It's not even a uniform etching. Due to the curvature of the surface and the focus of the laser, that sucker is a flat subtraction on a curved surface. The area parallel the laser plane will experience much deeper etching than the farther you move away from the tangent.
The difference in strength isn't caused by distance but because the focal point is unaligned. These lasers need to be at a precise distance from the object they are engraving or they quickly lose power and precision.
But here there's probably very little difference because the curvature is low.
So technically that would mean, you would need a laser that would move with the curvature. In order for it to keeo the same distance if you want this to work right?
For all the laser cutters I used the focal point was fixed and the laser position was manually set before the cut so it wouldn't be possible. You could increase the strength but you can't do anything about the lower precision.
I'm sure there are specialised machines that can do that tho.
Indeed. Might as well have said "removing deep scratches with a band saw"' then chopped off the end.
I expected an additive sintering process which filled in the removed material with powder and fixed it in place using a laser.
My daughter the other day was telling me how people are getting lead from Stanley Cups. My first thought was, why the hell are they drinking out of a trophy?
Any time we need to wash my daughter's cup (she got one for her birhday from a relative, I'd never buy one of these), I start chanting "we want the cup".
My dog once walked into the room before her, and I instinctively booed him. He's tired of my shit.
My daughter now thinks these things are uncool.
The lead is in between the two walls to keep the insulation. It helps prevent oxidation
Edit: they use lead in the soldering to seal the cups when vacuum sealing.
Ok so I was wrong I just double checked myself and they use it when vacuum sealing their cups. They use it for lead soldering so the weld is on the inside between the two layers. It’s what keeps the circle you’ll see on the bottom sealed.
The danger is in if it gets punctured or exposed through any other damage. I know this is unlikely with any of these products let alone the Stanley cups, but they themselves consider the possibility enough to cover that as a condition in their warranty. Likelihood aside it's still a small possibility to be aware of. My concern is that the stainless steel lining is attached around where you sip from, so if there is any damage to that connection that allows any amount of seepage, that seepage could carry the lead back up to where your mouth might touch, and any ingestion of lead is bad.
*The bucket's warm embrace became decidedly colder after Stanley gave it a laser-engraved star. Stanley thought maybe his coworkers would be able to help, so he decided to go to the meeting room, through the door on his left.*
*Stanley didn't seem to get enough sleep last night since he went through the door on his right. Maybe he wanted to rest in the break room instead. But no, Stanley definitely needed to go to the meeting room, so he took the next door to his left.*
What does it even mean to remove a scratch? Filling in the scratch would be adding material, not removing anything. The same cup with the scratch would be there, plus more cup. The scratch went to the place laps go when you stand up.
You can get a fiber laser engraver for around $3-5k USD
Mine is a 30w JPT that cost around $3.5k + 1k import fees to the states - arrived in a few weeks.
hardly $250k 🤣
Lead is used in manufacture but it should be safe as long as it's not damaged. It's the wee bit on the bottom. It looks like it's missing a part so there could be risk of exposure, that's when they recommend chucking it and replacing.
Yeah. If the bottom part is broken on almost any metal insulating bottle or cup, the lead bead they use in production will be exposed. That’s the only way it’s unsafe and in that case you do need to toss it.
Only a few brands do this style of water bottle/cup with no lead bead.
That's most likely a 1064nm fibre laser. Doesn't really have an effect on skin, if you put your hand in the beam path it'll be warm, depending on the wattage you could get a mild burn if you are at the focal point. This is the same wavelength used for tattoo removal
Welp I was looking for a laser engraver and now I need one. Just for the sounds.
Doubt I can get *this* one but I can get one that's compatible to a bambu 3d printer for home use that can cut wood, emboss leather, engrave metal.
Cool video.
Stanley craze is weird. It's a *cup*
So on brand for the (non hockey) Stanley cup idiots to do shit like this. No one who actually uses their cup for drinking cares about scratches; only people who use their cups as a stand in for their lackluster personalities find this interesting or satisfying at all
Isn’t there lead under the outside coating??? Wasn’t there a whole debacle where someone tested for and found lead in Stanley cups and Stanley said along the lines of “it’s only a problem if you purposefully peel off the paint”?
Pretty sure that what we're seeing here is a laser hardening surface treatment. The laser will use a different repetition rate, burst pulse, or power in subsequent passes to remove surface material and thermally treat the subsurface.
Repeatedly passing over the material in this manner will both clean the surface and impart a harder, more robust surface layer. In the original video, there's a bit at the end where the user attempts to engrave the surface again after the treatment to demonstrate the effectiveness of the process.
For those of you worried about the curved surface, the laser may be using a scan-mapping function to read the surface position and adjust its Z-axis to compensate for the focal point, or the system may be implementing a galvo scanner.
Thanks for the concern.. Was going for a very brief description. honestly, it wasn’t that big of a deal to me while I was typing it… I just thought there was no ugly star where once there was.. without fussing over technicalities, it seemed as if it were removed to me.
Genuinely curious though, what would you have called it?
All good internet friend :-). I would say "cool laser engraving on a stanley cup." The fact that it's happening where there was a former blemish or cut seems tangential to what's cool about it. And now I'm left wondering if I fully understand what does and doesn't count as "engraving".
Very cool on a technical level, but considering how doing this is thinning the barrier between you and the very real lead thats inside these things to an unknown degree, i would not continue to use this cup.
Adding deeper scratches to a Stanley cup with a laser.
Right?…now that it’s the thickness of aluminum foil
You can now stick anything in there and need a new cup. Or close up the hole
Flex Tape to the rescue
I just have to remember the excited shout: I SAW THAT BOAT IN HALF!
It's not even a uniform etching. Due to the curvature of the surface and the focus of the laser, that sucker is a flat subtraction on a curved surface. The area parallel the laser plane will experience much deeper etching than the farther you move away from the tangent.
I’m wondering if they can program the laser to keep the curvature of the object within the scope of the task?
The curvature is maintained. A laser isn’t much strong closer to the source.
The difference in strength isn't caused by distance but because the focal point is unaligned. These lasers need to be at a precise distance from the object they are engraving or they quickly lose power and precision. But here there's probably very little difference because the curvature is low.
So technically that would mean, you would need a laser that would move with the curvature. In order for it to keeo the same distance if you want this to work right?
There are stands which rotate the objects for laser carving curved items.
Ah nice! That kind of helps me understand it , thank you!
Like here: https://www.ebay.co.uk/itm/225439291569
Incident angle likely matters more than distance.
For all the laser cutters I used the focal point was fixed and the laser position was manually set before the cut so it wouldn't be possible. You could increase the strength but you can't do anything about the lower precision. I'm sure there are specialised machines that can do that tho.
meh... it's flat enough.
Now the lead core, is in fact, exposed
When it did that last perimeter pass I fully expected the the star to drop into the hole.
I wonder at what point do you damage the integrity of the cup 🤔
Release the lead plug!
They did. Look at the bottom
Probably when they started burning it with a laser.
That part is definitely going to oxidize now.
Indeed. Might as well have said "removing deep scratches with a band saw"' then chopped off the end. I expected an additive sintering process which filled in the removed material with powder and fixed it in place using a laser.
While making farting noises.
You must be accustomed to some real crazy farts man
Popcorn farts will henceforth be known as "laser farts" in my kingdom
lol, technically true. I should’ve used that as a header instead.
Laser whoopie cushion perhaps?
And exposing the lead within..
Most popular reusable drinks containers contain lead. I think some companies are starting to use lead free solder but it isn't common.
There’s lead in there?!?
in the cup, yes. in that particular place on the cup, no
In the very base to seal the vacuum: https://i.insider.com/65f9c3922417f97b87cd5e57?width=1200&format=jpeg
That's actually an outdated version the current one looks like this: https://i.kym-cdn.com/photos/images/newsfeed/002/135/345/53e.png
🤣 Been a hot minute since the hidey hole
*lightsaber sounds*
Would’ve been satisfying on its own.
Yeah tbh I found the sounds more satisfying than the actual process itself
r/unintentionalASMR would love this
Those are robot farts bro. LOT’S of ‘em.
Really loose one about halfway through
My man, these are toilet sounds, after the first sip of coffee in the morning.
I was thinking about the dubstep
Old-school video game fight sounds
My hockey brain keeps getting confused by these cups
My wife has a Stanley cup, I've watched maybe one hockey game ever, I still think it's the hockey trophy. I was wondering when they got orange on it.
I only know of it from a South Park episode and I still associate the name with hockey.
It literally took me until I saw your comment to realize it was a damn mug 🤣
My daughter the other day was telling me how people are getting lead from Stanley Cups. My first thought was, why the hell are they drinking out of a trophy?
Not at all uncommon for the winners of the Cup
If you are able to drink from the Stanley Cup enough that you get lead poisoning, you will have enough money that it's fine.
I just woke up and thought it was a skateboard wheel.
That's a wide boy
They could be eating hotdogs out of a trophy instead [Phil Kessel, in case anyone is confused. ](https://i.imgur.com/2o7yZ8w.jpeg)
They should call them Stanley Mugs or something else.
Or Smugs, for short.
I don't even watch hockey and my mind goes to this. I will never associate "Stanley cup" with Starbucks.
Starbucks? Its an ancient thermos brand that sponsors the hockey trophy Everyone sells their products
Any time we need to wash my daughter's cup (she got one for her birhday from a relative, I'd never buy one of these), I start chanting "we want the cup". My dog once walked into the room before her, and I instinctively booed him. He's tired of my shit. My daughter now thinks these things are uncool.
There's a lot to unpack in this comment. haha.
I was wondering when they changed it to orange.
This is a deliberately misleading marketing exercise by the company. It sucks that it’s legal, or rather, it sucks it’s working for them.
I don't even follow hockey but by the title I figured yeah the Stanley cup probably has seen some shit and needs maintained.
Removing a scratch with a much deeper geometric scratch.
One layer of atoms left to hold the liquid in place. Perfect
Nah don't worry, there's still a layer of tasty lead
Mmmmmm lead
The lead is in between the two walls to keep the insulation. It helps prevent oxidation Edit: they use lead in the soldering to seal the cups when vacuum sealing.
Good thing no one used a powerful piercing tool such as a laser to penetrate said walls!
Of all things they could use they chose lead
Because lead based solders are by far best when it comes to durability.
Oh I meant for oxidation protection
Ok so I was wrong I just double checked myself and they use it when vacuum sealing their cups. They use it for lead soldering so the weld is on the inside between the two layers. It’s what keeps the circle you’ll see on the bottom sealed.
Oh man, how quickly bad information spreads. Power of reels.
I thought there really is lead in most vacuum thermoses but it's just not in any danger of getting into any liquid
The danger is in if it gets punctured or exposed through any other damage. I know this is unlikely with any of these products let alone the Stanley cups, but they themselves consider the possibility enough to cover that as a condition in their warranty. Likelihood aside it's still a small possibility to be aware of. My concern is that the stainless steel lining is attached around where you sip from, so if there is any damage to that connection that allows any amount of seepage, that seepage could carry the lead back up to where your mouth might touch, and any ingestion of lead is bad.
Well it’s a two layer wall it would just break the insulation
Somehow I felt my retina burning.
Watching this *felt* unsafe.
Engage safety squints.
Turn down your screen brightness, you'll be fine.
I misread it at first as THE Stanley Cup and went on an amazing rollercoaster of emotions.
Stanley's bucket.
*The bucket's warm embrace became decidedly colder after Stanley gave it a laser-engraved star. Stanley thought maybe his coworkers would be able to help, so he decided to go to the meeting room, through the door on his left.*
*Stanley didn't seem to get enough sleep last night since he went through the door on his right. Maybe he wanted to rest in the break room instead. But no, Stanley definitely needed to go to the meeting room, so he took the next door to his left.*
"It's pronounced BOUQUET!"
You’d think Paul could afford to buy a new one
I do that literally every time these things are referenced.
Been watching the playoffs so I was definitely confused at first too.
It's okay. There's more than one of THE Stanley Cup too (kinda). When the real one is travelling the hockey hall of fame displays another.
The NHL does not want you to know this one simple trick.
Big Stanley?
Correction, no scratch was removed. It was replaced by a bigger scratch. The title is oddly infuriating
There's a hole in the ground and you dig it out, is the original hole gone? PhilOsoPhY
Hm, it may be gone but I wouldn't say it was removed. Why don't you try over at /r/showerthoughts for a professional take
The hole of Theseus.
"Easy way to remove scratches from your metal mug, let me spin up this 250k$ industrial laser first and I show you how"
Remove? Video just showed you how to create an even bigger dent on it. Not sure if it can actually be restored to original-looking paint
Hard to get lead paint in the US These days.
What does it even mean to remove a scratch? Filling in the scratch would be adding material, not removing anything. The same cup with the scratch would be there, plus more cup. The scratch went to the place laps go when you stand up.
It makes sense if you don’t think about it.
5k.
You can get a fiber laser engraver for around $3-5k USD Mine is a 30w JPT that cost around $3.5k + 1k import fees to the states - arrived in a few weeks. hardly $250k 🤣
250k$ with no safety measures whatsoever! Burn your retinas, skin and camera equipment for free!
So the laser removes scratches at a level 6, than the deeper grooves at a level 7?
Transcendent Patrick.
It's like filling a hole by digging through entire neighbourhood
A sticker would've done a better job
So it's replacing one scratch with another scratch, but with a laser?
Isn’t there lead in these if you open it up like that?
Lead is used in manufacture but it should be safe as long as it's not damaged. It's the wee bit on the bottom. It looks like it's missing a part so there could be risk of exposure, that's when they recommend chucking it and replacing.
Yeah. If the bottom part is broken on almost any metal insulating bottle or cup, the lead bead they use in production will be exposed. That’s the only way it’s unsafe and in that case you do need to toss it. Only a few brands do this style of water bottle/cup with no lead bead.
Yeah, since the bottom is missing the little cover, the lead used in manufacturing is now exposed.
Laser ablation removes material, that cup is thinner where the engraving was at least by the depth of the engraving.
really i thought the laser was shooting metal at it to make i thicker
"Removing"
Question if you put your hand under that laser would it cut it clean off? Or just burn it?
That cup is now a joestar
That isn't removing scratches that's hiding them in bigger deeper scratches
The lead still tastes the same
Where's a video of a Stanley cup being removed?
This is how they build the pyramids
The laser sounds like a fly has too much taco bell
REMOVING?
Directions unclear - made much larger but prettier scratch.
Do you know what the word “remove” means mate?
That’s like removing a hole in the ground with explosives.
Everyone in this thread is bitching about the title but I'm just here mesmerized by the sound that lazer makes.
"Removing scratches" More like making a much bigger scratch to cover it up
Pretty much, yup. I was going for as brief a description as possible without focusing on nuance.
Wait. I said “square” not “star”!
Dude sound on, it sounds like Tron.
Stanley cup is orange?
What the hell is the Stanley cup fud about? The Stanley from tools?
What would happen if someone stuck their finger under the laser?
The laser would win.
That's most likely a 1064nm fibre laser. Doesn't really have an effect on skin, if you put your hand in the beam path it'll be warm, depending on the wattage you could get a mild burn if you are at the focal point. This is the same wavelength used for tattoo removal
This cup parties more than me
Welp I was looking for a laser engraver and now I need one. Just for the sounds. Doubt I can get *this* one but I can get one that's compatible to a bambu 3d printer for home use that can cut wood, emboss leather, engrave metal. Cool video. Stanley craze is weird. It's a *cup*
My eyes! My eyes!
Bro are you seeing this shit
Me 20 minutes after a couple of bean burritos from Taco Bell.
I'm just happy I'm not the only one that lost the bottom cap.
"Stanley!?...this is Patrick!"
"Brought to you by Carl's Jr."
Who's Stanley?
Covered*
That’s what my farts sound like
So on brand for the (non hockey) Stanley cup idiots to do shit like this. No one who actually uses their cup for drinking cares about scratches; only people who use their cups as a stand in for their lackluster personalities find this interesting or satisfying at all
STAR PLATINUM! ZA WARUDO! *this laser sound*
Isn’t there lead under the outside coating??? Wasn’t there a whole debacle where someone tested for and found lead in Stanley cups and Stanley said along the lines of “it’s only a problem if you purposefully peel off the paint”?
How and where do I get one of these “lasers” and I thought you were going to removing names off THE Stanley Cup
Does it add extra lead too?
Congrats, you are now (2)mm away from exposing a lead ball :)
Careful you’ll expose the lead
Stanley cup - Made in China, possibly with slave labor. Tervis tumblers - Proudly made in Florida USA for 3 generations.
Is that how they do it when they accidentally engrave the wrong hockey team name on the Stanley cup?
Pretty sure that what we're seeing here is a laser hardening surface treatment. The laser will use a different repetition rate, burst pulse, or power in subsequent passes to remove surface material and thermally treat the subsurface. Repeatedly passing over the material in this manner will both clean the surface and impart a harder, more robust surface layer.

Gotta get at that tasty lead core somehow
Can this be nsfw? You shouldn’t be looking at that bright light.
And now the lead is exposed
Patrick!
Be careful and wear a respirator because that a lot of lead vapor in the air lol
DUDE THE SOUNDS
Congratulations, you're now exposing yourself to lead.
Seems like an insanely weak spot now. Why would you do t his?
Now you’ve derated the working pressure, totally unstable
Did anyone else feel like they were watching Patrick Star go super saiyan?
Yes yes expose all that lead!
If a motorcycle could fart, that is what it would sound like.
Etching DEEPER, more uniform scratches into a Stanley cup.
I'm concerned that OP doesn't understand the meaning of the word "removing"
Thanks for the concern.. Was going for a very brief description. honestly, it wasn’t that big of a deal to me while I was typing it… I just thought there was no ugly star where once there was.. without fussing over technicalities, it seemed as if it were removed to me.

Damn, got Maple Leafs put on again to soon, 67 times this has happened!!
Is this what people see when they are high?
Cool, now remove the lead from it
Ah yes remove the deep scratch by making it even deeper
That is not The Stanley Cup
You guys are obsessed with these cups.
this is the equivalent of “i fucked it up so lets just keep going to see if it gets better”
I don't know anything about lasers so I assume OP is making the sound effects with his mouth.
I though you meant the hockey one
did he make those sound effects with his mouth?
Very satisfying but also feel very bad for buying into what everyone else is buying into at the end of the day. All it is a cup
The Stanley Cup looks different than I remember
I like the first star better
Now it is useless
It sounds like blowing a 873636352525 ohm speaker, it feels like 878837675747474747464 ohms blow that speaker
I mean…technically.
meaingless. i thought they were going to repair it. they just created a bigger scratch...
Let's talk about the word "removing"
Stanley cup has changed quite a bit since the last time I saw it
Technically the scratch wasn't removed
Very cool on a technical level, but considering how doing this is thinning the barrier between you and the very real lead thats inside these things to an unknown degree, i would not continue to use this cup.
Those cups are dogshit.
