To ensure that your laser cut joints fit tightly and securely, consider the following tips:

• Precision Settings: Use the appropriate settings for your laser cutter, including speed, power, and frequency. Fine-tune these settings based on the material thickness for optimal accuracy.
• Kerf Width: Account for the kerf (the width of the cut made by the laser) in your designs. Adjust the dimensions of your joints accordingly to compensate for any material removed during the cutting process.
• Test Cuts: Perform test cuts on scrap material to ensure the joints fit as expected. This allows you to make adjustments before cutting your final pieces.
• Material Selection: Choose the right material that responds well to laser cutting. Some materials may warp or shrink, impacting the fit of your joints.
• Joinery Design: Opt for proven joinery techniques such as finger joints, dovetails, or lap joints, which can enhance strength and fit.
• Assembly Techniques: Utilize clamps or jigs during assembly to hold the pieces in place until the adhesive sets, ensuring a secure fit.
