3D Printing Technology Application Watch: Metal Lattices, Bio-inks, and Continuous Fibers — What Is Academia Actually Racing On? - Industry-Academia-Research
Metal powder bed fusion remains the dominant metal 3D printing route. On the equipment side, vendors are competing on parameters around multi-laser systems, large-format builds, copper alloys, and highly reflective materials, while research focuses on hard-demand scenarios such as lattice structures, point lattices, heat exchangers, and lightweight brackets. Some teams have integrated in-situ monitoring tools—acoustic emission, melt-pool radiation, and high-speed cameras—into the build chamber to enable early-stop intervention before interlayer lack-of-fusion evolves into an irreversible defect.
A printed metal part is only a semi-finished product; heat treatment, hot isostatic pressing, machining, and support removal each add cost, and the process window is narrow: too low a temperature leaves residual stress incompletely relieved, while too high a temperature causes grain growth and degraded properties. How to keep oxygen content stable after repeated powder reuse and how to control shape in multi-laser overlap zones are the real questions in equipment-process coordination. The continuous-fiber route, meanwhile, is tackling interface wetting, porosity control, and fiber orientation prediction, paired with topology optimization for small-batch validation of drone arms and robot links—but material databases lack allowable values, so structural engineers are reluctant to sign off.
For the metal additive manufacturing supply chain, the focus of competition has shifted from “getting the nozzle to move” to process-window repeatability, defect statistics and fatigue life, and standards and data traceability. Multi-laser large-format equipment, copper-alloy thermal management parts, medical implants, and superalloy components are clear landing points, but “print-and-done” remains marketing talk—post-processing and powder recycling determine whether batch production is possible.
Value for powder buyers: (1) Prioritize locking in powder suppliers with stable lot-to-lot oxygen content and traceable reuse cycles—don't just look at first-article inspection reports; (2) As demand for copper alloys and highly reflective materials picks up, confirm particle size distribution and laser compatibility with powder makers in advance; (3) Build powder recycling and replenishment ratios into cost models, and treat post-processing and quality traceability capabilities as hard criteria in supplier screening.

200 Million Yuan to Tap a Multi-Billion-Yuan Market: Southwest China's First High-End Spherical Copper Powder Production Line Awaits Investors
The Beidu Group of Qijiang High-Tech Zone in Chongqing has announced Southwest China's first high-end spherical copper powder production line project. The project plans to build a production line with an annual capacity of 2,000 tons of high-purity, micro-spherical 3D printing copper powder and copper alloy powder, supported by an ultrafine powder classification center and a precision testing laboratory. Upon reaching full capacity, it is expected to generate annual sales revenue of approximately 650 million yuan and annual profit of approximately 130 million yuan. With an investment of about 200 million yuan, the project aims to tap into the multi-billion-yuan spherical copper powder market, directly addressing the gap in large-scale precision 3D printing powder production in Southwest China.
The production line is positioned to produce high-purity, micro-spherical copper powder and copper alloy powder, with integrated classification and testing processes to form a closed-loop capability from powder preparation to particle size control. The site leverages local shale gas resources and preferential policies for gas-source areas. Phase I of a recycled copper project has already begun construction, with an annual output of 500,000 tons upon reaching full capacity, enabling nearby raw material supply and waste return, significantly reducing logistics costs. The dedicated railway line at Qijiang North Station on the Sichuan-Guizhou Railway has an annual transport capacity of 5.7 million tons, and the Sanhuan Expressway provides direct access, with all vehicle manufacturers within 100 kilometers, supporting both raw material input and finished product outbound transport.
Spherical copper powder, known for its electrical and thermal conductivity, is widely used in additive manufacturing applications such as high-end heat sinks, aerospace engine thrust chambers, electrical sensor components, and 5G communication base stations. The global compound annual growth rate of metal powders for additive manufacturing exceeds 25%, and the domestic spherical copper powder market is expected to reach tens of billions of yuan by 2027. Once operational, the production line will change the long-standing reliance on East China's coastal regions and imports for precision 3D printing powders, filling a critical raw material gap in the metal additive manufacturing supply chain in Southwest China.
Value for powder buyers: ① Monitor the ramp-up schedule of the 2,000-ton spherical copper powder and copper alloy powder capacity to secure regional supply share in advance; ② Leverage nearby recycled copper supply and dedicated railway logistics to reduce the overall cost of copper powder procurement; ③ Include the ultrafine powder classification center and precision testing laboratory in supplier audits to ensure batch-to-batch consistency in particle size and purity.

October 23, 2026 Titanium Market Daily: Titanium Product Prices Flat Across the Board vs. Yesterday
North Nonferrous Metals Network published its Titanium Market Daily on October 23, 2026, showing that titanium product prices were flat across the board compared with the previous trading day. That day, Longbai Group rose 2.05% intraday to RMB 14.46 per share, but the titanium dioxide sector index fell 1.42%, with 9 constituent stocks declining and only 1 advancing; Baoji Titanium dropped 2.56%. On the same day, Longbai Sichuan Titanium made public a new patent for a process to improve the hydrolysis rate of sulfate-process titanium dioxide.
On the industry side, Yongjin Co., Ltd.'s planned titanium material capacity is 100,000 t/yr, of which 35,000 t had been built by the end of H1 2026, accounting for about 17.5% of national titanium material output; its H1 titanium material output of 10,500 t already exceeded the full-year 2025 total. Titanium materials have achieved batch application in the 3C sector, and high-margin new products such as composite foil for VC vapor chambers are being commercialized at an accelerating pace. On October 21, the Nanzhao County Government and Jiangsu Hasen Intelligent Manufacturing signed a titanium metal powder manufacturing project, with Phase I investment of RMB 100 million, adopting processes such as plasma atomization; construction is planned to start in November and production in March next year, with annual revenue of more than RMB 300 million after reaching full capacity. At the market level, titanium concentrate and sponge titanium are approaching or falling below the cost line; high operating rates and high inventories mean the oversupply pattern remains unchanged, and production cuts are passive contractions. Demand is supported only by essential needs; titanium dioxide downstream users buy only as needed, chemical-grade titanium material orders are relatively weak, and the military and aerospace volume is insufficient to drive the overall market, with buyers and sellers locked in a standoff that has produced price stability at low trading volumes.
For the metal additive manufacturing supply chain, the standoff in sponge titanium and titanium concentrate prices near the cost line means the titanium powder raw material side lacks a clear directional signal in the short term; meanwhile, the landing of Hasen Intelligent Manufacturing's plasma-atomized titanium powder project points to continued expansion of domestic high-end spherical titanium powder supply capacity, and the batch adoption of titanium materials in consumer electronics applications such as 3C and VC vapor chambers is also opening non-aerospace incremental scenarios for additive manufacturing titanium powder.
Value to powder buyers: (1) Watch Hasen Intelligent Manufacturing's production start-up node in March next year and assess in advance the qualification window for plasma-atomized titanium powder as a second supply source; (2) with sponge titanium prices approaching the cost line, buyers can remain on the sidelines regarding long-term titanium powder contract prices and avoid locking in volumes at high levels; (3) track the pace of Yongjin Co., Ltd.'s titanium material ramp-up in 3C and VC vapor chambers to judge the demand elasticity of titanium powder for consumer electronics.
