DIY 1000W Fiber Laser Cutter Part 1: Project Introduction

If you want to build your own fiber laser cutter, join our Patreon group: / diyfiberlaser
UPDATE MAY 2024: I have an updated, better, and cheaper design... also check out this video series: • DIY Fiber Laser Cutter... *
I've been working on building this DIY 1000W fiber laser cutter for the past 6 months and I've finally reached the stage where I've begun successfully making test cuts with the machine. Because I could not find any guides on the internet to help me with the build, I am going to create a series of videos sharing what I've learned during the process. Please understand that I am a novice on the subject, and that fiber lasers can be very dangerous, if you are going to build or use a laser, please do your own research and understand the safety risks!

* UPDATE MAY 2024: I have an updated, better, and cheaper design...also check out this video series: kzbin.info/www/bejne/d32QoqCBj92mgpY * I'm getting a lot of comments about the gas prices and I really appreciate everyones feedback. I should have gone into a little more detail in the video...the prices I listed are to fill 300 cu/ft bottles at Airgas. I purchased their Ultra High Purity rated gasses, because it was the only option that they offered that met the requirements recommended by RayTools (the laser head manufacturer) of 99.95% purity,

[@patrickd9551]

Yeah, that high purity stuff is hella expensive. But if compressed air is an option, then "low purity" compressed gasses are surely an option. Compared to just air, those cheap gases are already as pure as you can get them. Also looking forward to seeing the buildseries and breakdown. Subbed.

[@DimensionMachine]

If you are cutting a bunch also consider a liquidpack nitrogen bottle. prob going to cost over a grand to get one there, but then the cost of the actual gas it produces will be way way cheaper in the long run. And as others have said the 30 or less per bottle nitrogen is what most people use from what I have seen. Very impressive build!

[@tullgutten]

Can you use Argon instead? It is a cheap welding gas. Think we get about the same size bottle here with a refill price about 150-250 usd.

[@StuffMadeHere]

Never seen anyone build one of these before. The results look awesome. One thing to consider if you need more power and you’re not planning to run it 24/7 is a gas generator. For a couple grand you should be able to find a high enough power inverter generator that can run anything you need. Another option specifically regarding the air compressor is a gas powered compressor that you fire up when you’re going to cut. You can get really high CFM ones, especially if go up to a diesel unit. The essential craftsman does this for his air hammer which is super air hungry.

[@kevinm413]

I can't be the only one a little excited that Shane is now thinking about fiber lasers..

[@diyfiberlaser]

Thank you Sir! I never thought about a gas generator, but I have been keeping an eye on Marketplace for a used gas powered compressor…I just picked up a used air dryer tonight. BTW, I’m a little star-struck…I have to publicly admit that you are my KZbin hero!!! 😃

[@ericapelz260]

@@diyfiberlaser I work with big air compressors for scientific work as part of my job. Keep in mind that the CFM of a compressor decreases as pressure increases. Be cautious of large piston compressors, that's a lot of mass moving, and they tend to have vibration problems, especially the oilless ones (I have a $20K compressor offline atm because it's trying to rip itself apart). Scroll compressors are quiet and good to 120 psi or so. Compressors with threaded inlets can be used in series, so one kicks you to 100 PSI, the next bumps you up to 200, etc. The size of the tank only affects the time between compressor runs. Old tanks that have sat with water in the bottom can rupture and kill people, so be cautious of used tanks (also drain your tank daily!). Even a modestly sized tank rupturing at 200 PSI will take the walls out of that building. Some years ago, I was running a small tabletop sand blaster in my garage. To get the pressure and volume of air I needed, I ran three small 120-volt compressors in parallel. The setup was vastly cheaper than a single large compressor; you can save space by plumbing multiple pumps into a single tank. Also, there are places that sell used scientific equipment; you could look for a used nitrogen generator. IMHO gas fueled air compressors are a massive PITA. you have far more maintenance, they tend to be loud, and you have the concern of the exhaust being drawn into the intake and brought into your shop with a whole lot of moisture. You can easily overload a dryer.

[@longshot726]

@@diyfiberlaser Look at something like a Motor Guard filter to go along with the air drier. The air drier will remove moisture but won't help much with removing contaminants and used gas compressors aren't treated very nice during their life. Also, look for a stationary gas air compressor instead of a wheel barrow style since they will provide more CFM due to having larger pumps.

[@andy123law]

Not sure if you can get a big enough gas generator (Nitrogen) that would be able to keep up with the power available in a home shop. I have a nitrogen generator system and it costs about the same as the laser. It has not 1 but 2 compressors! A standard 11kw 3 phase 10bar atlas copco air compressor and a high pressure 200bar booster compressor to fill 4x 50l 200bar cylinders. I can out run this system when cutting 2mm stainless steel. The 1kw fibre laser and nitrogen system probably pull 30kw 400v 3 phase at full power. I would try to find a cheaper source of bottled nitrogen or try a high pressure dive compressor and fill several cylinders when the laser is off and cut on air. Adjust your laser parameters to fine tune the results 👍

For the record, Eagle Pair goggles, and specifically those you have, are completely unsafe and don't provide any significant protection at 1064nm. Me and a few colleagues tested this on industrial spectrophotometers designed for this purpose(testing coatings/film transmission), and they transmit as much as 8% of light where they should be transmitting 0.0000001% Get a pair for 800-1100nm @ OD6 or higher, from any of the following brands: Kentek, Lasertack, Thorlabs, Honeywell, Glendale, Sperian, Newport/MKS, Edmund Optics, Laservision/Uvex, Laserglow, NoIR (LaserShield). As others pointed out, you are being straight up *gouged* for gas price. You don't need UHP, refilling a 40L nitrogen bottle costs me $15, oxygen $45. Both at regular technical purity, 99.95%. Even 95% reject garbage grade will work perfectly fine for cutting. Also, when opening the gas cylinder, you want to open the valve at least halfway, otherwise you'll be wearing the gasket through way more quickly and can cause leaks(high pressure leaks are scary). If you have space and power, you could also try replacing the oxygen supply with a small army of oxygen concentrators. They're basically free in the US after they become no longer fit for medical uses, and I reckon you could get away with around 4-6 units running in parallel, through a tiny air compressor on their output to bring up the pressure. They'll also provide nitrogen(well, oxygen-free air) out the reject port.

[@diyfiberlaser]

Thanks for sharing your wealth of knowledge! The glasses I have are FreeMascot (maybe it's rebrand? amzn.to/3GVoWEE) they say they're OD8 800nm-1100nm, but I will check out some of the other brands you listed. And thanks, I will get cheaper gas next time

Hey Travis, Hi from Australia!! And all I can say is wow!! this is the definition of what "not being a sheep in the crowd" means. All the "critics" are quite happy to offer their opinions, keyboard warriors, where as your desire to move forward and do, well done mate!. Motion control has been there for decades, the mechanics and designs are a plenty - there are people out there who have made these DIY Fibre machines, they're just not confident enough, or care to put them up for the world to see and criticise. Budgets are the key ingredient to any project, and design choices based on available tech, or budget constraints. At the end, the only difference between a DIY and commercial machine, is support, and if you are the builder, you are the supporter, you don't have the overhead of having a technician on hand to take care of warranty. There are those who will argue that the quality of the machine... stop, quality is in the end result of the purpose of the tool. The logo that Travis just cut is beautiful and a high "quality" (costly) machine would do no better. Looking forward to the rest of your video series Travis, just subscribed.

You are the first person to build a Faber laser on KZbin congrats my friend And the precision of this machine is just amazing

[@heyallenify]

Thanks for sharing this project! About the gasses, I don't know where you're getting your bottles filled, but I'd suggest calling around the welding supply houses, as neither of those gasses are particularly exotic, and are commonly available for various processes. Nitrogen is ~78% of the atmosphere, and not in any way in short supply. Oxygen is ~20% of the atmosphere, and again not a short supply issue. I usually use a nearby welding gas supply house for argon, argon/CO2, oxygen, acetylene, and nitrogen. My biggest cost savings on this was just checking around the stores and comparing prices. AirGas was always been one of the most expensive, as well as prone to trying to force bottle rental instead of purchased bottles.

[@JulianMakes]

Hi travis I’m watching this for the second time, and I’m realising your gas prices are way too high. Those prices sound like the cost to buy the bottles. If you rent them they are 100-200 per big bottle. Just to reiterate I think this project is so amazing. Bravo

[@ChrisS-oo6fl]

Like You, I have also have spent a few years regularly searching the internet for an example of this!!!!!! Please do a good job documenting this! Including links to the fiber components. Thank you for these videos!

[@ChrisS-oo6fl]

Focus on showing the assembly or a detailed trace/expo of the laser components. This is what makes your build unique and important to those of us who’ve wanted to attempt this build for awhile. The gantry and table build aren’t a big deal there’s easily a million tutorials that can be found by on KZbin alone posted almost weekly and plenty more on properly building a controller. Why did you chose to go with a “laser” controller? Couldn’t you just use Mach 3/4 or LinuxCNC with a traditional motion control card setup? Was there customs fees and did you need a broker for any of the laser components?

I ended up buying a 1.5kW RECI laser source for this, but gave up when I found that you can buy a complete machine (at least right now, prices have dropped a lot) for about your budget plus shipping/duties. The laser source is now in a 3 in 1 handheld Weld/Cut/Clean system. Maybe build a laser welder next?

[@jamesmead1974]

I'm so pumped to find this video! I'm collecting parts to build a DIY fiber laser too, but there's so many missing elements of the system. I'm mostly interested in the controller. I've got a 4kw IPG sitting in my garage. It's relatively easy to generate 3 phase power with "off grid solar inverters" but it's not the cheapest option. You can do ~15kw for around $2000 or so. I'm so into you

[@diyfiberlaser]

From my research, it appears most commercial machines are using Friendess controllers and CypCut software. I went with the Ruida RD6563F controller because it is cheaper and I'm familiar using a Ruida controller on my C02 lase. It has it's own software called RDCutist V2.0. It seems less robust than the CypCut software, but so far, has all of the basic features I've needed.

[@pupdoggify]

Hi Travis, I took the same route as you did in 2013 with a CO2 laser, when fiber lasers were a new technology. Raycus and Max laser weren't around yet. One thing that could benefit you greatly, and I would love to collaborate with you if needed, is to create your own Nitrogen generator. This will eliminate the cost of purchasing or refilling N2 every time you cut exotic metals such as aluminum, stainless steel, copper, brass, etc. For steel, you can actually use dry compressed air instead of oxygen. However, this must be supplied by a reputable rotary screw compressor (5-10HP or more) which is the bulk of the cost upfront.

Great Project! I pay about $35 for oxygen tank exchange (for a tank about half your size) - at work where we buy a lot of gas I pay about $50 for a nitrogen tank exchange. Buying the first tank is expensive but after that it is just a matter of exchanging tanks at the local welding supply store. I don't know how much gas you need but I purchase used oxygen concentrators (off Craigslist or the marketplace) for torches for glasswork (you can compress the oxygen for storage if needed). for a 5 LPM unit I pay $50 to $200 - You should be able to get the nitrogen out of the exhaust without too much trouble. If the concentrator breaks there is a great little low pressure compressor inside that is worth whatever you paid.

I have 22+ years working on industrial lasers, if you are going to use compressed air, 3 important words, filtration, filtration, filtration. Any water vapor that contaminates your lens or collimator and you will be replacing them excessively, if you can’t get them clean enough. Fiber lasers require a pristine lens to function properly.

I have worked with Co2 lasers cutting metals, watch for micro metal particles in your extraction system. I have converted an old EverFlo Oxygen Concentrator to produce ondemand O2 for a small torch setup, not the purest O2 but works well enough for gas welding. Just food for thought.

Dam, that's awesome! Just subscribed, I really wan to watch this build.

[@davedavidson4215]

Very impressive!! Nice to see you were not affraid to run DIY project with such expensive components. Can I ask why ballscrew instead of a belt?

[@centurialinc]

Awesome! Do some test cuts showing the types of materials you can cut and the max thickness please and thank you. I want to cut steel plates up to half inch. I’m curious if you could do that with oxygen

[@ackbar8297]

You have some really awesome work into this. Keep it going, subscribed!

[@leighharvey9150]

Could add a larger tank to get the air you need. Still won’t run indefinitely but if you let the air compressor build up Pressure first it will extend your cutting time on compressed air.

Very interesting, I am looking at making (because nobody makes one) a combo unit, CNC router and laser. I have been thinking of getting a MillRight and making the table move and not the gantry, mount the laser on the back of the mill head off of the table. and have a small footprint that does two functions. The application is cut 1" boards, 5/8 aluminum, and laser thin gauge metal, with engraving.

Fantastic! Thanks for sharing!! $15,000 is still too much for most of us. I hope I get to see fiber lasers be cheap and handled like plasma cutters are today. I remember as a kid seeing and using the first very large plasma cutter and it was mind blowing. Now they have units so small and cheap it's crazy.

Super cool build!!! I can't wait to watch more

[@spehropefhany]

Very workmanlike job. T. The stepper drivers (closed loop servo?) look nice, not cheap at all. Looking forward to more fiber (lasers) in my KZbin diet.

[@joachimsingh2929]

If you get the plumbing you could install your own filling station to fill your own bottles of compressed air. Diving bottles at 200 bar are pretty cheap.

[@MethiasZa]

Man this is awesome. I’ve been working on building a mere CO2 laser (possibly 130w version, after that the prices go up fast) as a fiver is way out of my budget but this is just inspiring

[@Nynexx]

best laser cutter you can buy. Fiber is wicked.

[@Eric-bh6ie]

Wow just wow!! Amazing work

[@electroayman]

This is a great video and I am looking forward to seeing what follows. Good pacing/information here.

[@PeteBrubaker]

Welp, I no longer want to build a CNC plasma cutter. Thanks Travis!

[@lezbriddon]

wow the little cut at the end, not much makes me amazed but wow thats accurate fine cutting. now I'm going into the spare room to stare at my ebay k40........

[@karoma7898]

4:42 , that's a very common cost cutting measure, I work with a 2500W laser at work (industrial), we do up to 10mm black steel or 6mm stainless steel, reliably, BUT, we have a liquid ring compressor system, and HIGH pressure is an important factor in evacuating molten metal and a good finish. I'd be happy to relay any questions you have to our more experienced operator, keep in mind, I live in the middle east, so specific pricing question may be irrelevant.

[@juanwiedemann152]

I haven’t watched your video yet, but you’re a god

[@simonstergaard]

WOW, what a beast! Lol'ed so hard at the cat/dog flap exhaust port. Keep it up !

[@65_roses_jku7]

Ok, I’m not going to say it’s the best option but I operated at 1500 watt fiber laser for 4 years on straight compressed air. Was it recommended by the manufacturer? certainly not but it did work. Our big, expensive laser got a weekly nitrogen and Co2 refill, though.
