Discussions about a RepRap for the space resulted in the conclusion that for maximum durability we should build a Mendel Max.

Current Status

Please consult with Martyn before ordering/purchasing any parts.

The Space MendelMax currently requires :

  • Motors - 5 needed for single extrusion, 6 if we go fancy dual extrusion - eMakershop a possibility
  • Smooth Rods - Metal Supermarket, all 8mm we have decided
  • Electronics - SmoothieBoard or 4Pi arm-based electronics are ideal, but mostly only about to be released
  • Extruder/Hot End - I have a spare heated nozzle ready, there's a CPU heatsink we can probably retrofit, and with the quick-fit extruder, that may be all that's needed, we will see.
  • Heated bed* - I have got a slightly iffy quote from china (direct import) for $45 each for 2 with $40 delivery
  • Possibly some more LM8UU bearings

(*)A heated bed is not strictly necessary for PLA but makes it a lot more reliable, and essential for ABS

Suppliers

  • Martyn R for printed parts. (Printing in progress)
  • Misumi for aluminium extrusions (collected from Bob C 2012-08-18).
