Sanlu Technology files for ChiNext IPO with 1.83 billion yuan plan; Bambu Lab sells 25,000 A2L and X2D units during 618 promotion

Sanlu Technology (三绿科技), a Chinese desktop FDM/FFF filament and printer manufacturer, has filed for a ChiNext IPO on the Shenzhen Stock Exchange, aiming to raise 1.83 billion yuan (approximately $253 million). Separately, Bambu Lab (拓竹), the Shenzhen-based consumer 3D printing leader, reported selling 25,000 units of its A2L and X2D models during the June 618 shopping festival, underscoring the rapid scaling of the Chinese desktop polymer AM market. Sanlu's filing includes plans to expand filament production capacity and develop new printer models, while Bambu Lab's sales figures confirm its dominant position in the high-speed, multi-material consumer segment.
These two events, while distinct, collectively illustrate the accelerating maturation of China's polymer AM ecosystem. Sanlu's IPO filing signals that the filament and entry-level printer segment is attracting serious capital market interest, moving beyond venture-stage hype into public-market infrastructure. Bambu Lab's 618 performance, meanwhile, demonstrates that consumer-grade FDM/FFF has transitioned from hobbyist novelty to mass-market electronics-like purchasing behavior, with 25,000 units sold in a single promotional window. This mirrors the pattern seen in the broader AM industry where desktop polymer segments, particularly in China, are growing faster than industrial metal systems, driven by localized supply chains, aggressive pricing, and social-commerce distribution. The competitive landscape now includes not only Bambu Lab and Sanlu but also Creality, Anycubic, and Elegoo, all vying for share in a market that is increasingly about brand loyalty, software integration, and after-sales service rather than raw hardware specs.
From a practical standpoint, Sanlu must demonstrate that its IPO proceeds will translate into consistent quality and supply-chain resilience, not just capacity expansion. Bambu Lab's challenge is sustaining this sales velocity without eroding margins or service quality as volumes scale. For buyers and investors, the key takeaway is that the Chinese desktop AM market is now a volume-driven, capital-intensive business where operational execution matters more than novel features. The next 12 months will test whether these companies can maintain growth while managing the post-sale support burden that comes with hundreds of thousands of installed machines.
