Spotted in the MAKE Flickr Pool, John Biehler’s excellent photo of a tiny prototype fused-filament 3D printer designed and built by Fraser Valley RepRap User Group member “Brad,” aka Sublime. Brad’s posted a detailed description on one of his personal blogs and on the RepRap wiki, but hasn’t published the physibles yet. The “vitamins” ( non-printable parts) consist of four stepper motors, eleven skate bearings, ten linear bearings, a couple pieces of smooth and threaded rod, assembly screws, and the standard RepRap electronics. The build volume is just a bit over one cubic decimeter. He calls it “Tantillus.”

    Unless i’m missing something, the build volume (from one of the sources) is 10cm^3: “Build Area: 102mm x 102mm x 120mm (100mm x 100mm x 110 usable)”

    One cubic centimeter is positively TINY.

    Looks like a great little machine. If the price is equally tiny, this might be the machine to introduce a lot of people to 3d printing with. Especially considering the possibility of expanding the print volume.

    I’ll be keeping an eye on this one for sure.

      Disregard that first bit, apparently i misread “decimeter” and can’t edit my post.
      Never used that particular type of measurement, just cm^3 and m^3 (don’t know why though).

      1. Haha, yes, “decimeter” is a less commonly used unit of measure, but still perfectly valid! Nice use of the term really.

    What’s that blue glassy material the print bed is made from? I keep seeing it used in various builds but haven’t been able to find out what it is.

      Its just 6mm blue acrylic (plexi glass)
