What do you get when you combine the extreme density of sintered Hawaii basalt with a high-powered water jet cutter? Extreme precision.

Last month, PISCES sent a sample of its strongest sintered basalt to Bear Machinery, a compact manufacturing facility in Honolulu that produces high quality components for the medical, scientific, military, commercial, astronomy and aerospace industries—including instruments for many of the Maunakea observatories.

Technicians at Bear aimed an in-house, 55,000 psi water jet cutter to the block, producing perfect cuts in a variety of shapes (shown above left). They also branded a piece of the sample with the PISCES logo using a laser engraver (above right).

Test results of have shown PISCES’ sintered basalt samples exceed the structural integrity of specialty concrete, yielding compressive strengths of 30,000 psi and flexural strengths of 6,000 psi.

Combining these blocks with precision cutting technology could produce an extremely durable, non-corrosive and sustainable building material.

PISCES and Bear Machinery now plan to form a Memorandum of Understanding (MOU) to explore further possibilities for collaboration.
