CNC Halftone Pictures

at 5:38 am. Filed under DIY Hacks


Metalfusion from Finland has developed an interesting method of creating CNC routed halftone images using a single v-bit router bit. Just like a news paper prints images using dots of ink this process produces dots of different sizes by plunging the v-bit to varying depths. He has developed the software which allows normal images to be converted into files that are ready to be cut on a CNC machine. It isn’t a quick process though for example the apple image is recreated with 3774 individual dots.

    very cool

  2. MrLebowski Says:

    Really cool artworks, and the program is nice too, but it generates a dxf file with circles , I wonder how (what program to use) to convert these circles to different drilling depths depending on the angle of the tool.

    very cool! nice idea too!

  5. Nicholas Says:

    Very awesome! I’m wondering if this would ever be available to purchase.

  6. London Says:

    @Nicholas: All you’d have to do is purchase or make your own CNC.

    This should work with lasers, too, including the low power ones from DVD burners on plastics or foam. Basically, I think you won’t even have to change the software. CNC setups with lasers don’t usually have the third axis but the time that the controller “thinks” it plunges the V-bit into something will be translated into dwell time of the laser. The deeper the cut the controller “thinks” it’s making, the longer the dwell time and so the larger hole the laser will burn/melt in the material. My CNC setup ( http://elabz.com/laser-cutting-diy/ ) is in a bit of a disarray due to an impending laser upgrade but I will definitely try as soon as I get it running again!

    Hi Nick,

    That is actually something that I plan to try in the week(s) to come if I can find a bit of spare time. Stay tuned. :)

    What material are you using to put the picture on? Is it just a piece of wood painted black?

  12. deanb Says:

    I have no idea how to use the software. how do I open a jpg?

    Definitely imagine that which you stated. Your favorite reason appeared to be at
    the web the easiest factor to take into account of. I say to you, I
    certainly get irked at the same time as other people think about concerns that they plainly don’t realize about.

    You controlled to hit the nail upon the top as smartly as outlined
    out the entire thing with no need side-effects , other people can take a signal.
    Will likely be again to get more. Thank you
