Digital Micromirror Devices (DMDs) are the heart of the image-projection technology used in the modern cinema projectors. They are a 2D array of several million, micro-sized, computer-controllable mirrors, where each mirror can flip on its axis many thousands of times per second. When combined with a RGB light source, such as in a cinema, the device enables the projection of full-colour videos onto a screen. However, in recent years this projection technology has moved out of the cinema and into laboratories across the world, where it is assisting scientists in many research fields.At the Optoelectronics Research Centre, at the University of Southampton, scientists have been using this DMD technology to generate micron-sized intricate patterns of laser light, for the development of a range of novel subtractive (removing material) and additive (adding material) laser-based manufacturing processes. In this 5-year project, the team will be working with a wide range of industrial and academic partners, who see the potential for new and exciting manufacturing processes, as summarised below:SPI Lasers, a UK fibre laser company: A major advantage of using DMDs for shaping a laser beam is the extremely high speed at which light patterns can be generated, updated and modified. The team will be combining fibre laser technology with DMD technology to enable extremely high-repetition-rate beam shape and energy control, for applications in a wide range of manufacturing areas including the marking of high-value objects.M-Solv, a UK laser-integrator: Here, the team will be testing and optimising their technology using a wide range of industrial manufacturing lasers, and will develop a range of novel additive manufacturing processes for the micro-scale. The outcome will be additional manufacturing capability for UK companies.University Hospital Southampton: Recent scientific results have shown the ability to control the specialisation of human stem cells (e.g. to bone or to muscle) via intricately designed 2D surface structures. Working with Prof. Richard Oreffo, a founder of this field, the team will be using their technique to produce a range of bespoke surface-textured substrates that will enable biologists to further understand and control stem-cell specialisation for applications in regenerative medicine.University of Southampton: Metamaterials are a family of materials that offer amazingly unusual properties, such as the ability to bend light (for use as invisibility cloaks) or even slow it right down. However, scientists have yet to develop a cost-effective method for making such devices on centimetre or larger size-scales. The team will be investigating whether the DMDs combined with high-repetition-rate lasers can speed up the process and enable cost-effective manufacturing of cm-sized devices.Oxsensis, a UK company that develops sensors for extreme environments: The team intends to develop new manufacturing processes that will enable a new range of sensors for applications in industries such as Aerospace, Power Generation, and Oil and Gas. Specifically, the team will be using their recently demonstrated ability to laser-machine very accurately and rapidly in diamond, in order to develop new techniques for making sensors in a range of difficult-to-machine materials.

数字Micromirror设备（DMD）是现代电影投影仪中使用的图像预测技术的核心。它们是数百万个，微型，计算机控制的镜子的2D阵列，每个镜子可以每秒在其轴上翻转数千次。当与RGB光源（例如在电影院中）结合使用时，该设备可以将全彩视频投影到屏幕上。然而，近年来，这种投影技术已经从电影院中移出，进入了许多研究领域的科学家。在南安普敦大学的光电研究中心，科学家一直在使用这种DMD技术来生成微米大小的激光模式的激光模式，以开发出一种新型的材料（添加材料），并添加了新颖的材料（添加）（并添加）（并添加）（并添加）（并添加）（并添加）。在这个为期5年的项目中，团队将与各种工业和学术合作伙伴合作，他们看到了新的和令人兴奋的制造过程的潜力，如下所示：SPI Lasers，英国纤维激光公司：使用DMD来塑造激光束的主要优势是生成光速度的极高速度，可以生成，并且可以生成，并且可以生成，并且更新，更新，更新。该团队将将纤维激光技术与DMD技术相结合，以实现极高的高度重复率的光束形状和能量控制，用于在广泛的制造领域的应用，包括标记高价值对象。微尺度。结果将是英国公司的额外制造能力。南安普敦大学医院：最近的科学结果表明能够通过精心设计的2D表面结构来控制人类干细胞（例如骨骼或肌肉）的专业化。该团队将与该领域的创始人理查德·奥尔福（Richard Oreffo）合作，将使用他们的技术来生产一系列定制的表面纹理的底物，使生物学家能够进一步理解和控制STEM细胞专业化，以应用于再生医学。放慢速度。但是，科学家尚未开发一种具有成本效益的方法来以厘米或更大的尺寸制作此类设备。 The team will be investigating whether the DMDs combined with high-repetition-rate lasers can speed up the process and enable cost-effective manufacturing of cm-sized devices.Oxsensis, a UK company that develops sensors for extreme environments: The team intends to develop new manufacturing processes that will enable a new range of sensors for applications in industries such as Aerospace, Power Generation, and Oil and Gas.具体而言，该团队将使用他们最近证明的能力在钻石中非常准确，迅速地激光机器，以开发新技术，以制造一系列难以机理材料的传感器。
