Recommended Materials for Plate Engraving
| Material | Tipo Laser | Notas |
|---|---|---|
| Aço inoxidável | Fibra | Deep contrast, especially at 1064nm |
| Alumínio anodizado | Fibra ou UV | Color options with MOPA; good for ID tags |
| Coated Brass/Steel | UV preferred | No charring, retains clean edges |
| Acrílico & Plásticos | ultravioleta | Crisp details without melting |
| Wood Plaques | UV ou co₂ | Optional paint fill after engraving |
Passo a passo: Como fazer placas de gravuras a laser
1. Prep Your Plate
Clean with isopropyl alcohol to remove oils, pó, or protective films. Use masking tape if needed to reduce residue (especialmente em plásticos).
2. Load Your Design in Software
Whether you’re using LightBurn ou EZCAD2, import your vector file (SVG, DXF) or bitmap (JPG, png) and scale it to fit your plate size.
3. Set Your Parameters
Sample Settings for Fiber Laser (B6):
- Material: Aço inoxidável
- Velocidade: 800 mm/s
- Poder: 40%
- Frequência: 30 kHz
- Passes: 1–3
- Hatch: 0.03 mm at 0°/90° crosshatch
Sample Settings for UV Laser (Omni 1):
- Material: Acrylic plate
- Velocidade: 1200 mm/s
- Poder: 30%
- Frequência: 40 kHz
- Intervalo de linha: 0.02 milímetros
💡 Dica: Always do a small test engrave in the corner first.
4. Focus and Frame
Use auto-focus if available. Frame the job area to ensure proper alignment and avoid clipping the design off the edge.
5. Run Your Engrave
Monitor the first pass. If engraving depth or contrast isn’t sufficient, increase the number of passes or adjust the frequency.
6. Limpo e inspecionar
Use a soft brush or microfiber cloth to wipe off debris. For metal plates, a dab of polishing compound can enhance shine.
Common Troubleshooting Tips
| Emitir | Causa | Fix |
|---|---|---|
| Faint engraving | Low power or too-fast speed | Lower speed or increase power |
| Burned edges (plásticos) | Too much heat | Switch to UV laser or lower settings |
| Misalignment | Plate not fixed or beam not centered | Use clamps or run “frame” preview |
| Inconsistent depth | Uneven focus | Check autofocus or use focus gauge |
Best Practices for Long-Term Results
- Batch your jobs: Use a jig or fixture for engraving multiple plates at once.
- Record your settings: Save presets in LightBurn/EZCAD2 for repeat jobs.
- Rotate designs: For multi-directional plates, engrave from different angles for deeper texture.
- Protect your lens: Use air assist or a fan to blow away debris during metal engraving.
