Notes on the Sarrus linkage
It has seemed to me that a self-replicating 3D printer might well utilise linkages, which are easier to construct, rather than accurate guide rails
The problem with most of the linkages is, however, that they are 2D. By the time you either reinforce them to provide guidance in three dimensions they become either complex or bulky. For that reason, I've long been enchanted by the Sarrus linkage.
I've found watching it move is positively hypnotic. Since commissioning Tommelise 2.0 and carrying it over to production work I've had some time to consider what sorts of concepts belong in a third generation Tommelise. Of course, the Sarrus linkage came up almost immediately.
Of course all that depends on the scale...
