Grad Student Makes 3D Printing Pen with Haptic Arm

Yeliz Karadayi’s “Guided Hand” thesis project is basically a 3D printing pen attached to one of those haptic interface robotic arms. It will make sure that users 3D print recognizable shapes, while still offering the freehand feeling and look of a handheld 3D printing pen. Primarily it can be set to containment mode, which provides the user with an invisible set of boundaries that prevent the pen from moving outside of them. It can also be set to boundary exclusion mode, which prevents the inside of the model from being printed, while allowing the outside to be built up around it.
