SCARA 3d printers

The SCARA acronym stands for Selective Compliant Assembly Robot Arm or Selective Compliant Articulated Robot Arm. By virtue of the SCARA's parallel-axis joint layout, the arm is slightly compliant in the X-Y direction but rigid in the ‘Z’ direction, hence the term: Selective Compliant.
The second attribute of the SCARA is the jointed two-link arm layout similar to our human arms, hence the often-used term, Articulated. We will see how this concept develops. Nice new innovation after Delta approach.

Here is the first video of SCARA used for 3d printer by ttsalo (http://github.com/ttsalo/Armstrong-SCARA)




Here is RepRAP Morgan, a more sophisticated SCARA FDM 3D printer developed by Quentin Harley
