        Brian,

        I normally start with an end mill which works only in X & Y on a depth of
        for example 5mm and this one takes away most material and does first the
        rough work. In the last finishing step I use a 60 degree V-bits for all the
        edges and fine details and this one goes three dimensional X, Y & Z because
        you need the fragile sharp top of the V-bit to cut out the sharp edges and
        small details. I use several softwares including signmaking software very
        similar to ArtCam to finally come to a WinPC-NC file on which this
        CNC-router runs.

        Buying large panels of new Corian is indeed a problem but some authorized
        fabricators are selling their scrap on eBay at reduced prices and some less
        popular colors can go really cheap. In Europe there are some companies where
        you can order cut to size panels in all the different colors but this is
        still expensive. Another possibility could be 1 ¼" thick PVC which is used
        as a replacement for wood like this AZEK To Mill (ATM) which is made in
        sheet sizes of 4 ft x 8 ft:
        http://www.azek.com/viewProduct.php?id=12
        I don't know this ATM material here in Europe and haven't tested it but it
        looks interesting at first sight and is probably cheaper than Corian.

        Regards,
        Erik

        Erik,
        Thank you for posting that video. Do you use the v-bit for all
        your cutting or do you start with end mills? Also what programs are
        you using? I have a friend that makes brass dies for foil printing
        and he uses ArtCAM. I've watched him program images and text a number
        of times and it seemed fairly simple. The cost of ArtCAM of course is
        a problem.
        I just acquired a piece of Corian after hearing from another
        artist that it prints well. Other than its cost it seems to be the
        perfect candidate since it's designed to be machinable. Here in North
        America it's only sold to authorized fabricators who don't normally
        sell it in sheet form. A laminate of 6mm Corian and MDF planed to
        type high could be the perfect match combined with CNC technology, no
        variation in qualities or grain to worry about. I see on Wikipedia
        that Corian has several competitors, who I'm guessing may be cheaper.
        I'm also experimenting with 3mm white styrene sheet laminated to MDF
        which is considerably less expensive.
        Keep us posted on your progress and thank you for the pictures and
        video, they have inspired me!

          I've used a program called V-Carve to cut wood on a CNC. Its a great
          program: easy to use and pretty inexpensive. I can import eps files
          made on a mac and easily set the parameters in V-Carve. It drives my
          little Roland engraver directly with no post processor or dxf
          conversion.

          Website is http://www.vectric.com/

          I still haven't committed it for use on any projects but it seems to
          do a really nice job.

            I've been looking into CO2 laser engraving systems. Looks to be a
            great solution. You could make wood or metal plates. Very precise,
            lots of control and horribly expensive. The company that makes an
            affordable smaller laser engraver will have a whole market to
            themselves I think.

              Erik,
              I was excited to see your post about this new material that was
              thick enough to be planed down to type high. The website showed what
              appeared to be a solid dense plastic, so I quickly found the
              distributor and then a store that sold the product, but unfortunately
              it's not suitable for printing. It's most common use is as a
              replacement for lumber to make decks, one side is smooth while the
              other side has a faux wood grain finish, however even the smooth side
              is covered with very fine pits. It appears as though it's a mixture
              of plastic and sawdust or some kind of filler to reduce costs, but it
              was worth a try!

                It may be on the pricey side for large sheets though.
