南美首批3D打印社会住房交付居民

Residents in La Unión, Antioquia, Colombia, have officially received the keys to their new homes, marking a historic milestone as the first 3D printed social housing project in South America. This pioneering initiative, led by construction 3D printing firm COBOD and cement company Cementos Argos, demonstrates how additive manufacturing can address critical housing shortages while reducing waste and construction time.

哥伦比亚安蒂奥基亚省拉乌尼翁的居民已正式收到新家钥匙，标志着南美洲首个3D打印社会保障性住房项目迎来历史性里程碑。这项由建筑3D打印公司COBOD与水泥企业Cementos Argos共同主导的开创性计划，展示了增材制造如何在减少浪费和缩短工期的同时应对严峻的住房短缺问题。

The two completed homes are part of the Casa Para Mí social housing program, run by Cementos Argos through its innovation unit, Future Tech. Key partners include Comfama, the municipality of La Unión, and contractor Fundación Berta Martínez. Each 63 m² unit features two bedrooms, a living room, kitchen, bathroom, laundry area, and a porch—offering families a complete, modern living space.

这两套已完工的住宅隶属于Cementos Argos通过其创新部门Future Tech运营的”我的家”社会保障性住房计划。主要合作方包括Comfama、拉乌尼翁市政府以及承包商Berta Martínez基金会。每套63平方米的单元配备两间卧室、客厅、厨房、浴室、洗衣区和门廊，为家庭提供完整的现代化生活空间。

COBOD supplied its BOD2 3D printer for the project, which printed all structural walls on site. The 3D printing process took just 16 hours, spread across three days, to reach a finished wall height of 2.2 meters. Compared to traditional construction methods, Cementos Argos reports a 30% reduction in build time, 20% less material consumption, and up to 30% less waste generation.

COBOD为本项目提供了BOD2 3D打印机，该设备在现场完成了所有结构墙体的打印。3D打印过程仅耗时16小时（分三天进行），最终墙体高度达到2.2米。据Cementos Argos报告，与传统施工方法相比，本项目的建造时间减少30%，材料消耗降低20%，废弃物产生量减少高达30%。

To achieve these results, Cementos Argos developed a custom mortar mix capable of withstanding the region’s seismic and climatic conditions. The mix achieved a compressive strength above 35 MPa and a flexural strength of 8 MPa. By incorporating calcined clay as a partial substitute for standard cement constituents, the team lowered the material’s carbon footprint without compromising structural performance.

为实现上述成果，Cementos Argos开发了定制砂浆配方，可承受该地区的地震和气候条件。该配方的抗压强度超过35兆帕，抗弯强度达8兆帕。通过使用煅烧粘土部分替代标准水泥成分，团队在保持结构性能的同时降低了材料碳足迹。

COBOD’s open-material strategy allowed the team to use this custom mix without any hardware modifications. Delivering the BOD2 printer to the remote, mountainous site required breaking it down across five small trucks and reassembling it on location. Despite humid tropical conditions and heavy rainfall, the team completed the 3D printing without any schedule interruptions.

COBOD的开放材料策略使团队无需修改硬件即可使用该定制配方。将BOD2打印机运抵偏远的山区现场需将其拆解装载至五辆小型卡车，并在现场重新组装。尽管面临潮湿的热带气候和强降雨，团队仍如期完成3D打印，未出现任何工期延误。

This project is part of a growing trend where 3D printing is used to address infrastructure deficits in challenging environments. In 2021, a similar COBOD BOD2 printer was used to build the world’s first 3D printed school in Malawi in just 18 hours, responding to a classroom deficit estimated at 36,000 by UNICEF. The parallel with La Unión is direct: both projects were driven by documented infrastructure gaps that conventional construction methods cannot quickly or affordably close.

该项目属于利用3D打印解决恶劣环境中基础设施缺口的日益增长趋势的一部分。2021年，类似的COBOD BOD2打印机在马拉维仅用18小时建成全球首所3D打印学校，回应了联合国儿童基金会估算的36000间教室缺口。拉乌尼翁项目与之直接呼应：两者均由传统施工方法无法快速或经济填补的既有基础设施缺口驱动。

Cementos Argos has already announced plans for further rural housing projects using the same method, with cost reduction at scale as the primary objective. As projects grow larger, the per-unit economics of construction 3D printing improve significantly, making it an increasingly viable solution for areas where conventional construction is slow, expensive, and logistically challenging.

Cementos Argos已宣布计划采用相同方法推进更多农村住房项目，主要目标是通过规模化降低成本。随着项目规模扩大，建筑3D打印的单位经济性将显著提升，使其日益成为传统施工缓慢、昂贵且物流困难地区的可行解决方案。
