If you dont understand something i'm sorry cause english is not my native language

1. First you have to get the desing on the plexi, you always use the back of the plexi not the front so you have to get the desing backwards like a mirror, i did this printing the letters put then (letters looking to floor) on a glass top table then i use a lamp under the table to see thru the glass and with a pen or marker write it in the plexi.

You get this:

2. To frost theplexi i use my dremel with a grinding bit, just use the dremel like a pen to grind all the desing.

3. just put some light on one side, just in one, cause if you use more than one side it will not be iluminated.

And there you have a brand new desing for your car, home o anything you like, try to do it befero on any extra piece of plexi so you get practice and do a great job on your final project.

Looks great!

Don't be worried about your English. Sadly, you type better than 98% of 13-19 year old kids who grew up speaking English as their first language. I applaud you for this.

can you use some type of chemical to get a similar effect?

I have read that you can use some kind of paste of spary to do this, but is a little more dificult, cause you have to cover all the plexi with tape and cut your desing so the only thing without tape is the desing then you aply the pate or the spary following the instruction of the product and there you go.

In my country i cant find any of those product, so i prefer the tool metod, and you always can ask for your neigbor dremel :P, and you'll no take to much time doing this, i take about 1/2 hour.

yeah, back when i was a kid i did a glass etching using a chemical treatment.

drew the outline onto some contact paper, cut it out with an x-acto knife, stuck it onto a mirror, and just smeared on the compound (hydroflouric acid i believe).

washed it off the next day and it was etched.

i'm sure something similar could be done with plexi-glass using a less abrasive compound. i'd check any craft store.


btw, to the op: your etching looks great!

EDIT: not sure how soft plexi is, but a lot of ipod users have used a brillo pad to give the back of their ipod a 'brushed steel' look.

a lot of them have even done a patern (using contact paper or similar) and it's turned out looking pretty cool.

not sure if that'd be rough enough to get the desired look on plexi, though.

As for the chemical etching, I have some glass etching compound that worked great, on glass. Tried it on plexi and it didn't work.

You can see it on the last pic, i use some cheap led of ebay, just have to put then next to the plexi and there you go.

Hydrofluoric acid will do the trick if you go that route but it is extremely dangerous and should be used with the utmost caution. There are easier ways such as using an etching cream from etchall, and you can always try scuffing with sandpaper, sandblasting (which was already mentioned), da sander or a dremel as he did… nice work btw!

Very nice work. That looks great. I use a lazer engraver to etch plexi. Nice even finish every time. It also cuts plexi for shapes and logo's for grilles or amp racks and such.

True enough. You should be able to use a router to do the same thing also. I know a lot of you guys have routers.

A complete sheet might be expensive, but you can get the size you want, look on ebay there you'll find a lot of sizes

Very nice. It looks good

I've done this in the past with sand blasting and I was very impressed with the results. I cut a "stencil" out of a fairly thick sheet of rubber with a computer plotter/engraver. Then you glue the stencil in place on the piece you're frosting and have at it with the sand blaster. It turned out nice and even and overall didn't take long either. I don't really trust my dremel hand either.

A neon cathode will work well too.

I've used neon cathodes to light up my plexigalss chair mat and it looks pretty sweet at night....

whats a neon cathode, when ever i do any lighting i usualy make led srips with 5000mcd LED lights, it works really well and its cheap,

are neon cathodes brighter or cheaper or whats the difference?

Very nice man , Your hands are steadier than mine :) Vinyl templates and steel wool work pretty good as well . I also polish the edges of the plexi with a torch , then paint all of them except where the leds are white . Gives it a pretty cool effect :)

With a dremel it seems like it would not give you an even "pattern" to the etching. This could be a good or bad thing depending on what you are going for.

The best uniform frosting would come from sandblasting or chemical etching.

For an art project I just taped off the acrylic sheet and sanded with some high grit sand paper.

You can use the negative portion of a vinyl sticker if a logo is needed. Make sure to tell the sticker guy to invert it so the sticky is on the right side.
A sandblaster is the best tool if you want a consistent etch
