Etching aluminum works better if you don't use tape and also if you don't use the cotton swab technique. I use spray paint. Raster etch your pattern into the spray paint and then use saltwater bath electrolysis. 12vdc at 3amps only took about 5 minutes of just sitting in the salt water to get a .5mm etch. Afterward, paint thinner or acetone will clean off the spray paint. The etched pattern is razor sharp and looks professional.

What if you made a slurry of powder coating powder and water or alcohol (or other?) then coat the metal and allow to dry then heat with the laser then wash off the unmelted areas. It would be more permanent than paint and could also be a resist for etching. Power coat can be removed with solvent and is very inexpensive. If it works, the process could be a replacement for screen printing on plaques and control panel lettering.

Follow up: I mixed some powder coat powder with mineral spirits and it instantly suspended the powder which I poured on a piece of hot rolled steel and it coated it nicely however the mineral spirits separated from the powder which is probably a good thing. It looks very promising. I will heat it with a torch after it dries and see if it acts like powder coat. Water doesn't want to mix with the powder and alcohol makes it form a glob so there is some interesting chemistry going on but not useful. The process might also be used to etch circuit boards.

@MancaveEffects6 жыл бұрын
Have you tried water with dishwasher soap to break the water tention and mix in the powder, maybe that works? Where do you get the powder for the powdercoating from? For my knowlege powdercoating works by electric polarisation to make the powder stick to the working piece and baking it at high temperatures to melt the coating permanentely to the working piece, but arent there other chemical processes involved too?
@superskeg6 жыл бұрын
I tried a micro drop of Dawn dish soap and the powder did mix with water but it didn't coat as evenly as mineral spirits. The mineral spirit slurry worked very well. While watching the slurry it seemed that a standing edge around the metal part so the slurry would pool might be helpful and maybe make the edge from an absorbent material to wick the mineral spirits away to speed drying. My simple test took about 45 minutes to dry but I waited a couple hours before baking. I have a Harbor Freight powder coating system and have done quite a bit of experimenting but I'm not an expert. It's my understanding that the chemistry of the powder include properties that make it retain a static charge. Once the powder is deposited it melts and coalesces when heated to about 400 degrees and creates a very hard surface, it's a very simple process. Harbor Freight had the lowest cost powder last I checked

I am thinking that you more likely could engrave aluminum, if it is color (black) anodized. I also have some decent experience about Rubylith film as an etching mask. I have seen some statements that the manufacturer chose to combine the previous different tack grade adhesives so the present offering may not protect as well as the hi-tack version used to do. Anyway, the packing tape is a definite no-go in my book.
@MancaveEffects4 жыл бұрын
How do you use the Rubylith film with the laser? I made a followup video trying spraypaint, moly spray and toothpaste.
@InssiAjaton4 жыл бұрын
Mancave Effects Just like you tried with the packing tape. You cover the part with a sheet of the Rubylith film and then burn your trace on it. Finally you etch. The two important issues are that you have to make an absolutely bubble free contact and the fact that the color enhances burning effect, so you can minimize the power. There are videos showing a water spray coating on part, then laying the film which due to the water does not freeze immediately in place. That way you can use a plastic card to squeeze both water and any air out in a systematic way. The film adheres where it meets dry metal. Unfortunately, you still need to somehow -- hair dryer or overnight long time -- let the residual water vapors to completely evaporate before the laser burn. Then my disclaimer. I have not tried the water method. I just trusted direct dry application to cover some border area of my printed circuit board before etching. My reason was only to minimize the amount of etchant use. Worked quite well. I'll try more of the Rubylith when I get my new CNC engraver assembled. The previous application was with Toner Transfer process. Which explains my large border areas that I did not want to etch away. The final board itself was less than 1" by 1". And it was double sided.

I am experimenting with electroplating at the moment. It is pretty hard to even get a troughout conductive layer of metallic paint in the first place.

Mancave Effects I would also like to see how it works in the following related materials: Granite (black is fine), marble, (I have seen it do slate w/o a problem at pretty good speeds), and tile - both glazed and unglazed, such as red terra-cotta as would be typical in a cheap red clay pot, or etching a pattern on unglazed ceramic which could then be glazed to colorize the drawn design and fired. Lastly - how does it work on Anodized Aluminum? (Especially Black anodized, or anodyne on other metals). All of these are important considerations for me in choosing a reasonable cost laser system for small scale business use. While I like the easy upgrades on the K40 I wonder if I would need to upgrade to a 75,100 or 150 watt CO2 laser. Lastly, can you use a combining prism/mirror to add one of the other types of lasers (such as the 10watt 405nm diode or maybe a few watts of green laser) either as a substitute beam or in combination with the IR CO2 beam? (& since they rely on different methods, what advantages might you get in the combination beam) Very curious as to your opinion there. Many thanks for your videos and hopefully your response

Question. I understand Co2 laser wont engrave metal but why can a diode laser at a lower power engrave metal? is it due to wave length?
@MancaveEffects5 жыл бұрын
Flying Karapet, it has to do with the wavelength, here is what i found on a forum: materials have different transmission values for different wavelegnths - while transparent mterials are transparent for VIS (visible = roughly 400nm to 800nm) and NIR (Near Infra Red = 800 to 1200nm) diodes too, all organic/plastic materials are "perfect black" for CO2-lasers (10600nm) or deep UV lasers (below 300nm). So for clear acrylic and wood of some millimeters thicknes you'll better use a CO2-laser. Metal is different - it's highly reflective for CO2-lasers, so you'll need powers of some hundred Watts to get into or through. But it will absorb in the NIR - so most metal marking/cutting lasers are NdYAG- or fiber-lasers with wavelength of 1064 to 1070nm. For the VIS diodes it's a matter of power - the 445nm-diodes with 6Watts of power can be used to mark steel ... but for real engraving or cutting you'll need much more power ...
