Will a Diode Laser Engrave Steel? | xTool D1 Testing

You can use T1/T2 layer instead of 02 layer so you can frame without really burn the path.

The whole issue of the metal warping here is essentially the same issue when welding or surface grinding thin metal: too much heat concentrated into too small of an area at once. Two suggestions to reduce metal warping. The first is to back the workpiece with a block of a good conductor (such as aluminum) instead of the wood. The other is to change the order of operations so no area is heated for long periods (do a little engraving in an area then move to the opposite end of your work piece) - this may not be practical with the software you use (it would be trivial with MasterCam).

[@KizmitMakesIt]

I've only recently discovered your channel and have been watching a lot of your past videos.

[@paulsim7589]

My top tip for using the 'paint' type spray can, is once you have finished using it flip it upside down and give it a quick press. This will clear the spray head and stops it blocking up.

[@LitchKB]

Metals (overall) tend to be more reflective of light, as the wavelength gets smaller (ie. towards and beyond UV), but inadvertently - it's quite difficult to make lasers very powerful in the small ("Hundreds of nm") wavelengths. But as it happens to be, around the 1,000nm wavelength (Near Infrared) are fibre lasers - which is a technology that basically consists several meters of coiled fibre optic wire, doped in special elements (eg. Ytterbium "Yb"). We then use a primary diode lasers (pump or feed lasers) not unlike your blue ones there, in that they are frequently combined in parallel, but more powerful and typically in the 910nm (+/-) range. These are focused down the doped fibre optic and bounced back between two mirrors, this excites the Ytterbium in the fibre optics, and then that lets go of a slightly longer wavelength (1000-1100nm). The mirror at one end will permit some of the long wavelength light, but still bounce the 900's back and forth. This is fairly efficient in terms of energy saturation, and allows these lasers to be VERY powerful - in the order of dozens of kilowatts, where (with the assistance of compressed oxygen) can cut through inch-thick steel. Fibre lasers are not quite "Hobbyist friendly" yet - the price is still quite high for powerful models (mainly due to the rare element doping requirements and high power optics), but they're coming down. Slowly. Have a look at the OMTech 20W.

[@Clough42]

Marco Reps has a really great fiber laser teardown video. I looked at the fiber laser markers, but they're still a little more than I want to invest. If someone is really itching to send me one...that might be another matter.

And for those who live where the humidity is high, rust can be prevented in one of two ways: 1) periodically wipe down the steel surface and cover it with a thin film of light machine oil or mineral oil; or 2) finely grind or polish the surface to a high sheen. I live where the humidity is 92+ percent during some months. I recently found an old lathe toolholder I made back in the late 1980's in an old toolbox that had been in storage since the early 1990's. I could see a slightly discolored impression of my thumbprint where I'd touched the part decades ago, but the rust beginning to form from the acid in my body oils could not be felt or measured.

[@GregBadabinski]

So after watching the whole video, I have a quick question. What would happen if you tried to engrave "regular" steel? I'd love to be able to laser a makers mark onto my parts, but I typically only use 4140, reaching for other steels as needed (like 303 stainless for things like dumbbell handles). Would it cause excessive oxidation? Or is there another reason you can only use stainless? I should probably just Google this, but other folks may be wondering the same thing so I figured I'd ask here.

[@Metalloys]

Hey, great work. I used to make control panels like these, but I used a different technique : I simply printed on a transparent film, with a high quality inkjet printer, then sandwitched the film between the metal panel and an acrylic (2mm thick) plate with the same openings as in the metal panel and screwed everything together. That tech. gave me 3 advantages : can print in color, and being able to recover/modify and just throw away the old film, and finally the outer acrylic layer is postive protection that can be cleaned easily without worrying about the legends being wiped away. Hope this helps.

[@Clough42]

That's a good process. If you can laser cut the acrylic, even better. :)

[@rpavlik1]

Can also use a vinyl cutter and a temporary or permanent adhesive vinyl. It's like a laser cutter but with an xacto knife instead of a laser...

That's great. I didn't realise that diode lasers could mark stainless directly. I can get a similar result by spraying "Coldgal" zinc based paint onto the bare metal and then running my CO2 laser hot and slow. It's about 5% of the cost of Cermark!

[@campkohler9131]

How do you get rid of the coating from the unmarked area? What other material could one use that is dirt cheap? Flour, powdered sugar, some kind of powdered sand or glass? Maybe a sheet of some kind of colored plastic that can be peeled off after burning. The mind boggles.

James, I use Laserbond 100 which is a lesser expensive alternative to Cermark and does an excellent job. I've used it on metals and glassware and it looks great. Also I've learned that as soon as I get the aerosol can in my hand, muscle memory would take over and I'd be in "paint full-coverage mode"... had to break that habit and learn to only spray the product where there was going to be etching.. as you say, it is expensive so no need to waste on un-etched areas.

I just tried Brilliance Laser Marking Spray for the first time. Washes of with just water, and you can't get any blacker print. I tried the Laser Bond Tech spray which also washes off with water, but only prints in kind of a gray, and leaves residue behind. Last test ran was 20mm @100% which deformed the metal, using Brilliance. Anything higher though will not bond to the metal. And yes, this testing was done with the xTool D-1 laser. Brilliance is expensive, but you don't need to fully cover the part.

[@spudnickuk]

Thank you for sharing, your video shows a diode laser actually burning on stainless and for a hobbyist this is good to know. I have been looking into getting a laser cutter for ages but the cost of getting a Co2 laser is to much for what I intend to use one for, and this type is at good price.

I know that you were just being explicit for demonstration purposes but a quick tip for those that don't know: in Fusion 360 when using the Measure tool you can left-click on any one of the measurements in the Results section to copy that measurement to the clipboard. It can come in handy so you don't have to remember those values when entering them into other fields within Fusion or such as in this case fields in another program such as Illustrator.

I was rather shocked to see that the laser didn't operate, by default, in "plotter mode", but instead opted for a raster method. I've run plotters for decades, and I should have kept the last one that I had, as it would have made a lovely laser engraver.

[@CL-gq3no]

I'm guessing the software is most often used for etching photos, portraits, etc in which case the entire area would need to be covered. Otherwise, that mode makes very little sense as a default.

You can use whatever strategy you prefer. I used two different fill patterns in this project. I do think their primary user is someone who wants to import a photo and burn it into a trinket.

[@UnreasonableSteve]

In the cuts/layers panel, you can see where he's set the different layers to fill or line (effectively raster vs plotter as you've called them). As long as your input file is vector, it's really easy to switch between the two, and to get the thick lines for visible text on metal, you're gonna want to fill the shapes

[@melgross]

Right now, I do all of my engraving mechanically. I’ve been thinking about a laser unit. It’s difficult to decide on what to get. The largest size I need to engrave is a standard rack panel width of 19”, but just to about a 0.5” from each edge. The height would be about 4 rack high, or 7”, again not quite to the edges. So, ok, that’s a fair size. So what will do that? Well, a fiber laser will, but for that size, we’re talking about $4 to $7 thousand! Ah, that’s a bit much as I’m not charging for what I do. CO2 machines tend to not be terribly reliable over the long term. But they will work, just not very well for metals. So laser diodes are next. There are different photo laser colors. Mostly from blue to violet. So the question is, you’ve used stainless, which I do use for parts, but rarely panels. Will this work with aluminum, particularly anodized? If so, would black anodized work better, as it might easily burn through the black layer? Have you tried? Oops! I typed this right before the end of the video where you mentioned anodized aluminum. Still interested to see black anodized.

Nice and interesting video! I put a diode laser on my CNC and had some similar problems with laser marking. I used LaserWeb to generate G-code. Which worked but it was not ideal with a lot of wasted time. Then I just used the horizontal milling in Fusion 360 and set the end mill to 0.1 or 0.2mm depending on the material. To export, I modified the post processor to turn off the laser at every linking move. This greatly increased speed of my projects. Also, the spindle speed can be changed to set laser power. In my case 24000 rpm = 100%.

[@GoughCustom]

My understanding is the CerMark stuff's main ingredient is molybdenum disulfide, and that other 'moly' sprays can be used as a substitute!

It's a combination of "molybdenum compounds" and silica, so it fuses into a glass. The pigment may be the same, but the overall chemistry is different.

Chuck the screws into a drill (head out) and head (hehe) over to your belt sander. Take off enough of the head (drill running at low speed to make it even) that you can still screw the plates down, but any excess is out of the way of the laser.

[@xlr8436]

The line outline warning less than fill isn’t cause the line after is a cut but rather that a slower outline will give a more crisp outline cleanup mark if you’re doing shapes/text on things like leather/wood/etc. If your outline is a little slower than fill, it just defines it a little more in a lot of cases. Also for frame, you can check your frame with the outer layer turned on. Then just before you engrave toggle the button to turn off that layer from outputting in the top right.

Great channel James, I like the way you use a lot of different types of machines for your projects. I have picked up a several tips that I can use at work where I use some of the same type machines and do some CAD work too. I do have one tip for aligning your parts for laser etching. To save time on the alignment you could have the laser burn the outline of the part on a scrap piece of wood or cardboard then put your part on the outline instead of having to frame it several times to get it lined up. You would probably need to be able to set an origin point at the laser for this to work good and I don’t think I saw you do that, not sure if you can on your machine. Keep the videos coming!!

[@Clough42]

Good tip. I'm not totally sure about this particular laser. It de-energizes the motors as it sits idle, so I'm not sure how well it keeps position. But I have a project coming up that requires very precise alignment, and that's a fantastic way to do it.

[@Clough42]

Nice work as always James. One thing could be better I think from a graphic design point; the border outlines are too close to each other which makes them connected for a human eye. If the separation is just a few millimeter wider it looks cleaner and more defined as separate areas. Small tip. Thank you! Best, Job

[@Clough42]

It's a design challenge, because if you make the borders smaller, you start running into the connector lock nuts, and this is a visual challenge as well.

[@vincei4252]

Nice result, James. The path for rendering in the tooling app was kinda weird. Since the laser can move in X/Y why does the software insist on raster scanning the entire surface like a TV CRT beam. Doesn't make much sense. As mostly vectors that are aligned with the axes this should have been a very rapid cakewalk. Is it done like this because of concern for repeatability of positioning? Strange. Keep on trucking my man.

Something fun you can also do is cover the metal in powder coat paint powder and run it. The laser will melt and adhere the powder to the metal exactly where it points.

Is the power level critical for getting this to work? Because the laser can also be used to remove powder coat for marking.

@@Clough42 it's not too bad but you need to clean the part well with acetone preferably first and dry it, then use like a credit card to put a thin layer on the top. Then go pretty fast with a low power and it should work well. I have done it a few times. Pretty cool

James, very neat toy. I know a gunsmith that uses something very similar, but more specialized, for marking gun barrels with his trademark and caliber. There is one niggling little detail that stuck out to me me, and I have no idea why -- but it's an inconsistency in your marking design. In the "Power" and "Servo" frames, you have the axis labels (A, Z, X and Y) inside the outline, and in the "Home" frame, they are outside. I know that it makes absolutely no difference, but it's not consistent, and it offends my OCD! 😉

I'm not a designer. It looks a hell of a lot better than a dymo labeler, though.

Very nice looking panel! Another laser engraving technique is that lasers cutters can burn through surface anodizing on aluminum.

[@gregfeneis609]

EG If those electrical panels were alu and had a black anodized surface, the laser engraving would look silver/alu color.

The 450 nm UV laser will mark steel but only very superficial. A 1064 nm IR fiber laser will mark steel much better. I have made a few mistakes, marking the wrong text on a part and some simple scotchbrite or emery cloth did not get the text removed. It took some time to get the engravings removed using some coarse grit paper. Cermark is great stuff but I can't get it to work with the fiber laser. It does however work well with my regular CO2 laser (which is also IR but with a 10,600 nm wavelength) Marking anodized aluminum is fun. You can play with the power and get it from a slight grey all the way to a bright white on black anodized aluminum. I do also mark on other coated/painted metals. Colored dibond is one of my favorite materials but I also use other stuff that I just spray paint, engrave/mark and then spray with a clear coat for added protection.

Very informative video, easy to listen to.

man the Adoble illustrator instructions were very valuable or me!

Is that a 20 or 40w? I tried looking up which laser was 400nm but couldn’t find it.

Wow, what an amazing introduction !🎩
