Step 1: Place Your Acrylic for Laser Cutting
Choose a red acrylic board on the laser honeycomb bed. You can also change to any colour you like!

Step 2: Open the 3D Acrylic Heart File and Check the Laser Cutting Settings
Import the 3D heart design in LightBurn and check if your acrylic size is large enough.
For laser cutting 3D heart with a lot of elements, ensure there are no misalignments or unnecessary overlaps in the file. Double-check everything, and decide if you want to add or subtract elements according to your preferences.
Ensure that the parameters are set correctly:
If the min power is too low, the cutting corners will not cut through; if the min power is too high, the laser cutting will be bad at the corners.

Step 3: Focus on the Acrylic
Without focusing, your outcomes may fall short of expectations. So before starting, make sure you’ve rightly focused.
For focusing, you have two options: Auto Focus, which is simple—just press the AF button on the Thunder Bolt screen. Then you’re ready to have a laser cutting.

Step 4: Frame the Design and Start and Cutting
When you click “Frame”, the red light will display the laser cutting area. This is a safe process, and the frame will align with the acrylic. Once aligned, simply press “Start” to begin the 3D heart laser cutting with the Thunder Bolt!

Step 5: Monitor the Laser Cutting Process
To avoid any issues, carefully monitor the laser cutting, especially when unusual conditions like alarms arise.
Considering the laser cutting energy, for safety reasons, we advise against staring directly at the process, even with the laser door closed.

Step 6: Assemble the 3D Red Acrylic Heart
When the acrylic laser cutting is completed, it’s time to get the parts out. Then it’s just a fun assembly time to get the ideal 3D heart. Imagine the joy of assembling it, as each piece clicks into place to create a warm, layered gift.
