Matthew,
I agree about the heat and warping - Trotec has a unique algorithm that helps with the process so that you dont hit the same area repeatedly. Yes - a 10" field is hard because you have to...

Sorry for the delayed response guys...I don't recall the exact number of passes but it does take minutes using a 20 watt. .030" into aluminum is very deep and took about 12 minutes, but again that...

Hi Ian,
If you have the right laser, then a laser is great for engraving deep into steel. Please see the photos below. The first is is .030" deep into aluminum and the second is .010" deep into...

Russell,
For .25” acrylic - try:

100% power
.2% speed
1000 hz
Focus into the material almost halfway (you can program -0.1 into the Z Offset column in the Material Settings and this will be...

Russell,
That machine is solid. My machine is a Trotec 45 watt also from 2004. I never have done anything to it and I currently use it for demonstrations to show how new machines run. It still...

Jon - please email me the file.

Bryan,
You are correct, marking metals with a fiber does not create smoke as a CO2 laser does with wood, paper or plastics. One of the important factors of exhaust is keeping the optical path from...

Larry,
Anodized aluminum was a thought since it sounded suspiciously familiar to UID applications. Poly coating typically refers to polyurethane when doing UID tags. I couldn't help but do a...

Larry,
Could your requirement be for UID at all? The specs you gave look very suspicious that your customer needs UID or something similar. UID typically requires anodized aluminum tags with...

I also saw the Laser Photonics machine. There are a small limited number of companies that actually produce a "fiber laser". Laser Photonics purchases the 5000 watt laser and attaches it to their...

Michael,
Yes, A 150 watt Coherent CO2 laser is where you would start. This would be slow, but you could do it up to a limited thickness. Higher power is better. Coherent tubes have higher peak...

Dave,
Delrin is a plastic - more on the soft side. This is usually the material used to make embossers as well other industrial types of items. It will engrave and cut nicely with a CO2 laser. I...

John,
The Chinese laser is a DC excited CO2 laser tube - as opposed to RF excited. Don't worry, I am not trying to scare you as it should work just fine, but it may work a bit differently since...
