Laser Engraving Anodized Aluminium & Annealing Polished Stainless Steel

After exhausting all my previous stock of colorful anodized aluminium and most of my stainless steel, I got some more produced so we can fulfill other customer orders here at CNCROi.com.

We had a run on these which is a great problem to have until more stock arrives, a number of clients got a substantial free upgrade to annealed stainless steel!

These aren’t the only colors that anodized aluminium comes in but it’s a good representative sample of what’s possible!

We can also get anodized aluminium powder coated with any color combination and texture you could want… the nice thing about aluminium is its light weight and compared to stainless steel, a lot cheaper per blank unit. The added bonus of going colored anodized aluminium vs annealing stainless steel is the time, it’s significantly faster for the laser to process through!

The fun part about laser engraving anodized aluminium is that you see lots of cool controlled sparks as the top anodization is vaporized and quickly sucked away thanks to our 2 hp extraction unit!

Depending on how much is removed, you may end-up with long streaks such as what you see above or pointed explosions as you see below.

You also get these special effects with stainless and galvonized steel but not as extreme unless the plate is especially dirty but they are cleaned here at CNCROi.com to get more consistent results.

Stainless steel often has a coating on the surface that’s unperceivable that affects the annealing process so it’s always best to clean it first before production begins.

To wrap things up, if you need some tags, business cards or unique signage that doesn’t wear out over time and is easy to clean while making a statement, your only choice is CNCROi.com!

We’ve got tons of metal stock with more coming on a regular basis and depending on volume, this can be customized further such as larger or smaller plate sizes, thicknesses, riveting holes (different sizes, positions and number) and coating color / texture.

Oh yeah, you can watch a video of both processes happening.

Laser Engraving Beach Pebble Stones: Indepth Material Review

I was asked the other day which types of stones come out best using a CNC laser, the answer is generally the finer the particles making up the stone, the better the results. That didn’t ring a bell with a particular client so I headed to the beach and grabbed a sample of beach pebble stones and brought them back to CNCROi.com HQ.

For good measure, I also found a nicely “wave sanded” piece of glass which surprisingly came out awesome! Before we get going though, let’s see how all these stones began before any laser engraving was performed using our Austrian Trotec Speedy 400 flexx!

In this case, we used our powerful and consistent 110 watt CO2 tube… the light was so bright that even with the filter, it was hard to look at the process. Unlike just about any other material out there that I’ve laser marked, etched, cut, annealed or engraved, stone by far is the toughest to observe though it does look cool with sparks shooting all over the place!

And here is the after shot after these beach pebble stones were blasted with energy! There is a fine powder over the entire bed as you can see more clearly with the business card but some results are already very promising!

They are still rather dirty in the above image so cleaned them up with some water to remove the debris and the results look pretty cool!

So let’s take a look at them a bit closer to more clearly see what worked and what didn’t… as you can see, the particulate size made a massive difference in the results we achieved as well as material composition and distribution. Color also played a role but not in a way I could have predicted though.

What really stands out from the pack is the more weathered the stone, the better the results. I did not clean them before putting them on the bed to be laser engraved, regardless of how dirty or Sun baked they were, the laser would vaporise that better than any cleaning I could do on my part. What surprised me was the darker stones, many came out fantastic while others look hardly touched.

What I did afterwards is allow them to dry.

Alright, now that we’ve seen this bunch of beach pebble stones wet and dry, let’s take a closeup view of a few notables in the pack in more detail.

By far my favorite, this red stone that is actually a worn out brick just came out fantastic after being pounded with the CO2 laser. The contrast is awesome, the depth is perfect and the results just look great!

This black stone is actually a worn out piece of asphalt, I don’t know if it’s natural or man made asphalt but as you can see, the results are far less than spectacular. There is a maple leave on the top middle part (I had plenty of room so got a bit creative) and you can barely make out the CNCROi.com below it. Oddly enough, the detail seems to be easier to pickout from the corner of my eye than looking at it directly, even with just this photograph!

Another stone or beach pebble that’s made up of a bunch of other rocks cemented together over time, you can barely make out my company’s domain (and name) just above the middle. Some particles really like being vaporized by our CNC laser while others, not so much.

Now this one really surprised me, you blast a rock that’s essentially pink and made-up of a bunch of different particulates of different sizes and densities and you end up with something that looks pretty interesting! I guess the surface of this beach pebble stone was coloured after the fact, maybe this is part of an old paving brick!

Looking at some other stones, the results were mixed though predictable, that piece of marble came out interestingly but by far the best was the weathered slate… I’ve done a lot of these kinds of rocks in the past and slate is just a fantastic stone to be laser engraving.

Of course, watch the video to see it all being done yourself!

Incase you missed it, here is another project I did a while back, this time field stone – it had awesome results as you can see that sprung to life after I gave it a bit of water.

The importance of networking and memberships

I wrote a piece for Engraver’s Register about the importance of networking and memberships, you can read all about it here:

http://engraversregister.com/importance-networking-memberships/

CNCROi.com and my other company, CNCKing.com (founding sponsor) were both built on the foundation of education, along with CNCKingdom.com – I firmly believe that a knowledgeable client is one that sticks with you and attracts other clients of the same caliber.

The importance of networking and memberships

I’ve been showing people how to design for their CNC equipment for almost 7 years now and if you go through CNCROi.com, you will see tons of videos showing how lasers perform on various materials for projects all across the map… sometimes literally!

laser engraving the world

CNC machines are great fun, easily among my top 5 toys to play with and it’s rather addicting being always one machine away from being able to build anything… the more you know about CNC machines, the more you want more of them to augment your abilities and provide even more awesome possibilities for your clients. The best part of my adventure in the CNC world is by far getting shop tours, seeing new possibilities and trying to see how those can improve my own flow and potential for clients down the road. It’s a fantastic field to be in and I’m so happy to play my part in expanding this most awesome of fields.
