Tantillus
Introducing Tantillus. The portable self replicating mini printer.
Status
Feb 27, 2012
- Alpha 1 is finished and printing. Geometric Object Deposition Tool Blog
- Beta 0.1 under construction.
Feb 9, 2012
- Alpha unit assembled and ready for testing.
Design goals
- Portable
- Self replicating
- Compact
- Fast
- Printable frame
- Expandable
Specifications
Outer dimensions:
- 200mm x 200mm x 300mm (225mm x 225mm x 300mm with reinforcements brackets installed, see picture)
Build Area:
- 102mm x 102mm x 120mm (100mm x 100mm x 110 usable)
Features
- LM8uu linear bearings on all axis (currently using Triffid Hunters printable LM8uu's for testing with excellent results).
- Fully printed case.
- It can print all of its own parts.
- Designed to use J-head hotend (eventually).
- 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.
Planned additions:
- Extension panels to allow it to expand itself by 100mm in any or all directions (incomplete as of yet).
- The ability to daisy chain two machines together to mass produce parts while only using one set of electronics (both machines would produce the same parts at the same time).
