3D Print QR Codes: What You Need to Know
With their ability to provide instantaneous access to information by scanning, QR codes have grown popular in this era of rapid technological innovation. Developed initially for the automotive industry in 1994, QR codes have now expanded their use to a wide range of industries. The creation of 3D printed QR codes can be an interesting and useful project, whether the goal is to demonstrate the possibilities of 3D printing or to improve functioning.
Step 1: Generating the QR Code
Designing the code is the initial stage in the process of 3D printing a QR code. There are a number of straightforward web applications, such as Qrcode2stl, Polo's QR code generator, and free qr code generator, that make this process a breeze. You can modify the dimensions, width, depth, and border of your 3D model after entering the necessary data, which can be a URL, an image, or even just plain text.
You can personalize the QR codes with your own text or attach it to a keychain. Select "Generate 3D Model" when you're through with the options. A preview of your QR code appears on the right.
To save the plan as a file, click "Save as STL" after you're satisfied with it.
Step 2: Setting Up for Printing
After generating the STL file, you can import it to a 3D printing software like SelfCAD. We recommend SelfCAD as it is easy to use and you can use it to modify the file based on your requirements and you can also slice all under one program without the need for an additional software. After importing, you can properly orient it to the workspace to make it easier to print without supports. To access the slicer, click on 3D Print
Once you click it, you will be redirected to a new tab where you can select your 3D printer and then start applying the necessary settings. After that, click slice and then you can preview to see how it will be 3D printed. If everything is set, save the G-code then send it to your 3D printer. To learn how the slicer of SelfCAD works, you can check the video below.
Step 3: 3D Printing & Post-processing
To make scanning the QR code easier, use contrasting colours for the code and background. For best results, use a dark code on a light background. Two primary techniques exist for accomplishing this contrast: painting and multicolor 3D printing.
Either employ a dual-extrusion technique or pause the printer at the correct layer to swap filaments for multicolor 3D printing. Although painting is a less complicated option, accuracy is essential. For uniform coverage, use a flat implement, such as a sponge, to paint just the top surface of the QR code.
