I. Overview of Industry Exchanges at the 2026 Hebei Provincial Society for Additive Manufacturing Annual Conference

The 2026 Annual Conference of the Hebei Provincial Society for Additive Manufacturing will bring together metal 3D‑printing companies, university materials research institutes, aerospace and new‑energy equipment manufacturers, and powder‑material suppliers from across the province. Centered on key topics such as the upgrading of Hebei’s additive‑manufacturing industry, lightweight alloy 3D printing, LPBF laser powder‑bed fusion technology, and the lightweighting of high‑end equipment, the event will feature keynote presentations, roundtable discussions, and supply‑demand matchmaking sessions, making it one of the most influential additive‑manufacturing industry forums in North China.

This year’s annual conference focuses on the development needs of new‑type productive forces, with a particular emphasis on addressing the key challenges hindering the industrialization of additive manufacturing for magnesium, aluminum, and titanium lightweight metals. The event covers five major mainstream lightweight‑application sectors— aerospace, low‑altitude aerial vehicles, humanoid robots, new‑energy vehicles, and biodegradable medical implants—and brings together numerous industry experts and technical leaders from leading companies in the value chain to share cutting‑edge research findings on advanced processes, powder‑quality control, and component‑performance optimization.

II. Key Highlights of the Special Presentation on Additive Manufacturing of Magnesium Alloys by Tangshan Weihao

As a Hebei-based company specializing in magnesium‑alloy 3D printing and custom manufacturing of metal additive‑manufactured components, Tangshan Weihao’s technical team delivered a dedicated technical presentation at the annual conference, comprehensively outlining an industrialization roadmap that spans the entire value chain—from magnesium powder materials to finished parts. The core content was organized into six key sections:

1. The Context of the Lightweight Industry Era Lightweighting is a key competitive metric for high-end equipment. As the lightest commercially available structural metal, magnesium alloy boasts a density of just 1.80 g/cm³ and excels in specific strength, vibration damping, electromagnetic shielding, and biocompatibility, making it well-suited to meet the weight‑reduction demands of eVTOL aircraft, drones, medical implants, and new‑energy vehicle casings. Laser powder bed fusion (LPBF) additive manufacturing represents the optimal process for mass‑producing complex magnesium alloy components.
2. Comparison of Main Additive Manufacturing Processes for Magnesium Alloys A comparative analysis of the four major metal additive manufacturing processes—LPBF, WAAM, LDED, and FSAM—demonstrates that LPBF, with its ±0.1 mm dimensional accuracy and low magnesium evaporation‑induced oxidation, represents one of the preferred approaches for fabricating precision components from magnesium alloys.
3. Bottlenecks in the Industrialization of Magnesium Alloy Additive Manufacturing In-depth analysis of industry-wide challenges: six major pain points—magnesium powder’s flammability and explosivity, high-temperature elemental evaporation, thermal cracking during printing, insufficient corrosion resistance, a narrow process window, and poor powder batch-to-batch consistency.
4. High-Quality Spherical Magnesium Powder Core Standard Powder directly determines the quality of printed parts. We explain the six critical performance metrics for additive‑manufacturing‑specific magnesium powders: high sphericity, narrow particle size distribution, low oxygen content, and excellent flowability. We also offer a comprehensive range of alloy powders, including Mg–Al–Zn, Mg–Re rare‑earth alloys, and Mg–Li lithium‑based alloys.
5. Innovative Additive Manufacturing Solutions for Magnesium Alloys It shares collaborative design approaches for topology optimization and deposition path planning, multi-beam–based temperature‑controlled printing, AI‑driven iterative optimization of process parameters, and magnesium‑alloy‑specific post‑processing strengthening techniques, all of which can effectively suppress printing‑induced cracking and enhance the overall mechanical performance of the components.
6. Standardization Development and Real-World Implementation Cases The team has participated in the development of multiple national and industry standards, including GB/T 44151-2024, “Magnesium and Magnesium Alloy Powders for Additive Manufacturing,” and showcased a range of mature printed components on site, such as magnesium alloy engine casings, integrated heat sinks, drone structural parts, medical porous scaffolds, and lightweight watch cases.

Following the sharing session, professors from participating universities, powder manufacturers, and equipment‑manufacturing companies engaged in in-depth discussions with the Tangshan Weihao team. They exchanged technical solutions on issues such as supporting the magnesium‑alloy additive manufacturing industry chain in Hebei, small‑batch flexible printing, end‑to‑end powder‑process control, and cost reduction and efficiency gains for lightweight components, while simultaneously aligning resources for industry–university–research collaboration and customized component procurement.
