When selecting a design for laser cutting, it’s crucial to consider the concept of laser kerf, which refers to the width of the material that’s removed during the cutting process. Here are several considerations to keep in mind:

• Kerf Width: The kerf width varies depending on the type of material, laser power, and settings. Be sure to know the kerf width for your specific laser and material to account for it in your design.
• Dimension Tolerance: If precise fitting is required, incorporate adjustments in the design to compensate for the kerf. For example, if two pieces need to fit together, ensure their dimensions are slightly larger than the kerf.
• Joint Designs: Design joints and interlocking features thoughtfully. If joints are too tight, they may not fit due to kerf material removal.
• Material Choice: Different materials have different kerf widths. Thinner materials typically yield less kerf, while thicker materials might require more significant adjustments.
• Experimentation: Before finalizing your design, conduct test cuts to observe the actual kerf and adjust your design accordingly.

By considering these factors, you’ll create designs that fit well and function as intended after laser cutting.
