With the development of AI technology, laser engraving has become easier and more efficient. LONGER LaserBurn integrates multiple AI-powered tools to help users simplify the design and engraving workflow.
This guide introduces the four main AI features in LaserBurn:
- Text-to-Image
- Image-to-Image
- Auto Focus
- Batch Fill
You will learn how each feature works, how to use them step by step, and how they can improve your engraving workflow.
1. Overview of LaserBurn AI Features
Before using the AI tools, it is important to understand the basic functions of each feature.
1.1 Text-to-Image
Feature Overview: Text-to-Image is the core AI image generation feature in LaserBurn.
Users can enter a description prompt, and the AI system will create a new image based on the provided text. It is useful for quickly generating creative ideas, product designs, and engraving patterns without starting from scratch.
1.2 Image-to-Image
Feature Overview: Image-to-Image allows users to modify an existing image with AI.
By adding new prompts, users can change the image style, atmosphere, details, or overall composition while keeping the original structure. This feature helps improve designs and create different visual effects more efficiently.
1.3 Auto Focus
Feature Overview: Auto Focus automatically adjusts the laser focus position without manual calibration.
LaserBurn detects the correct focus point by identifying when the two focus points meet. This helps achieve accurate focusing, reduce adjustment errors, and improve engraving consistency. The automatic adjustment process makes focusing faster and more convenient.
1.4 Batch Fill
Feature Overview: Batch Fill helps users engrave multiple similar objects at the same time.
With the built-in camera, LaserBurn can recognize and align multiple materials automatically, then apply the same engraving pattern to each object. This feature improves production efficiency and keeps engraving results consistent.
2. Step-by-Step LaserBurn AI Workflow
The following example shows how to combine all four AI features to create a Cyberpunk-style phone case engraving project.
Step 1: Text-to-Image — Create the Initial Concept
Goal: Generate the main product visual for a cyberpunk-themed phone case.
Process:
- Open the Text-to-Image module in the AI creation tool.
- Enter the prompt — this is the key step; the more detailed, the better.
Prompt (positive):
Cyberpunk phone case, glowing neon blue liquid, intricate circuit pattern on surface, metal texture, dark background, cinematic lighting, futuristic, 8k, highly detailed
Prompt (negative):
blurry, ugly, deformed, watermark, text
The negative prompt helps remove unwanted elements.
- Select the generation settings:
- Style: Choose a colorful and futuristic style.
- Aspect ratio: Select 9:16 or adjust according to your design needs.
- Click Generate to create the image.

Step 2: Improve the Design with Image-to-Image
Goal: Keep the phone case design but make the background more dynamic and futuristic.
Process:
- Import the generated image from Step 1 into the Image-to-Image module.
- Enter the new prompt:
A busy neon-lit city street at night with cars flying by in the background and lights reflecting off the rain-soaked ground - Select the output image that best integrates the product and background.

Step 3: Use Auto Focus Before Engraving
Goal: Ensure precise laser focus to avoid uneven engraving caused by incorrect focal distance.
Process:
- Place the phone case under the laser head.
- In the focus settings, click Auto Focus.
- The machine will automatically adjust until the two focus points converge — then you can proceed to engraving.

Step 4: Batch Fill
Goal: Automate multi-object engraving to ensure high consistency and productivity.
Process:
- On the left toolbar, select the Camera function and click Capture.
- Place the materials to be engraved within the working area, then position one reference item on the material surface.
- Enable the AI Enhancement Mode and click Batch Fill.
- Wait until all engraving objects are properly recognized and duplicated across materials.

3. LaserBurn AI Application Scenarios
The four AI features support different stages of the creative and engraving process.
3.1 Text-to-Image Applications
Suitable for:
- Concept design
- Game characters and environments
- Creative artwork generation
- Social media visual creation
3.2 Image-to-Image Applications
Suitable for:
- Image style transformation

- Old photo restoration and enhancement
3.3 Auto Focus Applications
Suitable for:
- Uneven material surfaces
- Automatic focus adjustment
- More accurate positioning before engraving
The system uses automatic adjustment to help maintain a stable focus position.
3.4 Batch Fill Applications
Suitable for:
- Serial number engraving
- Logo engraving
- QR code engraving
- Name engraving
Example:
- Entering:
No: 1,can generate a sequence:No: 2, No: 3, No: 4...
This makes repeated engraving tasks more efficient.
Conclusion
The AI features in LONGER LaserBurn provide a more efficient workflow from design creation to final engraving.
By combining Text-to-Image, Image-to-Image, Auto Focus, and Batch Fill, users can create designs faster, improve engraving accuracy, and handle repeated production tasks more easily.
