  • Beta 0.1 printed in ABS was unsuccessful due to ABS warping. A special version was designed with openings to relieve stress but it too was prone to warping and cracking in ABS.
    • All parts are successful in PLA and have passed many hours of printing.
  • Alpha 1.0 of laser cut version complete.
    • Multiple copies of Laser cut Beta 0.1 being assembled for testing.
  • Public release estimated for End of April

  • Alpha unit assembled and ready for testing.

Design goals

   √  Portable.
   √  Commonly available parts and materials.
   √  Self replicating.
   √  Compact.
   √  Autonomous printing.
   √  Printable frame. (Printable version only)
   ≈  Custom interface shield. (Currently hardwired)
   ≈  Larger version of laser cut model. (Tantillus Plus)
   ≈  Belt upgrades. (For those of you who just have to have belts)
   ∅  High speed copper hotend.
   ∅  Expandable. (Printable frame only)
   ∅  Daisy chainable. (Two machines running off the same electronics)
   ∅  Dual extrusion for expanded frame and Tantillus Plus.
         √ Complete | ≈ Current Development | ∅ Future Development


Specifications

Outer dimensions: Printed version

  • 225mm x 225mm x 300mm

Laser cut version

  • 240mm x 240mm x 300mm

Build Area:

  • 100mm x 100mm x 100mm


Features

  • Fully printed case. (retail version uses laser cut case)
  • It can print all of its own parts.
  • Designed to use J-head hotend.
  • Internally mounted extruder with bowden cable.
  • External power supply to allow for battery operated use.
  • Uses an interesting drive train: low cost wire rope (fishing wire) or High test Braided fishing line instead of costly belts (It wraps 5 times around the rod and then goes through a hole and wraps an additional 5 times resulting in no slip). This is a roll on roll off system with a fixed anchor in the middle.
