Topological Optimization in 3D Concrete Printing Structures: A Review

Abstract

The deployment of additive manufacturing processes in the construction field has seen significant progress in the last decades. This progress has resulted in innovative techniques in architectural design and construction practices. These processes have benefits and constraints, primarily related to creating extra angle restrictions while printing complicated shapes such as curved concrete elements. The lightning of structures used in building objects is primordial in the reduction of environmental impact. We see the positive impact caused by shape optimization in saving material and making durable objects such as bridges and parametric architectural buildings. The combination of 3D-manufactured concrete and topology optimization allows the production of more performant and lightweight structural elements with no formwork and fewer workers. Many projects integrating shape optimization have been realized worldwide. In this article, we reviewed studies and projects that have explored the feasibility of using topology optimization and 3D printing technology to create complex, lightweight, and performant additively manufactured concrete structures with minimal material waste.
