This version of the Delta3 is complete. I have mounted it upside down in a box and added a pen to make it a plotter. I could add a dremel to make it a 3-axis CNC or a reprap nozzle to make it a 3d printer. It has fewer parts than most 3-axis CNC and can be very accurate.
I would like to develop this further to become an education tool for high school students.
I want to make robots for a living. If you'd like to support me in my projects, please send me a message.

With regards to building a
With regards to building a 3D printer out of this I have some concerns about the overall stability and the accuracy of the servo motors. The bases for a good print is pinpoint accuracy to at least 0.1mm (on all axis) and judging by the long rods it seems hard to get the stability and accuracy needed.
That said, I love the Delta robots.

Talk nice!
What kind of an answer & tone is that? "Do your homework. (link)"
Be nice, aggrav8d.
And on top of that, Geir has a very good point!

That's the tone of a guy
That's the tone of a guy who's been inside too long, working on his weekend on a project he hates. Right next to him is a view of a beautiful sunny warm outside, and on the other side are two robots that are begging to be played with. I'm hungry, cold, tired, angry, and when I read his post what I heard was "you can't make a delta3 into a 3d printer!" I've already told him I was wrong.
Thank you for your comment.

First of all, I’m not
First of all, I’m not disrespecting your Delta robot. I think it looks great and operates immaculate.
That said I had a look at the video and the iFab website. If that is done with standard RC servos it’s quite impressive. Still there seems to be a couple of stepper motors for the Z-axis, so just adding an extruder head won’t give you a full 3D printer, or it might give you one with very limited build height.
As the video is the company official promotion video I can’t say that the build quality impresses me. But it looks great and is probably a great conversation piece.

It seems I misread your original statement in a bad mood.
The iFab link was just to demonstrate that a delta CAN be used to print in 3D. It's conceptually no different from a makerbot. While my first machine only gets about 6cm on the Z I fully intend to upgrade to NEMA17s and get ~20cm with longer arms.
You are correct, the iFab uses linear rails and steppers. I could care less about build quality. They get results and that's all that matters.

not seeing how it would be
not seeing how it would be able to make use of the y axis when printing or cnc'ing unless a build platform was added that moved vertically.
Could you perhaps explain this?

you can move up and down
you can move up and down when all three motors turn the same direction (Z)

Very nicely done!Your design
Very nicely done!
Your design looks very good. Nice and stable construction :)
