AcoustoFab: Contactless fabrication using acoustophoresis

我们在UCL的团队开发了一种称为声光多材料非接触式制造（AMCM）的技术，以解决困扰许多当前制造技术的几个问题，例如试剂、化学品、生物材料、食品和药品的污染和不安全处理。例如，工业和实验室在处理少量危险化学品或防止食品和药品污染方面经常面临困难。AMCM允许在3D空间中同时使用声音操纵技术（如传感器阵列和超材料）进行非接触式操作和制造多个物体（固体和液体）。这项技术在非接触式拾取和放置、清洁和3D打印中都有应用，它可以在3D空间中捕获物体，控制它们的移动性和速度。我们设想AMCM有潜力成为非接触式操作和制造领域的世界领先技术，我们建议在一个名为AcoustoFab系统的系统中使用AMCM，该系统可能会像3D打印机一样无处不在。

Our team at UCL has developed a technology called acoustophoretic multimaterial contactless manufacturing (AMCM) to address several problems that plague many current fabrication technologies, such as contamination and unsafe handling of reagents, chemicals, biomaterials, food, and medicine. For example, industries and labs often face difficulties in handling small amounts of hazardous chemicals or in preventing contamination of food and medicine. AMCM allows for the contactless manipulation and fabrication of multiple objects (both solid and liquid) simultaneously in 3D space, using sound manipulating technologies such as transducer arrays and metamaterials. This technology has applications in contactless pick and place, cleaning, and 3D printing, and it enables the trapping of objects in 3D space, providing control over their mobility and speed. We envision that AMCM has the potential to be a world-leading technology in the field of contactless manipulation and fabrication, and we are proposing the use of AMCM in a system called AcoustoFab Systems, which could potentially become as ubiquitous as 3D printers.
