3DGS + ROBOTICS:
In-place joinery application within 3DP tensile support system and system assembly 

2023 - 2024 Spring
Academic + Individual Work
University of Michigan, Ann Arbor - MS Digital and Material Technologies - Robotic Engagement
Instructors |  Wes McGee

Concept/Idea
The project proposes an asssembly of a tensile structure with 3DGS and introduction of a robotically printed support system with in-print joinery for tension-only structures. The novelties of the project is twofold: Tension structure with 3DGS & support system with robotic 3DP (1) and joint introduction while printing (2). 

Why robotic printing?
  • large scale
  • securing the joint within layers while printing
  • carbon fiber materiality in compression forces
  • flexibility of printing the neglecting force in the force direction given in the equilibrium

Method
Pellet extruder end effector on KUKA KR120 

Material 
PETG + Carbon fiber mix
