欧拉为金属增材制造运营商提供免费实时构建可见性

Icelandic software startup Euler has released Euler Viewer, a browser-based tool that gives metal 3D printing operators live visibility into their builds at no cost, with no hardware required. Each laser powder bed fusion (LPBF) build generates thousands of high-resolution images, one after every layer. Until now, that data has had nowhere useful to go. Operators running builds remotely have instead depended on remote desktop software connected to the 3D printer’s control PC, a machine that typically shares a factory network with proprietary build files and sensitive intellectual property. Euler Viewer is designed to make both practices unnecessary.

冰岛软件初创公司 Euler 发布了 Euler Viewer，这是一款基于浏览器的工具，可为金属 3D 打印运营商提供免费的实时构建可见性，无需任何硬件。每次激光粉末床熔融（LPBF）构建都会生成数千张高分辨率图像，每层一张。到目前为止，这些数据无处可用。远程运行构建的运营商转而依赖连接到 3D 打印机控制 PC 的远程桌面软件，而该 PC 通常与专有构建文件和敏感知识产权共享工厂网络。Euler Viewer 旨在使这两种做法都变得不必要。

The platform streams powder bed images directly to a browser as a build progresses, built on SOC 2 Type II security controls and requiring no connection to the printer’s control PC. Operators can move through a build layer by layer, share access with colleagues via a link, and for printers that cannot be connected directly, upload build data manually. Euler says setup takes minutes and the platform works with the vast majority of LPBF systems.

该平台在构建过程中将粉末床图像直接流式传输到浏览器，基于 SOC 2 Type II 安全控制构建，无需连接到打印机的控制 PC。运营商可以逐层浏览构建，通过链接与同事共享访问权限，对于无法直接连接的打印机，可以手动上传构建数据。Euler 表示设置只需几分钟，并且该平台适用于绝大多数 LPBF 系统。

According to the startup, Euler Viewer is free. The paid tier adds automated defect detection, predictive failure alerts, statistical process control, and automated build reports. Getting operators onto the free platform first is the cleaner path to selling them the rest. The company closed a €2 million seed round in November 2025, co-led by Frumtak Ventures and Kvanted, and holds several patent applications in real-time monitoring and failure prediction for additive manufacturing. Its platform has processed millions of build layers across customers in multiple countries.

据这家初创公司称，Euler Viewer 是免费的。付费层增加了自动缺陷检测、预测性故障警报、统计过程控制和自动构建报告。首先让运营商使用免费平台是向他们销售其余功能的更清晰途径。该公司于 2025 年 11 月完成了 200 万欧元的种子轮融资，由 Frumtak Ventures 和 Kvanted 共同领投，并拥有多项关于增材制造实时监控和故障预测的专利申请。其平台已处理了多个国家客户的数百万个构建层。

The wider significance is that build monitoring in metal AM has historically been the domain of expensive, hardware-dependent systems sold as premium add-ons. A software-only tool that requires nothing beyond a browser sets a different baseline for what basic process visibility should cost, and that has implications for how the rest of the monitoring market prices itself.

更广泛的意义在于，金属增材制造中的构建监控历来是昂贵、依赖硬件的系统的领域，这些系统作为高级附加组件出售。一个仅需浏览器、无需其他任何东西的纯软件工具为基本工艺可见性应花费的成本设定了不同的基准，这对监控市场其余部分如何定价具有影响。

Build monitoring in metal AM has typically required either dedicated hardware or a proprietary machine ecosystem to access. For instance, Phase3D’s Fringe Research software, developed with the US Air Force and NASA, measures anomalies during PBF builds and correlates them to defects such as porosity in the final part. The system depends on structured light hardware mounted to the printer, which means a facility has to procure and install additional equipment before any monitoring takes place.

金属增材制造中的构建监控通常需要专用硬件或专有机器生态系统才能访问。例如，Phase3D 的 Fringe Research 软件（与美国空军和 NASA 合作开发）可测量 PBF 构建过程中的异常，并将其与最终零件中的孔隙率等缺陷相关联。该系统依赖于安装在打印机上的结构光硬件，这意味着设施必须在进行任何监控之前采购和安装额外设备。

Elsewhere, Velo3D’s Assure software delivers real-time process and quality monitoring through in-built sensors and optics native to its Sapphire machines. That makes monitoring functional only for operators who have already bought into Velo3D’s hardware. Facilities running other LPBF systems have no equivalent access through that route.

其他方面，Velo3D 的 Assure 软件通过其 Sapphire 机器自带的内部传感器和光学器件提供实时工艺和质量监控。这使得监控仅对已购买 Velo3D 硬件的运营商有效。运行其他 LPBF 系统的设施无法通过该途径获得同等访问权限。

The constraint both tools share is that monitoring capability has been priced and packaged as a premium, available only after a procurement decision has already been made. Euler Viewer sits outside that model entirely by surfacing data that already exists inside the machines. Although, a technical distinction remains. Euler analyzes the 2D optical images provided by the machine’s internal cameras, while hardware-dependent systems like Phase3D use active sensors to generate 3D topographical measurements.

这两种工具的共同限制是，监控能力被定价并包装为高级功能，仅在做出采购决定后才可用。Euler Viewer 通过展示机器内部已有的数据完全脱离了这种模式。不过，仍存在技术上的区别。Euler 分析机器内部摄像头提供的 2D 光学图像，而像 Phase3D 这样依赖硬件的系统则使用有源传感器生成 3D 地形测量值。

For makers and professionals looking to explore metal AM or other additive technologies, having access to high-quality premium STL files is essential for successful prints. Whether you’re working with metal or polymer systems, the right 3D printing models can make all the difference in your project outcomes.
