment of Malaysia, where a significant challenge has always been to reduce the waste of construction activities, which is ultimately susceptible to the effective relationship between 3D construction printing and the environmental production aspect of overall project success [34,45,68]. 3D printing has revolutionized various industries by enabling the production of complex designs and shapes. Recently, the potential of new materials in 3D printing has led to an exponential increase in the technology’s applications. However, despite these advancements, the technology still faces significant challenges, including high costs, low printing speeds, limited part sizes, and This critical review examines the developments and advances in 3D printing of concrete, as well as the challenges and future potential of this technology in sustainable construction. Our study highlights the advantages of 3D printing technology, such as reducing costs, materials, and time, enhancing safety, and minimizing environmental pollution. 3D printing trends in building and construction industry: a review. ABSTRACT Three-dimensional (3D) printing (also known as additive manufacturing) is an advanced manufacturing process that can produce complex shape geometries automatically from a 3D computer-aided design model without any tooling, dies and fixtures. 2. Additive manufacturing impacts the environment. The most popular material use for 3D printers is plastic filament. While this plastic is high quality and relatively inexpensive, its byproduct ends up in landfills. This practice contradicts our environmental movement to reduce our reliance on plastic. In order for widespread 3D printing to KwnS.
