10. Once you Sign Up, click on the download icon. A pop-up will appear, prompting you to specify the size and format of the QR Code image (choose SVG for 3D printing purposes).
Once you enter the details, click Export
That’s it. Your website URL has now been converted to a QR Code. Simply test it once before you go ahead with 3D printing it.
C. Step two: How to 3D print a QR Code
The next step is to turn your QR Code into a 3D model before using a 3D printer to make it a reality. This allows you to print a tangible copy of your scannable QR Code with an original, interactive layout.
We recommend using Blender, a robust, open-source, and 3D program, to accomplish this.
Blender is a flexible tool for producing 3D-printed models, animations, visual effects, and even virtual reality experiences. It’s an excellent option for creating a 3D object from a 2D QR Code. Here’s how to do that:
1. Open Blender or any other 3D software
Import your QR Code as an SVG (Scalable Vector Graphic) file into Blender (or a comparable application). Your QR Code’s vector-based components are preserved in an SVG, facilitating manipulation and 3D conversion.
2. Import the SVG file
Choose the option to import the SVG file in Blender. You may start working with your 2D QR Code design once loaded into the 3D workspace.
3. Join the curves
There will be a variety of curves and lines in the QR Code design. These curves must be chosen and joined to form a cohesive design. Before converting the code to 3D, this is an essential step to ensure that every component is aligned appropriately.
4. Extrude the design
Once you have the unified QR Code, the next step is to give it depth. Use Blender’s extrude tool to pull the 2D design into the third dimension, creating a raised effect for each square of the QR Code.
5. Add a cube for the frame
Add a cube under the “Mesh” option to give the QR Code a polished appearance. This cube will surround your QR Code like a frame. To make the cube more aesthetically pleasing and manageable throughout the printing process, use Blender’s bevel modifier to soften its sharp edges.
6. Export the model
Once you have made the necessary changes to the shape and design, export the model in the stereolithography (STL) format. STL files are ideal for your next step because they are widely compatible with 3D printers.
7. Open in Cura
Open Cura, the slicing program used to get 3D models ready for printing and import your exported STL file. You may change the parameters in Cura, including the print speed, layer height, and other crucial elements.
8. Slice the model
To get the 3D model ready for printing, click the “Slice” option in Cura. The G-code, a language that instructs the 3D printer on constructing the object layer by layer, is created in this step.
9. Pause for layers
Identify the base layer of your 3D QR Code model. Decide at which layer you want the 3D printer to pause (this can be helpful if you want to add additional elements or features during the print). Add a “Pause at Height” script, specifying the layer number to pause the print process.
10. Prepare for printing
Save the G-code to an SD card after you’ve made the necessary adjustments, and it’s ready. Your 3D QR Code is prepared for printing as you insert the card into your 3D printer.
You may create a fully functional 3D-printed QR Code that mobile devices can scan by following these steps.
This procedure gives your project a creative touch while enabling you to produce a distinctive, physical version of your QR Code.
