Chinese metal AM company BLT achieved revenue of around $170 million (USD) in FY 2023 making it by far the largest player by revenues in the APAC region and one of the largest in the world. The company’s financial performance in 2023 was significant if we compare it with generally slow sales by Western companies, with only EOS and SLM Solutions currently experiencing significant growth.

The $170 million in revenues represents a robust 34.24% increase compared to the previous year, as the company demonstrated its resilience and agility in navigating challenging market conditions. The net income attributed to shareholders witnessed a significant rise, soaring to approx. $19.6 million, marking a notable increase of 78.11% year-over-year.

Revenue breakdown by industries reveals a strong foothold in key sectors: Aerospace & Aviation comprising 56.02%, Industry with 37.32%, and Research Institutes contributing 5.64%. Revenue from customized 3D printing products, self-developed 3D printing equipment, and 3D printing raw materials saw significant increases of 34.45%, 26.46%, and an impressive 98.98% respectively compared to the prior year. This growth can be attributed to BLT’s continued emphasis on the aerospace sector, coupled with its proactive exploration of new markets and applications (Exchange Rate: 1 USD = 7.23 CNY, March 28, 2024).

A comprehensive metal AM solution provider

As of December 31, 2023, BLT boasted a workforce of 1,720 employees, with approximately 30% dedicated to research and development efforts. The company’s extensive infrastructure, comprising over 440 sets of additive manufacturing equipment, and over 120 sets of complementary analysis and testing equipment, solidified its position as the largest metal additive manufacturing industrial base in the world for a metal AM service provider.

At its core, BLT specializes in industrial-grade metal additive manufacturing, offering customers a comprehensive solution for their metal additive manufacturing needs. By utilizing its own metal additive manufacturing equipment, the company provides customers with design, production, and related technical services for customized metal 3D printed products, primarily applied in aerospace, industrial machinery, energy and power, research institutions, medical research, automotive manufacturing, and the electronics industry. Last year BLT produced 299 LPBF equipment and sold a total of 242 sets domestically and internationally.

BLT FY 2023 achievements

In 2023, metal additive manufacturing transitioned into a “mass production era,” reflecting the growing demand for batch production. BLT responded to this trend by making significant technological advancements, thereby contributing to the higher-quality evolution of the industrial manufacturing sector.

To meet the substantial demand from aerospace and aviation industries for large-scale metal additive manufacturing equipment suited to batch production, BLT introduced new platform solutions in 2023. These include the BLT-S615, BLT-S815, and the BLT-S1500, featuring 26 lasers and an extra-large format. The development of large-format equipment addresses the varied production requirements of aerospace customers, accommodating the manufacturing of both large and medium-sized components, as well as small-batch production of large components.

Efficient powder recycling is imperative for batch production in the “mass production era” of metal additive manufacturing. BLT has introduced diverse and efficient powder recycling solutions tailored to different production scenarios. For instance, multiple devices can be equipped with a production line-based powder recycling solution, while an integrated powder recycling solution can be provided for the continuous production of large equipment. These solutions not only significantly reduce production costs but also meet users’ demands for factory production line efficiency.

During FY 2023, BLT also unveiled several high-temperature alloys and titanium alloy materials tailored for the aerospace sector, leveraging the unique characteristics of metal additive manufacturing. Specifically designed for Laser Powder Bed Fusion (LPBF) processes, BLT introduced high-temperature alloy materials like BLT-In738, addressing challenges such as susceptibility to cracking and low density of formed parts during LPBF. These materials find applications in critical components like aerospace engines and gas turbines. BLT-Ti64 powder showcases remarkable mechanical properties and corrosion resistance, while BLT-Ti exhibits moderate mechanical characteristics, high plasticity, and excellent corrosion resistance, both suitable for aerospace and other industries. Furthermore, BLT-Ti2AlNb powder and BLT-Ti65 powder have surpassed the limitations of traditional titanium alloys, typically used below 600°C, and can now be employed in high-performance aerospace components. Additionally, BLT introduced BLT-TiAl4822 powder designed for Powder Metallurgy (PM) and Electron Beam Melting (EBM) processes. This innovation is anticipated to partially replace nickel-based high-temperature alloys, resulting in significant weight reduction for high-temperature structural components in aerospace engines.

Drawing upon its extensive industry chain advantages, the company has delved into innovations across equipment, powder, printing path planning, and process parameter adjustment. In 2023, BLT introduced the support-free technique, enabling the printing of structures with angles of less than 30° without the need for additional support. Since its introduction, this technique has been implemented in numerous industrial batch production processes, leading to decreased labor and energy consumption during post-processing procedures and ensuring efficient production cycles.

Finally, during FY 2023, BLT also established a software ecosystem tailored for a production line that could comprise over a hundred metal additive manufacturing machines.

BLT-BP V2.0, designed for the pre-processing stage, is compatible with the entire range of BLT equipment. It is tailored to fit BLT equipment packed with dozens of laser configurations, catering specifically to large-scale production scenarios such as shoe molds and electronics. It comes with customized high-efficiency parameter schemes to comprehensively enhance pre-processing efficiency.

The BLT-MCS equipment control software is highly tailored, boasting industry-specific modules for aerospace, engines, energy, automotive (including electric vehicles), electronics, molds, and scientific research. It caters to the needs of quality control, traceability, and efficiency enhancement in large-scale production settings. It continually refines functions like intelligent powder spreading, 3D reconstruction, visual correction, and automated integration.

The BLT-MES 2.0 production line management tool is tailored for large-scale production, drawing from the extensive experience in establishing production lines and analyzing data from hundreds of machines. It facilitates remote task deployment and seamless cross-process data tracing, effectively connecting the entire production workflow. The IoT module enables functionalities like data collection and real-time reporting, seamlessly integrates with third-party software, incorporates metal 3D printing processes into industrial manufacturing production, and lays the groundwork for an overall intelligence upgrade in the manufacturing sector, thereby driving down technical costs.
