NASA’s 3D Printed Habitat Challenge: Phase 3 Level 4 Final Results

▶ NASA's 3D Printed Habitat Competition Vision
• Advance the automated construction and materialstechnologies needed for fabrication of habitats on a planetary surfaceusing indigenous materials and mission recyclables
• Terrestrially, these technologies stand to revolutionize the construction industry by automating labor intensive processes and enabling rapid fabrication of large scale structures
• World’s population predicted to increase from 7.6 billion to 11.2 billion by 2100 (47 % increase) 👉• https://esa.un.org/unpd/wpp/Publicati...
• Requires aggressive construction practices to satisfy increased demand for affordable housing


▶ Potential of 3D Printing Technologiesfor Space and Earth
• Autonomous systems can fabricate infrastructure (potentially from indigenous materials) on precursor missions
• Can serve as a key enabling technology for exploration by reducing logistics (i.e. launch mass) and eliminating the need for crew tending of manufacturing systems
• Also has potential to address housing needs in light of unprecedented population growth
• Affordable housing globally
• Military field operations

▶ Overview of the 3D Printed Habitat Competition
Advance additive construction technology to create sustainable housing solutions for Earth and beyond
• Phase I. Design - Prize Purse Awarded: $0.04M
Develop stat-of-the-art architectural concepts that take advantage of the unique capabilities offered by 3D printing
• Phase II. Structural Member - Prize Purse Awarded: $1.1M
Demonstrate an additive manufacturing material system to create structural components using terrestrial/space based materials and recyclables.
• Phase III. On-Site Habitat - Prize Purse Awarded: $2.0M
Building on material technology progress from Phase 2, demonstrate an automated 3D Print System to build a full-scale habitat.

▶ Phase III, Virtual Construction Competition
Teams had to use Building Information Modeling (BIM) software.
Overall Winners:
• Virtual Construction, Level 1
• Minimum of 60% of the information required for construction of the pressure retaining and load bearing portion of the habitat
• MEP and ECLSS design (LOD 100)
• Structure and Pressure Retaining Walls/Components (LOD 300)
• Virtual Construction, Level 2
• 100% of information required for construction
• MEP an ECLSS design (LOD 200)
• Structure and Pressure Retaining Walls/Components (LOD 400)

MEP: Mechanical/Electrical/Plumbing
ECLSS: Environmental Control and Life Support Systems
LOD: Level of Design

Evaluation criteria: LOD, system information, layout/efficiency, aesthetics, constructability, and BIM use functionality

▶ Phase III: Level 4 - Virtual Construction Competition Final Results





00:00 ● Intro



01:18 ● Hassell+ EOC’s concept

Hassell+ EOC’s concept relies on a swarm of wheeled mining robots to excavate and collect regolith for processing into feedstock. Concurrent printing along the x-y footprint of the structure by the fleet of robots enables rapid and efficient fabrication. The resulting Mars habitat has a contoured structure intended to complement the surrounding environment.

02:28 ● 1st: SEArch+/ApisCor-New York -$33,954.11

The habitat is an inward facing arch design (a hyperboloid) with two layers. High density polyethylene (a polymeric material with good properties for radiation shielding) functions as the inner layer, while the exterior is regolith. Radiation shielding is accomplished via overhangs.

7:00 ● 2nd: Zopherus–Rogers, Arkansas -$33,422.01

Lander structure encloses the printer, providing a pressurized, thermally controlled print environment for processing of the extracted materials (ice, Calcium Oxide, and Martian aggregate) into feedstock and fabrication of the first habitat module.


11:45 ● 3rd: Mars Incubator –New Haven, Connecticut -$32,623.8

A series of habitats arranged in a hub and spoke design, with the largest, primary volume at the center. Panels in the design consist of polyethylene and basalt fiber. The habitat in this design is not fabricated via continuous additive manufacturing; instead, additively manufactured panels are mechanically assembled via robotic manipulation.
