Was surfing around at Ikea the other day and came across some 6 x 10 bamboo cutting boards for $4.00 that I thought might be nice for some smaller laser engraving projects. Could also be used for CNC projects but sometimes these have voids in them so i thought laser engraving would be better
Looks great! Such a great idea using Ikea’s cutting boards! I’m dying to have a laser engraver. My husband gave me the choice between that or the CNC. I chose the CNC. He said if I can earn enough to pay off the CNC then he’ll consider the laser. I think he wanted to make sure I’d stick with it. Well I have an love it! Even if it’s only been like three weeks…haha!
and an acute V endmill such as the 30 degree Amana #46202-K we have in:
can cut very fine details when configured as a V endmill — I bought an even pointier one, but have only used it for punching holes in leather before cutting it w/ a drag knife (one a bit larger than the Stingray).
I love the APTITLIG boards from Ikea. I can get two cell phone stands and a business card holder from a single board and they are so cheap to buy. I find I have inconsistent results with laser engraving bamboo though. Some bands will engrave dark and others light. I only have a diode laser though so it is not all that powerful.
That is good to know. I honestly get inconsistent results with a lot of wood varieties where the grain can have big differences. I find oak and elm are also really bad for it. I just tried to engrave a picture in oak and decided to do something else. Ended up carving a 3D image instead. It was just too inconsistent across the face of the board with the laser image. Some areas looked good while others looked horrible. Anything that requires a lot of variation in laser power across a large surface in oak, bamboo or elm I have just stopped trying. Solid burns are at least somewhat better but even then can look like a gradient across the face.
Another option for cutting boards is a deep laser engraving with an epoxy fill. This was a scrap board I played with, to see how deep I needed to engrave and to test bleeding. There’s a bunch of air bubbles in it, and I have board oil from another board leaking on the top areas, but I was really happy with how sharp I could get the image. When I tried v-carving the image, the bit would break the delicate details, whereas the laser keeps everything nicely defined.
Here’s a great on line site where you can make your own 1, 2, or 3 letter monograms and download as a svg, png, or pdf file. Totally free but you must register and you are limited to 10 downloads a day.
So I was having issues with tear out and things when attempting to do find details on my cnc as I do not have a laser cutter. I have just discovered that I can run a engraving bit, and pocket the image at .5 mm to attain the same results as a laser engraver or cutter. The only difference is there is no black burn marks
Bamboo cutting boards come in two varieties. Bamboo is basically a hollow tube and is a type of grass. The two varieties are end grain and face grain. The end grain boards have the bamboo cut into pieces and then smashed together with the end grain on the top and bottom of the cutting board. The other variety is a face grain type. The long strands of bamboo are smashed together . The picture of @BrownMagic looks like a face grain type cutting board as well as the @rbreininger one.
End grain cutting boards are preferable because they hide the knife cuts if used as a cutting board. If making a wall hanging that does not matter much. So if possible try for the end grain cutting boards.
Here is a picture from Amazon of an end grain bamboo cutting board.
