QR Code Operation Guide

1. Page Overview

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.

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.

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.

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.
