Fibre Laser Glass Use your Fiber Laser to engrave on the reverse side of glass.

A trick I learnt to permanently engrave a black image or text into glass. It's really easy and the effect is stunning. My 30W Fibre Laser with these settings: Mark Loop 1, Speed 1000mm/s, Power 100% Frequency 20KHz. Hatching - Mark Contour, Hatch1, All calc, Line Distance 0.01mm, Average distribute line

Thank you for sharing your tutorial video!

[@AussieMikesBees]

My pleasure. Thanks for watching. Have fun using the technique. One of the other comments said he used foil. Worth experimenting with.

[@aungmyit1921]

Thank you so much, your solution worked well. Liked and Subscribed

[@AussieMikesBees]

Thanks for watching. Happy to help. Cheers.

[@MediaGrizzly.]

That's awesome! must be fusing the metal and glass almost like welding super cool

[@AussieMikesBees]

Thanks for watching. Yes, it vaporises the metal, fusing the super hot oxides into the glass. Makes a great permanent mark. Fun too.

[@humbertohernandez828]

Nice. Gonna try that for a picture on glass.

[@AussieMikesBees]

Thanks, Humberto. Don't forget to post it for all to see.

[@mcersosi]

Im going to try this right now

[@AussieMikesBees]

Great! Let me know how it goes. Have fun.

[@tedzbug07]

thats cool... Nice one. I only attempted Aluminum Foil on glass prior to this

[@AussieMikesBees]

Thanks for watching, Ted. The advantage of foil is you wrap it around curved glass like a bottle. Have fun with stainless steel.

[@darrinjones9387]

ooh, I gotta try that

[@AussieMikesBees]

Thanks for watching, Darrin. While you’re at it, use aluminium foil too. You can use it on top as well. Cheers, Mike

Thanks for watching, Willy. Glad you liked it. Let me know if there's anything you'd like me to do in a future video.

@@AussieMikesBees I just ordered my fiber laser on the 18th of March. This video is a good find because I bought crystal ornaments and didn’t sell very many last year

[@AussieMikesBees]

You’ll have a lot of fun with your new laser, Willy. There’s a learning curve of course, but we’ll worth it. Personalised products have more appeal and value. Let me know how it goes on crystal. Aluminium foil might be a good option if the item isn’t flat.

[@imranijaz4187]

Woow man u proved it

[@AussieMikesBees]

Hey Imran, thanks for watching. It's always fun trying different techniques. Glad you liked it.

[@MarceloJNader]

Nicely done. My CO2 laser is on the fritz at the moment, so I wondered "Can a fiber laser engrave glass?" By your experiment, I conclude yes and no. Technically the laser went through the glass and stopped at the metal surface and it was the explosion from the metal surface that engraved and stained the glass. Good to know!

[@AussieMikesBees]

Thanks for watching, Marcelo. You’re right, fibre doesn’t engrave glass like CO2. There are different coatings you can apply to the glass before engraving like CO2 does for metal engraving. I haven’t used them so can’t comment on the results. Aluminium foil is an effective medium for fibre both for the top surface or beneath as I did with the stainless. It gives a white finish. Cheers Mike

[@window1999]

How we can marking on glass by fiber laser?

[@jakewidgeon]

Hi Mike, do you happen to know what material you could use under the glass to give a white engraving instead of black? Fun note: I used brass undernear glass and it gives a nice copper look.

[@AussieMikesBees]

Hey Jake, I love the brass idea. Now I’m thinking what other metals to play with. I haven’t tested anything for white, but I wonder if using aluminium and experimenting with settings might come up with a good result.

[@lixinniu5032]

hi Mike, did you figure out how to mark on hard wood without burning much?

[@AussieMikesBees]

Hey Lixin, thanks for watching. I haven’t used the fibre laser for wood. I engrave wood with my CO2 laser with good results. Some woods smoke up more than others, staining the surrounding surface, but it cleans up with a light sanding.

[@cybersechs1368]

Good video Mike!! What laser are you using btw? Is it one of those Omtech variants?

[@AussieMikesBees]

Thanks for watching. I have a 30W Raycus from AliExpress running EziCad2. I’m upgrading the controller to run EziCad3 for better engraving.

[@cybersechs1368]

@@AussieMikesBees Thanks for the reply Mike!! Is that the unit from Richard Z? And the controller card is a "JCZ Controller Card Ezcad2"?? www.omglaser.com/product/jcz-controller-card-ezcad2/

[@AussieMikesBees]

Yes, it is the JCZ card with EZ2. I don’t recall who I bought it from. There were quite a few sellers with the same pictures. I suspect many are made in the same factory. If you’ve been referred to Richard Z then go with that. I recommend spending the extra to get EZ3. EZ2 is notoriously unstable, often referred to as EziCrash2.

[@cybersechs1368]

@@AussieMikesBees Thanks for the reply Mike! Yeah, I've been looking to get into laser engraving/annealing/micro cutting as side business(fellow Aussie here too) so just doing some research. One of the FB groups has different photos of people doing all kinds of crazy stuff with annealing colours on the metals, etc so just researching on what the majority use(for sake of ease/research, and mainly the 'settings' they use) I checked out the Aliexpress site last night, and your right, most of them look very similar. Some of them are much cheaper than what I got quoted, but kinda wary on buying off on that site

[@AussieMikesBees]

I understand your doubts with AliExpress. I’ve bought hundreds of items over the years, mostly cheap components, but still a number of pricey items. I’ve had one non-arrival and one dead on arrival. The DOA I fixed myself, just not worth the hassle of sending back. The no show was refunded straight away. My experience has been good. With your Laser, just make sure you get genuine components. It’s crazy, but there’s Chinese knock-offs of Chinese parts. I know Rock-Solid Laser uses genuine bits. That’s who I bought the BJJCZ EZCad3 upgrade card from. If I had my time again, I’d get one of their JPT M7 MOPA 60W.

[@shadowliving6858]

Wondering if this would also work on clear cast acrylic?

[@AussieMikesBees]

Interesting thought. I suspect it would probably melt the acrylic because there's quite a bit of heat generated in the SS. I'll try it and see what happens.

[@ChuppyCata]

what would be the power setting on a 50w laser?

[@AussieMikesBees]

Thanks for watching. There's a fairly wide range of settings to try and every machine seems to vary a bit. You can start with maybe 20% less than I've used here and see what happens. Have fun!

[@betterbeehives8404]

Are you using a JPT or a Raycus laser?

[@AussieMikesBees]

Hey Aaron, it's a 30watt Raycus currently using EZCrash2. I'm upgrading to EZCad3 as soon as the 2.5D card arrives. Also upgrading to auto Z.

[@shaigt6313]

Hello, we need a help with something and we would really appreciate if you could help us. The problem is we are trying to laser mark Polyamid 6 plastic with 30% glass fiber using our Fiber Laser marking machine, but nothing happens. The machine marks other plastics, but not this one. Can you help us?

[@AussieMikesBees]

You sure have a challenge with that one. I’ve never engraved it and don’t have quick access to it. From what I can find, only a MOPA fibre laser will mark polyamid 6. You could experiment with coatings like Cermark or aluminium foil. Engraving the coating might make a permanent high contrast mark after the unlamented material is wash off.

[@printingcart5889]

Hello Mike, how we can do it on glass cup, like wine, whisky glass? Thank you

[@AussieMikesBees]

Good question. I haven’t done that yet. I would try using foil around the inside of the glass with some foam to help press it against the glass. The marking will be on the inside, so the question is, does the liquid react with the metal oxide? It’s possible to mark the outside by wrapping the foil externally. I think I’ll have to play with this.

[@MrHoelzi]

@@AussieMikesBees did you ever play with that? :)

[@AussieMikesBees]

No, it’s been hectic. I haven’t done any lasering for months. Maybe I’ll find time during the Christmas break.

[@AB-wv1bs]

What type of stainless...303 / 304 ? etc

[@AussieMikesBees]

Thanks for watching . I mostly have 304 and 316. This is a very flexible technique. I think if you can mark the metal black, the glass will take on black. Use aluminium for white.

[@maysam70]

is this machine engraving on wood, metals and gold ???? what is the price of this machine????

[@AussieMikesBees]

Muhmd, thanks for watching. Fiber lasers aren't good at organic materials like wood. CO2 lasers are best for these. Fiber is perfect for metals including gold. Chinese machines start from around US$1500. Check them at AliExpress

[@EJSVARZ]

Hi been wanting to buy one of these fiber lasers for gold. Only questions is how long can you use it for in one day and does it need any maintenence?

[@AussieMikesBees]

@@EJSVARZ thanks for watching. I don’t think there’s a limit on the duty cycle. You can run them all day long. The only maintenance is keeping the lens clean. Much less work than my CO2 laser with mirror and lens cleaning and aligning. Fibre lasers have a very long life, so you’ll have plenty of opportunity and time for it to pay for itself. My only regret is not buying one sooner. All the time and expense of using Cermark with my CO2 laser would have easily justified the purchase, but I didn’t even know fibre existed then.

[@EJSVARZ]

@@AussieMikesBees thank you for the response! This is the the 50w laser right?

[@AussieMikesBees]

@@EJSVARZ No, mine is 30W with a 200mm lens. That’s been more than enough for me. If you want to engrave larger item, you may need more power for the broader area. I see on the group many people do very well with 20W.

[@NAV3DP]

I use foil

[@kwachuskwach9698]

You use 100% black foil, put on glass, markt and put down foil ? It works ? Can You make video ? Thanks !
