[How To Mechatronics] capitalized on this and built a SCARA robot arm using 3D-printed parts and common 3D-printer components. The basic SCARA mechanism is a two-link arm, similar to a human arm.

SCARA arms are one of the options to get around this, as demonstrated by [How To Mechatronics], with his SCARA laser engraver. This robot arm is ... 3D printed frame parts. The arms lengths ...
