When you think of Bambu Lab, you probably think of fast, reliable 3D printers — the A1, the P1S, the X1C. What you likely don’t picture is the company sitting across a courtroom table from the makers of one of China’s most viral toys.

Yet that’s exactly where things stand heading into April 2026. Pop Mart — the company behind the wildly popular Labubu character — has filed suit against Bambu Lab and its MakerWorld file-sharing platform, alleging that the platform enabled copyright infringement by hosting user-created knockoff 3D print files of the grinning, fuzzy dolls. The trial date is April 2nd.

This isn’t just a story about one toy brand chasing down counterfeit files. It’s a landmark case that asks a question the 3D printing world has never had to answer in court before: when users on your platform infringe IP, are you — the platform — liable?

What Is Labubu — and Why Does Pop Mart Care So Much About Fakes?

Labubu is a wide-eyed, pointy-toothed monster character created by Hong Kong–based 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. For a period, limited-edition Labubu figures were commanding two to three times their retail price on secondary markets.

The character is notable for being an entirely Chinese-owned intellectual property — and Chinese authorities have shown consistent enthusiasm for protecting it. Counterfeit physical Labubu toys have faced aggressive enforcement actions domestically, so it’s not surprising that Pop Mart would eventually turn its attention to 3D printable versions as well.

Pop Mart’s stock has been declining as Labubu’s hype cycle winds down. Industry analysts have noted that the company’s aggressive stance on counterfeits — even against comical 3D-printed versions — may be a strategic move to shore up the brand’s perceived exclusivity as it prepares to push its next character, Hirono, into the spotlight.

What Is MakerWorld and How Does It Fit Into the Bambu Lab Ecosystem?

MakerWorld is Bambu Lab’s official 3D model file-sharing community — roughly equivalent to Printables (Prusa’s platform) or Thingiverse, but tightly integrated with Bambu Studio software and Bambu Lab printers. Users upload print-ready files, and the platform handles discovery, ratings, remixes, and downloads.

For Bambu Lab, MakerWorld isn’t just a community perk — it’s a meaningful part of their product ecosystem. If you own a Bambu Lab A1 or a Bambu Lab A1 Mini, MakerWorld is where you go to find pre-sliced, one-click-print files optimized for your specific machine. That tight integration makes MakerWorld considerably stickier than generic file repositories — and also means Bambu Lab has more direct control over what’s on the platform than arms-length sites might claim.

A Timeline of Events: From Viral Toy to Courtroom

  Labubu goes viral globally

  Pop Mart’s Labubu blind-box toys explode in popularity across social media, driven by celebrity endorsements and limited-edition scarcity. A secondary resale market emerges almost immediately, with prices inflating significantly above retail.

  2023–2025

  3D printable knockoff files spread across platforms

  Fan-made and counterfeit Labubu models begin appearing across major 3D printing repositories worldwide — including MakerWorld, Printables, Thingiverse, Thangs, and Cults3D. Most treat them as harmless fan art in a long-standing gray area of maker culture.

  Pop Mart files suit against Bambu Lab in China

  Pop Mart names Bambu Lab and MakerWorld as defendants in a Chinese court, alleging the platform enabled IP infringement by hosting Labubu knockoff files. A trial date of April 2, 2026 is set. This marks the first time a 3D printing file platform — rather than an individual uploader — has been named as a defendant in this type of action.

  February–March 2026

  Bambu Lab removes all Labubu content from MakerWorld

  Bambu Lab executes a broad takedown of Labubu and Labubu-adjacent files. An automation error during the process causes dozens of completely unrelated user models — printer mods, cable clips, paint brush holders, locksmith tools — to be delisted alongside the targeted content.

  Bambu Lab apologizes; most models restored

  Following user complaints on Reddit and the MakerWorld Community Forum, Bambu Lab issues a public apology acknowledging the operational error and confirms most mistakenly removed models have been restored. Users with still-missing files are directed to submit support tickets.

  Trial begins in Chinese court

  The case proceeds. The outcome will set a precedent for how 3D printing platforms across China — and potentially globally — are expected to proactively police infringing content on their platforms.

How Did Bambu Lab Respond — and What Did They Get Wrong?

Bambu Lab moved quickly once the suit was filed, removing Labubu content from MakerWorld entirely. But the execution exposed a gap between the platform’s stated commitment to creator protection and its actual technical capabilities for targeted content removal.

The mass takedown swept up files that had nothing to do with Pop Mart’s IP. A locksmithing tool set, a collection of printer cable clips, paint brush holders, and other completely original user creations were pulled offline alongside the infringing models. The community reaction on Reddit and Bambu’s own forums was swift and vocal.

The irony here is pointed: Bambu Lab had, just weeks before, launched a Creator Copyright Protection Service — a tool specifically 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.

Why This Case Matters Far Beyond Labubu

The 3D printing community has operated for years under an informal understanding: fan art is fan art, nobody’s getting hurt, and takedown requests handle the edge cases. That framework has worked reasonably well in a world where platforms respond reactively to notices filed against specific files.

Pop Mart’s suit challenges that framework at the platform level. If the court rules that MakerWorld bears responsibility for what its users upload — rather than merely being obligated to remove infringing content once notified — it would introduce a proactive monitoring obligation that every 3D printing file platform in China would need to reckon with.

Western platforms — Printables, Thingiverse, Thangs, Cults3D — are watching closely. As of March 2026, Labubu knockoff models remain freely available on all of them. None have issued proactive takedowns. If the Chinese court establishes a platform-liability precedent, the pressure to act may eventually reach Western repositories as well, particularly as IP holders become more aware of their enforcement options.

What Does This Mean If You Own a Bambu Lab Printer?

Practically speaking — very little, right now. This lawsuit has no effect on Bambu Lab hardware, Bambu Studio software, firmware updates, or the company’s ability to sell and support printers. Your Bambu Lab A1, P1S, or any other machine will continue working exactly as before.

MakerWorld itself also continues operating normally — minus the Labubu content. For the vast majority of users who were downloading legitimate files, nothing has changed. The models that were accidentally caught in the mass takedown have largely been restored.

The longer-term implications depend entirely on the trial outcome:

• If Bambu Lab wins: The current reactive takedown model is validated. Platforms remove infringing content when notified; they’re not expected to proactively police uploads. MakerWorld continues as-is.
• If Pop Mart wins: Bambu Lab — and likely every other Chinese 3D printing platform — faces pressure to implement proactive content scanning and filtering. This could mean stricter upload reviews, automated model scanning, or restrictions on certain character-adjacent content categories.

Bambu Lab in 2026: Where the Printer Lineup Stands

Whatever happens in court, Bambu Lab’s position as the dominant force in consumer desktop 3D printing remains intact heading into 2026. Their printer lineup spans beginner-friendly open-frame machines to fully enclosed multi-material systems — and the MakerWorld ecosystem, despite this controversy, remains one of the best-integrated file libraries in the space.
