Interesting Video - Delta Robot

I just spotted this on youtube. It looks a really neat project and is also arduino based.

M&M sorter

I like it!

Neat machine indeed! Not suitable for RepRap'ing though since the resolution is enough for what it should do but otherwise quite course. Wich also raises the question: Do we REALLY need the resolution for our own repstapping projects ?

Yes the quest for ever greater resolution for FDM can be a bit of a waste. After all its really the extrusion of the molten plastic that is the restriction on a cartesian reprap in XY. The Z axis can cause some problems.

It looks like there are a few delta robots in the pipeline that may be setup for FDM. It will be interesting to see the parts they produce. My guess is that it wont be linear dimension problems, but twisting and bowing of the parts that will be the biggest issue.

Our's (Thorsten and mine) still doesn't print... Twisting and bending sure is an issue that shouldn't be taken light-hearted. In our design i explicitly took my time for a good calibration setup to minimise those effects to the min. But reality will tell in the end!
