When using a laser cutter for 3D illusion art, several settings are crucial to consider to achieve optimal results. First, material type plays a significant role. Different materials, such as acrylic, wood, or cardboard, require varying power and speed settings. Use a material guide provided by your laser cutter manufacturer to adjust settings accordingly.

Next, power settings should be calibrated based on the material thickness. Higher power settings may be necessary for thicker materials to ensure full engraving or cutting through. Conversely, lower power is ideal for thinner materials to avoid burning.

Speed settings also impact the quality of the cut or engraving. Slower speeds allow for deeper engravings, which can enhance the 3D effect but may require more time. In contrast, faster speeds are suitable for lighter engravings.

Additionally, consider focus settings. Ensuring the laser is correctly focused on the material surface is essential for precision. Regularly check and adjust the focal lens as needed.

Lastly, air assist settings can help reduce smoke and material debris during cutting, leading to cleaner edges.
