Of course you can also build individual letters or anything you like. We are pleased to hear of your ideas :-)

Step 1: Design
Therefor we create a design with Coreldraw.
Step 2: Heart Building
Then we glue them together.
That is the shape of the LED.
Step 3: Wax
Step 4: Embed Form
Step 5: Silicone Fill
Then it is for 15 minutes in a pressure pot. It also works without. But then you maybe have small blisters in the mold.
Step 6: Mold
Then rinse with hot water and dry well. Then all the wax residue from the mold.
Now the mold for the LEDs is ready.
Step 7: Acrylic Fill
When filling make sure that the filling hole is not sealed, otherwise the air can not escape from the mold. Air bubbles in the LED do not look so beautiful.
Step 8: LED Prepare
Then it is dipped into the liquid acrylic.
Step 9: Acrylic Cure
After two minutes the acrylic is pretty tough. Only not under the paper. For this, take off the paper and harden it out for another two minutes.
Step 10: LED Shape and Remove Burrs
Step 11: Surface Paint
But you can also polish the heart-LED, but it takes longer and is much more work.
Step 12: Checking
Still connected to an battery and admire the result. It's waiting to be fitted in somewhere :-)
Have fun to recreate it
