Operational Process

STEP01

Prepare & Position the Material

Choose a red acrylic board and place it flat on the laser honeycomb bed. You can also change to any color you like for a different style.


Make sure the acrylic stays stable during cutting. Use pins or magnets to prevent shifting and help keep the final 3D heart pieces accurate.

STEP02

Import & Adjust the Design File

Import the 3D heart design into LightBurn and check whether your acrylic size is large enough.


For a design with many elements, make sure there are no misalignments or unnecessary overlaps. Check that the cutting parameters are set correctly, especially the minimum power for clean corners.

Set the Correct Laser Focus

Accurate focusing is important for achieving clean cutting edges 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.

STEP04

Start Cutting

Use the Frame function to outline the laser cutting area. Make sure the projected frame matches your acrylic sheet and the design stays within the material boundary.


Once everything is aligned, start the laser job. Stay near the machine while it’s running and monitor the cutting progress carefully.

Post Processing

When the acrylic laser cutting is complete, carefully remove all parts from the laser bed.


Assemble the 3D acrylic heart by fitting each piece into place. Once finished, you’ll have a warm, layered gift that is ready to share with someone special.
