Nice. I'll have to wait till next paycheck Lucky for me there's still time though. I really think he's going to blow his goal out of the water.by dudesom - Polar Machines, SCARA, Robot Arms
http://www.kickstarter.com/projects/117421627/the-peachy-printer-the-first-100-3d-printer-and-sc?ref=live Is this thing for real? If so, it seems ingenious to me. It also mentions that they will be working with MakerJuice for new types of materials. Edit: It looks like he's going open source with it too. Here's his webpage with the specs.by dudesom - Polar Machines, SCARA, Robot Arms
Actually I think angling the hot ends would help with the drool problem. You'd use a guard, as your original shows, but because the nozzles don't need to individually elevate (because of the angle), the springs wouldn't be needed. You could also attach the guard tightly so that it would flex slightly, providing s decent seal (in my mind). I'm just trying to make it easier for you to build the thby dudesom - Mechanics
Thanks for the link! I think you're defiantly right about the challenge of keeping things hot. Perhaps cold forming would be this system's forte.by dudesom - Mechanics
I'm going to assume you've already thought of this but here it is anyway: You could have your extruders angled, like this microscope has it's lenses angled This should give you plenty of room for a drip guard, without springs.by dudesom - Mechanics
It's ok. There must be something really wrong with my idea I think, because I can't find anyone who's tried anything remotely like it.by dudesom - Delta Machines
After thinking a little more about it, I think that other "blanks" could be used instead of bundled wire. Perhaps Metal Foam or a roll of expanded steel could be used, for instance. The only requirement would be that the blank would have enough space inside for the metal that's being hammered in. Another thought that has occurred to me is that oxidation would be a real problem, due to high surfaby dudesom - Mechanics
I've been thinking about another way that you could do metal forging in another new topic (I probably should have put it here). It involves using a semi porous "blank" that would be heated and then hammered into shape. Hell, you could probably attach a file to the toolhead and use that to shape the metal as well, yielding a full robotic blacksmith. What's your idea AJ?by dudesom - MetalicaRap
Now that metal casting has been improved by 3d printing (lost pla), why not blacksmithing? After looking at other options for machine structure, I think that a polar robot would be best. In my mind, it would be similar to a lathe; the toolhead would be equipped with a hammer and a torch, and the toolhead would be positioned below the workpiece. The spindle would be turned very slowly (comparedby dudesom - Mechanics
That does look interesting. And expensive I wish I could try some of that stuff but I don't see it--along with lasers and arch welders--being in my budget any time soon. At the moment I'm thinking about possibly spot welding and alternative robot designs to the Delta type (lathe style polar looks possible). When I get a little time I'll start a new thread someplace I guess. It's too bad someonby dudesom - Delta Machines
What price range are we looking at?by dudesom - Delta Machines
Well not any printer. Few printers have stationary beds (which I think would be desirable). It's true I could use a rostock but the issue there is that most of the print volume for those machines is in the x axis (if I'm not mistaken). Without a hammer, though, you're right, any bot could do it. I think that for very small wires there would indeed be some flexing issues but, if one used largerby dudesom - Delta Machines
Imagine a Simpson type format robot with the ability to shape metal into near net shape. I propose such a robot could use 2 simple toolheads to accomplish this: One tool head equipped with a wire feed (much like a filament feed) and a cutting solenoid. This tool head would push out wire downward into a bed of styrofoam (or other material that would hold the wire) at varying lengths, depending onby dudesom - Delta Machines
Has anyone considered the rostock delta style of gantry? If used, the end effector could be not only for the laser. It could also deposit and spread the powder layer. It could even have a "rake" on the bottom for such, correct? I just wanted to throw the idea out there, everyone seems to have the Cartesian style gantry in mind.by dudesom - General
Ah sorry then. For some reason I was thinking magnetrons functioned like MASERs. Thanks for setting me strait.by dudesom - MetalicaRap
This has probably been gone over before but I couldn't find it after searching so I thought I'd ask: Has anyone tried sintering powdered aluminum/steel/copper with a microwave oven's magnetron? I just happened to bump into this page today and I read the bit at the end about powders being microwave absorbent when fine enough. Would a vacuum chamber still be necessary?by dudesom - MetalicaRap
Well then I appreciate it. Guess I'll start a new thread someplace so I can bang out the idea a little more.by dudesom - Skeinforge
Oh. I'm sorry for the trouble then..by dudesom - Skeinforge
Thanks everyone, you just saved me a load of time. I am working on a new approach to 3d printing that would only need 1 stepper, a solenoid, and a servo to cut many sheets of paper/plastic/aluminum foil which would be stacked into either a negative of the object for moulding or possibly an object itself.by dudesom - Skeinforge
Can skeinforge export gcode for the outline of an object only? I am working on a unique bot that will only need the outline of an object for its tool path. Right now I'm waiting on parts but would like to either figure out how to use skeinforge or develop my own software in the mean time. Maybe I'm being lazy but I'd rather not do both Thanks for your patience! P.S. Really sorry if this is theby dudesom - Skeinforge
