Wayland添加剂推出开拓性Neubeam驱动的Calibur3电子束3D打印机

经过18个月以上的预告片和开发,总部位于英国的3D打印机制造商Wayland添加剂终于启动了其第一个工业系统。

Calibur3具有该公司的新型Neubeam电子束熔化(EBM)技术,能够快速打印出比传统的电子束动力机器允许的更广泛的合金。由于该系统的中性电荷光束,它还能够以较高的密度制造大型物体,从而使工业采用者能够生产出更大的零件,而不必担心压力引起的故障。

韦兰德(Wayland)首席执行官威尔·理查森(Will Richardson)说:“韦兰团队的所有辛勤工作已经进入了流程的发展,并且这个新的硬件平台今天已经实现。”“现在,我们的使命是真正证明Calibur3可以为金属AM应用带来的差异。”

Stress-free metal 3D printing

Wayland has been working on its proprietary NeuBeam technology at its Huddersfield base since September 2019, when it received300万英镑的资金为其工业客户开发EBM系统。本质上,该公司的新颖过程旨在结合激光和EB方法的好处,以使用户能够进行更高的吞吐量金属3D打印。

在传统的EBM添加剂制造过程中,系统通常会积累导雷电竞充值致过热构建室的电荷,从而导致烟雾影响最终部分密度,这也降低了其与某些合金的兼容性。相比之下,Neubeam代表了一个“电荷中性”过程,这意味着它仅加热粉末床的部分,该部分目前正在打印零件。

As a result, partially-sintered powder is no longer an issue, post-processing is kept short and simple, and a wider range of metals can be processed without risking the production of low-porosity parts. Crucially, thanks to its neutral EB set-up, NeuBeam technology is also able to 3D print residual stress-free objects, potentially making it a highly-repeatable method of fabricating larger parts than are currently feasible.

Wayland’s Calibur3 launch

Initially, Wayland揭开了calibur32020年4月,从母公司获得了其Neubeam流程许可依赖精度。However, while the firm aimed to commercialize its new machine and fulfill six orders by the end of 2020, it was被迫推迟到一月2021年由于Covid-19限制,最终于2021年3月发布。

尽管Calibur3的全部规格尚未发布,但众所周知,它具有300 x 300 x 450毫米的构建量,与基于EB的类似系统相比,它提供了改进的能源消耗。在其他地方,Wayland新推出的金属3D打印机包括原位监测功能,这要归功于其集成的轻扫描,电子成像和红外摄像头模块。

Leveraging this captured imaging data, users are effectively able to monitor the temperature of the entire bed during processing, and intervene whenever topology defects are detected. The system’s cameras also provide end-to-end traceability, further contributing to its credentials as a 3D printing unit, that’s capable of repeatedly producing end-use-ready parts.

According to Peter Hansford, Wayland’s Director of Business Development, the Calibur 3 provides a “leap forward” compared to existing technologies. “Because it overcomes the compromises that most companies have to contend with when using metal AM, they can now revisit applications that were previously seen as troublesome and begin developing projects with a clearer view of the process,” explained Hansford.

他补充说:“ Calibur3系统和Neubeam流程提供了位于SLM和EBM系统之间的真实第三种方式。”“ Neubeam是一种金属添加剂制造过雷电竞充值程,可以从端到端节省时间和金钱,并且可以通过真正的生产伙伴关系使商​​业目标受益。”

现在,Wayland用新机器打破了封面,它打算在2021年5月19日举办一个更详细的亲自发布活动,那些有兴趣看到Calibur3 Close的人,CAN注册参加via the company’s website.

Shaking-up the EBM space

Despite the technology’s potential as a means of 3D printing high-strength parts, EBM is one of the industry’s less-common technologies. As a result, Wayland is entering a market that’s largely dominated by a small handful of companies such asGE及其ARCAM线of systems, that meet the vast majority of client demand.
