Step-by-Step Guide for Beginners
Preparing Your Leather for Cutting
Material Selection: Choose leather according to project specifications. In general, for very crisp cuts, vegetable-tanned leather is preferred. Chrome-tanned leather shades are rather used for softer lines.
1Cleaning the Leather
Dust must not interfere with the cutting. The surface of the leather should be wiped off with a damp lint-free cloth. The more water is used upon leather, the more alteration it will cause to the texture, and the least conducive it would be for cutting.
2Flat Surface
Make sure the surface is flat on the bed of the laser cutter; otherwise, part of the leather may get uneven cuts. Put some weight on the curled edges. Masking tape, or magnets, could help in this case for bigger pieces.
3Test Settings
Speed, power, and focus must all be perfectly balanced on the laser cutter for cutting leather.
| Leather Thickness | Power Setting | Speed Setting | Application |
|---|---|---|---|
| 1.5mm | 40-60% | 20 mm/s | Cutting |
| 1.5mm | 15-25% | Variable | Engraving |
4Safety Considerations
Fumes and odors coming from leather cutting can be injurious. Do work in an environment with good ventilation, where your exhaust system and air filter of the laser cutter are working well. Be especially respectful to a vegetable-tanned leather, in that chrome tanned could produce harmful gases.
Setting up the Laser Cutter
Choose the proper ventilation system.
Safety and performance require ventilation. Typical airflow for a Class-1 or small Class-2 machine would be anywhere between 500 and 600 CFM in order for the workstation to be considered safely ventilated.
Align the Laser Beam
A laser beam that is misaligned often leads to uneven cutting or wastes the material. Make sure to align the beam along both the X and Y axes of the cutting bed using the calibration tool.
Choose Settings Appropriate for the Materials
| Material | Power | Speed | Application |
|---|---|---|---|
| Vegetable-tanned leather | 40% | 300 mm/s | Engraving |
| Vegetable-tanned leather | 50% | 200 mm/s | Cutting |
| Acrylic (3mm) | 60% | 400 mm/s | Cutting |
Tips for Achieving Precise and Clean Cuts
Adjusting Speed and Power Settings
Proper calibration of speed and power must be adjusted in order to achieve precision and clean cut with laser cutting. The right combination depends on the material you are working with, its thickness, and desired cut quality.
| Material | Thickness | Power | Speed |
|---|---|---|---|
| Acrylic | 3mm | 50% | 15mm/s |
| Plywood | 4mm | 80% | 10mm/s |
| Cardstock | – | 30% | 20mm/s |
| Stainless Steel | 1mm | 95% | 6mm/s |
