MakerBot Replicator new 3D printer

Our friend Bre Pettis has introduced the MakerBot Replicator, his company's latest open source 3D printer. It can print much larger objects than the cupcake-sized creations spewed by previous models, and with the optional Dualstrusion feature, it does two colors. The fully-loaded Replicator is $2k. Congrats, Bre! "Introducing The MakerBot Replicator"


  1. I wonder if you can get/make conductive feedstock… if so the “dualstrusion” feature opens up rather a lot of possibilities.

    1. Though having said that, it would be really hard to make reliable connections to it, and the conductive plastic would have quite a lot of electrical resistance, so it wouldn’t be quite like having a 3D printed circuit board. Oh well, it was a nice thought while it lasted :)

    1. Argh.  Logging in swallowed my long-winded post.

      Ultimaker’s extruder uses a flexible shaft drive, which is springier and harder to reverse, but that might be compensated for in software.  So quality might be as good, but may take more tweaking.  Just a guess.   But it’s lighter and will be faster for that.

      Many people base their purchase off of shipping cost.  Ultimaker will be cheaper in europe, Makerbot in the US.

  2. Damn you makerbot! i love you and hate you so at the same time, I’ve still never gotten my first one working 100% and now you come out with a new one….

  3. I have to admit- I really enjoyed building our makerbot- it gave us an intimate knowledge of how it worked, and removed the fear of breaking it if we ever have to get back inside it to repair/tweak something.

    That being said- still wrestling with calibrating the dang thing so having it come all put together is a bit of a bonus ;-).
