Welcome to the official news blog of Shenzhen Yanyun Magnetic Additive Technology Co., Ltd. (Yanyunmag), a metal 3D printing manufacturer headquartered in Shenzhen, China. In this space, we share the latest updates about magnetic 3D printing, educational deep dives into additive manufacturing, and practical guidance for engineers and procurement teams. Today's edition brings an exciting product announcement, a closer look at our proprietary technology, and a refresher on the fundamentals of magnetic additive manufacturing. We will also explore the often-underestimated role of post processing in turning raw printed parts into production-ready components. Whether you are an experienced AM professional or just starting to evaluate metal 3D printing for magnetic applications, this article is designed to give you comprehensive, actionable information. Read on to discover what our newest magnetic material can do for your next project.

Yanyun Tech is proud to announce the launch of its latest magnetic material formulation, a next-generation soft magnetic alloy developed specifically for laser powder bed fusion. This new material builds on years of research into magnetic 3D printing and directly addresses the two biggest complaints we heard from customers: inconsistent magnetic performance and difficult printability. Early beta tests show that parts produced with the new alloy achieve markedly higher saturation flux density and lower core losses compared with earlier generations. Equally important, the powder has been engineered to flow smoothly through the recoater of our SLM machines, which dramatically reduces print failures. The result is a material that lets engineers stop worrying about the machine and start focusing on the magnetic circuit design. For detailed specifications and a full datasheet, we encourage you to explore our 3D Printing Services page.

The headline features of the new material can be summarized in four words: high magnetic performance, enhanced printability. On the performance side, the alloy delivers a high maximum flux density and excellent permeability across a wide frequency range, which makes it suitable for demanding electromagnetic applications. On the processability side, the powder exhibits a narrow particle size distribution, low oxygen pickup, and excellent bed density, all of which contribute to stable and repeatable builds. Thermal management is also improved, because the material's composition reduces the residual stress accumulation that often causes warping in thin magnetic cores. Customers who have already tested the material report that they can produce thin-walled structures down to a fraction of a millimeter without sacrificing magnetic continuity. This combination of performance and processability is precisely what the market has been waiting for, and we are excited to finally bring it to production.

The application potential of this new magnetic material spans several high-growth industries, including electronics, motors, and sensors. In consumer and industrial electronics, engineers can now print compact inductors, transformers, and magnetic shielding components with complex internal geometries that would be impossible to machine. In electric motor design, the material supports the production of stators, rotors, and pole pieces with optimized flux paths, which improves torque density and efficiency. Sensor manufacturers benefit from the ability to integrate magnetic flux concentrators directly into housings and mechanical parts, reducing assembly steps and tolerance stack-ups. Because the material is fully compatible with our SLM equipment, customers can move from prototype to serial production on the same platform.

Behind every successful magnetic 3D printing project stands a mature technology stack, and Yanyunmag has spent more than a decade building one of the most complete stacks in the industry. Our proprietary technology combines high-precision SLM (selective laser melting) platforms with dedicated process parameters developed specifically for magnetic alloys. Unlike generic metal printers, our machines are tuned to handle the thermal behavior of magnetic materials, including careful melt pool control to avoid unwanted phase changes during solidification. This attention to detail means that printed parts retain their magnetic properties after printing, so customers do not have to sacrifice performance for geometric freedom. We also offer a full range of 3D Printing Equipment, from the compact YYC-M120 for research labs to the large-format M400 for industrial production. Every machine shares the same control architecture, which makes it easy to scale a validated process from research and development to the factory floor.

Compared with traditional manufacturing methods such as stamping, laminating, and machining, magnetic additive manufacturing offers several clear advantages that are worth spelling out. First, additive manufacturing eliminates the need for expensive tooling and dies, which means that design changes can be made overnight instead of over the course of months. Second, printed magnetic parts can feature three-dimensional flux paths, whereas laminated stacks are inherently limited to planar designs. Third, the process reduces material waste dramatically, because powder that is not consolidated during the build can be sieved and reused. Fourth, additive manufacturing enables the consolidation of multiple components into a single part, removing fasteners, welds, and the associated failure modes. These benefits are not just theoretical; our Case Application page shows a real aerospace example where a copper alloy rocket engine combustion chamber was printed with geometries that no casting process could replicate.

Magnetic additive manufacturing is the process of building three-dimensional magnetic components layer by layer from magnetic powders, most commonly using laser powder bed fusion technology. The process begins with a digital CAD model that is sliced into thin cross-sections, typically between 20 and 60 micrometers thick. A recoater spreads a thin layer of magnetic powder across the build platform, and a laser selectively melts the powder according to the slice data. The platform then drops by one layer thickness, a new layer of powder is spread, and the laser repeats the process until the part is complete. Because each layer is fully melted, the finished component is dense and strong, with magnetic properties that can be tuned through alloy composition and heat treatment. After printing, the
