Tools and Preparation
- Laser cutter fibre or diode, depending on your material
- Computer with design software (like LaserPecker Design Space, Illustrator, CorelDRAW, or LightBurn)
- Acrylic sheets, wood panels, leather pieces, metal sheets, or cardboard
- Safety glasses, gloves, and a ventilation system
Your Letters Design (vector files, fonts, layouts)
1. Create your design as a vector file (SVG, DXF, or AI).
2. Choose fonts that are thick since thin lines can break.
3. Arrange your designs to minimize material waste.
Laser Cutting Process
Setting up the machine
Place the material flat on the laser bed. Secure it using clamps or magnets to prevent any movement during operation.
Adjusting power, speed, and focus
Start by setting the correct focus using the machine's focus tool. Then adjust power and speed settings based on the material.
Always test on scrap material first to fine-tune parameters and avoid mistakes on your final piece.
Cutting and engraving steps
- With the settings dialled, start the cut.
- The laser will follow your design to cut each letter.
- If you're engraving details inside the letters, do that before cutting the outline.
Finishing touches (polishing acrylic edges, painting wood, etc.)
- Acrylic: Clean the shiny edges and use a flame to polish them more, if desired.
- Wood: Lightly sand off any burn marks, then paint or varnish.
- Metal: Brush or polish the edges.
- Cardboard: Usually, no finish is needed, but you can paint it to make it more durable.
To care for leather after engraving, wipe away any leftover material. Then, use a leather conditioner or wax to keep the leather soft and prevent it from drying out.
