Reactive Fusion (RF) is a novel Additive Manufacturing (3D Printing) process based on the principle of polymer powder deposition followed by the deposition of a monomeric / oligomeric fluid that infiltrates the powder layer and provides chemical bonding, between the deposited particles and the monomers/oligomers themselves, creating a continuous and homogenous material deposition. It has the potential to offer industry inkjet based 3D printing technique's processing speeds, combined with traditional polymer product production methods (moulding etc) levels of product strength and wide material choices. This process is similar to binder jetting based AM techniques and HP's multi-jet fusion system, however instead of using binders or fusion agents to melt the powder together, RF used a special ink to combine powder via chemical covalent bonding in order to achieve more homogeneous properties throughout a printed product.RF technology offers a patented, platform 3D printing process that removes the major current problem of AM polymer product delamination, and which prints products at high speed and low cost, delivers complex product structure capability and accesses the full properties of PU based polymers that is only currently available via traditional, long lead-time, expensive injection tooling and moulding.Our market research has shown the technology is of interest to multiple industrial sector with unmet AM product needs, several early technology adopters have been identified - potential markets include Automation/Robotics, Prosthetic/Orthotics, Dentistry, with further commercial interest evident in Automotive, Medical device, Footwear and the Sports industry sectors. We believe RF can displace a significant proportion of current traditional polyurethane product production, where use of AM is economical/feasible.Reactive Fusion Ltd has the expertise and drive to develop and commercialize its innovative RF technology in terms of chemistry, equipment and services based on several years of research from the University of Nottingham. The projects key objectives are to move the technology from lab scale, to industrial scale, creating product and process demonstrators for potential customers and early stage investors. Using subcontractors with extensive expertise in scaling up AM materials and building/modifying AM machinery/components, will support the project to achieve its goals with the resources proposed and with a managed level of risk.

反应融合 (RF) 是一种新型增材制造（3D 打印）工艺，基于聚合物粉末沉积原理，然后沉积单体/低聚物流体，渗透粉末层并在沉积颗粒和单体之间提供化学键合/低聚物本身，形成连续且均匀的材料沉积。它有潜力提供基于工业喷墨的 3D 打印技术的处理速度，结合传统聚合物产品生产方法（成型等）的产品强度水平和广泛的材料选择。该过程类似于基于粘合剂喷射的增材制造技术和惠普的多射流融合系统，但 RF 没有使用粘合剂或融合剂将粉末熔化在一起，而是使用特殊墨水通过化学共价键将粉末结合在一起，以获得更均匀的粉末。 RF 技术提供了一种获得专利的平台 3D 打印工艺，消除了目前 AM 聚合物产品分层的主要问题，并且可以高速、低成本地打印产品，提供复杂的产品结构能力并获得 AM 聚合物产品的全部性能。 PU 基聚合物目前只能通过传统、交货时间长、昂贵的注塑模具和成型来实现。我们的市场研究表明，该技术受到多个增材制造产品需求未满足的工业部门的兴趣，已经确定了一些早期技术采用者 - 潜在市场包括自动化/机器人、假肢/矫形器、牙科，汽车、医疗器械、鞋类和体育产业领域的商业兴趣明显。我们相信射频可以取代当前传统聚氨酯产品生产的很大一部分，其中使用增材制造是经济/可行的。Reactive Fusion Ltd 拥有专业知识和动力，可以在化学、设备和服务方面开发和商业化其创新射频技术，其基础是诺丁汉大学多年的研究。该项目的主要目标是将技术从实验室规模转移到工业规模，为潜在客户和早期投资者创建产品和工艺演示。使用在扩大增材制造材料规模和建造/修改增材制造机械/部件方面拥有丰富专业知识的分包商，将支持项目利用提议的资源和可控的风险水平实现其目标。
