We’ve previously posted about DIWire, an Arduino based machine that bends metal wire into 2D or 3D shapes. Now the folks at Pensa have uploaded the bill of materials, code, and models of the custom parts for 3D printing so that you can get started building your own CNC wire bending machine… in case one of these is out of your price range.

    This is excellent that they released the designs. The actual control code is mentioned in several places in the MAKE post and their own blogs, but I have been unable to locate anything other than the BOM and the 3D models – no actual source code for the Arduino or Processing side of things. Anyone have any links?

    • Matt Richardson

      Craig, if you go to the Google Code repo, click “Source” then “Browse.” They’re saved as .txt files for some reason.

        Thanks, Matt. It was not apparent when I first looked under the Source tab and didn’t see anything available jump out at me. Marco Perry from Pensa has also been very helpful (and quick) in helping me get to the bottom of this. Thanks again.

    Anybody have an estimated cost of this BOM? This would be a totally build for our hackerspace…

      After a little consulting with the McMaster catalog and some sourcing for the oriental motors/drivers, I figure the parts will run a little north of $1200, 75% of which is just the stepper motors and drivers. This does not include the spools of wire, they run around $80/330′ spool.

    Man what a cool Idea, pretty “simple too” Maybe instead of a cnc foam cutter for lost foam casting, I could wire frame, then Skin (and remove the wire) a plaster form, and pour. Probably easier to create hollow castings….very cool idea.

    I’m interested to know the costs of materials, some idea.?

    This may be stupid question, but what is wire bending used for? What kind of projects can this machine help make? Cool project anyway.

      One thought off the top of my head is outlining the relatively complex shape of the wing for a wind generator. The wire can then become the support structure for either the wing itself or a fiberglass mold. No need to shape anything by hand and experimenting with changes would be relatively quick and cheap. The same basic idea could apply to any reasonably sized fiberglass mold (like for a dashboard, or a special project box). I can think of tons of little doodads one might want to print, like a phone stand, or a cable organizer, or a cup holder, etc. The artistic applications are pretty much unlimited (provided wire is involved somehow).

    I love it. Have you done any research involving a 3rd axis?

    dose any buddy have pensa contact no? i try to to mention no on web but not conected?
