This research study focuses on the use of 3-dimensional concrete printing (3DCP) to construct residential wall systems, including integration of windows and doors, wall penetration methods for utilities, and connections between roofs and foundations. The project drew evidence from interviews of home builders and contractors, visits to job sites, and a national survey of 305 homebuilders to understand challenges and opportunities in accelerating the adoption of 3DCP technology in residential buildings. The primary objectives include evaluating 3DCP wall systems' construction practices, identifying barriers to adoption, providing guidance to builders, and outlining steps to expedite the development of building codes and standards for 3DCP technology. An advisory group of key stakeholders reviewed 3DCP construction practices, technical requirements, and challenges, emphasizing critical considerations such as contracts, warranties, design options, building code compliance, and product installation.

This final report comprises a two-part primer document, offering an overview of the market potential for 3DCP technology and introducing construction practices. The research highlights consideration for builders, developers, architects, and design professionals in the context of designing buildings with 3DCP technology, contributing to a comprehensive understanding of the challenges and opportunities in the adoption of innovative construction methods.
