Just a quick update as some of you may have already seen via John Biehlers Blog I have been working on a mini Ultimaker style printer with the goal of making a truly portable printer. This came about after taking my Prusa on holidays and finding it too big to travel with and not required for most things you would print on the go.
A few notes on its design and construction.
200mm x 200mm x 300mm (225mm x 225mm x 300mm with reinforcements brackets installed, see picture)
102mm x 102mm x 120mm (100mm x 100mm x 110 usable)
LM8uu linear bearings on all axis (currently using Triffid Hunters printable LM8uu's for testing with excellent results).
Fully printed case (12 main sections, 12 connectors, 14 axis parts, 5 optional reinforcements, 3 piece custom extruder).
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 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.
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).
11- 608 bearings
10 - LM8uu's or 8 - LM8uu's & 4 - LM8Suu's
2m - 8mm smooth rod
250mm - 6mm threaded rod (1/4" threaded rod) and two nuts
60 - Socket head screws (Allen head)
4 - Nema 17's ( Nema 11's / Nema 14's should also work as it takes very little torque)
Your favorite electronics.
Thanks go to John for his beautiful picture.
It now has a name "Tantillus"
