Aztec Star Wars on bamboo chopping board
« on: June 25, 2018, 04:47:51 PM »
I thought Iíd have a go engraving the Aztec Star Wars design thatís been floating around various laser engraving sites on the web, to see how well the Elekslaser would perform. Quite impressed by the results of the 2W A3, although it did take 4+ hours. Bamboo chopping board, 220x220mm, feed rate 1000, power 255, diagonal engraving, 0.2 resolution (127ppi) PNG with T2 Laser. Nice deep and sharp engraving too, with a slightly defocused beam.

I lucked into choosing the size of the engrave as I thought the details might get lost in the physical resolution of the bamboo. Any smaller and linework like the cockpit outline on the X-wing would've been overburnt. If anyone's trying a similar thing, I'd recommend getting an even larger board. 240x240mm would probably resolve the tiny details better.

Oh, and no tape and no air assist. That seems to work best for me for doing chopping boards.

Looks great. What did you start with? How did you scale it? Variable intensity or multiple passes for deep cuts?

The source image is a Corel Draw file with also a PDF. I've attached the PDF. I don't have Corel Draw and I couldn't work out how to fill the outlines into coloured fills in Illustrator so I ended up loading the PDF into Photoshop. Since it was a vector, I could rescale it to whatever size I wanted and I ended up a dimensionally huge 9GB Photoshop file that I used the Paintcan fill to work with. However, I suspect I could've made it smaller but at 600 ppi, and the fill brush would've still figured out how to fill the really fine pointy edges. The burn was at full intensity/power for the duration of the engrave and only a single pass.

I've attached the PDF and CDR if you want to have a play.

Wow, more than "quite impressed" that's amazing.

It doesn't look like it's from a cheap 2W diode laser, which speaks volumes to your skills. Well done.

Thanks folk. Now that Iím convinced that the 2W can perform to such a nice level, Iíll work with coming up with some original designs for Fatherís Day in Sept here in Oz. The barís been set pretty high. (-; Kudos to the original artist.

wow, very impressive especially the fine detail.
Do you plan to finish it with oil or varnish? I find that the black soot comes off quite quickly
so in order to keep the contrast I need to varnish it making it useless as a chopping board.
Chopping board oil works to a certain degree but is not as good at keeping the contrast as varnish, I find
anyhow!!

Iíve already oiled it with mineral oil (aka ďliquid paraffinĒ here in Oz.) It still looks pretty impressive. Hereís a photo of the oiled version.

@ianchia - your post cost me about 100 hours of tweaking the astec star wars file to fit a 100x100 slate coaster or mirror. The result is great. Removed about 80% of the trace, made most lines 1 pixel wide, and spent considerable time on making the mask and space ship symmetrical.

Picture is mirror with crude flashlight for backlight. Have circular neo-pixel ring but need a box and cpu to hold them.

Did a prior etch on slate but it does not photograph nicely. No problem giving these away.

That looks great @ggallant571. You certainly did a *lot* of work to shrink that intricate design down to fit on a 100mm tile. Well done. I donít suppose you could take a nicer photo so we can admire the effect in a better light 💡 (-;

As for mine, I played a little bit with some additional typography on a second piece after I gave the original away.

I am 3D printing an enclosure for a 24 element neo-pixel ring, 3.7V battery, switch, and Arduino Mini Pro board. Sloooooooow printer!!! Will post new pictures when working (I hope).
