Creative ways to use a 3D print QR code

The ability to print QR codes in 3D opens up numerous practical applications, from unique everyday tools to innovative art and marketing strategies. 

Here are some creative ideas you can try with these tangible QR codes to enhance interactivity and offer a new dimension of engagement to users:

QR code art installation

You can use a URL QR code for your 3D art, leading your audience to your website page that talks about the artwork and your creative process as an artist or reveals hidden content.

This convergence of art and technology opens new avenues for expression and collaboration in the digital age.

QR code keychain

Use a 3D print QR code design to have a unique and functional keychain. 

You can use a vCard QR code to store your personal or business contact information and print it in 3D. 

This is a great accessory to use for your Airbnb or hotel keys, allowing your guests to contact you as soon as possible in case they have requests or concerns about the accommodation. 

With a three-dimensional design, this QR code keychain is more durable compared to its 2D counterpart and doubles as a decorative accessory or promotional item for your business.

It can also help you locate your keys in case you lost them as the finder can just scan the QR code and contact you immediately to return them.

QR code gift stamp

Do you want to gift someone a unique souvenir, like those stamps from Japan that tourists collect? You can also create one by designing a 3D model with a twist: integrating a QR code into the design.

Store a special message on a text QR code and integrate it within the stamp design that reflects the recipient’s unique style and personality before printing it in 3D.

This stamp not only leaves a beautiful imprint but also contains a hidden digital message that the recipient can unlock.

Innovative real-life 3D QR code designs and uses you need to know about

Businesses and individuals are bringing QR codes into the three-dimensional world not just by simply integrating them into flat surfaces but by making the two-dimensional barcode into a 3D itself.

Take a look at how this forward-thinking business uses QR code technology in the three-dimensional format as part of its marketing strategies: 

Korean Emart shadow QR code

QR code marketing is now a common practice for businesses in various industries. However, the Korean retail chain, Korean Emart, takes it further. 

By combining creativity, innovation, and science, the retailer installed shadow-activated QR code sculptures throughout Seoul for their Sunny Sale campaign.

The installation, which is composed of 3D blocks, turns into a QR code once the clock hits noon, which customers can scan to get discounts at the store, increasing foot traffic during this quiet shopping time.

Lego QR code

One of Germany’s largest online toy stores, MyToys.de, uses Lego bricks to create a 3d QR code to promote their LEGO products.

The colorful Lego QR codes were placed all around Germany for passersby to scan, directing them to the shop’s desktop website landing page where they can order the Lego boxes. 

49% of the traffic on Mytoys.de’s website was from the QR code campaign, allowing them to sell the advertised Lego boxes twice as many compared to the ones not on the page.

QR code corn maze

The Kraay Family Farm makes the word massive an understatement by creating a 309,570 square feet QR code maze in the middle of their corn farm.

When you’re in the ground, you can explore the paths around the cornfield, but when you’re above, you can view and scan the QR code, leading you to the family’s website. 

This fully functioning QR code maze was even recognized by the Guinness Book of World Records as the world’s largest.

Best practices for using a 3D print QR code

A 3D-printed QR code can be tricky as you need to print them accurately so they remain readable and scannable.

We have prepared this 3D printing and QR code best practices that can guide you in successfully crafting one for your personal or business needs:

Design a functional QR code

First things first, make sure to create a readable QR code. You can use Free QR Code Generator to create functional yet aesthetically pleasing QR codes. 

Use high-contrast colors and clear, well-defined patterns. Avoid intricate or overly complex designs that may interfere with scanning.

It is advisable to use a dynamic QR code as it has a more efficient data compression technique that reduces the complexity of the QR code pattern, making it easier for QR code scanners to decode the information it contains accurately. 

A dynamic QR code also has a higher level of error correction, improving the overall reliability and readability of the QR code. 

Use trusty 3D modeling software

Modeling can also significantly impact the readability of 3D-printed QR codes. 

Aside from the QR code software, you also need to use a reliable three-dimensional modeling software tool that you can use as a QR code stl generator for 3D printing.

This way, you can ensure that the printer can produce all the parts of the QR code accurately. 

Maintain an appropriate size and scale

Pay attention to the size and scale of your 3D-printed QR codes to ensure that they are neither too small nor too large for scanning.

Codes that are too small may be difficult to scan, especially from a distance or in low-light conditions, while codes that are too large may dominate the design or detract from the overall aesthetic. 

Aim for a QR code size that strikes a balance between visibility and practicality, considering the intended placement and scanning distance.

Choose high-quality materials

Choose materials for your 3D print QR code that are durable and compatible with your intended use case. 

Consider factors such as environmental conditions, handling requirements, and longevity when selecting materials. 

PLA and ABS plastics are commonly used for 3D printing QR codes due to their durability and versatility.

Always test your 3D-printed QR code

Thoroughly test the scannability of your 3D-printed QR code in different scanning distances, angles, and lighting conditions to ensure that it can be reliably scanned in real-world scenarios.

Consider periodically retesting the scannability of the QR code to identify any potential issues.

Frequently asked questions

Will a QR code work if I print it? 

Absolutely. In fact, you can mostly find QR codes printed on physical materials such as posters, product packaging, signage, and more.

Just make sure that you design a readable QR code and print it using high-quality materials to maintain its scannability.

When using dynamic QR codes in print materials, you can redirect existing QR codes to other content without the need to regenerate and reprint the materials.

What is the best format to print a QR code?

A higher resolution helps prevent distortion or blurriness, especially when printing QR codes in smaller sizes.

Use vector graphics formats such as SVG (Scalable Vector Graphics) for printing QR codes, as you can scale it to any size without loss of quality.

You can also consider using the raster image format PNG (Portable Network Graphics). This provides sufficient resolution and clarity for most printing applications, especially when printed at larger sizes.
