*RFID tags are becoming increasingly common in 3D printing to simplify filament spool management. When you install a new spool, the printer automatically detects the material type and color without any manual input on the screen. Anycubic equips its spools with preconfigured RFID tags, but we all use filaments from different brands that don't always have this technology or whose tags aren't compatible with Anycubic printers.*

**This tutorial explains how to add compatible RFID tags to any filament spool.**



**Required Materials**

* **RFID sticker tags** (recommended: NTAG 213 or 215)
* **Android or iOS smartphone** with NFC function
* **ACE RFID app** (free download)



**Step 1: Preparing the RFID Tags**

1. **Tag placement**: Stick one RFID sticker tag on **each side of your spool**, at the location closest to your printer's RFID reader.
2. **Why two tags?** This ensures optimal reading regardless of the spool's orientation.



**Step 2: Installing and Configuring the App**

1. **Download the ACE RFID app** from the Play Store (Android) or App Store (iOS).
2. **Enable NFC**: On first launch, the app will ask you to enable your phone's NFC function if it's not already active.
3. **Intuitive interface**: The app offers a clean, user-friendly interface that's easy to navigate.



**Step 3: Creating the Filament Profile**

In the app, configure your filament settings:

**Material Type**: Select from a wide range of filaments (PLA, PETG, ABS, TPU, etc.). If your material isn't listed, you can create a custom profile.

**Spool Weight**: Choose from: 1kg, 750g, 600g, 500g, or 250g.

**Filament Color:**

Several methods are available:

* **Presets**: Predefined colors
* **ARGB Slider**: Sliders to adjust RGB values
* **Color Picker**: Visual color selector
* **Hexadecimal format**: Direct color code entry
* **Photo Color**: The app analyzes a photo of your filament to automatically detect the color



**Step 4: Writing the Profile to the Tag**

1. **Bring the tag close to your phone**: The phone will vibrate slightly when the tag is detected. The tag's identification information will appear on screen.
2. **Click "Write"** to transfer the profile to the RFID tag.
3. **Repeat the operation** for the second tag on the other side of the spool.



**And that's it!** Your spool is now equipped with RFID tags compatible with your Anycubic printer.



**Additional Features**

**Reading an Existing Tag**

Use the **"Read"** button to view information stored on an RFID tag.

**Formatting an Incompatible Tag**

If your spool already has an incompatible RFID tag:

1. Open the **side menu** (icon at the top left of the app)
2. Select **"Format Tag"**
3. Bring the tag to erase close to your phone
4. Confirm data deletion
5. Then follow the normal procedure to write your new compatible profile





**Important Information**

**Profile distinction:**

* The term "profile" in the ACE RFID app refers only to the **physical characteristics** of the filament (color, weight, material)
* It does **not** refer to print settings in Anycubic Slicer Next

**Using with the printer:** Once your Ace Pro is synchronized, Anycubic's default print profiles will automatically appear. You'll need to select the appropriate print profile in the slicer based on the material detected by the RFID tag.



*Here's a mod that allows you to* [insert an RFID tag into a removable holder](https://makeronline.com/en/model/Re-Tag:%20A%20removable%20RFID%20TAG/267783.html?trackModuleType=10)*, which you can move and reuse endlessly as needed*



**With this method, all your spools now benefit from automatic recognition and remaining filament (ACE2P) for a simplified printing experience!**
