This Small Business Technology Transfer ( STTR) Phase II project will develop and commercialize a novel way to construct large, modular objects, such as concrete walls and components used in building a home, using a solid freeform fabrication process. The novelty of the proposed process is that is is capable of producing structures with wall thicknesses which are thickner than other similar methods. The structures can have contoured faces and alignment guides to permit quick assembly of layerwise construction. The proposed research will focus on aerated concrete as the structural materiaol, having proven the basic concept on structural foam in the Phase I research. The method is expected to result in rapid construction of homes with minimal labor and onsight assembly of pre-fabricated components. The broader impacts of this project, if successful, would represent a radical departure in a notoriously conservative industry, leading to the construction of inexpensive, pre-fabricated homes. The technology will address a significant market in the U.S. and developing countries to provide affordable homes to a very large population of low-income consumers. Other applications where this technique could be employed include construction of large objects such as boat hulls (pleasurecraft).

这个小企业技术转让（STTR）第二阶段项目将开发和商业化一种新的方式来建造大型模块化物体，如混凝土墙和用于建造房屋的组件，使用固体自由成型制造工艺。所提出的方法的新奇在于能够生产壁厚比其他类似方法更厚的结构。该结构可以具有轮廓面和对准引导件，以允许分层构造的快速组装。建议的研究将集中在加气混凝土作为结构材料，在第一阶段研究中已经证明了结构泡沫的基本概念。该方法有望以最少的劳动力和预制构件的现场组装快速建造房屋。该项目的更广泛影响，如果成功，将代表一个以保守著称的行业的彻底背离，导致廉价预制房屋的建设。该技术将面向美国和发展中国家的一个重要市场，为大量低收入消费者提供负担得起的住房。可以采用这种技术的其他应用包括建造大型物体，如船体（游艇）。
