Which is better for engraving acrylic - diode or co2.

Afternoon all,
Looking at buying a laser which will be predominantly used for engraving pens - most of which will be wood but a few will be acrylic. I am aware of the two main types of laser - Co2 and diode - and of the colour and materials in general that can be used. It seems to me that a co2 laser is most capable, but not as useful than a typical diode laser. The machines I'm looking at are the Makeblock xTool D1 (diode) and the Omtech K40 ( Co2). The former has a large work area, a rotary attachment and such like, where as the `Omtech has a somewhat confined and small area, which I guess will restrict the objects I could engrave. Will the co2 laser 'bubble' the acrylic or leave the edges smooth?

(Even as I type this my wife is suggesting all manner of other stuff that I could use the laser for!)

So user comments on your experience of engraving acrylic pens please?

Thanks.

I have a NEJE laser with an jig attachment for engraving pens that works really well and I have no complaints. I would suggest reaching out to Nancy A McEntire on Facebook as she is the master of all things concerning the NEJE laser or check out her website www.nmclasers.com to reach out to her directly with questions. She knows a ton about this stuff and sells the lasers directly.

My opinion having looked at the two lasers you are considering - I would go with the diode laser. The additional flexibility will pay off for you in the long run and you have a good variety of nice diode laser systems in that price range. Most folks move to a CO2 laser for additional power and you are really gaining no advantage with the model you are looking at over the diode laser.

Personally, I just picked up a D1.

To me, the CO2 laser is more for cutting. It will obviously be able to cut a lot more materials a lot cleaner but you are not looking at cutting. For engraving you would likely have your CO2 below 10% power for its entire lifetime, so you'd just be paying for power you'll never use.

In my mind, if you are super serious about engraving the next step up is a fiber laser but I think that's a rung or two higher up the price ladder than you were looking.

The d1 looks nice.
how is it working out? Their website looks a little ???. Did it ship from China?

Ok, sorry in advance for the drama.
So far it seems like a very nice unit. I got it off eBay for a very good price. The seller mis-identified it as a 10W unit but it was actually 5W so I got a partial refund. Since then, it turns out that the motherboard is shot but, to their credit, xTools is sending a replacement no questions asked. I guess that's a long way of saying I can't actually tell you how it works because mine currently doesn't but, based on having it in hand, I am confident it is well built and should perform nicely. At the very least, I now know for certain that the company stands behind their product even if it was purchased second hand, so that lends confidence as well.

Well balanced reply - and I just bought a D1. Clearly it'll be a couple of weeks until it arrives but from reviews and Youtube I'm confident that it'll do what I ask of it.

Thanks for your input.
