Additive manufacturing. A review of research, opportunities and challenges

3D printing, known as additive manufacturing, can change the construction industry for the better. Greater structural efficiency, lower material costs, increased accuracy and cost-effectiveness, all these characteristics are inherent in the additive manufacturing process. The article talks about a sharp increase in publications on the topic of additive manufacturing. 50% of them are suitable for use as a fine aggregate. They also considered ways to improve the properties of materials: strength, speed, hardening, moisture protection, etc. Additive manufacturing opens up many possibilities for construction, but new problems arise with this, with a greater emphasis on testing and stress testing and new design methods
