Leijia Additive Technology

What Leijia Additive Technology does

Leijia Additive Technology (广东雷佳增材科技有限公司 / Laseradd) is a Chinese metal 3D printer OEM founded in January 2017 and headquartered in Zhuhai with additional operations in Guangzhou. The company designs, manufactures, and sells Selective Laser Melting (SLM) equipment across a full product spectrum spanning desktop precision (DiMetal-50, 100), mid-range industrial (DiMetal-280, 300, 150-series), and large-format industrial systems (DiMetal-450 series, DiMetal-650 with 625x625x1100mm build volume). Underlying technology is proprietary SLM using high-energy lasers to melt metal powder layer by layer, with a differentiated feature set including multi-laser scanning (achieving 80%+ efficiency improvement), multi-material simultaneous forming (1-4 materials), ultra-fine 20μm precision, a no-protective-gas variant for education, and self-developed control and path-planning software. The intellectual property base comprises 350+ SLM-related patents including 67 authorized invention patents with US and German grants, supported by 20+ years of foundational research led by Professor Yang Yongqiang of South China University of Technology dating to 2002.

The business model combines two revenue streams: (1) hardware sales of DiMetal equipment and additive-subtractive compound machines, distributed through direct enterprise sales, the 2022-acquired Kings 3D (金石三维) channel network, and trade show channels (TCT Asia, Medical Device exhibitions, Higher Education Expo); and (2) metal 3D printing processing services using titanium alloy, stainless steel, die steel, aluminum alloy, cobalt-chromium alloy, and precious metals for customers who need parts without purchasing equipment. Customers span six verticals — aerospace and defense (including Xi'an Aerospace Propulsion Research Institute), mold manufacturing, education and scientific research (including Guangzhou Technician College), medical, jewelry and luxury goods, and industrial/automotive — with 300+ cumulative customers across 10+ countries. Pricing is quote-based and not publicly disclosed; sales engagement runs through dedicated account managers, WeChat consultation, phone hotlines, and on-site demonstrations. Post-2022 the company operates as an independent brand under Kings 3D ownership, maintaining separate R&D, sales, and manufacturing functions.

Headcount is 51-100 employees with R&D technical staff exceeding 40%, reflecting an engineering-heavy organization anchored by the South China University of Technology founding team. The company is listed on Guangdong Equity Exchange's New Four Board (新四板) under code 892456 since July 2019, holds MIIT first-batch typical additive manufacturing application scenario recognition from 2022, and has received multiple industry awards including TCT Asia 2019 recognition. Recent strategic activity is concentrated in product portfolio expansion — eight new DiMetal variants launched between November 2025 and July 2026 — indicating active commercial scaling, while the absence of disclosed revenue or funding data limits external visibility into financial trajectory.
