Significance of the 3D Printed Habitat Challenge
“One of our primary goals for NASA is to Enable Humans to Live and Explore on
Planetary Surfaces. This competition will help us to answer fundamental
questions and possibly to develop capability needed to deliver on that ambition.”
"In-space manufacturing technologies such as the 3D-Printed Habitat technology
are some of NASA's greatest challenges."
“About a month ago I attended a National Science Foundation sponsored
Workshop on Additive Manufacturing for Civil Infrastructure Design and
Construction. This was a world-class international event with a total of 171 people
that attended the workshop, with 17 from industry, 23 from government, and 131
from academia. This particular competition was mentioned many times because
of the excitement it has generated. The world is watching you!”

More than 1,400 traditional media hits
3DPH Challenge received more than half of the total
hits to our program websites in 2015, ~55K.
The program continues to receive requests from
media outlets asking for information, images,
interviews, etc., almost weekly.
Phase 1: Design | Media Traditional products: media advisory, press
release, web features
Social: A huge push on social media was made
to increase registration, because of which we
gathered the largest pool of applicants CCP had
ever had, at the time.
Outreach: CCP used stage time and an exhibit
space at the NYC Maker Faire to promote the
challenge and to award the Phase 1 checks.

alignment
• Measure inner diameter
• Bonus points awarded for roof
• Hydrostatic test
• Fill habitat element at rate of at least 10 L/min to a depth of 500 mm

• Focus is on creation of construction materials from indigenous
materials and mission waste (polymer recyclables which would
otherwise be “nuisance” materials)
• As in phase II, a sliding materials scale rates construction material
selection based on relevance to planetary missions– Teams are no longer penalized for use of imported materials (those that would be
transported from earth specifically for construction purposes) as they were in phase II,
but indigenous materials are scored higher than nonindigenous materials on the sliding
scale
• No penalty for water
• Material feedstock must be a blend suitable for the competition (see FAQ 3.12)
– Polymer scale is based on frequency of use of polymeric materials in packaging for the
International Space Station (ISS)
– Aggregate scale is based on relative availability of materials on the planetary surface
Materials
Basalt, considered an indigenous material, is
rated highly on the sliding scale for habitat
construction materials

Materials scoring
The material mix will be assigned a score by summing the products of the 3DP
factor of each material and the amount of that material (by %weight) present in
the formulation.
Video and documentation evidence of the material selections and mixing
process will be required for the judges to be able to validate the mix and award
the appropriate points.
For phase III, a maximum of 100 of 1100 points at each construction level will
be allocated to material selection.

• Additional materials testing is required only if
material mix has changed since previous submission
– Teams must submit information on new material
mix (constituent materials and percentages by
weight) sufficient to assign a new 3DP factor
– Durability testing of specimens (freeze/thaw test
per ASTM C666) from certified test lab
• This test takes 2-3 weeks to run.
• Scores assigned based on reported
durability factor
– Compression test per ASTM C39
• If materials are unchanged from the previous level’s
formulation (and the previous level’s formulation was
deemed acceptable by the judges), they can carry
over to this level

written report)
✓ Document material mix for level 3 and calculate 3DP factor

Subscale Habitat Competition
• Face to face competition - invitation only
• Limited to no more than eight teams
• $800,000 in prize money available with a
$500,000 top prize!
• More than just printing a 1/3 scale habitat –
requires significant work by the teams leading
up to the actual event

Caution for Teams in the
Full Competition
The 1/3 scale model of the habitat must be printed
in a 4.5 meter by 4.5 meter area at the head to
head competition.
Total time allocated to printing activities is 30 hours
over three days

“Pre-work” to Consider
• Optional pre-printed components per rule 8.2.11
• Material mix and durability test results
• Three bending test samples per rule 8.9 printed before
the competition and brought for testing
• Documentation for judge review per rule 8.11
• A BIM model with structural and pressure retaining
elements at LOD 400 and to LOD 200 for MEP & ECLSS
which corresponds to the structure that will be printed at
the event submitted along with the proposal defined in
rule 9.2.
