Shanghai Lunkuo Technology Co., Ltd., often referred to as Shanghai Lunkuo, is a privately held Chinese operating company. It serves as the parent company for the popular 3D printer brand, Bambu Lab. While specific revenue or employee figures are not publicly disclosed, reports indicate that its subsidiary Bambu Lab generates "very significant revenues," suggesting a substantial operational scale. The company is based in Shanghai, China, as implied by its name and involvement in local intellectual property disputes.
The company's primary operations are within the 3D printing industry. Through its Bambu Lab brand, Shanghai Lunkuo manufactures and sells a range of FDM 3D printers, including models such as the X1C, X1E, P1S, P1P, A1, and A1 mini. Additionally, Shanghai Lunkuo Technology Co., Ltd. develops and publishes the "Bambu Handy" mobile application, a 3D printing platform for managing printers and models, and operates the "MakerWorld" platform for sharing 3D print files. Its patent portfolio includes inventions related to 3D printing methods, waste material discharge devices, and print quality detection.
Shanghai Lunkuo Technology Co. exhibits a defensive patent litigation posture in the United States, with two tracked cases as a defendant and none as a plaintiff. Both cases, "Stratasys, Inc. v. Shanghai Lunkuo Technology Co. et al." and "Stratasys, Inc. v. Shenzhen Tuozhu Technology Co. Ltd. et al.", were filed in the U.S. District Court for the Eastern District of Texas, a venue known for its active patent litigation docket.
The notable U.S. cases stem from a larger patent infringement lawsuit initiated by Stratasys, Inc., a prominent 3D printing company. Stratasys alleges that Bambu Lab's 3D printers infringe upon multiple patents covering key FDM technologies, including heated build platforms, purge towers, and force detection mechanisms. Beyond U.S. patent disputes, Shanghai Lunkuo Technology, along with its affiliates, is also involved in copyright infringement litigation in China, particularly concerning user-uploaded models on its MakerWorld platform that relate to licensed intellectual property such as Ultraman.
