This is the idea to completely make the frame of the reprap out of PLA/ABS (or similar materials). This should be
achievable by replacing the metal smooth rods of former designs with plastic ones. By that i do not mean solid rods of
plastic but more likely pipe like shapes with some stabelizing inner build like a number(#)-sign or maybe a cross(+) would
even suffice. Since this design will most definately have some stability issues we will have to think of a way to bring
stability in without increasing difficulty of assembly too much as well as keeping amount of needed material as low as
possible (and thus hopefully cost as well;).
To give the Plastobot the ability to reproduce the rods itself i thought of splitting long parts into smaller ones and
have a click system, like many plastic products nowadays have, connect them. Wether or not this option has too much of a
negative effect on stability and how to reduce it remains to be seen in tests.
The rods will be made of plastic with some sort of inner support.
That is how i imagine the rod to look like.
This is the top of the rod with the little pins of the click system on either side.
The bottom with the holes for the pins.
