This page will document some changes I am planning to make to a version of Mendel that has the following properties:

  • 1. as simple as possible, but no simpler
  • 2. maximize build space
  • 3. minimize print/construction time
  • 4. minimize cost

The main focus is optimizing Mendel to increase possible reproduction rate while not losing any build volume and maybe increasing it. A big part of that focus will be simplicity (Not necessarily self-reproduction but ease of reproduction). Some quotes that inspire me:

  • “Simplicity is the ultimate sophistication.” - Leonardo da Vinci
  • “Everything should be made as simple as possible, but not simpler.” - Albert Einstein
  • “Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.” - Antoine de Saint-Exupery

Things Being Considered

This involves many designs already made by Vik and others currently working on the Mini-Mendel development. One area where I differ from the current Huxley/Mini-Mendel development is that there are certain design complexities in both that I would like to eliminate. (i.e. X-axis belt arrangement, all three axis bearings, etc...) It may involve some of the following:

  • 1. reduction in number of bearings
  • 2. adding more low cost ubiquitous vitamins
    • R/C car gears for the extruder, springs for the bed, etc...
    • (I know this is backwards from a lot of other development)
  • 3. optimizing all parts for plastic volume, print time, etc...
    • looking at fill patterns, hole shapes (square vs round), etc...
