When Toy Giants Meet 3D Printing Platforms

In a case that could reshape the entire 3D printing ecosystem, Chinese toymaker Pop Mart has filed a landmark lawsuit against Bambu Lab’s MakerWorld platform over user-uploaded 3D print files of its wildly popular Labubu character. The trial, set for April 2, 2026, represents the first time a court will decide whether 3D printing file-sharing platforms bear responsibility for what their users upload.

For businesses in the custom 3D printing space — like ours at TT3DPrint — this case isn’t just industry gossip. It’s a potential turning point that could redefine how platforms, creators, and printing services handle intellectual property in the age of digital fabrication.

What Happened: The Labubu Files on MakerWorld

Labubu is a wide-eyed, pointy-toothed monster character created by Hong Kong artist Kasing Lung and commercially distributed by Pop Mart through their popular blind-box collectible format. The toys went genuinely viral around 2023, fueled by celebrity sightings and social media unboxing content, with limited-edition figures commanding two to three times their retail price on secondary markets.

On MakerWorld — Bambu Lab’s official 3D model file-sharing community — users had uploaded numerous 3D printable versions of Labubu figures. Pop Mart alleges these files constitute copyright infringement, arguing that the platform enabled the distribution of knockoff designs that compete directly with their official merchandise.

Bambu Lab responded by removing all Labubu-related content from MakerWorld. However, the mass takedown swept up completely unrelated files — a locksmithing tool set, printer cable clips, paint brush holders, and other original user creations were pulled offline alongside the infringing models. The community backlash on Reddit and Bambu’s own forums was swift and vocal.

Why This Case Matters for 3D Printing Services

The core legal question is simple but profound: when users on your platform infringe IP, are you — the platform — liable? This has massive implications for the entire 3D printing industry.

Platform liability vs. notice-and-takedown: The Western internet has operated for decades under the “notice-and-takedown” framework (Section 230 in the US, EU Digital Services Act). Platforms aren’t generally held responsible for user uploads — they just need to remove infringing content when notified. Pop Mart’s lawsuit challenges this model at the platform level. If the court rules that MakerWorld bears proactive responsibility for monitoring uploads, every 3D printing file platform worldwide would need to reckon with that precedent.

The irony of timing: Just weeks before the lawsuit was filed, Bambu Lab had launched a Creator Copyright Protection Service — a tool designed to help MakerWorld Exclusive Designers report their own files being stolen and redistributed elsewhere. The platform was actively building IP protection for its creators while simultaneously being sued for failing to protect someone else’s IP from its creators.

International ripple effects: Western platforms — Printables, Thingiverse, Thangs, Cults3D — are watching closely. As of early 2026, Labubu knockoff models remain freely available on all of them. If the Chinese court establishes a platform-liability precedent, the pressure to act may eventually reach Western repositories as well.

What This Means for Custom 3D Printing Businesses

For companies like TT3DPrint that specialize in custom FDM 3D printing, this case highlights several critical considerations:

• Design ownership verification: Services that accept custom orders must ensure clients own or have rights to the designs they submit. The Labubu case shows that even fan art and “tribute” designs can carry legal risk.
• Platform policy changes: If MakerWorld tightens IP enforcement, users may turn to external printing services to produce designs that can no longer be shared on official platforms. This could actually increase demand for custom printing services.
• Material and character licensing: The toy industry is watching this case closely. A ruling in Pop Mart’s favor could lead to stricter licensing requirements for 3D printed character merchandise — including figurines, collectibles, and custom toys.

At TT3DPrint, we’ve always prioritized working with original designs and respecting intellectual property. Our 220-printer Bambu Lab cluster is optimized for producing custom figurines, educational models, and creative products that our clients design themselves or commission from independent creators. We don’t produce knockoff merchandise, and we encourage our clients to do the same.

The Bigger Picture: 3D Printing Grows Up

This lawsuit is ultimately a sign of maturity for the 3D printing industry. When toymakers worth billions take notice of your platform, it means 3D printing has crossed from hobby to mainstream manufacturing. The challenge now is building IP frameworks that protect creators while preserving the open, collaborative spirit that makes the maker community thrive.

Pop Mart’s stock has been declining as Labubu’s hype cycle winds down, and industry analysts note that the company’s aggressive stance on counterfeits may be a strategic move to shore up the brand’s perceived exclusivity as it pushes its next character, Hirono, into the spotlight. But regardless of Pop Mart’s motivations, the legal precedent this case sets will affect every player in the 3D printing ecosystem.

For custom 3D printing services, the message is clear: original design is not just ethically right — it’s becoming legally essential. As platforms tighten enforcement and IP holders become more vigilant, businesses that build their reputation on legitimate, original creations will be best positioned for long-term success.
