Shenzhen Gongsan Technology consumer 3D printing factory ramps output ahead of China's 618 shopping festival, CEO Lin Zixiang details custom toy production

Shenzhen Gongsan Technology Co., Ltd. (Shenzhen Gongfu Sandi Technology Ltd.), a consumer-grade 3D printing service bureau based in Shenzhen, was featured during China's 618 shopping festival coverage for its scaled production of custom toys and decorative items. CEO Lin Zixiang and CTO Bian Zekun demonstrated the factory's operation of multiple material extrusion (FDM/FFF) printers producing items such as World Cup stress-relief soccer ornaments in anticipation of seasonal demand. The company operates a factory floor with dozens of FDM printers running in parallel, serving individual consumers and small businesses seeking low-volume, customized plastic parts without the overhead of owning a printer. The coverage positions Gongsan Technology as a representative of the growing Chinese consumer print-on-demand service segment, distinct from hardware OEMs like Bambu Lab that sell machines to consumers.

Gongsan Technology's featured role during 618 underscores the parallel expansion of two consumer AM business models in China: direct printer sales (led by Bambu Lab, Creality) and print-service fulfillment (Gongsan, JLCPCB's 3D printing division, and others). While Bambu Lab's flagship store in Shenzhen shows consumers buying machines for DIY use, Gongsan Technology operates a fleet-based model where consumers upload a file and receive finished parts, bypassing printer ownership entirely. This service bureau approach addresses the adoption bottleneck that many consumer FDM users face after initial enthusiasm - inconsistent print quality, material waste, and machine maintenance - by shifting production risk to a professional operator. The model aligns with the broader trend of service-based adoption in polymer AM, where the value accrues to the service provider who achieves fleet utilization above individual consumer rates.

From a market perspective, Gongsan Technology's 618 visibility confirms that Chinese consumer AM is bifurcating: hardware margins compress as OEMs compete on price and features, while service bureaus that invest in production reliability capture repeat revenue from consumers who value convenience over tinkering. The company must now demonstrate that its toy-and-decoration workflow can scale to higher-margin applications like small-series functional prototypes for local hardware startups or replacement parts for household goods. For buyers evaluating print-on-demand services, the key differentiator will be consistency of part quality across tens of thousands of orders, not the novelty of the production method itself.
