China Factory Runs 5,000 3D Printers — Outputting 160,000 Parts Per Day

The World's Largest 3D Print Farm Just Got Bigger

Inside a sprawling workshop in Shenzhen, 5,000 3D printers hum around the clock, producing up to 160,000 parts per day. The facility, operated by Shenzhen Jinshi Huasu Technology Co., Ltd., is reportedly planning to double its count to 10,000 machines by the end of 2026.

The scale is unlike anything seen before in additive manufacturing. At 5,000 machines running conservative estimates of four parts per build plate every three hours, the operation outputs 160,000 parts continuously — without tooling changes or production line warm-ups. At 10,000 machines, weekly output would exceed 2 million parts from a single location.

From Holiday Ornaments to Industrial Components

The facility initially focused on consumer goods and holiday products — printing festive horse ornaments, good-luck signs, and zodiac decorations ahead of Chinese New Year. A recent order illustrated the practical implications: 40,000 desktop ornaments featuring a horse and the Chinese character fu (meaning fortune) were completed within one week, from idea to delivery.

Only 3D printing could meet that timeline, said Yang Shengwu, a technician at the facility who has been with the company since it operated just 500 machines two years ago.

But the business is shifting. As printing technology and materials improve, more clients are coming for custom industrial components, said company head Li Jian. They've been testing new product categories including shoes and even basketballs.

The Economics of Scale

The TikTok videos from the facility show thousands of Bambu Lab printers. At an estimated average cost of $500 per printer, a 10,000-machine fleet would represent roughly $10 million in investment — comparable to about 10 large polymer Powder Bed Fusion systems or a couple of injection-molding setups.

Materials costs are trending toward parity with injection-molding granules, making the economics increasingly compelling.

China's Additive Manufacturing Boom

The scale reflects a broader national trend. China's output of 3D printing equipment surged 52.5% in 2025, according to the National Bureau of Statistics. The country's additive manufacturing sector grew from 20.8 billion yuan ($2.86B) to 70 billion yuan ($9.64B) during the 14th Five-Year Plan period (2021-2025), per the Additive Manufacturing Alliance of China.

This is a glimpse into the future of high-volume distributed manufacturing — where thousands of desktop machines working in parallel can compete with traditional mass production methods.
