![Can A Diode Laser Engrave Clear Acrylic?? [YES, but not without this]](http://i.ytimg.com/vi/m_FwZVADOq4/mqdefault.jpg)
Even when something doesn't work out it is a great heads up for the rest of us. Thanks. Awesome light show from around the perimeter of the glass.
Great video! that's amazing how it actually burns the wood underneath the glass!
thanks, and great job u have done,
as u mention that u have 2.5w laser,
can u plz share u software setting for this process?
Haha! The fashionable glasses for the next summer? Nice experiment, mate.
Nice Video! I would like to know if a 2.5W laser can cut thin plastic? (around 0.3mm). Thank you!
I so enjoyed your making of the jig to rotate the bottle. You should have made a video of that. LOL.
Your jig fabrication skills were as much fun to watch as the laser part of the video.
look at those sparking blue lighnings :) it is beautifull :D
I can effectively cut most glass with my NEJE 7w Solid State Laser - as long as there is a black/dark coating on the surface (Dryboard type Markers work) to momentarily absorb the Laser Light/Heat, enough to fracture. I have found that sending a 'Pulsed' Line to the Laser from the computer works, yet when sending a Vectored _Line_ to the Laser, while powered Constantly, results are erratic.
As of present, I have managed to 'Etch' onto the surface of most glass using this method but I took precautions to prevent Laser Light bouncing straight back into the Module, by offsetting the Laser Module at around 10 degrees from square onto the reflective glass surface.
I have a "20 Watt" Module in an Eleksmaker 2 Axis Frame/Gantry type CNC Unit that although Considerably more powerful than my 7w NEJE, isn't as good for recreating Pictures or Photos as there is a narrower Grey-Scale.
My 20 Watt unit is best suited for cutting, as accuracy isn't as important. Beam Quality can be improved by buying/using non-proprietary Collimating Lenses for increased accuracy but as far as Optical Output Power, it is nowhere near 20 Watts - roughly 7.5 ish from cold, and up to 10 with a prevailing wind. I would imaging that most Higher Power Solid State Laser Units would be able to micro-fracture most glass, as long as the Beam is Offset and that a Black Coating put onto the surface to be etched but through experience, anything from 1000mW up to 20W will fracture glass - but Pulsing the Laser as it moves over the work, is far more effective than attempting it with un-pulsed, constant Beam.
That is soooooo friggin cool. I've been cutting glass for 30 years ,(old way of course) and I never thought you'd be able to do it at all because of the heat component. Uneven heat stresses the glass and therefore makes it crack. I'm super impressed and now I want one.
Thanks for sharing your information.
Hey Savvas, try scoring straight across, then moving the score line to the edge of the mdf and pushing down instead of taping the edge of glass when picking up. I.E. the side you score needs downward force applied at the edge of piece, not at the middle where scored.
Hi! Good video! This laser can cut 6mm carbon fiber? Do you know? Thanks!
Are lasers stronger closer or do they stay the same? Is it possible to create one with sun rays?
Which brand m/c u use in video bcs i m surprise to see as a router nd nozzle are join
Hi! Do you have other video cutting the glass bottle?
I hope you calculated the frequency being used so that you wear the correct visual spectrum safety laser glasses.
*NICE SOUNDS!*
I took a course in laser cutting wood and they recommended using paper tape. It eliminates the burn line on wood and acrylics.
what software do you use?
Where can I find the video where you mount the laser to the cnc machine?
I thought for sure it would work! Maybe if it were to hang over an edge, to help distribute the stress along that line during the break? In either case, thanks for the plug. By the way, I love how it sounds so futuristic as it moves.
The sound is from stepper motors. A controller adjusts the timing of the steps to make it accelerate and slow down smoothly.
The bottles are actually pretty hard and thick glass! Nice try though! Thanks for sharing!
+Scrap wood City Maybe I should make the first ever laser band saw?
+Savvas Papasavva lol!
would it be different if you paint it black?
Scrap wood City α
Did you actually cut the glass, or are you just breaking it along the line of thermal stress introduced by the heat of the MDF that was burned under the glass?
Would have been better to not actually break the glass, but rather wait for it to cool, then clean the soot off of the back side, and inspect for actual cutting / melting / disruption of the glass surface.
Ive seen a laser cut plexiglass, they put some sort of backing on the plexi and cut the side with the backing, i think whatever the backing is it prevents the plexiglass from diffusing the laser.
Hello do you try to used to dngravd marble?
possibly drawing on the glass or change what is underneath the glass might help
The answer to cutting the bottle is to rub the heated cut with an ice cube and it will automatically break along the lazered line, you must move quickly once youve heated the glass
we used to cut bottles with a candle and ice cube years ago when it was all a rage to make wine glasses from bottles ,and we would glue the neck portion to the bottom of the bottle, Give it a try Im sure you will have sucess
That so smart laser on a reflecting surface🎉
Spray on some Dry Moly Lube, and let it dry first. I've been able to engrave and etch with my 3 watt laser doing that. Once you cut a pass, use a set of breaking pliers or tapping to split the glass just as if you had cut it with a glass cutter.
When the glass is heated up, try using a wet sponge and go over it. The great difference in temperature will fracture the glass along the heated line.
As knowing if the power that comes with burning printer is telling the
salesman, I bought one of 2500 mW but it does it at any site, is there
any way to check it.
And if the seller has sent me a lower power
laser as I know it, since these are cheaper, in short because not
described the power of the lasers in any site, please if anyone knows
what to comment, thank you
I'd be of the opinion if you used a better edge, straighter, would yield better cut results. Rather than just tap it and hope it breaks on the line perhaps if you aligned it along the edge and tapped downward on the over hanging piece, might make for a better break or cut edge. I've cut glass in the past, not enough to be considered a beginner, but enough to know that when glass vibrates it ripples and breaks where it wants, the scored edge is simply a general guide.
You need to collimate the focal length try a positive convex lens to converge the beam.
start at a crack in the glass you might be able to "steer" the crack around?
Hi i have a cnc router and i want adapt a laser cut how you adapt you laser cut?
the first problem is light passes straight through glass, the second is glass density slows it down a bit changing the rate of induction, the third is glass scatters light especially once it's reflected back up and makes the whole glass shimmer, fourth you're using impact to break the glass... assuming the scorched wood heats the glass then your best method of clean breaking would be rapid cooling. wouldn't your best bet be some kind of mirror array arround the bottle which would effectively draw a laser line all round it by sending the light through from as many angles on one plane as possible? even then it might take loong time for glass to warm up.
Where is the other channel? I want to see more on this laser. Also, Try to put the glass in cold water, the shrinkage should crack it right on the line.
Can You cut glass with laser, that have under a piece of ice ? There will be more thermal shock and maybe can cut easily.
can your laser cnc cut a 1 mm rubber sheet ?
hello
i have 2 questions: how you turn on the laser ?
your andruino turned on a relay and the relay close the electrical circle of the laser ?
is there a delay when the laser gets turned on, can you compensate this with the software, the cnc waits x Seconds when the command to turn is is read ?
meets from Austria
Driver using PWM signal - check out my other channel for controller video.
Hi friend, Can this laser cut 3mm mdf? Thank you
Put all of it fast in water or put a small stream of water just where it had been heated and the contraction of that point would make it break perfectly. However lime glass doesnt have any big absorbent spectra at blue light only like 15% or so.
So would a 2500mw diode laser cut foamboard?
Were so close to inventing the Light saber!
Wonder what would happen if you put a mirror underneath ??Would it cut underneath
to me there is allot of wastage of lazer bouncing all over every where it wants to be
concentrated on one spot only..Plus would be safer..
+Muhaa Haloa Yeah but it looked cool - painting the glass black was one suggestion.
I have a 50w laser and it takes me a while to cut glass letters out. Im surprised 2.5w non co2 will do anything at all.
tienes que hacer una caja de madera asi el laser de costado no rebota, genial tu idea ! gracias
as others have said, marking the glass with black marker would help, and instead of tapping the glass, try dousing it in cold water instead.
if you put opaque tape on the top and bottom of the glass it might work.
It will be heating the tape and not the glass but the residual heat might do the trick.
"2,5kw laser" that would be enough to cut through my house
You should get some running pliers to break along the score line
Hi guy. I did this with a ten watt laser voa accident. I was meaning to inscribe the glass and went at high power at a fast speed and got a clean cut. I remembered half a year later and looked it up on youtube. o7
Haha I did something similar. Etching the side glass panel of a desktop computer case and same thing too much power. Ended up cutting half way threw and whole design that was etched fell out 😂
@@istayhighi1540 oof. A one piece. I feel for Jew. I was calibrating.
noobie here. wont the laser reflect and hit somewhere else?
It looks like it broke along the sides of the hot part. If you heat up the glass, it'll get viscous to some degree, rubbery might be a better descriptor, and the weakest place will be the edge of that, where it's 'transitioning' to truly brittle/cold. It might have been a cleaner break if you'd have done it a couple seconds earlier before the heat had a chance to even out. Heat management (if not thickness) is how glass blowers get clean breaks. What would be more effective with glass is to just score the surface, it's something of a meniscus under tension, to create a weak spot (the higher the silicon content, the more effectively a scratch will cause a break, but it's a whole lot harder to scratch).
What had me biting my nails wasn't the lasers shooting every which way so much as wondering if the laser would heat the glass enough to get it to expand and send the halves, or shards, out to join the laser diaspora. This really needs a "don't try this at home" caveat at the beginning of the video.
You require a shorter wavelength, in the UV spectrum. Or in the NIR spectrum with an ultrafast pulsed laser....
good cutting
can you make a step by step video on making a cnc table top like yours. include parts and all. thnks
Finally a question I can answer - th-cam.com/video/J6ioZm4Zmd4/w-d-xo.html
I'm sure someone else has probably said this already, but. Green safety glasses are for red lasers, You're wearing the wrong type and will damage your eyes if you use these with a 2.5 watt blue laser. The correct colour for protecting against a Blue laser is Red.
at least a 40 watt co2 bro mine dosent just heat up the glass it cuts it if i didnt know better i would think its done with a diamond bit etches good too
You said 2.5 Kilowatt Laser and for a second I thought you were given a Death Star type weapon.
Can it cut metals
You have the gas supply there but not putting it to good use.
Take the nozzle very close to the laser spot. Boost the supply. This will cool the sample very fast. Clear water can also work.
Then paint your sample with something black, e.g. permanent market. A few layers may be necessary. Otherwise, just using the MDF and operating on the underside may work also.
Finally let your beam expand and catch it with large lens with a shorter focal length. It will achieve a much smaller spot size with much higher local temperature.
The temperature gradient between the cooling gas and the heating laser spot will do the job.
Have you thought about a 14 $ glass cutter. To do it in less than 2 seconds ?
What about cutting toughened glass with laser?
1:43 “I will make sure my sleeves are all down” for safety, then goes on playing with the laser with the sleeves up and no gloves.
Do you think its possible to cut through 6mm mdf? I was thinking of getting one of bangoods kits but 2.5w is the highest module laser they have :/
with 2,5 you might be able to cut 2-2,5mm wood. You need more power for 6mm
"I think the heating of the MDF did most of the work"...
Yes I was thinking the same thing. One way or another, it did cut the glass. You might be on to something, Savvas.
+GameraTheBrave Heat and high temperture of trapped fumes.
@@SavvasPapasavva 2.5w laser cut a 4 mm MDF ?
2.5w laser cut a 4 mm MDF ?
Nice experiment. I suppose then to cut acrylic sheets should be a piece of cake with 2.5w laser?
"acrylic sheets" is a relative term since acrylic comes in various thicknesses....plus it depends on whether it is cast acrylic or extruded...extruded is much softer and tends to melt back together when you machine it....
i think for glass better IR laser because glass is opaque for IR spectrum
There's some sense in the comment section after all! :-)
I was about to say the same thing. I don't think an IR diode would cut though. I've seen a desktop 40W CO2 laser that will cut glass.
paul30003 the desktop co2 lasers only really Mark glass not cut it
the IR spectrum is not long enough either on diodes, so you need a CO2 gas laser to get a good long wavelength that is absorbed instead of reflected or passes through with out effecting it,
I am kinda surprised the brown bottle did not have any effect on it though since it has pigmented stuffs inside it that allow heating them maybe, guess they were just not enough though,
like using natural or clear plastic vs solid black plastic of same plastic type you can cut the black but not the clear or even natural, instead when I tested it, it just burned the stuff under it, though I was using a 2.5w 395nm laser not a 450nm like I am guessing he had,
to add I think if we can get a diode laser that puts out a much higher frequency, one that is in the totally ionizing range, or nearer to the VUV (Vacuum Ultra Violet) range, it would work for cutting glass and just about anything else, with enough power :)
ir would show heat buildup at line but because of substaight abd ash reheating. No glass was not cut by lazer but from heat of burn wood.
Hello
Can this laser (2.5W) cut out the plywood (for example 4mm)
No
Try adding some black paint on both sides of the glass it will cut better maybe faster too..
+Savvas Papasavva perhaps you shouldn't tap the glass on the table. Try to dip it on hot water for a minute or two, then wash it with cold water directly.
do what i did mount a 40 watt co2 on the cnc
uhh accidentally stumbled on this, come on 2.5kw meant 2.5W which is piggyback of blue ray players (blue rays have 500mw UV) as to 2.5kW those do exist and they wont cut house apart mainly due to lens properties. CO2 2-4kw can cut your hand on 200mm foco lens but if you fire it to wall it will just set it on fire but not too crazy. Low power UVs are diodes like one in video, higher power are YAG in UV spectrum. If u lift glass in air and focus on it then you will have better chipping away of glass particle with minimum heat. For fun will try same thing with our UVs on higher power.
This laser 2.5w cut fabric is with a good quality?
Haven't tried but will put it on my Will It CNC list on my other channel.
Perhaps it could slice bacon or roast beef and cook it at the same time.
Hi. I have the same laser and please could you help me to drive this laser for my engraving machine? How can I drive this laser through arduino uno?
Hey I have a video about the controller and driver on my other channel: th-cam.com/users/EducatingSavvas Hope that helps.
in the video you say 2.5KW but the module in the link is only 2.5W. you can get a 6w module from DTRs laser shop for almost the same price.
you should try dipping the glass in cold water right after you laser it... Worth a shot
Maybe you put the glass on 2 mdfs with gap under cutting line to be sure if heating of mdf doesn't do anything
Pretty sure whats going on here is the burning of the mdf is whats heating the glass along the line and causing a stress fracture point. If you did this same test with metal underneath the glass would not break.
Apply a jet of cold gas right after the first pass and the glass will break.
When I say right after,,, means the jet will be following the laser, maybe a half cm behind only..
Let me know..
Sorry if some one has said it but the glass is acting like fiber optics hence the light show.
Why don´t you paint the glass surface with a black ink before trying to cut it with a laser? Maybe the black color can to absorve the power of the laser to make heat in the glass on the touch point of the laser! Only a suggestion...
Do you need colored glass to absorb the laser?
+Heavyboxes Well the bottle didn't really work that well... I think I just need a more powerful laser.
Try using a mirror under the glass it may add power to your cut. Just a idea.
Nice video. I have a few suggestions one is to move the laser closer to the target piece. Two beam focus has to be tight. I could not tell from the video how focused the beam was. I worked two weeks on a cnc laser and it was very close to the target and laser beam focus was very small point of light. And never try to cut polished metal. We had a job come in on polished metal with a plastic coating and every once and a while you would feel these burns on your skin just a quick flash when the coating was burned away and the polished metal was exposed. After a few of these we put up panels to block any further problems. This was a small 4x4 laser that was open.
There is a big difference between a CO2 laser and a blue diode laser. A CO2 laser is from a laser tube. The light rays coming out of the laser tube are parallel and use a special glass lens to focus them. The focus is not adjustable because of the parallel light rays entering the lens. A diode laser emits its light rays from a tiny point and the light rays are not parallel. A focus lens is used to adjust the focus and is variable.
Tap the glass score side down it will work better
0:17 - 2.5kW... you wish mate! (hee hee)
From what I have found, an infra-red (IR) laser works well to mark/etch glass and acrylic. IR won't easily pass through these materials because it's frequency (wavelength) is too low. The blue laser on the other hand is about 1/10 of the wavelength and passes a significant amount of that power THROUGH the material... which is why the MDF burns.
I would love to find a 15w solid-state IR laser... that would do quite a bit more. But for wood, paper, etc... the blue laser has been working well for me.
honestly thats y people prefer co2 lasers for that, since the tubes are a lot cheaper than something solid state also u would probably need liquid cooling on a solid state module
@@ShahZahid Actually not true, you can get a 40W blue solid state, air cooled for $290 now. Solid State IR units are now coming out... but still low power and costly.
@@Askjerry im speaking from personal experience i have used a nichia NUBM31T 95watt multimode laser array and even for that module i couldn't get away with air cooling i had to use liquid cooling
Someone GAVE you a 2.5kW laser? That's about £120,000 worth of kit. What cooling did you use? Usually takes 2.5" mains water pumping.
Man u should try with one sided opaque black coating glass, that should be work I guess..🤔🤔
it will ez cut or engrave
Puedes poner una linea negra con un marcador permanente y pasar el laser, e inmediatamente hecharle agua a la linea negra para que se enfrie rapido y se quiebre por la linea por shock termico.... You can put a black line with a permanent marker and pass the laser, and immediately pour water to the black line so that it cools quickly and breaks through the line due to thermal shock
write with black marker on the glass then you will get more result
I have two of these. each mounted in the front and back of my jeep. it's get for removing traffic jams and tailgaters.
Cool video. But I think you got the power wrong in the title? It's 2500 mW, so 2.5W?
+James Williamson aye! If it was 2.5kW it would blow a hole through the table :P
+James Williamson Yep I did, will change that - thanks!
+leosedf The laser obviously effected my mind.
+Savvas Papasavva You will need much higher power to do that. But anyway you can use it for many interesting stuff.
+Savvas Papasavva No worries. Have you thought about getting a lens and a bit of lens tube to get it closer to the surface. Focusing that laser would make it do a much better job on the glass.
you should put a black mark on the glass, it will heat it up much faster
at least someone is smart here haha..
I was wondering why he didn't go for ablation... But then too by definition any coating would be ablated off almost instantly, and also, cutting glass with a 2.5W laser? I think we can simply dispense with all logic here and bust out the glass cutter tools.
even those 1w blue lasers u get off ebay for $50 are bad ass.. u can burn stuff from far away lol... and im sure it would make any attacker blind... sunglasses or not! lol
NightRunner417 Ablation with a diode laser? Good luck with that mate.
You'll need a mode-locking ultra short pulse laser for that to get the high intensity pulses for ablation. Probably around 2J/cm² depending on the pulse duration. That's 2 GW of pulse intensity at 10 ps pulse width. Have fun squeezing that out of a 2.5W laser.
Goodluck finding a 2.5w Qswitched laser.
If the mdf worms up the glas then putting the glas in cold water should break the glas in straight line
"In the Middle Ages
glass was cut with a heated and sharply pointed iron rod. The red hot
point was drawn along the moistened surface of the glass causing it to
snap apart. Fractures created in this way were not very accurate and the
rough pieces had to be chipped or "grozed" down to more exact shapes
with a hooked tool called a grozing iron." - Wikipedia, Glass cutter - I suspect that what's happening in this video is analogous.
Maybe I can use the laser to heat a piece of metal which then drags on the glass?
so cool
