Стеклянная гравюра традиционно была доменом роторных инструментов и песочной обработки, but with a fiber laser and a little prep work, you can achieve crisp, detailed etchings on glass surfaces—no special attachments required. Ниже, we’ll walk you through a proven three-step process, originally shared by one of our customers, and show you how to adapt it to your ComMarker волоконный лазерный гравер for consistent, high-contrast results.
Why Fiber Laser for Glass?
Most fiber lasers operate around 1064 нм, a wavelength that glass does not absorb efficiently. Однако, by using a temporary marking layer, you can harness the pinpoint focus and high speeds of a fiber laser—like a ComMarker B6 JPT MOPA или КомМаркер Титан 1—to leave a permanent, frosted design on your glass. The benefits:
- Точность: Micron-level focus yields sharp edges and fine details.
- Скорость: Engrave in seconds—with speeds up to 15,000 mm/s on ComMarker machines.
- Универсальность: No need for rotary fixtures; flat glass, бутылки, and vases all work.
- Долговечность: The final etch is permanent, weather-resistant, and dishwasher-safe.
What You’ll Need
- Glass item—anything from flat panels to wine bottles.
- Rust-Oleum 2X paint (Ivory Silk or flat white)—temporary marking layer.
- Paint sprayer or aerosol—for even coverage.
- Paint thinner—for post-engraving cleanup.
- Волоконный лазерный гравер ComMarker—we recommend a 20 W+ unit with MOPA capability for optional color marking.
Шаг 1: Prep & Paint Your Glass
- Clean thoroughly—remove oils, отпечатки пальцев, and dust with isopropyl alcohol.
- Spray a thin, even coat of Rust-Oleum 2X Ivory Silk (or flat white) over your engraving surface.
- Hold can 8–12 inches away for a fine mist.
- Rotate bottles or move panels to avoid drips.
- Let it dry completely—at least 15–20 minutes in a dust-free area.
- Optional second coat if coverage is uneven.
Why Rust-Oleum? Its flat finish absorbs laser energy consistently, so you’ll get uniform etches without glaze or hotspots.
Шаг 2: Настройки лазера & Фокусировка
With your glass painted and dry, it’s time to dial in your ComMarker settings:
| Параметр | Recommended Value |
|---|---|
| Мощность лазера | 20–30 % (start low, then adjust) |
| Скорость | 10 мм/с (for deep etch) |
| Частота | 80 кГц |
| Line Spacing | 0.1 мм (100 мкм) |
| Режим штриховки | 45° or “Crosshatch” for uniform fill |
| Проходы | 1 (usually sufficient) |
- Автофокус your ComMarker head on the painted surface.
- Run a quick test on scrap glass or painted tile with a small circle to verify contrast.
- Отрегулируйте питание в 5 % increments if your etch is too shallow or too dark (risks chipping the paint).
Шаг 3: Гравировать & Clean Up
- Гравировать your design—vector cut or bitmap hatch. The laser vaporizes the paint layer, exposing the frosted glass below.
- Wipe away the remaining paint with a lint-free cloth dampened in paint thinner or acetone.
- Rinse and dry the glass to remove any residue.
Результат? A crisp white frosted design that’s fully bonded into the glass surface.
Pro Tips for Spectacular Results
- Keep it thin: Thick paint layers can lead to uneven etching or flaking.
- Mind the edges: Avoid painting over curved or lip areas—focus on the flat center for best focus.
- Test small: Always run a 10 × 10 mm test square to fine-tune settings before your final piece.
- Use MOPA: Если у тебя есть КомМаркер Титан 1, try longer pulse widths for subtle color shifts (grey, bronze) on clear glass.
- Safety first: Wear laser-safe goggles and ensure proper ventilation when using solvents.
