RepRap: Blog

Just before he left to Starve in the New Zealand Wilderness Ed did a new RepRap design because he "had to get it out of his head". It was a mini version of Mendel. You can see it on the left in the picture above - a still from
Josef Davies-Coates' short documentary on the Bath RepRap Lab. The machine uses M6 threaded rods and M3 nuts and bolts (as opposed to the M8/M4 used on Mendel) and NEMA 14 steppers. The reprapped parts are about 30% of the volume of those for Mendel, which is to say it could reproduce three times faster.

This is a completely unsupported design for the moment (we haven't got the time...) but we have put the STEP file for it in the RepRap repository at

https://reprap.svn.sourceforge.net/svnroot/reprap/trunk/mendel/mechanics/mini-mendel

because it's so neat, and some of you might like to play with it...

Here's a close up rendered by M.BrittCrane:



Thanks!

On reflection, I think that putting the material spool underneath is not a good idea: it tends to jam. Better to have it on a separate reel above (which would make the machine even smaller).
