Technology & Products

Key Products

["SEBM (Selective Electron Beam Melting) Systems (e.g., Sailong-Y150, Sailong-S200, Y150 Plus)","PREP (Plasma Rotating Electrode Process) Powder Production Equipment","High-purity Spherical Metal Powders (Tantalum, Tungsten, Titanium alloys, Cobalt-Chrome)","3D-Printed Medical Implants (Tantalum and Titanium orthopedic units)","Titanium Alloy Orthopedic Implant Scale Additive Manufacturing Solutions","Customized Additive Manufacturing Technical Services"]

Technological Advantage

Vertical integration allows for total quality control over the material-to-part pipeline; their proprietary PREP technology produces powders with higher sphericity and purity than traditional atomization, while their EBM systems offer a domestic, cost-effective alternative to international competitors.

Differentiation

Value Proposition

Offers a complete closed-loop industrial chain—from proprietary powder production to high-end EBM hardware and finished parts—enabling the high-quality manufacturing of reactive and refractory metals at scale.

How They Differentiate

Vertical integration covering the entire value chain: proprietary Plasma Rotating Electrode Process (PREP) for high-purity spherical powder, in-house Selective Electron Beam Melting (SEBM) hardware, and clinical-grade medical implant production. This allows for superior quality control and cost-efficiency in processing reactive/refractory metals like Tantalum.

Recent coverage of Sailong Additive

Why this company matters

Sailong Additive occupies a distinctive position as China's leading vertically integrated specialist in Electron Beam Powder Bed Fusion (PBF-EB). Founded as a spin-off from the Northwest Institute for Nonferrous Metal Research, the company controls the full material-to-part pipeline: it produces high-purity spherical metal powders via its proprietary Plasma Rotating Electrode Process, designs and builds Selective Electron Beam Melting systems, and manufactures finished medical implants and aerospace components. This closed-loop model gives it quality control advantages over competitors that rely on third-party powders or machines.

The company's core technology centers on industrial-grade EBM systems—such as the Sailong-Y150 and Sailong-S200—optimized for processing reactive and refractory metals including Tantalum, Tungsten, and Titanium alloys in a vacuum environment. Its PREP powder production equipment yields powders with higher sphericity and purity than conventional gas atomization, a critical factor for repeatable EBM builds. Sailong also offers customized additive manufacturing services and scale production solutions for titanium alloy orthopedic implants.

Sailong's primary end markets are medical orthopedics and aerospace. It supplies Tantalum and Titanium implants to major Chinese clinical hospitals and works with AVIC, AECC, COMAC, and the China Academy of Launch Vehicle Technology on aerospace and defense applications. The company targets annual production of 300,000 orthopedic units by 2026 and reported 2024 revenue of approximately $11.8 million, with a 14.73% R&D reinvestment rate. It listed on the New Third Board in December 2024.

The company's main competitive challenge is GE Additive's Arcam EBM franchise, which dominates the global PBF-EB market. Sailong differentiates through vertical integration and a domestic cost structure, but it faces scaling risks as it pushes toward higher unit volumes. Its strategic affiliation with the Northwest Institute for Nonferrous Metal Research provides deep materials science backing, while financial support from Shaanxi Investment Group and Xi'an Investment Holding underpins its expansion. The open question is whether Sailong can replicate its domestic success in international markets where GE Additive's service network and brand recognition remain strong.
