flexMendel

This printer is designed to be very easy to assemble, with a minimum number of parts. It is very easy to use and easy to hack. It has a smaller footprint and larger print area than its predecessor, the Aluminum Mendel. It is very precise and efficient. The tradeoff is that it requires some machined parts that may be hard to source if you do not have access to a vertical mill. For this reason, it is not a good choice for beginners. The y and z axes use machined UHMW inserts that slide directly on the aluminum extrusions. This gives a rock-solid print bed with very low friction. All forces acing on the printer are carefully balanced for smooth printing. The low mass extruder is very precise for accurate, clean prints.
