Title: A few pictures of acrylic engraving
Post by: chgames on May 23, 2017, 09:58:59 AM
The photography is terrible, but here are a few things we've been doing with T2 Laser.

We engrave on acrylic.  Then we put LED lights to edge light.  These are early examples.  The 'Classic Home Gamerooms' photo in particular shows how badly fingerprints show.

The acrylic sheets we buy have brown paper.  The laser burns the paper.  We have used transfer tape (used by vinyl graphics people), and spray painted the tape black.  This gives good results, but if there is a small air bubble it will leave a gap in the  completed image.

T2 Laser has been working great for us!

We are using the 3000mw kit we bought off eBay.

Power 255, speed 30.

These are great. I'm actually surprised how good the results are using a 3W diode.

Have you found any colors that work better or don't work at all?

That is sweet! so the etch is on the back side where the black tape is or on the top?
Wonder if my 2.3 will be able to do that or not.

As far as colors... bright colors are... brighter.

Due to the way the human eye perceives color, green is very nice.  Blue is good also.

We buy the RGB led strips with a controller that allows all colors, mostly we have these on display flashing various colors in sequence.

You get best results when you burn the back side of the acrylic.  This means that the design is reversed during the burning process so that it looks good from the front.

The transfer tape that we paint black (It's basically masking tape that is twelve inches wide...) is placed on the acrylic, we burn the design backwards, then the transfer tape is removed.  The brown paper that is used as a protective film works better than transfer tape.

oh so this is clear acrylic and colored LEDs?  I think most of us assumed it was colored acrylics and white leds.

Yeah, I did... but this makes more sense and you can change colors! Awesome.
