In my obsession dreaming of a folding RepRap, I finally started to make one (end of 2011), after 5-7 months of development, since 2012, I'm able to travel with it around the town/country/world :) (adventures pictured on flickr / youtube). Maybe a few thousands were made, from kits or by self-sourcing : FoldaRap_Hall-of-Builds / google-maps.

Specifications

  • Printed Parts: 47
  • Non-Printed Parts: 266
  • Material Cost: around 400-500g
  • Cost: 300-600 €
  • Printing Size: 140x140x140 mm (or 5.5"x5.5"x5.5")
  • Resolution : XYZ = 0.0065 mm (depends of your stepper drivers and the micro-stepping, e.g.: 1.8° motors + 1/32 microstepping = 152-153 step/mm for the rack version)
  • Tolerance : 40mm = 40mm +/- 0.05 mm
  • Speed: 75-500 mm/s (print-travel, max speed tested yet, 40mm/s for nice corners)
  • Accuracy : 0.05mm (50 microns is the lowest layer height tested yet)
  • Volumetric speed : 0,4mm = 4mm3/s ; 0,5mm = 8mm3/s ; 0,8mm = 10-12mm3/s (usually)

Special Features

  • Foldable !
  • Based on standard parts, easy to reuse/recycle
  • 1.75mm Direct Driven Bowden Extruder ; fixed on the x-axis for less hysteresis and higher z-print
  • Low energy consumption (40-110W)
  • Footprint : 210x350 mm / Total volume : 335x350x360 mm / Folded : about 335x500x98 mm / 3-4kg
  • Printed sliders (PLA) on anodized aluminium extrusion

Community

R&D

FoldaRap x.x

  • rubber wheel on alu and encoders ? (idea suggested by Xevel years ago)
  • 140x140x140mm and 200x200x200mm version
  • rack on the Y-axis (to remove the last belt/pulley)

FoldaRap 4.0

  • if external PSU : use the room left to embed a RaspberryPi / or even simpler now : use a controller with wifi capabilities (Duet, AzteegX5, etc.)

FoldaRap 3.5

  • below 15°C the sliders seems to require a little more force to move (another reason for replacing all the nema14s)

FoldaRap 3.0

Combining old and new ideas, plus the little changes in every parts, and that is good for a new release :)

FoldaRap 2.5

Changes from the 2.1 :

  • nema 17 for the extrusion (instead of a nema 14)
  • small blower to cool the plastic (instead of a 40mm axial fan)

FoldaRap 2.1

FoldaRap 1.0

Huxley size

Mendel size

  • 5 300mm
  • 7 400mm

From the VertX to a whole printer, it's the next big project I started to dream of, some months ago, because I want to have a folding RepRap for travels/exhibitions/conferences that only need to be plugged to print (even if the Huxley is already not bad for that).

  • Foldable (first inspiration came from a folding ladder that my father have, then the Bonsai_RepStrap, this thread where Mendel90 first appeared, and from my Pocket Engraver structure)
  • Few threaded rods (I first thought about aluminium extrusion, but finally I'll assemble printed parts to make the frame, which is also good for replication/changes/scaling)
  • Easily scalable (can be 300x300x300 or 50x50x50, as we want).
  • Sells Mendel style Z-axis (one motor as I like to be able to manually tweak the Z)

More Inspiration

Some details that I found interesting or related or want to integrate to this idea of a foldable machine...
