As humanity moves closer to our vision to settle the moon, and then Mars, the ability to generate critical infrastructure “on site” in space becomes increasingly important for cost control, timelines and safety. 3D printing with indigenous Mars materials in an autonomous robotic way, before humans set foot on Mars may be the key. My team has been participating in the NASA Centennial Challenge to 3D print a Mars Habitat for the past 3 years to develop this concept and technology.
In this presentation I will first illustrate how our adventures started from the garage, while being unfunded and understaffed. We borrowed key hardware components, including a pasta machine that substituted for a clay printer extruder and a 10 foot robotic arm, from industry and academic partners. We even generated our own Mars regolith simulant based on volcanic basalt rocks we handpicked in Northern Israel.
Despite many challenges, ranging from limited access to materials, short deadlines, and zero dollars in funding, we were able to print the first physical deliverable, which significantly outperformed the NASA required minimum in initial mechanical testing. In delivering the second physical deliverable, we struggled with optimizing the curing time and heat exposure to the printing nozzle. However, we overcame operational challenges, recruited new team members from around the world, and increased the printing accuracy.
The BubbleBase team was recently “adopted” by Caltech, in a strategic move to enhance our US presence and increase manpower working on the project, especially in the field of robotics and autonomy. The talk will elaborate on additional challenges currently facing the team, including: merging teams from different disciplines and cultures, technology challenges in material science, robotics and civil engineering, funding requirements, and operational challenges. It will conclude with the team’s plans for the future (on Earth, and on Mars) and how you can follow our work and get involved in the project.
