Abstract

Thailand continues to face a shortage of housing, particularly for low-income populations who represent a vulnerable group requiring state support. Three-dimensional concrete printing (3DCP) has emerged as a technology adapted from plastic-based 3D printing used in small-scale applications. The development of concrete-based 3D printing began in the 1990s, followed by the introduction of “Contour Crafting” in 2004, which enabled construction application at full scale. In Thailand, 3DCP has since been used experimentally and commercially in material production and construction because printing material can be produced locally, making 3DCP a potential option to enhance design and construction efficiency to better meet public needs. Through field studies and post occupancy documentation of Baan Mankong projects, development for low-income housing initiatives in Thailand, due to its cooperative management structure that emphasizes community-building and induvial needs over commercial development, informed the need for improved housing design and construction processes. Analysis of standard house plans within the Baan Mankong program, including quantity surveying and pricing, to establish baseline materials and costs for design adaptation utilizing parametric design tools to assist with design and production process which improves 3DCP construction efficiency and assist home owners to create house that suits their specific needs and financial situation, build just what they need, a democratic approach to design and housing development. Further to the design experiments, the study of how cost effective and economy of scale aspects which needed to be achieved to make 3DCP a financially viable option for real world construction.
