LONGER How to：How to use laser to engrave ceramics

Laser engraving ceramics, especially white porcelain, can be challenging because the smooth and reflective surface does not easily absorb laser energy. Without proper preparation, the laser may not create clear marks on the ceramic surface.

This guide uses the Longer Ray5 10W laser engraving machine as an example to explain how to engrave white porcelain. It covers material preparation, LightBurn parameter settings, engraving steps, and post-processing methods to help users achieve clearer and more detailed engraving results.

Why Laser Engraving White Porcelain Requires Preparation

White porcelain is widely used in tableware, decorations, and creative DIY projects. However, its smooth surface reflects a large amount of laser energy, making direct engraving difficult.

To improve engraving results, a masking method can be used before engraving. Applying color paper to the porcelain surface helps the laser interact with the material more effectively, improving engraving consistency and pattern clarity.

Before You Start

Requirements

• Ray5 10W laser engraving machine
• White porcelain object
• Color paper (for masking)
• Clean water container
• Soft scraping tool
• LightBurn software

Precautions

• Always work in a ventilated environment
• Do not touch laser components during operation
• Ensure the porcelain is stable during engraving
• Handle sharp tools carefully during cleaning
• Follow official machine specifications or instructions when unsure

Step-by-Step Tutorial

Below is the full workflow for engraving white porcelain using the Ray5 10W laser engraving machine.

Step 1: Material preparation

White porcelain cannot retain energy on the surface for engraving due to reflection, so it is necessary to paste color paper on the white porcelain before engraving:

1. Cut the color paper according to the size of the required engraving pattern
   
2. Soak the cut color paper in water
   
3. Paste the soaked color paper on the white porcelain and let it dry

Tips: Make sure there are no air bubbles or wrinkles between the paper and the porcelain. An uneven surface may affect engraving results.

Expected result: The porcelain surface is fully covered with a dry masking layer and ready for laser engraving.

Step 2: Set Engraving Parameters in LightBurn

After preparing the material, configure the engraving settings in LightBurn. Recommended settings:

• Speed: 1000 mm/min
• Power: 100%
• Constant Power Mode: Enabled

These parameters help provide stable laser output during the engraving process.

Before starting the full engraving job, it is recommended to test the settings on a small area to confirm the result.

Step 3: Start the Engraving Process

After completing the LightBurn setup:

1. Import your design file into LightBurn.
2. Position the design correctly.
3. Start engraving with the Ray5 10W laser engraving machine.

During engraving, the laser will process the color paper layer on the porcelain surface and create the desired pattern.

Important Notes: Keep the porcelain stable during engraving. Any movement may affect the alignment and final result.

Step 4: Remove the Masking Layer and Check the Result

After engraving:

1. Place the porcelain into water.
2. Allow the color paper to soften.
3. Carefully remove the remaining paper with a scraping tool.

After cleaning, the engraved pattern will become visible on the porcelain surface.

Tips: Remove the paper gently to avoid damaging the engraved area and to keep the pattern details clear.

Common Problems and Solutions

Tips for Better Results

• Ensure the color paper is fully soaked before application for better adhesion
• Allow sufficient drying time before engraving begins
• Use smooth and even pressure when applying the masking layer
• Keep the engraving surface completely stable during operation
• Test on a small sample before full production
• Adjust color paper thickness depending on pattern complexity for improved precision

These small adjustments can significantly improve results when performing laser engraving white porcelain or other ceramic materials.

FAQ

1. Why is color paper needed for porcelain engraving?

White porcelain reflects laser energy, making direct engraving ineffective. The masking layer helps improve energy absorption.

2. Can I engrave porcelain without pre-treatment?

It is not recommended, as results will likely be inconsistent or unclear.

3. What software is used for engraving setup?

LightBurn is used for configuring engraving parameters.

4. Why is soaking required after engraving?

Soaking softens the color paper so it can be removed easily without damaging the engraved pattern.

5. What is the best laser engraver for this process?

This guide uses the Ray5 10W laser engraving machine as an example.

6. Can this method be used on other ceramics?

Yes, similar ceramic surfaces may use this method, but adjustments may be required depending on material properties.

Conclusion

Laser engraving white porcelain requires proper surface preparation because ceramic materials have highly reflective surfaces. By using a color paper masking method, suitable LightBurn settings, and careful post-processing, users can achieve clearer engraving results.

The Longer Ray5 10W laser engraving machine provides a practical solution for ceramic engraving projects. With the right preparation and parameter adjustments, creators can produce detailed patterns on porcelain and explore more possibilities for laser engraving applications.
