3D printing construction start-upMighty Buildingshas raised $30 million在资金中，宣布现在正在退出隐形模式。
自2017年以来，该公司悄悄地对其专有的3D打印技术进行了研发，该公司现在正在以全面的“生产为服务”业务而启动。该公司的第一轮投资由Khosla Ventures，，，，with participation from venture capitalistsY组合者，，，，SV天使andcorevc。
Mighty Buildings使用了额外的资金来建立其奥克兰工厂并扩展其生产线，从而使其能够完全3D打印350平方英尺的单元。该公司还利用这项投资开始交付其混合动力产品（Part-3D印刷，部分传统构建），并继续扩展和商业化其技术。
Mighty Buildings的联合创始人Sam Ruben在与3D印刷行业的讲话中列出了他对公司的愿景。Ruben说：“我们的目标是为建筑行业启用设计与诺斯替代的生产。”“我们希望在世界各地建立强大的工厂，以使建筑商和建筑师能够以高效，成本效益，可持续性和风格的方式创建其设计。”
“We don’t actually aspire to be the ones designing and creating a set product line of housing units; we want to be the means that enables others to bring their vision to life.”
强大的建筑物从隐形模式退出
自2017年成立以来，总部位于加利福尼亚州奥克兰市的Mighty建筑物一直处于隐形模式。直到最近，该公司知之甚少，但现在已经揭示了其建筑3D打印技术，并以3,000万美元的投资回合。强大的建筑物的印刷过程是从头开始设计的，以扩展，并连续构建而不是建造一次性结构。
Building quickly but safely quickly became the firm’s top priority. Mighty Buildings gained UL 3401 certification, an important construction safety qualification, before exiting stealth mode. In fact, the Mighty Buildings was the first 3D printing construction business or product to become 3401 certified. The company also delivered two units to customers, and made sure that they met key certification requirements for their builds, before launching its platform in full.
“Once we had made significant progress against our certification roadmap, we felt ready to launch from stealth knowing that we could quickly scale up to the commercial level we originally envisioned for the business,” said Ruben. “Our goal is not to just produce our own units for customers, we want to be a production platform for industry to allow the existing labor force to build more.”
Mighty Buildings’ 3D printing method
强大的建筑物专有的3 d打印材料is central to its extrusion-based production technique. The company describes its stone-like minerals as “similar to Corian by Dupont,” an acrylic polymer used in the production of counter and bench tops. Uniquely, the material is able to harden almost immediately after UV post-curing, while still maintaining cohesion with its underlying layers.
轻量级材料的“冻结”能力使天花板和悬垂的能力无需任何基本的支撑结构。还可以使用机器人臂来完成后处理，从而导致加速，自动化的3D打印方法。一旦该公司完全自动化了其流程，它声称其技术比传统的现场建设便宜50％，并且比传统的预制方法便宜20-30％。
“Up until this point, most other companies working with 3D printing for construction have done projects through one-off permitting processes, which allows them to move quickly in the short-term but isn’t really scalable at a commercial level.”
相比之下，现有的构造3D打印方法使用水泥，因此无法自动进行后处理，并且承载结构需要钢筋。混凝土也是热导导的，这意味着通常添加其他绝缘材料以保持成品内部的温度。相比之下，强大的建筑物的类似corian的材料不太有利，使其更有效。
“最终,我们的目标是打印完整的壳啊f a house and then use robotic arms to pour insulation and apply finishes,” explained Ruben. “This will automate about 80 percent of the construction process, and the remainder (installing fixtures and appliances) will be done by humans.”
Safe as additive manufactured houses
Leveraging its proprietary additive manufacturing method, Mighty Buildings 3D printed a 350-square-foot ADU unit in less than 24 hours. The firm now plans to fabricate two hybrid buildings: one in San Ramon and the other in San Diego over the next year. Producing the structures in volumetric modules allows them to be customized too, and the tailor-made layouts present the opportunity for a range of applications from housing complexes to office buildings.
The company’s 3D printed houses reportedly cost 45 percent less to buy than traditional “stick-built” homes in California, and are 20 to 30 percent cheaper to build too.Mighty Buildings目前提供“强大的房屋套件”，价格从185,000美元到285,000美元，面积为865至1440英尺。将来，该公司的目标是将其技术的力量掌握在他人手中，使其能够建立更大，更进取的结构。
鲁本总结说：“我们希望允许建筑官员和其他人逐步对我们的技术感到满意，以帮助采用平稳的采用。”“就规模而言，实际上，我们受到过度运输的限制，而不是我们的印刷区。我们目前正在用具有新的纤维增强材料打印两层楼高的结构的能力，该材料具有与钢相当的强度，从而使我们最终能够创建多层建筑。”
建筑行业的3D打印
近年来，随着越来越多的公司推出自己的3D打印方法，并建造更雄心勃勃的建筑物，近年来，加性制造的住房行业越来越有竞争力。
