Desert Lab
Our desert proving ground for bioconcrete block technology — where bioconcrete is stress-tested against 120-degree summers, flash floods, and sandstorms to prove that digitally fabricated shelter can outperform conventional construction in the harshest conditions on Earth.

Core Technology
3D-Printed Bio-Concrete, Desert Proven
Bio-Blocks are precision-manufactured interlocking building units made from 80% bio-based materials — including recycled construction aggregate, volcanic pumice, and mycelium-stabilized binder. Each block is 3D-printed in 45 minutes, interlocks without mortar, and achieves 3,100 PSI compressive strength. At the Desert Lab, we are proving this technology performs under the most punishing conditions on the continent.

"We are not competing with concrete. We are replacing it with something the planet can actually afford."
Passive Comfort
82 Degrees Inside When It Is 120 Outside
Bio-Block walls act as a thermal battery. The 12-inch interlocking wall assembly absorbs daytime heat and releases it 14 hours later — maintaining interior temperatures within a 12-degree comfort band year-round, without any mechanical heating or cooling. Compared to standard CMU block construction, Bio-Blocks reduce peak interior temperature by 18 degrees and cooling energy demand by 94%.
Growing in the Desert
3.9 Inches of Rain, 365 Days of Food
Bio-Block wall geometry includes integrated greywater channels that route building runoff directly to drip irrigation. Combined with the shade microclimates created by Bio-Block structures, our desert permaculture program proves you can grow meaningful food yields even in one of the driest ecosystems in North America — using the building itself as the water harvesting infrastructure.
- Integrated greywater channels in block geometry
- 85% water recapture from building envelope
- 24 drought-adapted food species in trial
- Bio-Block shade structures create 15F cooler microclimates
"The desert does not forgive bad engineering. That is exactly why we test here."
Performance Data
Bioconcrete Block Thermal Performance
Our 12-inch bioconcrete block walls demonstrate a 14-hour thermal lag, maintaining interior temperatures within a 12-degree comfort band while outside temperatures swing over 55 degrees. Compared to conventional concrete block, bioconcrete blocks reduce peak interior temperature by 18 degrees.

Fabrication Pipeline
From Digital File to Standing Wall
The Bio-Block fabrication process from mix design to finished structure. Every step is optimized for desert conditions and off-grid deployment.
Mix Design & Calibration
Each bioconcrete block begins with a custom bioconcrete mix: 60% recycite aggregate from construction waste, 20% volcanic pumice for thermal mass, and 20% mycelium-stabilized binder. The mix is calibrated to local humidity and temperature before every print run to ensure consistent layer adhesion.
3D Printing & Layer Deposition
Our gantry-mounted extruder deposits bioconcrete in 8mm layers at 120mm/s. Each block takes approximately 45 minutes to print. The interlocking geometry — dovetail keys on all four faces — is printed in a single pass with zero post-processing. We print 32 blocks per day on a single machine.
Dry-Stack Assembly
Bioconcrete blocks interlock without mortar. The precision dovetail keys create a continuous thermal bridge-free wall system. Two workers can assemble a 10-foot wall section in under 4 hours. The dry-stack method means walls can be disassembled and blocks reused — a first for concrete construction.
Thermal Curing & Instrumentation
Blocks cure for 14 days in the desert sun, reaching full 3,100 PSI strength. During curing, we embed fiber-optic temperature sensors at 2-inch, 6-inch, and 12-inch depths. Every wall becomes a data-generating research instrument, streaming thermal performance data 24/7.
Solar & Systems Integration
Bioconcrete blocks include integrated conduit channels for electrical, plumbing, and ventilation — printed directly into the block geometry. Solar mounting rails attach to precision-printed anchor points. The result is a fully off-grid building envelope with zero chasing or retrofitting.
