3D Printing in Construction: Vision, Challenges

Abstract: 

Industry 4.0 represents the fourth industrial revolution, characterized by digital integration, automation, data analytics, and interconnected systems. In construction, this shift; known as Construction 4.0, leverages technologies like artificial intelligence, robotics, digital twins, and 3D printing to drive efficiency, precision, and sustainability in traditionally labor-intensive processes. Construction 4.0 has the potential to reshape the industry by addressing common challenges such as waste, inefficiency, and environmental impact while enhancing productivity, safety, and overall project quality.

Amid this shift, 3D printing emerges as a powerful tool in modern construction, offering precise material application, design flexibility, and faster project timelines. The presentation, titled "3D Printing in Construction: Vision, Challenges, and Barriers," will examine the growing role of 3D printing in transforming building processes to be more sustainable and cost-effective. By using 3D printing, construction projects can significantly reduce material waste, improve work conditions and safety, and reduce environmental impact.

Additionally, the presentation will explore the integration of Lean principles with 3D printing, demonstrating how Lean methodologies can further optimize resources, reduce unnecessary movement, and improve overall project performance. Real-world case studies will illustrate specific waste types in construction 3D printing, such as overproduction and excessive handling, and show how they can be effectively addressed through Lean strategies.

Finally, this presentation will discuss the challenges that 3D printing faces in construction, including material limitations, regulatory barriers, and scalability issues that hinder its wider adoption in large-scale projects. The presentation will examine how 3D printing can contribute to sustainable and efficient building practices and explore the obstacles that must be overcome for broader industry integration.
