I painted the front of the glass with the Tempra paint using a foam brush. I dried it with a heat gun. Ran it on Ortur Laser Master 2 Pro 20W at 1000/100 254DPI and it came out absolutely perfect. Thanks for the great video.
So is the painted side of the glass what is on the surface closest to the actual laser when burning or do you put the painted side down so the laser actually travels all the way through the glass before hitting the paint?
I have the paint face down. I did this so it was trapping any heat between the layers. It also reduces smoke in burning off the paint. Not sure it has to be that way but that is how I did it in the video.
I just washed a guy engrave glass similar to what you did, except he painted a sheet of steel with a gray primer and put it on the table paint up. Then placed the glass over it, It looked pretty good to me but I am very new to lasers. Lots of ideas to try.
You can also use a Black Sharpie and after finishing just spritz with alcohol and it'll come right off. Then you can use the sharpie again on the cut surface and spritz alcohol on it again and only the burnt part will remain colored.
I tried the same technique with a polished stone slab (some sort of igneous rock) at 250 mm/min (probably WAY slower than needed) and it worked flawlessly. Painted side up for obvious reasons (opaque stone).
wao, why i didn´t found this method before for engraving clear acrylic with a diode laser, so great, is possible to cut clear acrylic with this method and the diode laser too?
Just I just made a glass engraving where I used "white titanium spray paint" and with 60 in power and 768 in speed in LightBurn So I can only recommend testing with white titanium spray paint and then it is not necessary with 100 in power. I have tried the tempera paint, black spray paint and even rubber paint but now i only use white on glass and titles. much darker in the engraving. Easy clean off with steel wool and warm water.
It's actually a silicone mat. amzn.to/3U0qHr0. The wood i have underneath started looking sketchy. These work good and non conducive and chemical resistant. So just seemed like a win. They sell a blue one but looks like it may be sold out. It's just silicone so I'm sure another vendor would have it in a size you could use.
It looks like you got a pretty opaque coating on there with the Prang paint, I tried this with Dollarama Studio Colours tempera and I just could not get anything close to an opaque coat with either a brush or the airbrush, I'll see if I can get my hands on some Prang paint and try again.
Rustolium mat black spray paint works great. I set my power at 70 and speed 1000 and got great results. You want to use your laser at 100 as little as possible.
The one I used in the video I purchased through adobe stock but any SVG file will work. stock.adobe.com/images/vector-chicago-skyline-design-with-typography/98205681?prev_url=detail is the one I used specifically in the video.
They tried to switch the US to the metric system in the mid-1970's. People just wouldn't go for it, so the idea was abandoned. Now that I'm older, it seems like a much better system.
Hello, Thanks a lot for sharing this video & information; Is there a technique good enoguh to mark on Aluminum with these type of lasers ?, I got a Neje 30 W engraving systema and can not make it work with aluminum. Thanks again !
I actually got that at the dollar store. It's just a cosmetic cotton ball pump women use for nail polish remover aka acetone. Can get them almost any pharmacy or big box store.
I actually managed to make this work with the Norton method -white paint on top surface of clear glass- and got decent results too. I'll have to try the back face to compare results. Thx for sharing.
Apologize if this info is somewhere, but I did not see a link to the name and type of laser device you used in the video notes. Would be nice to know the brand, details etc. Thanks.
Cool! Does anyone know if you can use painters tape or masking tape to etch glass with a diode laser? I saw a video where they used painters tape or masking tape to etch the glass with a 40 watt Co2 laser.
I've not tried it but I would guess it not as effective given the blue wavelength. You could use this and masking tape though if you wanted finer details. The Co2 operates at a different wavelength compared to the blue allowing you to do more with it.
@@MakersMashup Thank you and cool video by the way! I'll paint the glass and if I want to try the tape, do I put it on the unpainted side? I am new to the whole laser world and recently bought as Sainsmart 3018 Prover with a 5.5 watt diode laser and looking for projects to do and this seems like a really amazing one to try!
Be careful with other paints and offgassing. I chose Tempra due to its nontoxic nature. Acrylic has a lot more chemicals in it and generally not nontoxic. Just be safe.
i've try engrave on glass using tempera paint for about 6hours. and result pretty good. but got problem when try to clean tempera paint. its not cleaned 100% on some point. how i can totally clean the tempera paint and make glass not look dirty cz of tempera paint?
Tempra should clean off with water and dish soap without any issue. If you're still having trouble I suggest maybe a toothbrush to clean out any paint residue but tempra is chosen specifically for its ability to wash off in water. Perhaps the brand of Tempra you're using has other additives not in a traditional Tempra.
Hi, Thanks for your great video, and I would like to ask, what is the surface that on top of it, you put the glass? Why aren't you using a metal / aluminum board? Thanks again.
In the video I used a piece of ceramic tile. I don't like using a metal plate because of the reflective nature. A pin board would be optimal but until I build the enclosure for this machine it will likely be something more adhoc like the ceramic tile.
Ive heard of the galvanized paint suggestion as well. Works like a marking spray. I would use caution if you try it. I've seen many people try different materials in a laser but what I think many people overlook is the off-gasing that occurs. I personally have no idea what chemical process happens when zinc and the other chemicals in galvanizing spray become superheated by the laser. The gas it creates could be dangerous. So if you do try it I would use caution and make sure you have plenty of ventilation. Even if the gas itself is not harmful you don't know if it will leave particles that are harmful in the shop. Lots of variables to consider. Stay safe!
Honestly, not sure. I did it with whatever cheap glass was in a dollar store picture frame but hardened might require more effort. If it works for you please let us know.
Some have used it with success but my caution is that when you hit spray paint with a laser you're off-gassing any number of unknown chemicals. Tempra is generally made from non-toxic chemical so a safer option than spray paint. So while possible, I don't recommend it for those reasons. Spray paint is also harder to remove and usually requires a solvent vs. water.
I found your videos so useful 👍🏻👍🏻👍🏻 Im new to this field can u please advise which machine should i buy for metal, glass and plastic engraving on flat sheets and tube of up to 24 inches in length Thanks
I'm using a airbrush and Prang tempura. How many coats are you using? It definitely isn't covering very well on the first coat. Great content by the way. Very informative.
Does anyone have a recommendation for a mainboard that will allow me to control my diode laser with PWM function, as well as the dual y steppers and the X stepper. Plus the rotary stepper and finally a z axis if I plan to add one down the road?
Any mainboard should provide PWM. The heaters of any mainboard provide PWM. You could probably get away with an SKR, Use the E0 and E1 for your dual X/Y. The Z on the SKR can handle rotation.
I haven't tested that yet but it is on my list of things to try out. If I can be successful with it I will post a video. If you decide to try it let me know of course I'm curious as well. :)
On this same question I have been trying with a kids washable paint and then the settings that you were using but it cracks the glass and doesnt really etch. But if I put a piece of wood under the glass it just burns through the paint. Where is my problem?
I think I missed something...does the painted surface go up or down when you're engraving? Looks like it was down...which aligns with the comment about spraying the inside of a glass.
First of all, BOTH thumbs up for your very informative and interesting videos! XD I only have a HUGE problem here in Germany and unfortunately I write with the translator ;( So: I have the Atomstack x7 Pro 50W Laser and NO MATTER what I do and set I do NOT get it engraved on glass ;( ;( ;( What the hell am I doing wrong? Could you possibly help me in any way or find out if I can really laser glass and stainless steel and aluminum with my laser? THANK YOU SO MUCH in advance from Germany XD Frank PS.PLEASE do keep it up with your videos XD
Thanks for the decent demonstration of marking glass with a non CO2 laser. Any ideas on bottles or drinking glasses? Any reason you didn’t use vectors?
Thank you. Is the washable paint black or any dark colored? Since you mentioned in the other comment the painted side should be down touching the ceramic tile, you focus the laser at that level?
Yes, focus it at the tile you use as a waste board with paper or something similar. I use those metal business cards. Darker colors should work fine but black of course absorbs more light.
Not sure what I did wrong but my glass exploded. I didn't learn my lesson, so I did it again with the same exploding result. I used black black paint with 5w laser. Maybe I went too slow?
Hi guys I have 3 lasers, 40W, 50w and an 80 W, the last two with 10w output power and I cant make engraving on glass. I dont know what Im doing wrong but it is making me crazy
You're looking for this PRIMO Tempera School Paint for Children, 1000 ml Bottle with Dosing Cap (Black) www.amazon.de/dp/B00GIH1C8I/ref=cm_sw_r_awdo_J1FB99W55WGDENQM56AC
Non-toxic when not contaminated with food poisoning causing bacteria. I saw a recall of tempura paints before. Not a criticism of you but of our reigning masters
I chose tempera because it comes in non-toxic forms and was washable. The tempera is easy to get off the glass once you're done engraving. Acrylic will likely take something like acetone to get off however acrylic should work. How well it works though I haven't tested. In my experience acrylic is rather smelly coming off the laser. If you're successful with a different type of paint let me know. Would love to hear how another paint worked.
Oh! You might get away with a Navy but you want a color dark that absorbs light well. While I didn't try white Tempra I've use other light colored paint experiments and dark colors work best when trying to remove the paint.
Hello. Excellent tutorial and I did subscribe. I'd like to know what's a lasers minimum power output to achieve these results? I'm totally green with CNC lasers and I'm learning from awesome folks like you. Thanks again for sharing.
Its honestly going to vary based on the type of laser. Best way to answer the question you're asking is by running a test with your particular laser. A quick line or pattern test should let you see the lowest level that makes a good mark on the glass.
Trisha I really didnt measure it (which I should have) I just thinned it out to the point it would flow easy through the air brush. If I had to guess I would say about 1:1.
So is the painted side up or down?
Down
@@MakersMashup is it possible to laser print other languages than english
That would be a question for the lightburn team but I would think it would be possible.
@@MakersMashup ok thank you but I have another which is how much can i buy the laser printer you have

Good call out. I do something similar with metal stamping.
I tried the same technique with a polished stone slab (some sort of igneous rock) at 250 mm/min (probably WAY slower than needed) and it worked flawlessly. Painted side up for obvious reasons (opaque stone).
Russel, thanks for the feedback and great experiment. Its great to see this approach can be expanded to other materials!
When you laser etch glass it doesn't melt the glass it actually fractures tiny pieces of glass from the surface.
What is the wattage of your laser?
5.5w true output its in his build video
Very nicely and crisply done. I feel much more comfortable etching glass thanks to you and your work,! 😊
What were the lightburn power and speed settings pyou used and what is the power output of your laser
Can this same method be used for clear acrylic engraving?
I use dark paint tape or black marker... Or both...
Awesome video! I’ve watched just two of your videos and they have been very educational. Thank you for making great videos, very informative!
This is awesome sauce! Great job!
wao, why i didn´t found this method before for engraving clear acrylic with a diode laser, so great, is possible to cut clear acrylic with this method and the diode laser too?
If paint is bottom side, how is focus affected ? The thickness on glass makes a difference to the painted area ?
What watt laser are you using
Will this work with borosilicate glass?
How many values set Line interval?
Just I just made a glass engraving where I used "white titanium spray paint" and with 60 in power and 768 in speed in LightBurn
So I can only recommend testing with white titanium spray paint and then it is not necessary with 100 in power.
I have tried the tempera paint, black spray paint and even rubber paint but now i only use white on glass and titles. much darker in the engraving.
Easy clean off with steel wool and warm water.
What output power is that laser you’re using. I’m looking at adding one to my 3018
What are the specs on you laser head?
I love that color blue on the table. Where did you get it? Is that a blue screen?
It's actually a silicone mat. amzn.to/3U0qHr0. The wood i have underneath started looking sketchy. These work good and non conducive and chemical resistant. So just seemed like a win. They sell a blue one but looks like it may be sold out. It's just silicone so I'm sure another vendor would have it in a size you could use.

Wondering how well with the frosted glass do with leds and a shadowbox. Hopefully just as well as with acrylic.
Good idea I might try that. Lots of neat options there.
Rustolium mat black spray paint works great. I set my power at 70 and speed 1000 and got great results.
You want to use your laser at 100 as little as possible.
would it be possible to use this technique to engrave on acrylic?
Possibly. I havent tested it myself but for engraving this should work on acrylic. Cutting is a different story.
Good day.. Can I use this Tempera Paint method for acrylic glass? thanks in advance
Is the silhouette you used , a silhouette you edited or one you purchased? I have a fie with a lot cities but none like you used.
The one I used in the video I purchased through adobe stock but any SVG file will work. stock.adobe.com/images/vector-chicago-skyline-design-with-typography/98205681?prev_url=detail is the one I used specifically in the video.

should I apply air assist when engraving glass?
Yes, you'll still want to blow off any smoke from the tempera or any residual glass grains from the engraving.
Very interesting. Will give this a try. Have you tried using the Norton method on glass? I’ve only ever tried it on tiles and get some great results
What exactly is the Norton method?
Hello, Thanks a lot for sharing this video & information; Is there a technique good enoguh to mark on Aluminum with these type of lasers ?, I got a Neje 30 W engraving systema and can not make it work with aluminum. Thanks again !
Check out cermark marking spray. Won't engrave but allows you to mark on aluminum easily.
you can also use paint in spray can to paint your glass or acrylic.
Sure just takes a bit more to get the paint off.
Do you lay the plate paint side down or paint side up?????
Paint side down. Touching the tile. Although either should work.
I use Cermark black marking spray when I'm selling Custom Glasses. They are dishwasher safe. Spray on, laser and wash off with my xtool D1.
I've used it as well. Good stuff I just wish it wasnt so expensive. They do have a white available as well although I havent tried it.
If you slow the laser down and power up, will it cut the acrylic?
Interesting! What's the ratio of water to the tempera paint? Thanks!
Doesn't matter as long as it's thinned enough to go through the airbrush
Interesting technique. I have a 20watt laser and an airbrush arriving tomorrow.
can we do the same engraving on trasnparent acrylic sheet too?
Others have reported success using acrylic in the comments.
Ok thank you so much
What paint is used
thanks for this demonstration. would you link the product information for the hand pump acetone used to clean the glass? I haven't seen that before.
I actually got that at the dollar store. It's just a cosmetic cotton ball pump women use for nail polish remover aka acetone. Can get them almost any pharmacy or big box store.
Would this technique work with a sculpfun s30 with a 5 watt laser module?
Possibly, it really depends on if the laser can heat the paint/glass hot enough to fracture it. Id give it a try.
@@MakersMashup I sure will.
Thank you.

I seen a guy on youtube use blue painter's tape for etching glass.
How do you get the large etched surface so uniform?
When I do it I seem to get horizontal or vertical lines despite working at a 45° angle.
Sounds like a calibration issue. Check your steps per mm.
@@MakersMashup Thank you, will do that.
I’m new what’s the ratio of water you add to the tempura paint
I didnt use a specific ratio. Just thin the paint enough to easily flow through the airbrush. You want smooth even coverage.
For me a brush with acrylic color, even almost wet was working for me with Atomstack 40W Laser. Results are great, also your Video was very helpful.
Be careful with other paints and offgassing. I chose Tempra due to its nontoxic nature. Acrylic has a lot more chemicals in it and generally not nontoxic. Just be safe.

Great video. Does the diode laser also work on acrylic glass?
It will engrave glass and it can be used for black acrylic but you really need a CO2 laser for clear acrylics
@@MakersMashup thank u for your answer.
is it possible to use alcohol wipes as opposed to acetone to clean the glass?
That should work equally well.
can it be done on a drinking glass? like painting the inside of the glass and laser on after
In theory yes. You'll want to build or use a rotator to turn the glass.

sir may ask what website were u using at 2:11 because im a newbie please answer
That's not a website that's lightburn.
what is a tempra?
Nicely done. Can a hairdryer be used instead of a heat gun?
Probably. Just slower.
i have a question can we put led lights under the glass to glow it up?
Once it's off the laser sure. Great idea.
What are the proportions of tempera paint and water that you used? Those came out really nice
Just thinned enough to spray evenly out of the airbrush. Wasn't very scientific about that part.
What about 50w fiber laser? Can it engrave glass like this, too?
It should. Give it a go.
i've tried the 3018 cnc 5.5 w laser it just burns the paint off any idea why? it's a blue laser thanks.
Check power, speed and focus. If you can punch through 2mm wood this should be no trouble for the laser.
What machine model is it or what brand? I need one that engraves flat glass
That machine is the L301 you can build yourself. Just look at the other videos on my channel.
Love the video how much water did you mix in the paint ?
Just enough to thin the paint to flow freely from the airbrush.
@@MakersMashup Ok thanks

Any mainboard should provide PWM. The heaters of any mainboard provide PWM. You could probably get away with an SKR, Use the E0 and E1 for your dual X/Y. The Z on the SKR can handle rotation.
When you Engrave, is the paint on the Back Side, Down Side, Other Side of where you are Engraving?
the ink is face down against the tile waste board. The laser goes through the glass and then hits the pigment from underneath.
Very good Makers Mashup. Appreciate it. Keep up the Great Work on the Videos and have a Wonderful Day.
Would this work as well on acrylic plastic as it does on glass?
Or would the heat warp it?
I haven't tested that yet but it is on my list of things to try out. If I can be successful with it I will post a video. If you decide to try it let me know of course I'm curious as well. :)
Yes it will work fine I have tried tape and a weekly magazine with good results I have also tried whriteboard maker with good result
can i do this engraving to a magnifying glass?
I don't see why not. Might be challenging getting right focus but I would think it would work.
Any recommendations on speed and power settings, I am using ortur 20w(5.5)
Start with 80% and 500m/min and go from there. I'd try a few test lines before going all in.
I use the ortur 20watt and do glass at 800 mm/m at 60% power.

Non-toxic when not contaminated with food poisoning causing bacteria. I saw a recall of tempura paints before. Not a criticism of you but of our reigning masters
Does it have to be black Tempera paint?
I chose tempera because it comes in non-toxic forms and was washable. The tempera is easy to get off the glass once you're done engraving. Acrylic will likely take something like acetone to get off however acrylic should work. How well it works though I haven't tested. In my experience acrylic is rather smelly coming off the laser. If you're successful with a different type of paint let me know. Would love to hear how another paint worked.
@@MakersMashup I believe that the question was regarding the color of the paint, not the type of paint.
Oh! You might get away with a Navy but you want a color dark that absorbs light well. While I didn't try white Tempra I've use other light colored paint experiments and dark colors work best when trying to remove the paint.
Hello. Excellent tutorial and I did subscribe. I'd like to know what's a lasers minimum power output to achieve these results? I'm totally green with CNC lasers and I'm learning from awesome folks like you. Thanks again for sharing.
Its honestly going to vary based on the type of laser. Best way to answer the question you're asking is by running a test with your particular laser. A quick line or pattern test should let you see the lowest level that makes a good mark on the glass.
What is the paint:water ratio?
Trisha I really didnt measure it (which I should have) I just thinned it out to the point it would flow easy through the air brush. If I had to guess I would say about 1:1.
The ratio is kind of irrelevant because you are removing the water by drying it. Just get it mixed to the texture that spreads well.
