  • How to Laser Engrave a White Ceramic Disc (5-Step Complete Guide Using AlgoLaser Alpha MK2)

Laser engraving ceramic has become one of the most dependable ways to create long-lasting, high-contrast artwork on smooth, durable materials. Whether you're producing custom ornaments, personalized coasters, branded merchandise, or decorative tags, engraving a white ceramic disc with a diode laser engraver delivers clean detail and permanent results. In this guide, I’ll walk you through exactly how to laser engrave a white ceramic disc using the AlgoLaser Alpha MK2 20W laser engraver, complete with real parameter settings, a detailed workflow, and step-by-step instructions for professional results.

 

You’ll learn how to prepare the ceramic surface, how to work with laser engraving marking paper, how to calibrate focus, and how to generate your text engraving using AlgoType before starting the engraving process.

Why White Ceramic Discs Are Ideal for Laser Engraving

White ceramic discs—often sold as ornaments, blank coasters, or decorative porcelain blanks—are perfect for laser engraving because they’re:

·  Durable and resistant to wear

·  High-contrast when engraved using ceramic marking paper

·  Glazed, allowing the pigment layer to bond cleanly

·  Great for custom crafts and personalized gifts

With the AlgoLaser Alpha MK2 20W, which features spot compression technology and steady motion control, you can achieve extremely fine engraving detail on ceramic surfaces. When paired with ceramic laser engraving marking paper, the pigment reacts with the heat of the laser, producing sharp, dark engraving results that look permanent and professional.

What You Need Before You Begin

·  AlgoLaser Alpha MK2 20W Laser Engraver

·  White ceramic disc (glazed surface)

·  Laser engraving marking paper (ceramic coating paper)

·  Bowl of water (room temperature)

·  Tweezers or plastic scraper

·  Microfiber cloth

·  AlgoType or LightBurn

These items will help ensure your ceramic engraving process goes smoothly and consistently.

Step 1: Place the White Porcelain Plate in the Engraving Area

Begin by placing your white ceramic disc in the center of the engraving area. Accurate placement helps ensure the laser path aligns perfectly with your design once you load the G-code.

 

Tips for stable positioning:

·  Use honeycomb pins or silicone holders to keep the ceramic disc from sliding.

·  Confirm the glazed surface faces upward—this is the surface the laser will mark.

·  Ensure your engraver is on a flat, stable surface to minimize vibration.

This step sets the foundation for a high-precision ceramic engraving workflow.

Step 2: Use the Focal Length Meter to Adjust the Laser Module

Proper laser focus plays a critical role in ceramic engraving. Because ceramic is dense and reflective, a diode laser engraver must be aligned at the correct focal length to penetrate the pigment layer effectively.

 

How to focus the Alpha MK2:

1. Move the laser module directly over the ceramic disc.

2. Insert the focal length meter between the disc and the laser head.

3. Lower the laser module until it gently touches the gauge.

4. Tighten the locking screw to fix the focal position.

5. Slide the gauge out smoothly.

A correctly calibrated focus increases engraving clarity, boosts the reaction of the ceramic marking layer, and ensures consistent engraving depth.

Step 3: Cut the Laser Engraving Marking Paper and Soak It in Water

Ceramic marking paper is essential for diode laser ceramic engraving. This paper carries a thin pigmented film that reacts under laser heat, creating a durable, darkened engraving on glazed surfaces.

 

Follow this preparation process:

·  Cut a piece of laser engraving marking paper slightly larger than your engraving area.

·  Submerge the paper in water for several seconds.

·  Wait until the top colored layer softens and is ready to separate.

The soaking allows the reactive pigment film to detach from the backing, making it easy to apply onto the ceramic disc.

Step 4: Remove the Colored Layer and Apply It to the Ceramic Disc

Once the marking paper has softened, carefully peel off the colored pigment layer. This delicate layer will become the engraving surface.

 

Application tips:

·  Lay the colored coating flat onto the ceramic disc.

·  Smooth out bubbles and wrinkles using a scraper, card, or fingertip.

·  Make sure every part of your engraving area is fully covered.

·  Allow it to rest for a moment to fully adhere.

This step ensures the ceramic disc has a consistent heat-reactive layer that the diode laser can bond with during engraving.

Step 5: Click AlgoType, Enter Text, Load the G-Code, and Begin Engraving

Now it’s time to personalize and engrave your ceramic disc.

 

1. Open AlgoType

AlgoType allows you to create engraved text quickly. 
Input your message, name, monogram, date, logo, or custom wording.

 

2. Generate or Import Your G-code File

·  If using AlgoType: Generate the engraving G-code directly.

·  If using LightBurn: Import the design, adjust the workspace, and export the G-code.

 

3. Start the Engraving

·  Load the G-code into the Alpha MK2.

·  Preview the engraving area.

·  Start the job when ready.

Once the engraving completes, remove the residual pigment layer from the ceramic disc using water and a microfiber cloth.

Final Cleanup: Remove Remaining Colored Layers

After engraving, gently wash the ceramic disc to remove leftover film. The engraved areas will reveal a clean, darkened, permanent design.

 

You can clean with:

·  Microfiber cloth

·  Mild water rinse

·  Soft circular motion

6 Frequently Asked Questions

1. Why is ceramic marking paper necessary for diode laser engraving?

Ceramic surfaces don’t naturally react to diode lasers. Marking paper provides the heat-reactive pigment layer needed for permanent engraving.

 

2. What happens if bubbles stay under the film?

Air pockets interfere with the burn pattern and cause patchy engraving results. Smooth the film before engraving.

 

3. Why does the engraving look light?

Increase power or reduce line interval (to 0.08–0.10 mm). Ceramic requires precise laser density for deeper burn contrast.

 

4. Does ceramic engraving wash off?

No. Once engraved, the ceramic marking becomes permanent and dishwasher-safe.

 

5. Can I engrave without soaking the marking paper?

Soaking is essential. It softens the pigment layer, allowing it to transfer effectively onto ceramic.

 

6. Do I need multiple engraving passes?

One pass is usually enough with ceramic marking paper. Additional passes can overburn or distort the coating layer.
