Shenzhen Tuozhu Technology Co., Ltd. (深圳拓竹科技有限公司) is a Chinese technology company headquartered in Shenzhen, Guangdong, China. Established in 2020, it operates as a privately held limited liability company. The company is notably the parent entity of Bambu Lab, a prominent brand in the consumer 3D printer market. Shenzhen Tuozhu Technology Co. reportedly has over 1,000 employees. Rumors suggest the company's annual revenue in 2024 was close to US$840 million, with a profit of US$280 million, and a valuation potentially reaching $10 billion with investment from Tencent.
The company's primary operations center on the design, development, and sale of 3D printers and related accessories under the Bambu Lab brand. Its product offerings include 3D printers, 3D printer filaments, automatic feeding systems, and other accessories. Beyond 3D printing hardware, Shenzhen Tuozhu Technology Co. engages in software development, electronics sales, research and development for intelligent robots and mechanical equipment, and provides Internet of Things (IoT) technology services. The company has also developed the "MakerWorld" 3D model sharing platform, which reported approximately 10 million monthly active users and 2.6 million original models by the end of 2025.
Shenzhen Tuozhu Technology Co. maintains a posture as an operating company defending its products in patent litigation. The company is currently involved in one tracked case as a defendant and has no cases as a plaintiff. This single case, Stratasys, Inc. v. Shanghai Lunkuo Technology Co. et al., was filed in 2024 in the U.S. District Court for the Eastern District of Texas, a venue known for patent litigation.
The case against Shenzhen Tuozhu Technology Co. (as a co-defendant with Shanghai Lunkuo Technology Co.) involves allegations from Stratasys, Inc., an industrial 3D printer OEM, that Bambu Lab's 3D printers infringe on ten of its patents, including one covering a heated build platform. Shenzhen Tuozhu Technology Co. has also been active in patenting its own innovations, such as a new 3D printer heatbed design, which has been discussed in the context of strengthening its legal position in the ongoing dispute with Stratasys.
