Start by peeling off the protective film from the top surface of the acrylic sheet—the side that faces the laser. This prevents burn marks or smoke stains from forming on the visible surface during cutting.

You can leave the bottom film on to protect the underside while it rests on the workbed. Once ready, place the acrylic flat on the laser cutter’s bed and secure it with pins or magnets.

Open your preferred laser software, such as LaserMaker, and import the piano model design file. Adjust the size and layout as needed, making sure the pieces are evenly spaced to make the most of your acrylic sheet.

For the laser cutting layers, pay extra attention to the minimum power setting. If the min power is too low, the corners may not cut through; if the min power is too high, the corners may not look clean.

Accurate focusing is critical for achieving smooth, clean cuts on acrylic. If your machine has auto focus, use it for quick setup. For manual focusing, lower the laser head with the focus stick until it touches the acrylic surface at the correct angle.

Before starting the job, run the Frame or Border function in your software. The laser head will trace the outline of the design with a visible guide light, helping confirm that the design fits within your acrylic sheet and avoids wasting material.

Once everything is adjusted, start the job and monitor the process as it runs. Watch for excessive smoke, movement of the acrylic sheet, or any warning alarms, and never leave the laser unattended while it’s operating.

When the job is done, wait a few seconds to let any fumes clear before opening the lid. Carefully remove the laser-cut piano pieces from the bed. If the protective film is still on the acrylic, peel it off to reveal the clean surface.

Gently wipe away any residue along the edges with a soft cloth or rinse the acrylic with mild soap and water. Once cleaned and assembled, your miniature acrylic piano is ready to display.
