8. Automator | Part Remover Overview 11/15/16
“Guillotine” style part remover design
Two linear actuator powered sliding blade
1.4kN max force per actuator x y z

9. Automator | Part Remover Operation 11/15/16z
Steel Blade
PTFE Pads
Build Platform
Linear Actuator
Blade pulled by actuators across build platform
Blade does not contact build platform
PTFE pads eliminates blade lock-up
Sprung bottom rail allows for PTFE wear
Does not need to be sprung if PTFE pads are replaced every 1000 cycles y
Bottom Rail Spring
Blade to actuator bracket removed for clarity
