Mendel vs. Darwin

Mendel is the latest generation RepRap machine. Mendel supercedes the first version, which we call Darwin. For RepRap Version I "Darwin" instructions follow this link.

Mendel has the following key improvements over Darwin:

  • Bigger print area, smaller machine footprint
  • Improved constraint on the z-axis to eliminate jamming
  • Better axis efficiency
  • Simpler assembly
  • Capacity of tool changing

This video illustrates these improvements:
