The IP Risks of 3D Printing: Why Your Designs Aren’t Safe

IP risks of 3D printing include easy duplication of design files across devices, making proprietary data vulnerable.

3D printing is transforming the way we design, manufacture, and innovate, but it’s also opening a massive hole in the fence of intellectual property protection. At the heart of the problem is the digital nature of 3D printing: it runs on files that are easy to create, easy to copy, and incredibly hard to protect.

For industries that rely on proprietary designs, like healthcare, aerospace, and consumer goods, that’s a serious cybersecurity concern. Let’s look at how 3D printing puts IP at risk, the real-world consequences of those vulnerabilities, and what you can do to better protect your designs from digital theft.

3D Printing Has an IP Problem

3D printing is a process that relies on digital files, which fundamentally opens it up to security risks. The types of files primarily used in 3D printing are easy to share and easy to crack into. That makes it extremely difficult to protect IP.

The three most commonly used 3D printing files aren’t very secure:

Computer-Aided Design (CAD) files contain the original designs of objects used in 3D printing. If they’re unsecured, they can be stolen by hackers or competitors who want to replicate the designs.
Stereolithography (STL) files are also a widely used 3D printing format and they run a double risk: they’re not encrypted and they can be manipulated to embed hidden data or defects without altering the visible model.
G-code files translate models into specific instructions for printers, so any tampering with them can alter the printing process. Even the tiniest fraction of change can lead to defective or unsafe products.

Not only are these files un-secured and easily accessed, but the global, decentralized nature of 3D printing makes any IP standards hard to enforce. Even if designs or objects are copyrighted, it’s still too simple for malicious actors to steal them—and get away with it.

Top Cybersecurity Threats in 3D Printing

The biggest security threats in 3D printing are related to IP theft. Generally, when a cyberattacker launches some kind of attack on a 3D printing file, process, network, or the printer itself, it’s to steal data related to the design or object being printed.

The top IP concerns to worry about if you’re using 3D printers are:

Data interception and theft: When design files are sent or stored, they’re not usually very secure. They can easily be accessed, copied, and stolen.
Network security: Any 3D printers connected to networks for remote operations or cloud-based printing could be extremely vulnerable, especially if the networks aren’t properly secured.
File manipulation: Once an attacker gets access to a G-code file, they could potentially alter it, leading to unsafe or defective products.
Unauthorized production: If an attacker has stolen design files, they can easily use them to print products themselves, without the copyright-holder’s permission. This tactic could lead to reputational damage, if your proprietary products or processes are represented as someone else’s.
Side-channel attacks: This cyberattack is one of the sneakiest; it involves recording and analyzing signals like the acoustic sound, magnetic fields, or power consumption that come from the physical process of 3D printing. These signals can then be used to reconstruct the G-code or the object itself.

IP theft has far-reaching consequences when it comes to 3D printing and manufacturing. As we’ll see, critical industries like healthcare use 3D printers to create life-saving medical devices. If those designs get hacked and altered, it could be catastrophic for patients.

3D Printing Breaches: Examples

If you use a 3D printer for personal or business use, you should be fully aware of the security risks. The threat is very real, as these recent incidents show:

Anycubic 3D Printers

3D printer manufacturer Anycubic had a breach in 2024. Someone inserted a G-code file in their printers to prove that their security was lacking. Nothing bad happened to the affected users, it was just to make a point—which they definitely succeeded in making.

Hacking Sound Waves at UC Irvine

A group of researchers at the University of California Irvine were among the first to discover that you could hack into 3D printers using the acoustic sounds or magnetic fields they emit after conducting a study in 2016.

MakerBot and Thingiverse Breach

A data breach in 2021 exposed account credentials for Thingiverse, an online repository for sharing 3D printing models. It also affected the authentication tokens of MakerBot printers (MakerBot created Thingiverse in 2013). Since MakerBot printers have cameras, the breach allowed attackers to view printers’ video feeds.

Industries Most Vulnerable to 3D Printing Cyberattacks

Cyberattacks are a threat to any business or individual using 3D printers, but some industries are at a bigger risk than others. Manufacturing, critical infrastructure, and healthcare all stand to lose big when it comes to 3D printing.

Manufacturing

More and more companies use “additive manufacturing,” which basically means using 3D printing to build physical objects. Sectors like aerospace, automotive, and defense are particularly sensitive since they rely heavily on proprietary designs. The products and parts they produce also usually have safety-critical functions.

In 2016, a group of researchers showed that altering just a few lines of code in the 3D blueprint for a drone propeller caused the drone crash, less than two minutes after taking off. The changes were so slight you’d need a microscope to be able to see them when physically examining the propeller. Airplane parts could have the same weakness, if the designs were hacked and altered.

Critical Infrastructure

Utilities and transportation companies manage essential services, like electricity and public transit, so when components fail it creates widespread disruptions or even safety hazards. They’re also increasingly using Internet of Things (IoT) technologies, which rely on the cloud and remote access—adding another layer of vulnerability.

Healthcare

The healthcare sector could face major security issues with 3D printing as well. Printers are often used to create medical devices customized to specific patients. If a slightly altered propeller can cause a drone to crash, imagine what a tampered-with 3D-printed organ would do to a human body.

There are risks in healthcare that don’t come up as much in other sectors:

The embedding of malicious code in a medical device that’s only triggered in response to certain stimuli, causing the device to malfunction at a critical moment
Leaking sensitive patient data related to the 3D designs, violating HIPAA
Outdated or unsupported operating systems used by hospitals and medical devices that make them even more susceptible to attack
Lack of regulatory standards for 3D printing in healthcare—the laws haven’t caught up with the technology

Other industries like finance, pharmaceuticals, and energy can also be at risk because they work heavily with intellectual property.

Current IP Laws Fall Short

Current laws concerning intellectual property and 3D printing don’t provide enough protection to businesses or individuals. The scope of copyright, enforcement difficulties, and digital rights management (DRM) are all complications.

File sharing: 3D printing blueprints can easily be shared and replicated, making it difficult to control the dissemination of protected designs.
Ambiguous copyright protection: In the U.S., you can’t copyright 3D-printed objects considered “useful” but you can if they’re “artistic.” Many designs combine function with aesthetics, so it’s hard to decide if a design is eligible for copyright or not.
Patent enforcement: Anyone with a private 3D printer can replicate an object designed by someone else, even if the object is patented. There’s no way to tell when a patented invention has been replicated and printed, making enforcement nearly impossible.
Counterfeiting: Trademark laws aren’t necessarily clear on when an individual prints a trademarked product for personal use, and when it’s printed for commercial use. That opens the door for counterfeiting.
DRM systems: Licensing and DRM systems for digital design files haven’t caught up to the advancements in 3D printing. Creators can’t control how their designs are used, leading to unauthorized reproductions or IP infringements.
Different jurisdictions: 3D design files can be easily shared across borders, making it unclear which set of IP laws apply.

How to Protect IP in 3D Printing

If you use 3D printing for personal or business use and feel concerned about intellectual property infringement (you should), you can take steps to secure your files.

Data transfer protocols: Enhance the security of your software and machines by implementing secure protocols, such as Transport Layer Security (TLS). It allows you to encrypt the data as it moves between networks.
Blockchain technology: Store cryptographic hashes (“fingerprints”) of 3D design files on a blockchain to ensure the authenticity of the file. You’ll be able to see if anything has been tampered with. You can also record ownership and licensing info on the blockchain, creating a transparent record of your IP.
Digital watermarking: Digital watermarking works similarly to blockchain storage, but it has some limitations—for example, companies could digitally watermark a physical product, then continue to track its use even after it’s been sold.

Although IP laws aren’t rock-solid, you should still explore copyrights and patents or your 3D printing designs as well. That way, if you do detect infringement or unauthorized use, you have a legal framework to potentially fall back on.

How to Avoid Violating IP with Your Own 3D Printing Project

It’s important for everyone using 3D printing to take IP seriously. If you’re using one for your business or for personal projects, you should try to avoid stealing someone else’s intellectual property.

When starting a new 3D printing project, ask yourself these questions:

Are you starting the project with a scan of a pre-existing object? And is this object copyrighted?
Are you using a design file created by someone else? Is the file copyrighted, even if the object is not?
Are you planning to sell or license your 3D projects? Is it considered a “useful” object?

Be careful when using 3D print designs that you didn’t create yourself, and always confirm where they came from.

Protecting the Future of 3D Printing Starts with IP Security

3D printing continues to revolutionize manufacturing, design, and innovation. It also requires a smarter, stronger approach to protecting intellectual property. The technology’s digital foundation makes it inherently vulnerable, but that doesn’t mean creators and companies are powerless. By combining legal protections with proactive cybersecurity tools like encryption, blockchain, and digital watermarking, it’s possible to reduce risk and defend what matters most: your ideas.
