Repemaker - new replicant 3d printer developing

Hi, my name is José Gémez I'm architect from Spain and from the last month i'm developing a new reprap 3d printer. The goal is make a machine with the x-y axis similar of the ultimaker but with printed parts. The prototype works yet. Al the parts are very easy to find: open belts, smooth rods, mdf wood, and I want that the machine cost the same price that a pusa 2. I'm redesigning almost all the parts to make strong in some points and optimizing the z-axis.
The prototype measure 40cmsx40cmx40cms and its very easy to transport...



And some videos working:

Nice! I think I would have to cut some windows in it.

Are there 3 Z axis screws? I can only see 2, and that seems unstable.

I'm redesigning the z axis, the first try (actually) I want to put 2 screws and a third LM8 but now I turn 90 degrees the z-axis... I'm printing the new z-axis... with the repemaker

Jose, why dont you use spectra fishing line to move the axis (take a look at the tantilus subforum, or contact sublime, he has done a great work on this)

It looks like you're using linear bearings on the rotating rods, they aren't designed for that and will fail very quickly.
The ultimaker uses brass bushings on rhose rods for that reason and Tantillus uses PLA bushings for the same reason.

I don't see how these rods are rotating.

I get it now! Removing the centres of normal bearings and polishing them a bit makes some quite good - very cheap bushings.

Hi I have worked in the project the last days... Now it works very well. The key is the LM8 linear bearing, with the lm8 it not works but with the igus bearing works ok.

wunderbar !

Hi,
are there any updates?
Im very interested in a printable ultimaker.

Yes the printer is fully functional. Now I'm making some minor changes, I want to upload all the documentation in a near stable state. The key that I said before is the igus bearing... I suppose that with a bronze bearing it must work best...

The project is almost finish...



I have started to upload the info to the wiki.

I have upload all the info to my web: http://www.makealo.com with a guide and a BOM with all the materials and printer parts. I have upload to thingiverse too: http://www.thingiverse.com/thing:138063 the printer parts and the laser cut.

The second prototype with GT2 pullesy and belts.
