Laser Cutting Stainless Steel Living Hinge Patterns

[@B30pt87]

So neat! I love it that you posted a link to the patterns- some people are set on money & won't divulge anything for fear of losing a sale, others are more generous with their knowledge. It never seems to dawn on the tightfisted ones that generosity pays off at least as well. P.S. thanks for the tip about the shop gloves

[@ProtoG42]

Thank you, I really appreciate positive comments like this!

[@billherreid9661]

Adolf's Law: if you draw any repeating pattern using right angles, sooner or later you'll end up with swastikas.

[@B30pt87]

That was an excellent demonstration! Thanks for posting it.

[@ProtoG42]

It's not the best way of making hand formable parts, but it looks pretty and is more of an artistic approach. Do a quick image search of living hinges and you'll see example of practical application. Also, the yield limit is not the same as the solid sheet. The material yield is the same, but I can bend the "bracket" pattern about 90 degrees and it still returns to flat. The solid sheet yields pretty quickly at about 10 degrees. Someone with an idea could design something they could hand form themselves without proper sheetmetal tools and save a lot of money on shipping because it ships flat.

[@notyou1567]

You could make and sell custom electric guitar pickguards. How much did the machine cost?

[@pacocarmona7697]

Hey im interested in more information for a diy project i have a design and want to see if you can help

[@burtosis]

I think if I ever got to own one of these machines I'd cry out of happiness.

[@miamimovies]

Are there any hexagon-pattern living hinges? I would think that would be a better shape for 3D flexing than something based off of squares or triangles. edit: never mind, I am a dummy, the triangle pattern is also a hexagon

[@LaughingVegetables]

Learn something new everyday. Cheers!

[@yonasrahendanu854]

Hi, could you tell me where did you get the clamp?

[@JeremyCook]

Pretty neat. Had not heard the term "living hinges." Guess that's the same as kerf cutting?

[@nebnoswel]

In this case yah, exact same concept, but "living hinge" is used any time a hinge is made of one solid piece. Think like a dvd case where the hinge is the same piece of plastic as the front and back.

[@JeremyCook]

Ah, neat, thanks. So the CD case is a living hinge, as it's built into the plastic, even though the case is two pieces?

[@nathandean1687]

the solid black cases would be living hinge. where as the clear hinges are not.

[@kkfoto]

First time I heard it too. Something like a ketchup bottle cap? :)

[@AeleosGFX]

damn that laser cutter is fast

[@ProtoG42]

It beats a bandsaw, that’s for sure! It's cutting the 0.062" stainless steel in the beginning of the video at about 700 ipm and the other patterns at 1100 ipm!

[@nerfinator03]

Von Skipppy proving yet the saying you are not intelligent. Surely you are in the pay to enter mensa club..

[@gamerpaddy]

do fiber laser cutters have any "high" running costs, like waterjet or co2 lasers?

[@CNCGuy]

On the contrary they are very cheap to run as compared to a similar co2 laser. A new 2 kw fiberlaser can outperform a 4kw co2. I've seen a 2kw cut through 1 inch steel at 25ipm.

[@gregkeshishian3485]

Does any one know where to get those spring loaded clamps which help prevent the small sheets from shifting on the table? We have a fiber laser and struggle with small pieces shifting during the cutting. I have googled around but cannot find them

[@thegeneralissimo470]

How often do you have to replace the supporting grating?

[@barracudatubeman]

Nite, do you have any system on your fiber laser to avoid any issue with stainless reflection? Thanks,

[@mrechbreger]

How accurate can you cut with this laser cutter? what is the cutting diameter? Can this one cut small gears eg. m0.5 or m0.3?

[@maxpayne438]

What lantek version do you use?

[@ProtoG42]

It's the latest version but combined with LVD's software called CADMAN. I also use it to program the turret punch.

[@richardraymond5535]

Is the cutting part sped up or is that how quick it cuts the stainless?

[@Xanthopteryx]

How log does that support base grid last?

[@ProtoG42]

I'm not sure, it has lasted 6 months so far. The machine cuts new slats for itself but we scrub them with a wire brush on an angle grinder.

[@RandomGuy0987]

That laser cutter is cool. Faster than I expected.

[@brissomburdiles595]

como se llama ese sistema de sujecion para la plancha

[@lobitojavi]

where do i can find thise clamps?? thanks

[@rubeusmagnus7634]

Wow! I'm really impressed, that laser machine works so well on stainless steel. My question is: Aside from those pattern you've demonstrated, will your application work on 2-3 inches diameter of round stainless plates (2.5-3mm thick) to turn it on a 2d medallions? Is it easy for you to centralize a given pattern? I am asking you because you may be the right person to contact about my projects and I might need your professional help one day. Thanks in advance.

[@Monkeyz60593]

Where can I find that first cutting plan? For the spiral/feather thing ? 😁

[@jacktumbleweed]

Fabric pattern is real pleasing to my eyes. All look cool though!

[@mikezhang7646]

good laser cutting work

[@powertomato]

Wow this was fun to watch. I wasn't sure if the footage was sped up. The laser cutters I've seen so far couldn't cut wood at that speed. How powerful is that laser? With all that molten/burning metal flying around, how does the lens stay clean?

[@ProtoG42]

The laser is 2000 Watts. There is a 3000L liquid nitrogen tank seen at the end of the video that purges the cut and forcefully ejects the molten metal downward.

[@av6966]

Good Video! I liked how you show the cooling system for the LAYZER at the end and the 3d square pattern looked hella nice!!! Subbed hoped to see more laser cutting in my feed! Peace!

[@iian_]

cool. how much heat does this transfer to the metal? Its obviously safe to touch but is it warm?

[@ProtoG42]

Thanks, it's slightly warm. High pressure nitrogen is ejecting molten metal out the back of the metal before the heat really has a chance to spread.

[@lobitojavi]

hello mister, i dont have to much money to get this kind of machines, but do you have good references of machines around 500W fiber laser brands?? of course smaller, thanks

[@magnuswootton6181]

I wonder if u could use these for robot actuators.

[@wernertooldievogt730]

how long would it take to use a bottle of nitrogen cutting SS, i am looking at buying a machine and am curious to the consumption per hour and how much i will need to have holding wise.

[@chanxanlaserequipment4006]

[@MECHTheo]

I'm wondering where you got those little clamp/weights? I'm running into the problem with my smaller pieces of light gauge steel wanting to fly away.

[@chriskirkham9661]

They are called Cleco fasteners. There are clamping ones as shown in the video, and they also make them for holding sheet metal together through rivet holes. They are very common in the aerospace and automotive world!

[@ninocaselli6290]

2:39 the laser cutter starts to play LEDZEPLINS lmigrant song

[@JoeHeiserA]

What is the width of the material removed / the diameter of the beam at its focal point? Seems tiny

[@digitaluddite]

What are the clamps holding down the plate? Those look like they might be handy in the waterjet as well!

[@ProtoG42]

Those are Cleco side clamps: amzn.to/2Bc2DZN

[@afj9966]

is that some kind of water dropping in order to cool down the nozzel? silly me, didn't see any water droplet when you take it up so it's just some sparkles?

[@ProtoG42]

No water. It using liquid nitrogen to purge the cut, but it is already gas by the time it reaches the nozzle.

[@JGnLAU8OAWF6]

Why not regular air? Can this laser cutter use oxygen for cutting thicker material?

[@ProtoG42]

Regular air will oxidize metal and result in discoloration of the areas surrounding the cut. Yes, we use oxygen to cut thick steel but the edges are very dark and need to be cleaned up.

[@simonburklin1189]

whats the thickness of the material hes using?

[@ProtoG42]

That is 16ga stainless steel which is about 0.059”

[@martinmiglio]

What’s the point of the z axis travel on a laser cutter

[@ProtoG42]

Several reasons. Parts can tip up and hit the nozzle. We can also cut enclosures and parts that are already formed so it cuts more than just sheet metal. There are two beds, a top and lower bed so the z axis has around a 15" reach. Another reason is to prevent warping. If a part has a lot of features too close together, it's better to raise the head to allow the heat to spread more evenly.

[@kobisjeruk]

I notice the laser cutter went with the longest route (as evident during the 3rd piece cutting process) as the most efficient use of the 'on' time. Never seen this process before, so this might be a silly question but doesn't it produce intense heat (since you seem to be able to handle the finished work with your bare hands)?

[@ProtoG42]

Stainless steel has a very poor thermal conductivity so it isn't very good at spreading heat. The laser beam is about 0.006"(0.1524mm) and the cut is being purged with high pressure nitrogen gas. It's barely warm after it's done. Thicker parts and aluminum parts do get quite a bit hotter though.

[@godfreypoon5148]

+Von Skipppy He won't post nudes... just saving you from asking.

[@vonskipppy1152]

Not trying to be snarky - I just don't see the usefulness of those patterns as "living hinges" - seems like a lot of equipment, and a lot of time to get very little in results - the laser cutter itself is way cool.

[@ProtoG42]

lol, too late for that. Do a quick search for living hinges. Obviously that is not the sole purpose of the machine but living hinges allow for hand formable enclosures, chairs and other parts with spring like features. In addition to functional parts, making parts for sculptures and artistic signage is something we also do.

[@MrBelseBoB]

Some nice videos you got there! What brand is the laser cutter?

[@weaseltown]

Question. I've been looking into getting a laser cutter, and of course a fiber laser seems like the clear choice for cutting metal. However, most of the low-wattage fiber lasers are stationary, and this is clearly on a flatbed, which seems to be more common with cO2 lasers. My question is: is there a particular brand that makes fiber lasers in consumer-level configurations (7-12k price range) that do what's shown here, or am I out of my league?

[@darkshadowsx5949]

the "Clean up" ruined the nice smooth finish... :(

[@ProtoG42]

It looks better than leaving all the piercing marks and sharps edges.

[@SuperAWaC]

it could easily be polished to a mirror finish it would just take time

[@lobitojavi]

what about the droos ??? there are at the back side??

[@stevenclark2188]

I think there's probably changes that could be made to optimize the technique for the material. Steel is already pretty ductile, the ability to transfer and absorb stress is a big part of what makes steel strong. As a result patterns aimed mostly at increasing ductility might not really be as useful as some hypothetical pattern that improves on other properties where steel is weaker.

[@RoDeGuzman]

Great Video. What are those clamps called, and where did you get them? Thanks in advance.

I also like the holders you’re using to hold the thin materials. Keep up the great Laser videos, there aren’t enough how-to’s or tricks of the trade videos for the sheet metal guys!

[@MuradBeybalaev]

Dahell is a "living" hinge?

[@ProtoG42]

"A living hinge is a thin flexible hinge (flexure bearing) made from the same material as the two rigid pieces it connects, rather than cloth, leather, or some other flexible substance." : en.wikipedia.org/wiki/Living_hinge

[@luizbueno5661]

The last pattern you've shown and the 2nd, both give a 3d* result. Their use are not as logical as the other 2. Very nice video. I'm trying to get a fiber laser cnc at the Lab I ran. Crossing fingers.

[@dr.ramondetorres4838]

Do you do custom orders? I used to be a technology teacher, but my labs were taken over by online testing so I teach art. Anyway, I want durable patterns cut that will be used by children to trace designs. I've tried cardboard, tagboard, etc., but it all wears and breaks. Would a stainless steel pattern be more reliable, rugged? I'd love to know where to order many made depending on cost.

[@ProtoG42]

Absolutely, stainless is very durable. Do you have drawings of the patterns?

[@MrWoohoo]

Please cut a Hilbert curve! I don’t think it’d be useful but it would be fascinating to see how it behaved.

[@gremlinlily]

Does the metal not get hot when it gets cut? I'm always scared you'll burn yourself whenever you pick up a part right after the laser is done

[@ProtoG42]

Stainless steel has a very poor thermal conductivity so it isn't very good at spreading heat. The laser beam is about 0.006"(0.1524mm) and the cut is being purged with high pressure nitrogen gas. It's barely warm after it's done. Thicker parts and aluminum parts do get quite a bit hotter.

Hey Proto! how thick of a material can your laser cutter cut? Never seen something cut patterns that fast before! cool vid!

[@JustinAlexanderBell]

Can that laser cut 1/8" or 3mm aluminum?

[@ProtoG42]

Justin Bell It can cut up to about 9mm aluminum. Email me if you need any parts made at [e-mail]

[@lazyh-online4839]

Proto G what kind of pricing would you charge for different parts?

[@ProtoG42]

That depends on several parameters. Lead time, material & thickness, material finish, hardware, post burn operations like deburring, packing shipping, how well the part was drawn, etc.

[@Tischlerimkopf]

Justin Bell newer lasercutters can Cut i think Up to 30mm in Aluminium, and 23mm in staubleisten or Something, I saw 25mm Steel recently, astonishing i can say

[@garthor]

I liked the triangle one, but it looked like some of the angles that it wanted to bend at ran at a diagonal to that section you left at the top giving it too much rigidity... I wonder if that might have something to do with it not being as "functional" as the rest of them... >_>

Underrated comment #0241

[@RobertSzasz]

You might want to try mixing your audio down to mono for the last bit when you were talking. It sounded like you were both intermittently blocking a noise source and perhaps moving from behind the mic to in front of it causing really odd phasing effects.

[@ProtoG42]

That is from me trying to filter out the background noise in my video editor. It's really loud in the shop and it's hard to even hear me without reducing background noise in post. It also distort my voice a bit when I do that but it's better than not being able to hear me. I need a better mic with adjustable gain and filtering.

[@mikeshane2048]

2:39 this machine got good rhythms

[@whatdoiknow1803]

So what about forming it? Creating a "living hinge" and not folding it is like plotting origami lines and not creasing! Check out Ron Resch paper and stick film, Orgamizer by Tomohiro Tachi and Erik Demaine. The possibilities are phenomenal! Keep on exploring and creating brother!

[@minecraftermad]

or maybe a pattern with just a single lazering (no lift ups)

[@dougankrum3328]

...A Thumbs up.......nice work, even if it is just a demonstration....I'm guessing to avoid the issues with cutting stainless this thin, with any 'HOT' source...Plasma, laser....you'd want pretty high current source and fast travels....impressive that the machine can follow the pattern at that speed with no visible distortion in the finished parts..! One of the advantages of Fiber Lasers...very little moving weight... How do the optics stand up to the high number of 'piercings'.....I know that's an issue with Laser, plasma and even Oxy/acet...I've done alloy of oxy/acet and plasma by hand...always tried to do piercings with a 'tilt-in'...and if possible, I'd drill 'pilot' holes....

[@ProtoG42]

With fiber lasers, ther are no mirrors that can be damaged or misaligned like a co2 laser. There is a quartz lens that is purely to protect from debris traveling up the head that is optically clear. It just needs to be cleaned every few weeks with alcohol.

[@GoLightly01100]
