    • There's 'a thing' - a very cool 'thing', a very expensive 'thing' that can be rented for about £5k a week. I want one to spend a few days just making <these.detritus
    • otherwise <that takes ages to make, layer by layer slowly ablating top surfaces. Can't put in too much power with every pass, otherwise it all just burns to shtdetritus
    • http://lasermake.co.…detritus
    • its a nice effect.omg
    • you're looking to rent a laser?omg
    • at those prices, you could just buy your own.omg
    • No, I have a laser - what I'm after is a specific type of device, very rare and costing upwards of three quarters of a million to buy.detritus
    • I've been trying to work out how to make one, but I'm not smart enough.detritus
    • that's a lot of money to make a wood grained tile. I'm guessing you're looking to make something much bigger.omg
    • 1000s of wood grained tiles :)detritus
    • bet you could do it better with a cnc router to avoid the burning.omg
    • No, a CNC has no way of understanding where the lay of the wood's inherent contours are.detritus
    • Sand-blasting and lasering are discriminate - they only affect the softer or more burnable portions of the wood, thereby describing its character.detritus
    • I have wondered at creating a bitmap contour and CNCing or lasering a piece of wood, but the problem is that a surface scan doesn't represent what is underneathdetritus
    • so even a mill, or two, or three under surface, and already your contour map doesn't match the actual grain and form of the wood through its bulk.detritus
    • so how would you get rid of the burning?omg
    • the discoloration and smell is horrible.omg
    • you don't go at it full whack :)
      the laser can be set fine enough to just ablate the top percentage of a millimetre, so you just repeat downwards..      detritus
    • ..sort of like the inverse of a 3D printer.

      And yes, the smell can be awful - walnut is sickening :\      detritus
    • that hardwood must take longer. I'll rarely work with wood in my laser due to the smells.omg
    • i wish i could, but maybe someday.omg
    • Eh? What sort of laser do you run.. and what for? That your business?detritus
    • It's used primarily for business. Prototype research, manufacture low run in-house product design work. It's not used as a laser service for other businesses.omg
    • It's a 45w laser. What your laser used for?omg
    • Epilog? I run a laser cutting servicedetritus
    • Oh, those are nice. Fslaser is the brand I choose.omg
