Edge Lit Acrylic

Good looking jellyfish.


Thank you everyone for your positive comments and feedback. Much appreciated. You have given me the encouragement to do something cooler. :star_struck:


I wouldn’t doo too much now as it has no masking tape to it anymore! A quick advice would be just after it finishes the engraving/cutting, do what geek2nurse said with a toothbrush, gentle scrub to remove few pcs and bits that may still be there!

Then, remove the masking tape! Clear acrylic is very easy to scratch and you won’t want it to happen when you will lid it up and show all the scratches around the art! :slight_smile:
Well done!

The photo posted above is my second attempt without the paper backing. Thank you for your advice.

What a perfect design for edge lighting!


Very nice! The glow is perfect for a jellyfish.

I almost always remove masking when engraving acrylic. The masking doesn’t melt, but the acrylic does and when you have detailed engraving close together the melted acrylic can grab onto the edges of the masking. FWIW, masking shouldn’t be needed anyway since it won’t stain. Just be careful in cleaning it as stuff like alcohol and other chemicals can cause crazing and ruin it.


Thank you for the insight. I used a cloth to wipe away the acrylic dust that was left over after the engraving.

A method I use for removing small pieces of protective paper is using a piece of Gorilla Duct tape, the sticky side towards the work. Press it down on your work and peel up. Repeat as necessary.

Brilliant, I will try this too.

I was doing that. And then I found my plastic scraper works REALLY well with minimal effort. I did dozens of acrylic items for all of our nieces and nephews. I started with tape, then tried water (which really helped), then I tried my plastic scraper and that worked GREAT.


I have noted that if I go for a deeper engrave and totally vaporize the masking, I don’t have the issue of melted glue gumming up the works. But then you have the issue of scraping off the masking and that can contribute to gumming up. But then engraving with no masking, especially if you get a deeper or slower engrave, can build up residue from the acrylic. In any case, getting the balance among these things is a personal choice.

But that jelly fish, that certainly would be a trial to remove masking after processing. It looks super.


Absolutely gorgeous jellyfish!

Toothpaste works to get things off. I recommend it for acrylic.

Great job!


Thank you. :slight_smile:

Yes, I have the same pucks and they work fine.

Love this piece!

Thanks for sharing your build…especially the link to the LED bases. Ordered a few sets and jumped into making my first acrylic pieces. First one was my company’s logo. Once I saw how good it looked, I made a couple gifts for friends.


Awesome. I am happy to have been an inspiration.

I created another edge-lit piece. This time for the man who every year cuts my hair and gives me the cleanest, straightest mohawk I have ever had.

Originally the people were vector, but the GF software was working for nearly 30 minutes and wasn’t even finished analyzing the image. So, I converted the vector to raster and it figured it out quickly. As before, I removed the paper from the front before engraving. This time however, the laser left some ghosting around the letters. I used toothpaste to clean most of it off but some still remained. In the future I will lower the engraving power so the etching isn’t so deep. Edge-lit etching doesn’t have to be deep, just slightly etched to refract the light. Note: the raster wasn’t as crisp as the vector.

Michael was surprised and honored to receive this gift. I made it for him because for his 21 year Hair Cuttery anniversary the company gave hime a pin the size of a dime, lame.

Update: I was actually impressed at how far out (left and right) the light continued to glow.


How does your image come out with such detail? I am not tech savvy. This is my first laser and since having it I’ve been doing research. Some one told me to invert my image and another told me to make the image black and white. I have also just tried to etch the original photo with color but all have failed. My only question is how to get that detail because my whole sketch is all white with no detail unless held up against a white background.

Love the jellyfish! Great job! Now I need to make one!

Hi miasiacorinne.

The photo will have to be black & white. You can set the GF to etch everything that is black and ignore the white. Do you mind uploading your photo here so I can see what you’re working with and better help you?
