China's 3D Printing Market Had a Blockbuster Week: SUNLU IPO, Bambu Farm Dominance, and Metal AM Exports

China's 3D printing sector moved fast last week. A major materials supplier filed for IPO, the dominant consumer brand solidified its stranglehold on print farms, and metal AM machines started flooding export markets. Here is what actually happened.

SUNLU targets a $272 million IPO

SUNLU, one of the largest 3D printing material suppliers, had its IPO application accepted on June 22, 2026. The planned offering is valued at RMB 1.829 billion, roughly $272 million. The funds are earmarked for biodegradable 3D printing material production in Zhongshan and Wuhu.

That is a large bet on sustainable materials. SUNLU already sells PLA, PETG, TPU, and resin under its own name and the INSLOGIC sub-brand. An IPO at that size would make it one of the few pure-play material companies to go public outside of the major printer manufacturers.

Bambu Lab dominates print farms

Separately, Bambu Lab's grip on the prosumer and professional print-farm segment keeps tightening. Industry analysis shows the company has captured over 40% of the prosumer FDM market in under three years. Its A1 Combo and P2S systems are now the default recommendation for anyone starting a print farm.

The reason is straightforward: reliability, multicolor tool changing, and a mature software ecosystem. Bambu Lab's MakerWorld platform also hit 280,000 creators uploading models, with contributors averaging more than five designs each. That content flywheel makes the hardware stickier.

China's metal AM exports surge

On the industrial side, Chinese metal 3D printer exports are growing at a sharp clip. Lower prices, improved powder quality, and government backing for advanced manufacturing are all feeding the surge. Companies such as Rongsu Technology closed a CNY 100 million Series A+ round and launched consumer-priced metal printers, blurring the line between industrial and desktop metal AM.

Not everyone is cheering. US and European manufacturers now face direct price competition from machines that cost a fraction of domestic equivalents. The trade dynamic is shifting fast.

Why it matters

SUNLU's IPO, Bambu Lab's farm dominance, and the metal export wave are three sides of the same story: China is no longer just assembling low-cost printers. It is financing the supply chain, controlling the software layer, and exporting industrial-grade systems at scale. For buyers, that means lower prices and better tools. For Western competitors, it means a steeper climb.
