How to Laser engrave on Glass with Diode Laser

[@PawPawsWorkShop]

Thanks to everyone that let me know of a voice over problem. Hopefully, problem solved.

[@JohnColgan.]

Yep, you got it sorted, thank you

[@MarcRCAddict]

Such a cool tip thank you mate, another one I saw was the oven grate tray as a cutting bed? That’s so much cheaper then a honeycomb metal board.. I’ve just got my blue diode 40w 445nm 4.5w atomstack p7 laser, what laser safety Goggles would you recommend?

[@dmanero]

interesting video but how do you wash off the spray paint? what do you use to strip the paint off the glass.

[@andyh8239]

20W laser? (2.5w optical?)

[@3DJapan]

@@dmanero I don't know about glass but spray paint comes off of ceramic tile very easily with lacquer thinner.

[@kennybrooks9357]

Just used a “modified” version of your method. We found that direct contact with our honeycomb bed can cause spotting on the back side of very thin glass. We elevated the glass using magnets under areas that were not being engraved and got beautiful results with your settings. Thanks

[@PawPawsWorkShop]

Outstanding, I'm glad that you found the video helpful.

[@TheLouisianaHobbyGuy]

Tempera paint is self leveling Paw Paw, so if you put it on really thick, it comes out perfect with a roller! Great instructional video!

[@PawPawsWorkShop]

I tried the roller. And it sucked. Went with the brush. Will try the roller again. Thanks. Love your work also.

[@TheLouisianaHobbyGuy]

@@PawPawsWorkShop You have to put a thick coat on. My first time it was see through, but since then, I just use more paint and it comes out perfect. I haven't tried the Rustolium trick yet.

[@allenhuffman]

As I learn my new engraver, one thing I don't often see it the power of the laser used. If I know my Atomstack A5 Pro is a 5W laser, I would expect settings would be similar for a different brand with a 5W later. I'd love to see more information like that in videos of this type. That would be helpful for us newbies trying to understand what settings we need to be using to get similar results.

[@shigerufan1]

At 7:05 you can see his laser is a 20W, so it would be 280% on a 5W.

[@campandcook3118]

@@shigerufan1 actually, 5w/5.5w is just barely eniugh, just needs to run the laser 5-6 times slower. But anything under 5W wont create enough heat.

[@John-of5sh]

Just as many others have said here, I have learned a lot watching your video's. You are an excellent teacher and easy to follow along with. I am more O.J.T. as opposed to reading.

Thank you!!! I am new to the engraving world and glassware was one of our ideas for sets, but I couldn't figure out why it wasn't working as my 20W laser clearly states it works with glass. Now I did notice the laser going through both sides of the cup but, still didn't click that I needed to temporarily paint it.

[@randybranson1009]

Thanks for the video. Yours was concise and told me just what I needed to know without a lot of worthless chit chat. I did a LightBurn materials test and the 30/60 setting gives great results.

[@BillYovino]

When I took a stained glass course, they told us to use kerosene to clean glass. It works great.

[@PawPawsWorkShop]

I have never heard of using kerosene. My wife produced stained glass on a commercial level both nationally and internationally for ten years. She never used kerosene to clean the glass. Soap and water works well.

[@BillYovino]

@@PawPawsWorkShop That's what I was taught and never I challenged it. It does work very well and I never had a problem cutting glass using that method. I think it may be easier than soap and water because it evaporates very quickly and you don't have to dry it. I guess there are many ways to skin a cat - not that I'm recommending skinning a cat :)

[@PawPawsWorkShop]

To cut the glass you should use oil cutters. The kerosene may act like oil when cutting and then clean with soap and water

[@BillYovino]

@@PawPawsWorkShop I've never used oil, Windex, or soap and water in any of my glass cutting over the years. Strictly kerosene and an old tee shirt.

[@berniemarinakis4953]

Kerosene is used to cut glass because it lubricates the cutting wheel. The glass is not clean but in fact oily with kerosene. Use alcohol to clean glass.

[@campbellbluestone1837]

is the purpose of the paint simply to stop the laser shining through or does it also make for more detailed lines?

[@PawPawsWorkShop]

The diode laser does not see the glass. It would go straight through and do nothing to the glass. The paint provides a focal point

[@campbellbluestone1837]

In that case would a piece of black sign vinyl on the underside of the glass not be much quicker and work just as well? I understand that you can’t laser directly onto vinyl/pvc due to the poisonous fumes but with a glass tumbler you could also place vinyl on the inside if it’s simply to block the beam Save a lot of painting, drying then washing or would that not work for some reason?

Great tutorial, unexpected that the brush painting would be so clear. Have you ever tried (or considered) blackening with soot from a candle or tip of a lighter flame? I expect it will need a thick layer of soot.

[@PawPawsWorkShop]

Yes, that did not work.

[@paulramos5732]

You should try a rubber ink roller if you want to smooth out the tempera paint. Although based on your results, it doesn't look like it matters.

That is a good idea but as you said, not necessary

[@thewop655]

Questions for you..... I have a 10W diode laser so do I still use 60% power or should I use more also if the paint is there just so the laser can see something, can you use a black piece of paper instead ? Thanks for this video...

[@PawPawsWorkShop]

You will need to run a grid test to determine the best power and speed. Yes, you should be able to do that with the paper

[@КаксеправиТехнология]

Hello I wanted to ask what software program you use and with what settings you cut acrylic because it doesn't work for me. Thank you!

[@PawPawsWorkShop]

Lightburn is the software. This project is glass. The settings will vary due to the hardness of the glass. You must test

[@janicebrigance1813]

Hello, I am a newbie at this. I have a we creat blue laser 20 w. I use the Make it software and don't use the lightburn. Is it similar?

[@PawPawsWorkShop]

It is similar. With the Make it software you have pre-tested grid for recommended settings. It still will require some testing

[@11RENDON]

I got a question for you Paw Paw, I have the long mill Mk2 30 x 30 and interested in buying there version of the laser. Do you think that with the same parameters and process, I would still be able to have the same effect on glass? Not to sure, kinda new to all this. Thanks

[@PawPawsWorkShop]

The process would be the same. The power and feed rates may vary. That will require a little testing.

[@stacymcvey4229]

Why would some of the tempera paint be burned into the etching of the glass after the engraving?

[@bradlovely6936]

Quick question: Would the 5W Laserpecker 2 perform with similar results, Pa'?

[@TeeganLee]

Can you etch glass deep enough with a diode laser to paint the glass, wipe it off, and have paint left in the etch?

[@PawPawsWorkShop]

The laser basically chips the glass away. It does etch the glass so that you could add paint. Not sure if it would wipe off when cleaning the surface of the glass. Because it etches the glass it may have rough edges and give you a crisp clean look.

[@jitendrathanky3960]

Brillant video - Can you please tell me if you can laser etch the reverse side of a mirror (the coated side of the mirror)

[@PawPawsWorkShop]

Yes, you can. Mirror the image. You will need to test the power and speed on the mirror. Also, use in a well ventilated area

[@jonathanreyespuentes201]

Hey! Great video thank you, short question, how do you think it could work with me if my engraver is 10w. I understand you use 20 w at 60%

For the glass it is the cheapest tempera paint available. This is a common paint used in elementary schools for kids. For the white tile method you need a paint with titanium oxide in it. This usually is found in white paints.

[@ericdickson2248]

When you laser the glass how did you get the white color? I love the project and am trying to learn. I did a pie plate but it’s difficult to see the etching because it’s clear unless I have a dark backround

[@PawPawsWorkShop]

The white color is the glass itself. It’s normal to see the etching better with the black background

[@jbrunson1949]

I would try using a white paint, if you intend on eating on the plates it could be bad idea,, as thhe food and such will get into the engraving, another thing that works on glass or plates, is T-O Titanium-Oxide, comes in powder form and you mix it with anything from water to paint thinners, I used plain alcohol as it helps the drying time, as anything you use it needs to be put on thick, so several coats work better.

@@PawPawsWorkShop Yeah when you said 20w alien laser I immediately jumped over to their site to see what the actual output is. SO many chinesium lasers rate the laser by the power consumption NOT the optical output. Now with that being said there IS a company (I forget which) who developed and just released a diode laser that IS 30w. What they've done is ganged up a number of diodes and then combined the lasers via a prism to make a beam that has all the power of all the lasers combined. No info on when they're going into production or the cost as yet. It was this past summer when I read about it.

Nothing. With clear glass and a diode laser it would just go straight through and not do anything to the glass. You need the paint the glass for the laser to focus on it

[@TalkingGIJoe]

What is the actual engraving power of your laser? 3 watts? Found it... 5.5 watts optical... thanks!

[@PawPawsWorkShop]

On a 20 watt input you generally get about 5.5 watts output

How hard is it to get that primer paint off the glass??

[@PawPawsWorkShop]

This is tempera paint. It washes off very easily with water

[@zozoartstudio4727]

Oh I meant the spray paint you used

[@PawPawsWorkShop]

Just wipes off with lacquer thinner. Very little mess

[@loriniles6888]

Have you tried tempera paint on tile?

[@PawPawsWorkShop]

No, it is a different process you need the chemicals in the spray paint to work

[@colinbarrett5538]

Brilliant tutorial, can i ask if the spray paint you used was oil based or water based?

[@PawPawsWorkShop]

The spray black was just rustoleum and it did not work as well as the tempera paint that I brushed on

[@colinbarrett5538]

@@PawPawsWorkShop I can't get Tempera in Ireland, Is it acrylic based?

[@PawPawsWorkShop]

No, it’s a very cheap paint that is often used in elementary school for art projects

[@MARCELLO6859]

Do you think it is possible to engrave glass with a 10w Sculpfun S30 laser?

[@PawPawsWorkShop]

Yes, you should be able to do this with your laser

[@Dancopymus]

Hello Paw Paw. Is this Tempera Paint the same as the Spray High Temperature Paint sold in stores?

[@PawPawsWorkShop]

No, the tempera paint is the cheapest low quality paint used most commonly in elementary schools for kids projects. Not sure what is the equivalent in Brazil

[@Dancopymus]

Tks; Is it Gouache Paint?

[@PawPawsWorkShop]

I do not know that name
