1. Page Overview
①Enter QR Code
Content
In the input box, you can enter any of the following types of content:
· Wi-Fi credentials: SSID (network
name) and password
· Website URLs: Direct users to a
specific page (note: some phones may not auto-open browsers)
· App download links: App Store or
Google Play app pages
· Contact information (vCard): Name,
phone number, email, company, job title
· Social media profiles: Links to
Facebook, Instagram, Twitter, etc.
Note:
If the input content is
too long, the dots (modules) in the QR code will become very small. This may
affect print quality and make the code difficult to scan. It is recommended to
keep the content under 160 characters for optimal results.

After entering the
content, click “Next” to generate the corresponding QR code.
② Add a Title
Below the QR Code
You can add a text title below the QR code to describe its content — for example, “Wi-Fi Password,” “Download Link,” or “My
Business Card.”
The title will be
displayed under the generated QR code, making it easier to identify or
categorize.

③ Font
Selection
Two font options are
available:
Noto Sans Mono (default): clean and clear, ideal for 3D printing.
Noto Serif: thinner strokes, which may affect the printing outcome.

2. Operation Steps
1. Enter the desired QR
code content in the input box;
2. Add a title below
the QR code to describe its purpose;
3. Click “Next” to preview the QR code. After
confirming it, click “Submit”
to automatically generate a printable model.

3. Printing Guidelines
① Parameter
Settings:
Click on the “Customize” option
to view and adjust the default print settings.
By default, a brim is
added to the model to prevent warping caused by temperature or filament issues.
It’s recommended to remove the brim promptly after printing, as it may
become harder to remove after the model cools down.
If you prefer not to
use a brim, you can choose “No Brim” in the customization settings.
② Printing
Settings:
The QR code sign is
designed as a dual-color print model. When the printer reaches a
specific height, it will automatically prompt a “Change
Filament” operation. Please follow the on-screen
instructions to complete the filament swap.
Please use black and
white filament whenever possible when printing QR codes. Using other color
combinations with low contrast may result in the QR code being unreadable or
unscannable.
⚠ Caution:
After loading the new filament, the nozzle will purge a short strand of excess
material. Use a tool to remove it promptly.
Do not place your hands inside the machine during the process
to avoid injury.
4. How to
Use
After printing the QR code plate and the base, insert the
plate into the slot on the base.
