Advantages

  • Designed by Nophead (Good parts/service available from Nophead, very detailed, high quality instruction manual, shared his design through his blog: http://hydraraptor.blogspot.com/2011/12/mendel90.html )
  • Sturdy structure means faster speeds in the x and y directions
  • Easy to assemble
  • Not a lot of calibration is required
  • Open frame design, allowing it to be worked on easily and mostly disassembled without falling apart
  • Ribbon cables are used to prevent cable tangling and friction
  • Less need for adjustment
  • Great reviews from Mendel90 owners

 Disadvantages

  • Critical hole dimension and spacing
  • The platform moves in y as well as z directions
  • MDF is the cheapest material that could be used to build the frame but changes in weather may cause it to expand or contract. Aluminum is a better choice but it’s more expensive (Materials that could be used for frame: MDF, polycarbonate, acrylic, Dibond, aluminium).

The budget for this project using Nopheads Mendel90 kit would be around $1100.

If we buy our own parts our budget would range from around $600-$800 depending if we could get some of our parts printed out and the material we use for the frame.
