When families invest in a monument, they expect it to last for generations. Deep engraving is a cornerstone of creating durable, meaningful tributes that withstand the test of time. Laser technology has revolutionized this aspect of the monument industry, enabling precision and depth that surpass traditional methods.
But just how deep can lasers go? And how does laser type—fiber vs. CO₂—affect the results? Let’s explore the details.
How Deep Can Lasers Engrave?
The depth achievable by a laser depends on the material, the laser type, and the power settings. Here’s a breakdown:
- Granite and Marble
- Typical Depth: Most industrial lasers can achieve engraving depths of 1–3 mm in granite or marble, depending on the laser's power.
- Extended Depths: With multiple passes, some high-powered lasers can engrave up to 5 mm or more, allowing for bold, long-lasting designs.
- Durability: Deeper engravings resist weathering and erosion, making them ideal for outdoor monuments.
- Other Materials
- Metal: Fiber lasers excel in metals, achieving depths of 0.5–1 mm in a single pass, with extended depths possible with multiple passes.
- Glass: Lasers typically create surface-level frosted engravings on glass, as deeper cuts may compromise the material’s integrity.
Fiber Lasers vs. CO₂ Lasers: Which Goes Deeper?
Both fiber and CO₂ lasers are effective for engraving, but they differ in their capabilities, especially for depth and material compatibility.
1. Fiber Lasers
- Depth Capability: Fiber lasers are excellent for deep engraving on hard materials like metal and granite. They can achieve depths of 1–3 mm in a single pass on metals and stones.
- Precision: Fiber lasers operate at a shorter wavelength (1.064 microns), enabling finer control and deeper penetration in dense materials.
- Material Compatibility: Ideal for metals, granite, and other dense substrates. However, they may not perform as well on softer materials like wood.
2. CO₂ Lasers
- Depth Capability: CO₂ lasers are versatile and effective for materials like wood, glass, marble, and softer stones. On hard surfaces like granite, their depth is typically limited to 1–2 mm per pass.
- Power Requirements: Achieving comparable depths to fiber lasers often requires higher power and more passes, which can extend engraving times.
- Material Compatibility: Better suited for organic materials like wood, acrylic, and leather, but still effective for surface-level or shallow engravings on stone.
Choosing the Right Laser for Deep Engraving
The choice between fiber and CO₂ lasers depends on your materials and engraving goals:
| Feature | Fiber Laser | CO₂ Laser |
|---|---|---|
| Ideal Materials | Granite, marble, metal | Marble, softer stone, wood, glass, acrylic |
| Engraving Depth | 1–3 mm (single pass); up to 5 mm (multiple) | 1–2 mm (single pass); 3–4 mm (multiple) |
| Precision | High, even on dense materials | Moderate; excels in organic materials |
| Engraving Time | Faster for hard materials | Longer for similar depths |
Why Deep Engraving Matters
Deep engraving isn’t just about aesthetics; it’s about ensuring durability and readability over decades, even in harsh conditions. Here’s why depth is critical:
- Weather Resistance: Deep engravings maintain their clarity despite exposure to rain, wind, and sunlight.
- Legibility: Text and designs remain visible over time, even on worn surfaces.
- Quality Assurance: Clients associate deeper engravings with premium craftsmanship, giving your business a competitive edge.
